What is H. pylori and how does it affect the stomach. How is H. pylori infection diagnosed and treated. What are the risk factors for H. pylori infection. How can H. pylori lead to gastritis and peptic ulcers.

Understanding Helicobacter Pylori: A Common Bacterial Infection

Helicobacter pylori, commonly known as H. pylori, is a type of bacteria that infects the stomach lining. This microscopic organism has the ability to survive in the harsh, acidic environment of the stomach, where it can cause significant damage to the gastric tissue and the upper part of the small intestine (duodenum). The infection can lead to inflammation, commonly referred to as gastritis, and in some cases, result in painful sores known as peptic ulcers.

H. pylori infection is remarkably common worldwide, with a large portion of the global population harboring the bacteria. However, it’s important to note that not everyone infected with H. pylori will develop symptoms or complications. In fact, many people can carry the bacteria for years without experiencing any noticeable effects. Despite this, H. pylori remains a primary cause of ulcers and a significant concern in gastroenterology.

The Mechanisms of H. pylori Infection and Its Effects on Stomach Health

H. pylori employs several sophisticated mechanisms to colonize and thrive in the stomach. One of its key strategies involves the production of an enzyme called urease. This enzyme plays a crucial role in the bacteria’s survival by neutralizing stomach acids, creating a more hospitable environment for the microorganism. However, this process comes at a cost to the host, as it weakens the protective lining of the stomach.

As the stomach’s natural defenses are compromised, the tissue becomes more susceptible to damage from digestive fluids, particularly acid and pepsin. This vulnerability can lead to the formation of sores or ulcers in the stomach or duodenum. Additionally, H. pylori has the ability to adhere directly to stomach cells, further irritating the area and causing inflammation.

Interestingly, H. pylori can also stimulate increased acid production in the stomach, although the exact mechanism behind this phenomenon is not fully understood by health experts. This combination of increased acid production and weakened stomach lining creates an environment conducive to the development of gastritis and peptic ulcers.

Transmission and Risk Factors for H. pylori Infection

The exact mode of transmission for H. pylori infection remains somewhat of a mystery to health experts. However, several theories have been proposed based on observed patterns of infection. It is believed that the bacteria can be passed from person to person through oral contact, such as kissing. Additionally, contact with contaminated bodily fluids, particularly vomit or stool, may play a role in transmission.

• Consuming food or water contaminated with the bacteria
• Using utensils or drinking from cups that have been in contact with saliva from an infected person
• Coming into contact with the stool of an infected person, which can occur through improper handwashing after using the bathroom

Certain demographic factors appear to influence the risk of H. pylori infection. Age is a significant factor, with over half of the infected population in the United States being over 50 years old. Race and ethnicity also play a role, with higher infection rates observed among African Americans, Latinos, and individuals from Eastern Europe, particularly those who have immigrated from developing countries.

While H. pylori infection is most commonly acquired during childhood, adults are not immune to infection. This highlights the importance of maintaining good hygiene practices and being aware of potential sources of contamination throughout one’s life.

Recognizing the Symptoms of H. pylori Infection

One of the perplexing aspects of H. pylori infection is that many people remain asymptomatic for years, unaware that they are carrying the bacteria. The reasons for this variability in symptom presentation are not fully understood by medical experts. However, when symptoms do occur, they can range from mild discomfort to more severe manifestations of gastritis or peptic ulcers.

Gastritis, characterized by inflammation of the stomach lining, is a common result of H. pylori infection. Symptoms of gastritis may include:

• Abdominal pain or discomfort
• Nausea
• Bloating
• Loss of appetite
• Indigestion

In cases where H. pylori leads to the development of peptic ulcers, additional symptoms may emerge. These can include:

1. Persistent abdominal pain that may:
   • Be dull and ongoing
   • Occur 2 to 3 hours after eating
   • Come and go over several days or weeks
   • Intensify at night when the stomach is empty
   • Be temporarily relieved by eating or taking antacids
2. Bloating or a feeling of fullness
3. Nausea or vomiting
4. Dark or tarry stools (indicating the presence of blood)
5. Unexplained weight loss

Is abdominal pain always indicative of an H. pylori infection? While abdominal pain is a common symptom of H. pylori-related conditions, it’s important to note that many other gastrointestinal issues can cause similar discomfort. Therefore, proper diagnosis by a healthcare professional is essential to determine the underlying cause of any persistent abdominal symptoms.

Diagnostic Approaches for H. pylori Infection

Accurate diagnosis of H. pylori infection is crucial for effective treatment. Healthcare providers employ a variety of diagnostic tools and techniques to detect the presence of the bacteria and assess its impact on the gastrointestinal tract. The diagnostic process typically begins with a thorough review of the patient’s medical history and a physical examination, followed by one or more specific tests.

Non-invasive Diagnostic Tests

Several non-invasive tests can be used to detect H. pylori infection:

• Blood tests: These tests look for antibodies that the body produces in response to H. pylori infection. While blood tests can confirm exposure to the bacteria, they may not differentiate between current and past infections.
• Stool culture: This test involves analyzing a small stool sample to detect the presence of H. pylori bacteria. It can also identify other abnormal bacteria in the digestive tract that may be causing symptoms.
• Breath tests: These innovative tests involve the patient swallowing a pill containing carbon molecules. If H. pylori is present, it will produce the enzyme urease, which breaks down the carbon. The carbon can then be detected in the patient’s breath, indicating an active H. pylori infection.

Invasive Diagnostic Procedures

In some cases, more invasive procedures may be necessary for accurate diagnosis:

• Upper endoscopy (EGD): This procedure allows direct visualization of the esophagus, stomach, and duodenum using a thin, flexible tube with a camera attached. During an endoscopy, the healthcare provider can observe any inflammation or ulcers and take small tissue samples (biopsies) for further analysis.

Can H. pylori be accurately diagnosed without invasive procedures? In many cases, non-invasive tests such as breath tests or stool cultures can provide accurate diagnoses. However, endoscopy may be recommended in certain situations, particularly when there are concerns about complications or when visual examination of the stomach lining is necessary.

Treatment Strategies for H. pylori Infection

The treatment of H. pylori infection typically involves a multifaceted approach aimed at eradicating the bacteria, reducing stomach acid, and promoting healing of the gastric lining. The specific treatment plan is tailored to each individual based on factors such as age, overall health, severity of symptoms, and personal preferences.

Antibiotic Therapy

The cornerstone of H. pylori treatment is antibiotic therapy. This usually involves a combination of two or more antibiotics to effectively eliminate the bacteria. Common antibiotic regimens may include:

• Clarithromycin
• Amoxicillin
• Metronidazole
• Tetracycline

These antibiotics are typically prescribed for 10 to 14 days, and it’s crucial for patients to complete the entire course of treatment to ensure complete eradication of the bacteria.

Acid-Suppressing Medications

In addition to antibiotics, acid-suppressing medications are often prescribed to reduce stomach acid production and promote healing of the gastric lining. These may include:

• Proton pump inhibitors (PPIs): These medications, such as omeprazole or lansoprazole, work by blocking the production of stomach acid.
• H2-blockers: Medications like ranitidine or famotidine reduce acid production by blocking histamine receptors in the stomach.
• Bismuth subsalicylate: This compound, found in medications like Pepto-Bismol, can help protect the stomach lining and has some antibacterial properties.

How long does it take for H. pylori treatment to be effective? The duration of treatment can vary, but most regimens last between 10 to 14 days. However, complete healing of the stomach lining may take several weeks or even months. Follow-up testing is often recommended to confirm that the infection has been successfully eradicated.

Long-Term Implications and Management of H. pylori Infection

While H. pylori infection can be successfully treated in many cases, it’s important to consider the long-term implications and management strategies for those affected by this bacterial infection. Understanding the potential complications and adopting preventive measures can significantly impact overall gastric health and quality of life.

Potential Complications

If left untreated, H. pylori infection can lead to several serious complications:

• Chronic gastritis: Persistent inflammation of the stomach lining can result in chronic discomfort and increased risk of ulcers.
• Peptic ulcers: These painful sores in the stomach or duodenum can cause significant discomfort and, in severe cases, lead to bleeding or perforation.
• Gastric cancer: Long-term H. pylori infection is associated with an increased risk of gastric cancer, particularly in individuals with chronic gastritis.
• MALT lymphoma: A rare type of lymphoma that can develop in the stomach lining of individuals with long-standing H. pylori infection.

Prevention and Lifestyle Modifications

While it’s not always possible to prevent H. pylori infection, certain measures can reduce the risk of transmission and reinfection:

1. Practice good hygiene:
   • Wash hands thoroughly with soap and water, especially before eating and after using the bathroom
   • Avoid sharing utensils, cups, or other personal items that may come into contact with saliva
2. Ensure safe food and water consumption:
   • Drink water from safe sources or boil water if unsure of its safety
   • Wash fruits and vegetables thoroughly before consumption
   • Avoid consuming raw or undercooked meats
3. Manage stress:
   • Chronic stress can weaken the immune system and increase susceptibility to infections
   • Engage in stress-reducing activities such as meditation, yoga, or regular exercise
4. Maintain a healthy diet:
   • Consume a balanced diet rich in fruits, vegetables, and whole grains
   • Consider incorporating probiotic-rich foods to support gut health

Do dietary changes alone cure H. pylori infection? While a healthy diet can support overall gut health, it’s important to note that dietary changes alone are not sufficient to cure an active H. pylori infection. Proper medical treatment, typically involving antibiotics and acid-suppressing medications, is necessary for eradication of the bacteria.

Follow-up Care and Monitoring

After completing treatment for H. pylori infection, follow-up care is crucial to ensure successful eradication of the bacteria and to monitor for any potential recurrence or complications. This may involve:

• Follow-up testing: A urea breath test or stool antigen test may be performed 4-8 weeks after treatment to confirm eradication of the bacteria.
• Regular check-ups: Individuals with a history of H. pylori infection may benefit from regular gastroenterological check-ups to monitor for any signs of recurrence or complications.
• Lifestyle counseling: Healthcare providers may offer guidance on maintaining a healthy lifestyle to support gastric health and reduce the risk of reinfection.

By understanding the long-term implications of H. pylori infection and adopting appropriate management strategies, individuals can take proactive steps to protect their gastric health and overall well-being. Regular communication with healthcare providers and adherence to recommended follow-up care are essential components of effective long-term management.

Helicobacter Pylori | Johns Hopkins Medicine

What is H. pylori (Helicobacter pylori)?

H. pylori (Heliobacter pylori, pronounced Hel-ee-koh-BAK-ter Pie-LORE-ee) is a type of bacteria that infects your stomach.

It can damage the tissue in your stomach and the first part of your small intestine (the duodenum). This can cause redness and soreness (inflammation). In some cases it can also cause painful sores called peptic ulcers in your upper digestive tract.

H. pylori is common. Many people have it. Most people who have it won’t get ulcers or show any symptoms. But it is a main cause of ulcers.

H. pylori attacks the lining that protects your stomach. The bacteria makes an enzyme called urease. This enzyme makes your stomach acids less acidic (neutralizes them). This weakens your stomach’s lining.

Your stomach cells then have greater risk of being hurt by acid and pepsin, strong digestive fluids. That can lead to sores or ulcers in your stomach or duodenum.

The H. pylori bacteria can also stick to stomach cells. Your stomach can’t protect itself very well. The area gets red and swollen (inflamed).

H. pylori can also get the stomach to make more acid. Health experts don’t fully understand how.

What causes H. pylori infection?

Health experts don’t know for sure how H. pylori infection is spread. They believe the germs can be passed from person to person by mouth, such as by kissing.

It may also be passed by having contact with vomit or stool. This may happen if you:

Who is at risk for H. pylori infection?

You may be at greater risk for H. pylori infection because of:

• Your age. Over half the people in the U.S. with the bacteria are over 50 years old.

• Your race or ethnicity. Almost half of all African Americans have the bacteria. For people who come to the U.S. from developing countries, at least 50% of Latinos and 50% of people from Eastern Europe have H. pylori.

Most people first get the bacteria when they are children, but adults can get it too.

What are the symptoms of H. pylori?

Most people have the bacteria for years without knowing it because they don’t have any symptoms. Experts don’t know why.

You may have redness and swelling (inflammation) in your stomach lining. This is called gastritis.  

You may get sores or peptic ulcers in your stomach or the first part of your small intestine (duodenum). Ulcer symptoms may include belly or abdominal pain, which can:

• Be a dull pain that doesn’t go away

• Happen 2 to 3 hours after you eat

• Come and go for several days or weeks

• Happen in the middle of the night when your stomach is empty

• Go away when you eat or take medicines that reduce your stomach acid level (antacids)

Other symptoms of an ulcer may include:

The symptoms of ulcers may look like other health problems. Always see your healthcare provider to be sure.

How is H. pylori diagnosed?

Your healthcare provider will look at your past health and give you a physical exam. He or she may also use other tests, including:

• Blood tests. These check for infection-fighting cells (antibodies) that mean you have the bacteria.

• Stool culture. This looks for any abnormal bacteria in your digestive tract that may cause diarrhea and other problems. A small stool sample is collected and sent to a lab. In 2 or 3 days, the test will show if you have any abnormal bacteria.

• Breath tests. These can check if there is any carbon after you swallow a urea pill that has carbon molecules. If carbon is found that means that H. pylori has made the enzyme urease. This enzyme makes your stomach acids less acidic (neutralizes them). It weakens your stomach’s mucous lining.

• Upper endoscopy, also called EGD (esophagogastroduodenoscopy). This test looks at the lining of your food pipe (esophagus), stomach, and duodenum (the first part of your small intestine). It uses a thin, lighted tube or endoscope. The tube has a camera at one end. The tube is put into your mouth and throat. Then it goes down into your esophagus, stomach, and duodenum. Your healthcare provider can see the inside of these organs. A small tissue sample (biopsy) is taken if needed. The tissue sample can show if you have the enzyme urease. It can also check the bacteria that is there.

How is H. pylori treated?

Your healthcare provider will create a care plan for you based on:

• Your age, overall health, and past health

• How serious your case is

• How well you handle certain medicines, treatments, or therapies

• If your condition is expected to get worse

• What you would like to do

Your healthcare provider may have you take medicine that kills bacteria (antibiotics).

Other medicines may include:

• h3-blockers. These are used to reduce the amount of acid in your stomach by blocking the hormone histamine. Histamine helps to make acid.

• Proton pump inhibitors. These help to keep your stomach from making acid. They do this by stopping the stomach’s acid pump from working.

• Stomach-lining protectors. These medicines protect your stomach lining from acid and help kill bacteria.

Helicobacter Pylori in Children

H. pylori is a very common cause of peptic ulcers and gastritis in adults, but it can and does occur in children too.

Call your pediatrician if your child has any symptoms suggestive of gastritis. If your child has been diagnosed with an ulcer or H. pylori gastritis, call a doctor immediately if the following occur as they may be symptoms of gastrointestinal bleeding or ulcer perforation:

• Sudden, sharp abdominal pain

• Blood in the stool or black feces

• Bloody vomit or vomit that looks like coffee grounds

What are the complications of H.

pylori?

If you are infected with the bacteria you can get a painful sore called a peptic ulcer. These sores form in your upper digestive tract.

A very bad ulcer can wear away your stomach lining. It can also cause problems such as:

• Bleeding when a blood vessel is worn away

• A hole or perforation in your stomach wall

• Blockage when the ulcer is in a spot that blocks food from leaving your stomach

H. pylori can also lead to stomach cancer.

What can I do to prevent H. pylori?

Health experts don’t know for sure how the bacteria passes from person to person. But having good health habits (hygiene) can help keep you safe. These habits include:

• Washing your hands with soap and water. It is very important to do this after using the bathroom and before eating.

• Making sure all food you eat has been cleaned and cooked safely

• Making sure that your drinking water is safe and clean

Living with H.

pylori

Once you know for sure that you have H. pylori, follow up with your healthcare provider. He or she will do some tests to make sure the bacteria has been removed.

When should I call my healthcare provider?

Call your healthcare provider if your symptoms get worse or you have new symptoms. Call right away if you have symptoms such as bloody vomit, blood in your stools, or black, tarry-looking stools.

Key points

• H. pylori is a type of bacteria that infects your stomach.

• It attacks your stomach and the first part of your small intestine (duodenum). This can cause redness and swelling (inflammation).

• Many people with the bacteria won’t have any symptoms.

• It can cause open sores called peptic ulcers in your upper digestive tract.

• It can cause stomach cancer.

• It may be passed or spread from person to person by mouth, such as by kissing. It may also be passed by direct contact with vomit or stool.

• Having good health habits (hygiene) can help protect you.

Next steps

Tips to help you get the most from a visit to your healthcare provider:

• Before your visit, write down questions you want answered.

• Bring someone with you to help you ask questions and remember what your provider tells you.

• At the visit, write down the names of new medicines, treatments, or tests, and any new instructions your provider gives you.

• If you have a follow-up appointment, write down the date, time, and purpose for that visit.

• Know how you can contact your provider if you have questions.

Gastritis – Better Health Channel

Summary

Read the full fact sheet

• Gastritis is inflammation (irritation) of the stomach lining.
• Common causes include infection, anti-inflammatory medication and alcohol.
• Treatment options include avoiding exposure to known irritants, and medication to reduce the amount of gastric juices.

Gastritis is inflammation (irritation) of the stomach lining. This may be caused by many factors including infection, alcohol, particular medications and some allergic and immune conditions. Gastritis can be either acute (with severe attacks lasting a day or two) or chronic (with long-term appetite loss or nausea). In many cases, gastritis has no symptoms (asymptomatic).

Some forms, including chronic atrophic gastritis, have been associated with an increased risk of stomach cancer. Treatment options include avoiding exposure to known irritants and taking medication to reduce the amount of gastric juices.

Symptoms of gastritis

In many cases, gastritis has no symptoms. Common symptoms can include:

• loss of appetite
• pain in the upper abdomen just under the ribs
• nausea or indigestion
• hiccups
• vomiting
• blood in the vomit
• blood in the bowel actions, if the stomach lining has ulcerated (this turns stools black and is called melaena)
• weight loss.

The stomach

The stomach is an organ of the digestive system, located in the abdomen just below the ribs. Swallowed food is mixed with gastric juices containing enzymes and hydrochloric acid. The lining of the stomach, called the epithelium, is layered with multiple folds. The epithelium is coated with mucus (gastric mucosa) secreted by special glands. Inflammation caused by gastritis occurs in this lining.

Causes of gastritis

Gastritis can be caused by many different factors, including:

• medication such as aspirin and non-steroidal anti-inflammatory drugs (NSAIDS)
• infection with the Helicobacter pylori bacteria, the organism responsible for the majority of stomach and duodenal ulcers
• alcohol
• protracted vomiting
• overproduction of gastric juices, which is a stress response in some people
• the backflow of bile from the small intestine (duodenum)
• some allergic and immune conditions – for example, pernicious anaemia
• exposure to radiation.

Diagnosis of gastritis

Diagnosing gastritis involves a variety of tests, including:

• Endoscopy – a thin flexible tube is threaded down the oesophagus into the stomach. The endoscope is fitted with a small camera so the physician can look at the stomach lining. If the gastric mucosa is reddened, this may indicate gastritis. A biopsy is needed for confirmation.
• Biopsy – small tissue samples are taken during an endoscopy and tested in a laboratory. The pathologist will look for changes, including the presence of inflammatory cells and epithelium damage.

Treatment for gastritis

Treatment for gastritis may include:

• Identifying the cause – once the cause is identified, steps can be taken to avoid exposure. For example, if alcohol is triggering the inflammation, you can abstain or reduce the amount of alcohol you drink. Anti-inflammatory drugs taken to help manage other conditions may need to be stopped or replaced with an alternative.
• Medication – tablets are available to reduce the acid content in the gastric juices. You may need to take these medications for a few weeks or months, depending on your situation.
• Dietary modifications – such as limiting or avoiding alcohol and caffeine, which can irritate the stomach lining.
• No treatment – often gastritis is found by chance during an endoscopy. If Helicobacter pylori is not present, and there are no other features seen on biopsy, there is usually no need to treat the gastritis.

Helicobacter pylori infection

The Helicobacter pylori bacterium causes gastritis and is also responsible for most peptic ulcers. A peptic ulcer is a hole in the lining of the stomach, duodenum or oesophagus. Helicobacter pylori bacterium is thought to be a cause of indigestion and a contributing factor in the development of stomach cancer.

The germs live in the lining of the stomach and the chemicals they produce cause irritation and inflammation. Diagnosis includes a special breath test to check for gaseous by-products of the bacteria. Treatment includes a combination of different antibiotics, followed by breath tests to make sure the medication has worked.

Gastritis of the stomach: symptoms, signs and treatment

Gastritis is a general term that combines several pathological conditions characterized by inflammation and degeneration of the gastric mucosa.

The mucous membrane covers the entire surface of the stomach and plays an important role in digestion. Its glands produce gastric juice, the enzyme pepsin, hydrochloric acid, lipase, hormone-like components, mucus and bicarbonate. These substances are responsible for the breakdown of proteins and fats, protect the body from pathogenic bacteria, and activate metabolic processes.

When inflamed, the mucosa produces less acid, enzymes, mucus and other substances that are necessary for the proper functioning of the digestive tract. There is a risk of developing gastritis.

Gastritis can occur in acute and chronic form. It is important to consult a doctor in time to get a diagnosis and treatment, to prevent complications.

Forms and complications of gastritis

In the absence of adequate and timely treatment, gastritis can cause complications. These include:

• Gastric ulcer. Peptic ulcers affecting the lining of the stomach or duodenum. Peptic ulcer provokes excessive use of painkillers (NSAIDs), and gastritis caused by H. pylori. It is difficult to say where gastritis ends, especially with erosives, and peptic ulcer begins. Apparently, these are different forms of the same process.
• Atrophy of the gastric mucosa – atrophic gastritis. Occurs due to thinning of the mucosa, the formation of fibrosis (microscars) of the membrane in chronic gastritis. With atrophy, the number of active cells of the gastric mucosa that produce enzymes and acid decreases. The absorption of certain vitamins is impaired. Atrophic gastritis is a risk factor for oncological transformation, therefore it requires special attention.
• Gastric bleeding in erosive gastritis and ulcers. It is characterized by irregular breathing, weakness, dizziness, blood in the vomit and stool, black stools, pallor of the skin. If these symptoms appear, you should immediately seek medical help.
• Anemia. Most often occurs due to acute (as described above) or chronic blood loss, for example, with multiple recurring erosions of the stomach. Studies show that H. pylori-associated gastritis and autoimmune gastritis can interfere with the body’s absorption of iron and vitamin B12 from food, which can also cause anemia.
• Vitamin B12 deficiency and pernicious anemia (pernicious anemia). In autoimmune gastritis, a certain protein is not produced that helps absorb vitamin B12, which is necessary for the production of red blood cells and nerve cells. Insufficient absorption of vitamin B12 can lead to the development of pernicious anemia. The same changes occur in the advanced stage of atrophic gastritis of any origin.
• Cancer of the stomach. Chronic gastritis increases the likelihood of developing benign or malignant neoplasms in the gastric mucosa. For example, H. pylori-associated gastritis increases the risk of gastric mucosal adenocarcinoma and lymphoma.

Causes and risk factors of gastritis

• Helicobacter pylori bacterial infection. It is one of the most common types of infections, the infection is transmitted by the fecal-oral route, for example, through contaminated food and water. For the development of gastritis, the presence of Helicobacter pylori infection alone is not enough. It is believed that vulnerability to bacteria is inherited or occurs due to improper lifestyle (smoking, poor diet), medications.
• Pain medications (non-steroidal anti-inflammatory drugs, NSAIDs). Regular and excessive use of aspirin, ibuprofen or naproxen can cause both acute and chronic gastritis, their toxic effects reduce the production of the main protectors of the gastric mucosa. To distinguish this situation from other types of gastritis, it is called NSAID gastropathy.
• Alcohol. Irritates and gradually destroys the gastric mucosa, exposing it to the aggressive effects of gastric juice. Alcohol most often provokes acute gastritis.
• Age. Older people have an increased risk of developing gastritis, as the lining of the stomach thins with age. The elderly are also most vulnerable to infections (H. pylori) or autoimmune disorders.
• Stress. Severe stress associated with injuries, burns, major operations and infections can trigger acute gastritis.
• Exposure to radiation or radiotherapy (due to another medical condition).
• Bile reflux after gastric resection.
• Food allergies such as cow’s milk and soy (especially in children).
• Autoimmune diseases. As a result of autoimmune processes in the body, antibodies are produced that attack the cells that form the lining of the stomach. Autoimmune inflammation occurs, the functions of the protective mucosal barrier decrease. Gastritis associated with autoimmune disorders is called autoimmune gastritis. It is more common in people with other autoimmune disorders, including Hashimoto’s disease and type 1 diabetes. Autoimmune gastritis can also be associated with vitamin B12 deficiency.
• Other diseases. The risk of gastritis may be increased by other pathological conditions, including Crohn’s disease, sarcoidosis, parasitic infections, HIV/AIDS.

Symptoms of gastritis

• Heaviness in the stomach
• Heartburn
• Bloating
• Nausea
• Vomiting

These symptoms may appear or worsen during or shortly after eating. But most often gastritis is asymptomatic.

Sometimes the term “gastritis” is erroneously used to describe any symptoms of pain or discomfort in the upper abdomen, in most cases it is a manifestation of functional dyspepsia.

Stages of gastritis

• Hyperemia. At the first stage of development of gastritis, hyperemia (redness) of the gastric mucosa is observed. This is a protective vegetovascular reaction – vasodilation and increased blood flow in response to a negative effect on the mucosa. Hyperemia is accompanied by edema, this is a sign of the development of inflammation.
• Chronic inflammation, metaplasia, dysplasia. The production of hydrochloric acid decreases, the mucous membrane thickens. Hypertrophy is characteristic of people who abuse alcohol. Inflammation is characterized by the accumulation of leukocytes in the wall of the stomach, prolonged inflammation can change the structure of the stomach epithelium, it can become similar to intestinal, this phenomenon is called metaplasia and may be associated with an increase in cancer risk. But the risk is especially high if a biopsy reveals a violation of the structure of the tissue and cells of the stomach – dysplasia.
• Atrophy. Prolonged inflammation causes thinning of the gastric mucosa, recovery processes slow down, atrophic changes in the mucosa are observed – epithelial cells die and are replaced by scar tissue.
• Erosions and ulcers are a frequent companion of gastritis. Focal and deep changes develop due to a decrease in the efficiency of the mucous glands, thinning of the protective layer, in most cases this is a consequence of exposure to H. pylori.

Treatment of gastritis

Treatment for gastritis depends on the cause. Acute gastritis caused by NSAIDs or alcohol abuse does not require drug therapy, it is enough to exclude these triggers.

In other cases, the doctor may recommend:

• Antibiotic therapy against H. pylori.
• Drugs that block the production of hydrochloric acid (a component of gastric juice) and promote mucosal healing (proton pump inhibitors * – omeprazole, lansoprazole, rabeprazole, esomeprazole, dexlansoprazole, pantoprazole.
• Antacids** (neutralize stomach acid, relieve pain).

* – Long-term use of proton pump inhibitors, especially at high doses, may increase the risk of hip, wrist and spine fractures, may require an osteoporosis prevention program .
** – Side effects – constipation, diarrhea.

Features and benefits of gastritis treatment at Rassvet Clinic

Diagnosis and treatment of gastritis in the Rassvet clinic is carried out in the department of gastroenterology. We use evidence-based methods based on international clinical guidelines. Your main treatment will only begin after a physical examination and all necessary tests and diagnostic tests.

Important. The effect of certain foods or diets on the risk of gastritis has not been proven by studies.

At the Rassvet clinic, we first of all distinguish gastritis from functional dyspepsia. Gastritis is often asymptomatic, but it needs to be treated as it is a slow but sure road to stomach cancer. Functional dyspepsia, on the contrary, is accompanied by many complaints, but endoscopic examination and biopsy do not reveal any pathology.

How gastritis is treated at Rassvet Clinic

To clarify the diagnosis, we use the most modern and accurate equipment and logistical methods. For example, we have built a system for diagnosing gastritis and determining oncological risk according to the OLGA classification. Our endoscopes allow you to perform gastroscopy with multiple magnification and examine the mucosa through light filters, take a biopsy from the most suspicious areas. The biopsy specimens themselves are also evaluated by the histologist according to the OLGA scale, and as a result we get a figure that reflects the risk of oncological transformation in the coming years. Further treatment tactics depend on the value of this figure.

We value the comfort of patients, so in Rassvet you can undergo an examination under anesthesia and in the shortest possible time.

Recommendations of a gastroenterologist at the Rassvet clinic for patients with gastritis

Timely access to a doctor and proper treatment will help keep the disease under control. You don’t need a strict diet. However, the rules of a healthy diet should be observed – do not overeat, avoid foods that irritate the mucous membrane (smoked, fried, fatty), give up alcohol. If you are forced to take painkillers that increase the risk of gastritis, ask if they can be replaced with a drug that is less aggressive to the gastric mucosa (acetaminophen, paracetamol).

Diseases of the oral cavity and gastrointestinal tract

Diseases of the gastrointestinal tract have a complex effect on the health of the entire digestive apparatus, which includes the oral cavity. First of all, this effect is due to a lack of vitamins and minerals, which leads to inflammatory processes, and in addition, it exacerbates existing diseases of the oral cavity.

Of course, in such cases, the treatment of the problem should be comprehensive – you need to contact both the dentist , who will eliminate the manifestations of diseases in the mouth, and the endocrinologist, who will directly eliminate the root of the disease itself.

Let us analyze the main examples of gastrointestinal diseases that directly affect the condition of the oral cavity and teeth.

Gastritis (gastroduodenitis)

This is one of the most common pathologies of the gastrointestinal tract, often found in both adults and children. With gastritis, due to changes in secretion, the acidity of gastric juice increases, and since all organs of the digestive system are directly interconnected, such acidity cannot but affect the health of the oral cavity.

Among the dental symptoms of this disease are pallor and swelling of the mucous membranes, hypertrophy of the papillae of the tongue, dry lips, gingivitis, bad breath and sour taste.

In chronic gastroduodenitis, mild forms of stomatitis, gingivitis , herpes on the lips are characteristic.

In both cases, saliva production is disturbed, which most directly affects the acid-base balance of the oral cavity and the intensity of bacterial reproduction: with a lack of saliva, the risk of carious and periodontal diseases .

Treatment: usually individual, aimed at normalizing gastric secretion, increasing the protective properties of the gastric mucosa and oral cavity. Dental treatment may include a course of antibiotics (as recommended by a physician), treatment of gingivitis and caries , enhanced oral hygiene using special toothpastes to strengthen the gums, and professional oral hygiene , carried out at least once every six months.

Gastric ulcer

Dental symptoms – swelling of the tongue, plaque on the oral mucosa, increased and increased sensitivity of the papillae of the tongue, fever in the mouth, gingivitis and stomatitis .
