Digestive System (for Teens) – Nemours KidsHealth

What Is the Digestive System?

Food is our fuel, and its nutrients give our bodies’ cells the energy and substances they need to work. But before food can do that, it must be digested into small pieces the body can absorb and use.

The first step in the digestive process happens before we even taste food. Just by smelling that homemade apple pie or thinking about how delicious that ripe tomato is going to be, you start salivating — and the digestive process begins in preparation for that first bite.

Almost all animals have a tube-type digestive system in which food:

• enters the mouth
• passes through a long tube
• exits the body as feces (poop) through the anus

Along the way, food is broken down into tiny molecules so that the body can absorb nutrients it needs:

• Protein must be broken down into amino acids.
• Starches break down into simple sugars.
• Fats break down into into fatty acids and glycerol.

The waste parts of food that the body can’t use are what leave the body as feces.

How Does Digestion Work?

The digestive system is made up of the alimentary canal (also called the digestive tract) and other organs, such as the liver and pancreas. The alimentary canal is the long tube of organs — including the esophagus, stomach, and intestines — that runs from the mouth to the anus. An adult’s digestive tract is about 30 feet (about 9 meters) long.

Digestion begins in the mouth, well before food reaches the stomach. When we see, smell, taste, or even imagine a tasty meal, our salivary glands in front of the ear, under the tongue, and near the lower jaw begin making saliva (spit).

As the teeth tear and chop the food, spit moistens it for easy swallowing. A digestive enzyme in saliva called amylase (pronounced: AH-meh-lace) starts to break down some of the carbohydrates (starches and sugars) in the food even before it leaves the mouth.

Swallowing, done by muscle movements in the tongue and mouth, moves the food into the throat, or pharynx (pronounced: FAIR-inks). The pharynx is a passageway for food and air. A soft flap of tissue called the epiglottis (pronounced: ep-ih-GLAH-tus) closes over the windpipe when we swallow to prevent choking.

From the throat, food travels down a muscular tube in the chest called the esophagus (pronounced: ih-SAH-fuh-gus). Waves of muscle contractions called peristalsis (pronounced: per-uh-STALL-sus) force food down through the esophagus to the stomach. A person normally isn’t aware of the movements of the esophagus, stomach, and intestine that take place as food passes through the digestive tract.

At the end of the esophagus, a muscular ring or valve called a sphincter (pronounced: SFINK-ter) allows food to enter the stomach and then squeezes shut to keep food or fluid from flowing back up into the esophagus. The stomach muscles churn and mix the food with digestive juices that have acids and enzymes, breaking it into much smaller, digestible pieces. An acidic environment is needed for the digestion that takes place in the stomach.

By the time food is ready to leave the stomach, it has been processed into a thick liquid called chyme (pronounced: kime). A walnut-sized muscular valve at the outlet of the stomach called the pylorus (pronounced: pie-LOR-us) keeps chyme in the stomach until it reaches the right consistency to pass into the small intestine. Chyme is then squirted down into the small intestine, where digestion of food continues so the body can absorb the nutrients into the bloodstream.

The small intestine is made up of three parts:

1. the duodenum (pronounced: due-uh-DEE-num), the C-shaped first part
2. the jejunum (pronounced: jih-JU-num), the coiled midsection
3. the ileum (pronounced: IH-lee-um), the final section that leads into the large intestine

The inner wall of the small intestine is covered with millions of microscopic, finger-like projections called villi (pronounced: VIH-lie). The villi are the vehicles through which nutrients can be absorbed into the blood. The blood then brings these nutrients to the rest of the body.

The liver (under the ribcage in the right upper part of the abdomen), the gallbladder (hidden just below the liver), and the pancreas (beneath the stomach) are not part of the alimentary canal, but these organs are essential to digestion.

The liver makes bile, which helps the body absorb fat. Bile is stored in the gallbladder until it is needed. The pancreas makes enzymes that help digest proteins, fats, and carbs. It also makes a substance that neutralizes stomach acid. These enzymes and bile travel through special pathways (called ducts) into the small intestine, where they help to break down food. The liver also helps process nutrients in the bloodstream.

From the small intestine, undigested food (and some water) travels to the large intestine through a muscular ring or valve that prevents food from returning to the small intestine. By the time food reaches the large intestine, the work of absorbing nutrients is nearly finished.

The large intestine’s main job is to remove water from the undigested matter and form solid waste (poop) to be excreted.

The large intestine has three parts:

1. The cecum (pronounced: SEE-kum) is the beginning of the large intestine. The appendix, a small, hollow, finger-like pouch, hangs at the end of the cecum. Scientists believe the appendix is left over from a previous time in human evolution. It no longer appears to be useful to the digestive process.
2. The colon extends from the cecum up the right side of the abdomen, across the upper abdomen, and then down the left side of the abdomen, finally connecting to the rectum.

   The colon has three parts: the ascending colon and the transverse colon, which absorb fluids and salts; and the descending colon, which holds the resulting waste. Bacteria in the colon help to digest the remaining food products.

3. The rectum is where feces are stored until they leave the digestive system through the anus as a bowel movement.

It takes hours for our bodies to fully digest food.

Rectum – Our Very Own Waste Dispenser

Have you ever been taught the importance of passing your poop out every single day for good gut health? Maybe yes, because the very first etiquette being taught to children is potty sitting and cleansing their body out by means of removal of their stools or poop.

Poops or stools are the waste materials that are left unabsorbed by our body after complete digestion of the food we ate. Poop, in scientific terms, is called faeces which is a word of Latin origin meaning dregs of the most wasteful or unuseful part. Poop contains around 75% water, according to a 2015 analysis.

Even though the intervals between bowel movements can differ from person to person, regular bowel movements are crucial for a healthy digestive tract. When the desire strikes, people ought to try to poop. They shouldn’t put off or overly force a bowel movement because doing so can cause issues.

Poop Profile 

Where is Poop Stored? 

Poops or undigested food is usually stored in the last segment of the digestive tract, which is the large intestine called the rectum which is then passed out through the anus guarded by muscular walls.

Poop or the waste left at last after digestion is passed through the colon by means of peristalsis (the muscular movement of the alimentary canal), firstly in a liquid state and then is solidified till it reaches the rectum. 

As the poop passes through the colon, water is removed from it which means that the poop gets concentrated while it travels down our digestive tract. This Poop or the stools are stored in the colon until a “mass movement” empties it into the rectum and is removed through the anus once or twice a day. It generally takes about 34-36 hours for the poop to get through the colon. The poop mostly consists of food debris and some bacteria which are present in the duct and help in digestion.

These bacteria are called “good” bacteria and perform various useful functions inside the body, such as synthesis of various vitamins, processing of waste products and food particles, and also providing protection against harmful disease-causing bacteria.

Location of the Rectum in the Large Intestine 

The anal opening is guarded by sphincter muscles that are important for control. The internal sphincter is mostly closed till the time poop enters the rectum. This prevents us from pooping involuntarily or without any control. Whereas the external sphincter allows us to control our faeces till we reach the bathroom.

In addition to this mechanism, passing of stools is controlled by the nervous system too. The nerves attached to the walls of the rectum send impulses to the brain, and then the brain causes contraction, due to which poop is finally passed out on the other hand when the pressure on the walls of the rectum is removed it sends a positive feedback to the brain and the nervous system and the sphincters relax.

This was about how and where the poop is stored and travels before it gets flushed out. Now let’s take a look at the various kinds of poops one may face during their lifetime and what they specify. 

Every Poop is Different (Poop Profile)

A normal poop should be of a firm yet soft consistency, brown in colour and a couple of inches in length. Poops may vary in colour (brown, green, yellow, red) or can also be different in consistency. Any variation from normal can be an indicator of any disease or digestive problems. The various kinds of poops are as follows.

Anyone who observes a significant change in their faeces or in the frequency of their bowel movements, however, that has no apparent reason or does not go away in a short period of time should see a doctor. Such alterations may occasionally be a sign of a health problem.

Let’s look at the various kinds of poop profiles and learn what they are usually indicative of:

1. Pellets

This type of poop is hard and separates little pellets that look like nuts or little stones and are hard and painful to pass. These little pellets are a typical indicator of constipation.

Pellets 

2. Caterpillar

It is  Log-shaped or rod-shaped with lumps which is again an indicator of constipation that shouldn’t happen very frequently. Drinking wter and taking fibrous diet can help in correcting the problem.

3. Hot Dog

It is the usual and most standardised form of poop which is Log-shaped along with some cracks on its surface which is normal to pass out.

Standard Poop 

4. Amoebas (Amoeba Like)

These are small like pellets, kind of watery and easily removable, irregularly shaped poop. It indicates that one lacks fibre in their diet.

Amoeba Poop 

5. Watery 

It is completely watery with no solid lumps. It is an indicator of diarrhoea which further is an indicator of digestive disorder.

Summary 

Pooping is a vital biological process that clears the digestive tract of waste and creates room.Poop is a wasteful product in the body that, if retained for longer than usual, can be harmful to our bodies. It is very essential to be removed after a healthy gut has absorbed every nutrient from it. Analysis of one’s poop is also essential to prevent ourselves from various problems.

For a variety of reasons, pooping may feel nice. For instance, the movement of the bowels requires the contraction and relaxation of specific muscles as well as the stimulation of specific neurons. When stimulated, some of these nerves produce delightful sensations. This was all about where poop is stored and all the related information summed up at one place. Now to check your knowledge lets look at some related frequently asked questions.

What Your Poop Says About Your Health

Intestinal peristalsis is an important part of digestion, and excrement excreted by the colon is the body’s natural way of getting rid of waste and toxins.

Normal bowel movements are a balancing act between the need to forcefully push and the urgency to go to the toilet that you can barely contain yourself.

Most of us don’t think about checking our stool in the toilet and flush it right away. But if you care about your health, you should check it regularly, as the color, texture, and consistency of feces can give clues about your inner health.

In this case, you need to pay attention to stable changes, and not to temporary anomalies that last only a day or two.

Sustained changes that last a week or more can say a lot about your health.

Contents

• 1. Excrement in the form of hard lumps
• 2. Black stools
• 3. Red or reddish feces
• 4. Green color
• 5. Blood in stool
• 6. Floating stool
• 7. Stool smells of sulfur
• 8. Loose stools
• Tips for improving bowel movements

consists of small , hard clumps of round or cylindrical shape that come out with great difficulty, this may mean that your body is either dehydrated or constipated.

Constipation is possible even with daily bowel movements, when your stool is constantly hard and comes out in lumps after intense exertion, which can lead to hemorrhoids.

What to do in this case?

Drink more water and eat foods high in both soluble and insoluble fiber .

In addition, add magnesium rich foods to your diet . Magnesium retains water in the intestines, making the stool softer and easier to pass. It also relaxes the muscles in the intestinal wall, which also helps with constipation.

2. Black stools

Newborn stools are black during the first few days after birth, but soon change to normal.

If an adult has black stool, it may be due to simply eating something black, such as eating something very dark (eg, black licorice, blueberries), or taking a specific drug or dietary supplement with iron.

But if black stool appears constantly, then this may be a sign of more serious problems, such as bleeding ulcers in the upper digestive tract or in the esophagus (from acid reflux), as well as non-carcinogenic or carcinogenic tumors . In this case, you need to visit a doctor.

3. Red or reddish stool

As with black stools, red or reddish stool is not normal and may indicate bleeding in the lower part of the intestinal tract – large intestine or rectum. The causes of bleeding can be both benign and cancerous tumors, inflammation in the colon (colitis), polyps in the colon, diverticulitis, and even hemorrhoids.

However, if you have had reddish stools for only one or two days, you have nothing to worry about, since this color could be associated with food containing red food coloring or including beets, cranberries, tomato juice or soup, gelatin or drinks Red.

Call your doctor right away if you see red stools but you haven’t eaten anything red.

4. Green color

The appearance of green stools most likely means that you have consumed too many leafy green vegetables or foods containing green food coloring, such as ice cream, ice cream, cakes, jellies and so on. The green color of the stool may also be due to some of the micronutrients present in the supplements you may be taking.

If you have green diarrhea, this means that your food passed through the intestines too quickly, and the bile did not have enough time to digest the fat, which gives the excrement a normal brown color.

Note that explosive green stool may indicate that you have infectious clostridial diarrhea caused by the bacteria Clostridium difficile (C. diff). It usually occurs after a course of antibiotics, which can kill the good bacteria that keep C. diff from growing.

5. Blood in the stool

Bright red blood in the stool is something to be taken very seriously.

Visible blood in the stool is the main sign of rectal bleeding. This blood can be bright red, maroon, or even black.

However, streaks of blood on the outside of your stool may indicate a ruptured hemorrhoid or rectal sphincter due to constipation.

Other causes of blood in the stool can be a bleeding stomach ulcer, colitis, abnormal blood vessels, inflammation of the stomach lining, anal fissures, polyps, cancer, diverticulitis, inflammatory bowel disease, or an intestinal infection.

Whenever you notice blood in your stool, you should see your doctor to rule out the possibility of a serious health problem.

6. Floating stool

If you notice that your stool is floating in the toilet without sinking to the bottom, it could be due to several reasons.

Usually floating chair is what you eat. A change in diet can lead to an increase in the amount of gas in the feces, causing buoyancy. Another common cause is poor absorption of nutrients (malabsorption). Floating stools can also indicate a gastrointestinal infection.

However, if floating stool becomes common, it may be due to inflammation of the pancreas, which reduces the body’s production of sufficient digestive enzymes. Inflammation can be caused by a food allergy or an infection that can damage the lining of the intestines.

Most causes of floating stool go away without treatment, but if the problem persists, see your doctor.

7. Stool smells of sulfur

Unusually smelling stools may indicate health problems such as malabsorptive disorder, celiac disease, Crohn’s disease, chronic pancreatitis, or cystic fibrosis (CF).

If your stool smells of sulfur or rotten eggs and you have symptoms of diarrhea, this may indicate a stomach infection due to bacteria, viruses or parasites.

8. Loose stools

If your stools are very loose, but not as much as with diarrhea, this may indicate a gluten intolerance to cereals (celiac disease).

Those with celiac disease cannot tolerate gluten, the protein found in wheat, rye and barley. Gluten contributes to the thinning of the stool, which can occur several times a day. Switching to the gluten-free diet may solve this problem.

Sometimes, if your stool has changed and become more thin and your frequency of going to the toilet has increased, this may indicate hyperthyroidism ( overactive thyroid ), a disease in which the thyroid gland produces too much thyroid hormone.

If symptoms persist, always consult a doctor.

Tips for improving bowel movements

• If you have chronic toilet problems, consult your doctor.

• Include unprocessed natural foods such as fiber-rich vegetables in your diet.

• Avoid artificial sweeteners, fructose, chemical additives, MSG (monosodium glutamate), and excess caffeine.

• Increase your gut microflora by including fermented or probiotic foods (probiotics) such as yogurt in your diet. After consulting with your doctor, you can take probiotic nutritional supplements.

• Drink enough water to keep your body well hydrated.

• Exercise daily to keep your digestive system in good health.

• Take the necessary steps to minimize chronic stress.

• If you are taking medications that cause constipation, ask your doctor to prescribe other medications.

Black stool is a symptom that may indicate some serious health conditions. The article will talk about the causes of black feces in adults and children, and the need for immediate consultation with a doctor.

Black stool is a change in the color and texture of stool that attracts the attention of a person. Doctors and health experts believe that changes in the color and consistency of stool become the basis for identifying a number of diseases. One of the changes that people can experience is black stools, which can indicate certain medical conditions.

The black chair is an excellent frame for discussion with healthcare professionals and experts. In this article, we look at the various causes that can lead to black stools using scientific and research evidence. The most common causes include consumption of certain drugs and drinks, as well as dietary and medical conditions.

Be aware that any change in stool color or texture may be a sign of serious illness. If you find that you have black stools, then you need to visit a doctor and conduct a diagnosis in order to find and treat the cause of its appearance.

Causes of black stools

Black stools in adults and children can be due to various causes. One of the most common causes is a digestive problem. For example, black stools can be a sign of bleeding from the upper parts of the digestive system, such as the stomach or esophagus.

A third cause of black stools may be related to liver disease. Chronic liver failure, cirrhosis, and acute hepatitis can cause black stools. Bowel diseases, such as intestinal inflammation, can also cause black stools.

• Digestive disorders – bleeding from the stomach or esophagus
• Medicines – contain iron or activated charcoal
• Liver disease – chronic liver failure, liver cirrhosis , acute hepatitis
• Diseases of the intestines – inflammation of the intestines

In any case, if you or your child has black stools, you should immediately consult a doctor for an examination and find out the cause of this symptom.

Bleeding in the gastrointestinal tract

Bleeding in the gastrointestinal (GI) tract can cause black stools. This can happen due to peptic ulcer of the stomach or duodenum. Bleeding can lead to the fact that the blood, entering the intestines, oxidizes and turns black.

In addition, bleeding can be caused by an intestinal infection or an ulcer in the small intestine, which can also lead to black stools.

If you have black stools, it does not mean that you are definitely experiencing bleeding in the gastrointestinal tract. However, if you notice such symptoms, you should immediately consult a doctor to find out the causes of the problem.

1. Symptoms associated with bleeding in the gastrointestinal tract:

• Black stools
• Bloody or black coffee powder in stools
• Severe abdominal pain
• Nausea and vomiting

Taking iron supplements

Iron is essential element for our body. It is involved in the creation of hemoglobin, which is essential for transporting oxygen throughout the body. An iron deficiency can lead to anemia, which causes weakness, fatigue, and poor quality of life. Iron supplements are often prescribed to restore iron levels in the blood.

Black stools when taking iron supplements are not a serious problem and are not a sign of illness. However, if the stool turns black in the absence of taking such drugs, you should consult a doctor. This may be due to bleeding in the deep parts of the gastrointestinal tract.

• Iron supplements should be taken as prescribed by your doctor.
• Before taking iron supplements, it is recommended to clarify information about the correct intake and possible side effects.
• If you develop black stools while taking iron supplements, you must remain calm and do not stop taking the supplement without consulting your doctor.

Using activated charcoal for black stools

Activated charcoal is an effective way to deal with black stools, which can be caused by a variety of causes, including bleeding in the gastrointestinal tract, taking iron, or sometimes even products that contain paint, such as ink or dyes. sweets.

It is important to note that when using activated charcoal, the correct dosage prescribed by the doctor must be observed. If the dosage is exceeded, side effects such as constipation or diarrhea may occur. In addition, the drug may interact with other drugs and reduce their effectiveness, so you should consult a specialist before use.

If you or your child has black stools, it is always worth contacting a doctor who can help identify the cause and prescribe the right treatment. The use of activated charcoal can be part of the treatment, but it should not be used without consulting a doctor.

A nutritious diet

One of the most important factors influencing intestinal health is a proper and nutritious diet. In addition, nutrition can affect the color of the stool. A common cause of black stool is the consumption of foods that contain a large amount of iron, such as buckwheat or meat.

Prebiotics have a great influence on the intestinal microflora, which also improve the color of feces. Prebiotics are found in vegetables, fruits, grain-based foods, and many other foods.

To avoid aggravating stool problems, it is necessary to reduce the intake of fats, salt and sugar. Also, you should not abuse alcohol, which has a strong effect on the intestines and can cause discoloration of the feces.

In other words, proper and healthy nutrition is the key to the health of both the intestines and the whole organism as a whole. Getting enough fruits, vegetables, grains, and protein foods will help maintain a healthy red stool color.

Abdominal pain with black stool in an adult and a child

Abdominal pain may be one of the symptoms associated with black stools in adults and children. Such pain can be of varying degrees of intensity and is characterized by different sensations: from dull and aching to sharp or stabbing. Pain can occur in different parts of the abdomen and indicate the presence of a certain pathology.

The most common cause of abdominal pain in black stool is peptic ulcer of the stomach or duodenum. This pathology is characterized by a violation of the integrity of the mucous membrane of the gastrointestinal tract, which leads to the development of ulcers and erosions. With acute penetration of peptic ulcer, severe pain in the epigastric region may occur.

Infectious diseases, allergic reactions to certain foods, and malignant tumors of the stomach can also be possible causes of abdominal pain with black stool. In this case, the pain may be accompanied by other symptoms, such as vomiting, nausea, fever and diarrhea.

• If you or your child has black stools and a stomach ache, you should see a doctor for advice and treatment.
• Do not try to self-medicate or take medications without a doctor’s recommendation, as improper treatment can lead to complications and worsening of the condition.

It is especially important to seek medical attention if abdominal pain associated with black stools is accompanied by bleeding from the rectum or other warning signs.

Violation of the microflora of the gastrointestinal tract

The gastrointestinal tract (gastrointestinal tract) is a complex system consisting of many different organs that perform their own unique functions. One of the key problems that can occur in the gastrointestinal tract is a violation of the microflora.

The microflora of the gastrointestinal tract is a huge number of different microorganisms that are in harmonious balance inside the human body. If this balance is disturbed, then unpleasant consequences can occur – one of which is a change in the color of the feces.

• Normal microflora of the gastrointestinal tract helps to reduce the risk of intestinal diseases and allergies
• One of the reasons for the violation of the microflora may be malnutrition (the strengthening of the microbial population in the gastrointestinal tract occurs due to the proteins, fats and carbohydrates that we consume)
• Another factor in the violation of the microflora of the gastrointestinal tract can become antibiotics that destroy both “bad” and “good” bacteria.

To prevent disruption of the gastrointestinal microflora, it is important to maintain a balanced diet and use antibiotics correctly under medical supervision. If you have unusual symptoms, including black stools, be sure to seek the help of a specialist – only he can make an accurate diagnosis and suggest the most effective treatment.

Stomach fullness

Black stools may be the result of stomach fullness, especially if the cause is edible food during festive occasions. This is due to the large amount of food consumed, which cannot be properly digested in the intestines and therefore passes through it with more intensive processing, which in turn leads to a black coloring of the stool.

Also, full stomach can be caused by diseases such as reflux disease. In this case, eating a lot of fatty or simply heavy foods can lead to full stomach and black stools.

In order to avoid black stool, it is recommended to reduce the amount of food consumed and choose healthier food supplements.

Food Tolerance

Black stools may occur if the body cannot tolerate certain foods. Some people may be sensitive to gluten, lactose, or fructose, which can cause digestive problems. If the body cannot properly digest these foods, they can cause stool discoloration and other nutritional symptoms.

If you or your child has an allergy to a food, this too can cause black stool as a result of a food reaction. Some other allergic reactions can also cause black colored stools.

It is important to watch what you eat and find out what foods can cause you or your child to have digestive problems. If you notice black stools as a result of consuming certain foods, then you should avoid them in the future or reduce the number of portions consumed.

• Foods that can cause discoloration of stool:
  • Foods containing gluten (bread, pasta, biscuits)
  • Dairy products (milk, cheese)
  • Fruits (apples, pears, grapes)
  • Iron supplements (vitamins) , additives )

If you are not sure what is the problematic product, you should consult a doctor or nutritionist for advice. They can run tests and give advice on dietary changes to avoid digestive problems and black stools.

Causes of black stools with certain medications

Drug therapy with can lead to various side effects, including discoloration of stools. Some medications, especially those containing iron, can cause black stools. This is because iron is oxidized during digestion and excreted along with waste through the intestines.

Don’t panic. However, if you suspect that black stool is due to medication, you should check with your healthcare provider to make sure it is not related to a more serious problem.

It should also be noted, that not only drugs can cause black stools. It is important to pay attention to other symptoms such as abdominal pain, fatigue, weight loss, bleeding, or urinary problems.

Some medications that can cause stool discoloration include iron supplements such as ferrous sulfate, multivitamins, anti-ischemic medications, some antibiotics such as amoxicillin and augmentin, and some medications used to treat gastroesophageal reflux (GERD) and peptic ulcer.

If you notice black stools while taking medication, be sure to contact your doctor and ask if you need to change medications or doses to avoid this effect.

Chemical poisoning

Black stool may be due to chemical poisoning. Chemicals such as heavy metals, chlorine, mercury, arsenic and other poisons can cause this reaction. They can enter the body through the mouth, skin or respiratory tract.

Chemical poisoning can have serious consequences for human health. If you suspect such poisoning, you should consult a doctor immediately. In case of poisoning with poisons, urgent treatment should be carried out immediately.

• Chemical poisoning can be prevented by following the safety rules when working with chemicals.
• Personal protective equipment such as masks and gloves must be worn.
• The storage and disposal of chemicals must also be observed.

In case of chemical poisoning, measures must be taken immediately. It is important to remember that self-medication in this situation can be hazardous to health.

Association of black feces with malignant tumors of the gastrointestinal tract

Black feces may be a sign of malignant tumors of the gastrointestinal tract. One of the causes of black feces in adults and children is bloody bleeding in the gastrointestinal tract.

This may be due to conditions such as gastric or duodenal ulcers, chronic gastritis, polyps, colitis, stomach or colon cancer.

If you notice black stools in yourself or in a child, it is urgent to see a doctor for an examination of the gastrointestinal tract, because the sooner the tumors are identified and treated, the higher the chances of a complete cure.

Black stools can also be caused by medications containing iron, activated charcoal, or food pigments.

However, one should not ignore the appearance of black feces and find out the cause of its occurrence in order to start treatment in a timely manner and prevent negative consequences.

Q&A:

What could be the causes of black feces in an adult?

Black stools in adults can be due to a variety of reasons, such as high iron intake, charcoal preparations, or bleeding in the gastrointestinal tract. Black stools are also possible due to certain medications, such as aspirin or bismuth-based medications.

What does black stool mean in a child and what could be its causes?

Black stools in a baby can be caused by a variety of reasons, such as eating foods high in iron, bleeding in the gastrointestinal tract, or taking iron-based medications. Also, black feces in a child may be the result of the use of products containing activated charcoal, for example, to treat poisoning.

Is black stool a sign of dangerous bowel disease?

Black stools can be a sign of dangerous bowel diseases such as stomach or duodenal ulcers, intestinal infarction, bowel or stomach cancer.
