The Role of Liver Enzymes in Body Function

Liver enzymes are crucial proteins produced by the liver that play a vital role in various bodily functions. These enzymes help the body fight infections, create coagulation proteins for blood clotting, break down food, and process toxins. Understanding the function of liver enzymes is essential for comprehending their significance in overall health.

Key Liver Enzymes and Their Functions

• Aspartate transaminase (AST)
• Alkaline phosphatase (ALP)
• Alanine transaminase (ALT)
• Gamma-glutamyl transferase (GGT)

Each of these enzymes plays a specific role in liver function and can provide valuable insights into liver health when measured in blood tests.

Measuring Liver Enzyme Levels: The Liver Panel Test

A liver panel test is a blood test that measures the levels of various liver enzymes in the bloodstream. Healthcare professionals may order this test as part of routine blood work, to monitor patients at risk for liver disease, or as a diagnostic tool for those experiencing symptoms of liver damage or disease.

When is a Liver Panel Test Necessary?

Doctors may recommend a liver panel test in several situations:

• During routine health check-ups
• For patients with a family history of liver disease
• When monitoring individuals with known liver conditions
• If symptoms of liver problems are present

The test is a simple blood draw that typically doesn’t require special preparation, although fasting for 12 to 24 hours may be recommended in some cases.

Causes of Fluctuating Liver Enzyme Levels

Changes in liver enzyme levels can occur due to various factors, ranging from temporary causes to more serious underlying conditions. Understanding these causes is crucial for proper diagnosis and treatment.

Temporary Causes of Elevated Liver Enzymes

Several factors can lead to temporary increases in liver enzyme levels:

• Hormonal changes during menstrual cycles or pregnancy
• Certain medications, including acetaminophen and some antibiotics
• Herbal supplements like iron, vitamin A, comfrey, and chaparral
• Heavy alcohol consumption

In most cases, enzyme levels return to normal within 2 to 4 weeks without treatment when these temporary factors are addressed.

Chronic Causes of Elevated Liver Enzymes

More serious conditions that can lead to persistently high liver enzyme levels include:

• Fatty liver disease
• Hemochromatosis
• Various types of hepatitis
• Cirrhosis
• Liver cancer
• Hemolysis
• Thyroid disease
• Metabolic syndrome

These conditions often require medical intervention and long-term management to address the underlying cause of elevated liver enzymes.

Interpreting Liver Enzyme Test Results

Understanding liver enzyme test results is crucial for assessing liver health. While the exact thresholds for normal and elevated levels can vary based on factors such as age, gender, and the specific lab’s reference ranges, there are general guidelines for interpreting results.

Normal Ranges for Liver Enzymes

Typical ranges for liver enzymes include:

• AST: under 36 U/L
• ALP: between 20 and 140 U/L
• ALT: under 25 U/L for women or under 33 U/L for men
• GGT: between 5 and 40 U/L

It’s important to note that these ranges can vary slightly between laboratories and should be interpreted in the context of an individual’s overall health profile.

Additional Liver Function Markers

In addition to enzyme levels, a liver function test may also measure:

• Albumin: between 35 and 50 U/L
• Bilirubin: between 0.1 and 1.2 mg/dl

While not enzymes, these chemicals are also produced by the liver and provide valuable information about liver function.

Symptoms Associated with Elevated Liver Enzymes

Elevated liver enzymes often don’t cause noticeable symptoms, especially in the early stages. However, as liver damage progresses, individuals may experience various signs and symptoms.

Common Symptoms of Liver Problems

Some symptoms that may indicate liver issues include:

• Fatigue and weakness
• Abdominal pain or swelling
• Jaundice (yellowing of the skin and eyes)
• Dark urine
• Pale stools
• Nausea or loss of appetite
• Itchy skin

If you experience these symptoms, especially in combination with risk factors for liver disease, it’s important to consult a healthcare professional for evaluation.

Treatment Options for High Liver Enzyme Levels

The treatment approach for elevated liver enzymes depends on the underlying cause. In many cases, addressing temporary factors can lead to a natural return to normal levels within about a month.

Lifestyle Changes and Medication Adjustments

For temporary elevations, treatment may involve:

• Switching medications or adjusting dosages
• Discontinuing certain supplements
• Reducing alcohol consumption
• Adopting a healthier diet and exercise routine

Medical Interventions for Chronic Conditions

For more serious underlying conditions, treatment may include:

• Additional diagnostic tests (imaging, blood tests, liver biopsy)
• Medication to manage specific liver conditions
• Lifestyle modifications to support liver health
• Regular monitoring and follow-up care

The specific treatment plan will be tailored to the individual’s condition and overall health status.

Preventing Liver Enzyme Elevations and Maintaining Liver Health

While some causes of elevated liver enzymes are beyond an individual’s control, there are several steps one can take to promote liver health and potentially prevent enzyme elevations.

Lifestyle Habits for Optimal Liver Function

To support liver health, consider adopting the following habits:

• Limit alcohol consumption
• Maintain a healthy weight
• Exercise regularly
• Eat a balanced diet rich in fruits, vegetables, and whole grains
• Avoid unnecessary medications and supplements
• Practice safe sex and avoid sharing needles to prevent hepatitis
• Get vaccinated against hepatitis A and B

By incorporating these practices into your daily routine, you can help protect your liver and maintain healthy enzyme levels.

The Importance of Regular Liver Function Monitoring

Regular monitoring of liver function is crucial for early detection and management of potential liver issues. This is particularly important for individuals with risk factors for liver disease or those taking medications that may affect liver function.

Who Should Undergo Regular Liver Function Tests?

Individuals who may benefit from regular liver function monitoring include:

• Those with a family history of liver disease
• People with chronic conditions such as diabetes or obesity
• Individuals taking medications known to affect liver function
• People with a history of alcohol abuse
• Those exposed to hepatitis or other liver-damaging substances

Discuss with your healthcare provider to determine the appropriate frequency of liver function tests based on your individual risk factors and health status.

Understanding liver enzyme levels and their significance is crucial for maintaining overall health. By recognizing the causes of elevated liver enzymes, interpreting test results accurately, and taking appropriate preventive measures, individuals can play an active role in protecting their liver health. Regular check-ups and open communication with healthcare providers are key to managing liver function effectively and addressing any concerns promptly. Remember, early detection and intervention can make a significant difference in preventing and managing liver-related health issues.

What To Do About Fluctuating Liver Enzyme Levels

Liver enzymes are proteins the liver produces. The amount of these proteins in your blood is a good indication of your liver’s overall health. But elevated liver enzyme levels do not always mean serious liver damage or disease.

Sometimes, factors such as hormonal changes or reactions to medications can cause temporarily elevated liver enzyme levels. Elevated levels caused by these factors will generally return to normal in about 2 to 4 weeks without treatment.

Your liver makes proteins called liver enzymes that help your body perform necessary functions. For instance, liver enzymes help your body:

• fight infections
• make coagulation proteins that are necessary for blood clotting
• break down the food you eat
• break down toxins

Your liver makes several liver enzymes, including:

• Aspartate transaminase (AST)
• Alkaline phosphatase (ALP)
• Alanine transaminase (ALT)
• Gamma-glutamyl transferase (GGT)

These liver enzyme levels are a good indicator of how well your liver is functioning. A liver panel test checks liver enzyme levels in your blood.

A healthcare professional might order this test as part of routine blood work, as a way to monitor you if you’re at risk for liver disease, or as a diagnostic test if you have symptoms of liver disease or liver damage.

There are many reasons liver enzyme levels can change. Some causes are temporary and will resolve on their own. Other causes are more serious and will require medical treatment.

Temporary causes of changes in liver enzyme levels include:

• Hormones: Fluctuations in your liver levels can occur during your menstrual cycle and pregnancy.
• Certain medications: Some medications, including acetaminophen, antibiotics, and some cholesterol-lowering medications, can elevate your liver enzyme levels.
• Herbal supplements: Supplements such as iron, vitamin A, comfrey, and chaparral can elevate liver enzyme levels.
• Alcohol: Heavy drinking can raise your liver enzyme levels.

Causes of elevated liver enzyme levels that are more likely to be chronic include:

• Fatty liver disease: Heavy alcohol use, obesity, and a range of other factors can cause fatty liver disease. No matter the cause, fatty liver disease raises your liver enzyme levels.
• Hemochromatosis: Hemochromatosis is a rare condition that occurs when your body builds up too much iron. Elevated liver enzyme levels can be a symptom of the condition.
• All types of hepatitis: Any type of hepatitis, including hepatitis A, hepatitis B, hepatitis C, autoimmune hepatitis, and alcoholic hepatitis, causes liver inflammation and elevated liver enzymes.
• Cirrhosis: Cirrhosis is chronic liver damage. This damage causes elevated levels of liver enzymes.
• Liver cancer: Cancer that impacts your liver will also affect your liver enzyme levels.
• Hemolysis: Hemolysis is a type of anemia that occurs when your red blood cells are destroyed. It’s sometimes seen with alcohol-related liver diseases, and it can cause changes to liver enzyme levels.
• Thyroid disease: Hyperthyroidism can sometimes cause high levels of liver enzymes.
• Metabolic syndrome: Metabolic syndrome is a term that refers to a group of conditions that raise your risk of diabetes, heart disease, and stroke. These conditions include high blood pressure, high cholesterol, high blood sugar, and carrying excess weight around your midsection. People with metabolic syndrome may also have elevated liver levels.

The exact threshold for what is considered an elevated level or a typical level depends on your age, gender, health goals, and the values used by the specific lab. You can see some standard thresholds below.

• AST: under 36 U/L
• ALP: between 20 and 140 U/L
• ALT: under 25 U/L for women or under 33 U/L for men
• GGT: between 5 and 40 U/L

A liver function test might also measure:

• Albumin: between 35 and 50 U/L
• Bilirubin: between 0. 1 and 1.2 mg/dl

These values are not enzymes, but they’re also important chemicals made by your liver.

A liver function test is a standard blood draw. It can be done during a regular office visit. You don’t generally need any special preparation before a liver function test, although a doctor might ask you to fast for 12 to 24 hours before the blood draw. You can read more about liver function tests here.

The treatment for elevated liver enzymes depends on the cause. In many cases, liver enzyme levels return to normal on their own within about a month. You might need to switch medications, stop taking a supplement, or cut back on drinking if you drink, but you will not need a treatment plan.

In other cases, your doctor might need to treat the condition that’s raising your liver enzyme levels. They might order more tests, such as imaging tests, to get a better look at your liver or blood tests. They might also order a liver biopsy. Depending on your results, you might be referred to a specialist. Treatment will depend on your final diagnosis.

If you’re concerned your liver enzyme levels might be elevated, you might consider making some lifestyle changes at home, such as:

• reducing or eliminating alcohol from your diet
• being cautious about the medications and supplements you take
• staying active, including exercising regularly
• trying to add liver-friendly foods to your diet
• maintaining a moderate weight

Liver enzyme levels are an important indication of your liver’s health. When your enzyme levels are too high, it can be a symptom of liver damage or disease.

Some causes of elevated liver levels, such as hormonal changes or certain medications, are temporary and might resolve without treatment. Other causes are more serious and can include conditions such as cirrhosis, hepatitis C, and liver cancer.

Treatment for high liver enzyme levels depends on the cause.

8 Common Reasons for a High Liver Enzyme Count – ActiveBeat

• A high liver enzyme count often means there is inflammation or damage to cells in your liver.
• Individuals often don’t experience symptoms until the liver is damaged.
• Treatment will depend on what is causing your high liver enzyme count so it’s important to know all the possible causes.

So, your doctor has told you that you have a high liver enzyme count…now what? It could be associated with a disease or another health problem, but a doctor will be the one to assess the symptoms and rule out the possible causes.

In some cases, further tests will be needed to pinpoint the exact reason behind the elevated liver enzyme count. It can be something relatively minor that can easily be adjusted, or it can be something more serious that requires further medical supervision.

Here are eight possible reasons for a high liver enzyme count plus symptoms to watch for and how it’s treated.

Pain Relievers

Over-the-counter (OTC) pain relievers can cause your liver enzyme count to be high. LiveStrong says some types can stress your liver at the recommended dose while others can stress your liver at nearly any dose.

Aside from OTC pain relievers, prescription drugs for cholesterol can also be the culprit. If your liver enzyme count is high be sure to discuss any prescription and OTC medications you are taking with your doctor.

Heart Failure

This is a more concerning cause of a high liver enzyme count because it means your heart isn’t pumping blood the way it should be, notes the Mayo Clinic. Certain conditions, such as coronary artery disease, can stress the heart and make it too weak to pump efficiently.

“Not all conditions that lead to heart failure can be reversed, but treatments can improve the signs and symptoms of heart failure and help you live longer,” adds the source. While the doctor may be able to trace the cause of your heart problems (such as congestive heart failure), elevated liver enzymes aren’t always traced to the heart.

Non-Alcoholic Fatty Liver Disease

The Cleveland Clinic says non-alcoholic fatty liver disease is one of the most common causes of a high liver enzyme count, which can range in severity. It represents the storage of extra fat in the liver. The disease is “mostly silent,” which is why it is often discovered incidentally through routine tests for another health problem (such as blood tests as part of your yearly physical).

Although the disease often sits in the background as a benign condition until it’s discovered, it can be serious if it’s in the form of nonalcoholic steatohepatitis (NASH). “NASH can progress to fibrosis and lead to end-stage liver disease,” adds the source.

Hepatitis

MedicineNet explains testing for liver enzyme counts is one of three ways that doctors evaluate patients with hepatitis (or inflammation of the liver). “If the liver is injured (as in viral hepatitis), the liver cells spill the enzymes into the blood, raising the enzyme levels in the blood and signaling that the liver is damaged,” it notes.

Hepatitis is commonly caused by a viral infection, and there’s an autoimmune form of the disease that causes your own body’s immune system to attack your otherwise healthy liver. There are a number of types of hepatitis, each with its own possible causes.

Alcoholic Liver Disease

The National Institute on Alcohol Abuse and Alcoholism says that a history of heavy drinking may be responsible for your high liver enzyme count. However, alcoholic liver disease (ALD) can sometimes be a challenge for doctors to diagnose because patients often downplay their alcohol consumption, notes the source.

A medical diagnosis then relies on lab tests of three specific liver enzymes: gamma-glutamyltransferase (GGT), aspartate aminotransferase (AST), and alanine aminotransferase (ALT). Doctors will look for AST levels that are significantly higher than ALT levels.

The source explains that studies have shown that in about 80-percent of cases of ALD, the AST level is more than double that of the ALT level. GGT is another indicator of excessive drinking, “but GGT is present in many organs and is increased by other drugs as well,” it adds.

Celiac Disease

This is a condition where the digestive system is sensitive to gluten, which is found in grains, such as wheat, rye, and barley, causing a host of unpleasant symptoms. It can also cause your liver enzyme count to be out of whack, notes the University of Chicago Medicine.

The source also points out that your liver enzyme levels should go back to normal soon after cutting out gluten products (from a month to a year). If they don’t, then you may have another problem on your hands. Doctors may have to perform a liver biopsy if a change in your diet (such as a gluten-free diet) doesn’t cause the enzyme levels to decrease and no other cause is obvious.

Thyroid Problems

Hypothyroidism (or a low-functioning thyroid gland) is when this gland doesn’t produce enough thyroid hormones, which are responsible for a number of functions in your body (including liver function), notes Everyday Health.

The liver and thyroid are pretty closely connected. “Not only does the liver play a role in the chemical process that develops thyroid hormones but also untreated hypothyroidism can cause problems in liver function over time,” it explains. The doctor may order a liver panel test to look for things such as irregular GGT liver enzyme levels to determine a course of treatment.

Wilson’s Disease

Wilson’s disease could also be the cause of elevated liver enzymes, specifically ALT and AST. This is a “rare inherited disorder that causes copper to accumulate in your liver, brain and other vital organs,” explains the Mayo Clinic.

While copper is an essential mineral that plays a role in developing healthy bones and nerves, individuals with Wilson’s disease can’t eliminate copper properly. This causes it to accumulate “to a life-threatening level,” says the source. Luckily, if caught early, the disease is treatable but if left untreated, it can be fatal.

Risk Factors

Certain factors may increase your risk for elevated liver enzymes. For starters, the Cleveland Clinic says alcohol abuse and taking certain medications or vitamin supplements may increase your risk.

Having diabetes or a family history of liver disease may also increase your risk. As can having hepatitis or exposure to hepatitis, says the source. If you’re worried about your risk, talk to your doctor if you should be screened for high liver enzymes.

Common Symptoms of Elevated Liver Enzymes

Unfortunately, many people with elevated liver enzymes don’t develop symptoms, says the Cleveland Clinic. However, if the high levels cause liver damage, you may develop noticeable symptoms.

Some symptoms of liver damage to be on the lookout for include stomach pain, fatigue, jaundice (yellowing of the skin and whites of the eyes), and itching. You may also have dark urine, light-colored stools, loss of appetite, nausea, and vomiting. If you develop any of these symptoms, contact your doctor.

How Is It Treated?

Treatment will depend on what is causing your high liver enzyme count. For example, if non-alcoholic fatty liver disease is causing your high levels, your doctor may recommend dietary changes and exercise.

If liver enzymes remain high after initial treatment your doctor may require more tests such as blood tests, ultrasound, computed tomography (CT) scan, or magnetic resonance imaging (MRI) scan. You may also be referred to a liver specialist, known as a hepatologist.

Can It Be Prevented?

While not all conditions that cause high liver enzymes can be prevented, there are steps you can take to help keep your liver healthy, says the Cleveland Clinic. For starters, you can avoid alcohol, or at the very least drink in moderation.

The source says you can also protect your liver by managing a healthy weight, eating a healthy diet, and exercising regularly. If you have diabetes, it’s important to manage your blood sugar levels. Furthermore, to protect yourself against hepatitis you can get the hepatitis A and B vaccine (if you don’t have it already). Finally, the source says you should inform your doctor about any medications, herbs, and supplements you take to ensure it’s safe for your liver.

When the liver goes wrong: a gastroenterologist named 4 common reasons why ALT and AST are elevated in the blood

• Health

However, the growth of these main “liver” markers in the blood test does not always indicate problems.

A biochemical blood test is considered one of the main ways to find out if the liver copes with the load of “wrong” nutrition, alcohol, and medication. This will be told by such indicators in the analysis as ALT (alanine aminotransferase) and AST (aspartate aminotransferase) – these liver enzymes are among the first to respond to malfunctions of the organ.

– If there is an increase in both ALT and AST, this means that the liver cells are destroyed and the enzymes from them enter the blood. (…) An increase in AST and ALT means that an inflammatory process is taking place in the liver and its cells are being destroyed. If the indicators are above the norm, you need to contact a gastroenterologist, – gastroenterologist Maria Lopatina wrote in her telegram channel, adding that the upper limits of the norm may differ in different laboratories and one must focus on those established where the analysis was taken.

The doctor named the 4 most common causes of increased liver values.

Chronic viral hepatitis

With an increase in ALT and AST in the blood, viral hepatitis B and C are always excluded first. This is very important, as they can be asymptomatic, while destroying the liver. Mandatory tests: HBsAg – hepatitis B and Anti-HCV – hepatitis C.

Non-alcoholic fatty liver disease

When fatty liver cells destroy them, ALT and AST in the blood rise and steatohepatitis develops.

Fatty liver disease is suspected if:

• Waist circumference ≥94/≥80 cm in men/women;

• Blood pressure 130/85 mmHg And more, or the person is taking antihypertensive drugs;

• Fasting glucose level of 5.6 mmol/l or more, or the person is taking hypoglycemic drugs;

• Serum triglycerides more than 1.7 mmol/l;

• High-density lipoprotein (HDL) level less than 1.0/1.3 mmol/l in men/women.

Drug-induced liver injury

All drugs that we take by mouth pass through the liver. The more drugs we take, the more likely it is to be damaged. This group includes both herbal preparations and dietary supplements. Liver damage can occur immediately or after several weeks.

Alcohol

According to Russian clinical guidelines, a safe dose for the liver in women is 20 grams of ethanol per day, for men – 40 grams. Regular excess of this dose leads to the development of alcoholic hepatitis and an increase in ALT and AST.

Determining the ethanol content in 100 ml of a drink is very simple: the percentage of alcohol in the drink must be multiplied by 0.8. Thus, 100 ml of 40% vodka contains 40×0.8=32 grams of ethanol, and 100 ml of 12% wine contains 12×0.8=9.6 grams of ethanol.

The doctor specifies that there are other reasons for the increase in ALT and AST in the blood, but these four are the most common.

When an increase in the indicator is not a cause for alarm

It happens that an increase in the level of “liver” indicators may not be associated with a problem in the work of our main “filter”. According to gastroenterologist Maria Lopatina, this may be the case if only the AST index is elevated.

– AST is found not only in the liver, but also in the heart, muscles, kidneys, brain and pancreas. If AST levels are elevated and ALT is normal, causes that are not related to damage to liver cells should be ruled out. For example, active training for all muscle groups, the doctor clarifies.

But if the liver values ​​were below normal in the blood test, in most cases this is not a cause for serious concern. According to the gastroenterologist, a decrease in their level can occur during pregnancy, starvation and a reduced content of vitamin B6.

Signs of liver problems that can be seen in the mirror

According to doctors, the liver does not hurt in the usual sense of the word, especially at first – specific symptoms of the disease appear when things have gone too far. As the head of the MIBS outpatient department, gastroenterologist Iyri Alaya said, liver diseases are often accompanied by various digestive disorders:

• Increased flatulence;

• Feeling of fullness in the stomach;

• Rapid satiety after eating;

• Loss of appetite;

• Dryness and bitterness in the mouth;

• Attacks of nausea and vomiting;

• Constipation or diarrhoea.

And the most famous sign of liver problems is yellowness of the skin, mucous membranes and sclera, which indicates an increase in the level of bilirubin (bile pigment) in the blood.

Alanine aminotransferase (ALT) is one of the indicators of a biochemical blood test that can signal liver damage. Elevated ALT levels can be indicative of a variety of diseases and conditions. The main thing is not to ignore this symptom and consult a doctor immediately.

Elevated blood levels of ALT can be caused by a variety of causes, including viral hepatitis, alcoholic and non-alcoholic fatty liver disease, drug poisoning, biliary obstruction, infectious diseases, and others. This indicator can also increase with prolonged physical exertion on the body, as well as during pregnancy.

In order to establish an accurate diagnosis, a comprehensive examination is required. In addition to a biochemical blood test for ALT, ultrasound and X-ray examinations of the abdominal organs, blood tests for other indicators, etc. can also be performed.

It is important to remember that spontaneous treatment can cause great harm to health. Be sure to contact only qualified doctors and follow all doctor’s prescriptions.

Elevated blood ALT

ALT (alanine aminotransferase) is an enzyme found in liver cells. When liver cells are damaged or destroyed, ALT is released into the bloodstream, causing an increase in blood levels of the enzyme.

To diagnose an elevated ALT level in the blood, it is necessary to conduct a blood test for biochemical analysis. In addition, additional tests, such as liver ultrasound or computed tomography, may be needed to determine the cause of elevated ALT levels.

• To reduce the level of ALT, you need to see a doctor and determine the cause of the change in level.
• Certain measures, such as avoiding alcohol, eating healthy, and exercising, can help lower your ALT levels.
• Treatment of liver diseases is based on the cause of the disease.

ALT: what it is and how it works

ALT is an enzyme that converts alanine to pyroglutamate. ALT is found within liver cells, and to a lesser extent in the heart, muscles, and other organs.

It is important to understand that ALT cannot cross cell membranes. If the level of ALT is elevated, this may indicate the destruction of the cells that contain this enzyme.

ALT is used in medical diagnostics as an indicator of damage to the liver and other organs. Elevated blood levels of ALT can indicate various diseases such as viral hepatitis, liver cirrhosis, liver cancer, as well as drug toxicity and other health conditions.

1. ALT is an important indicator of the health of the liver and other organs
2. Elevated levels of ALT can indicate various diseases
3. It is important to identify the cause of elevated levels of ALT in the blood for proper diagnosis and treatment

Functions of ALT in the body

ALT (alanine aminotransfer aza) is an enzyme found in body tissues, especially in the liver and heart. There are several functions of ALT in the body. One of its main functions is participation in the metabolism of protein compounds, including amino acids.

In addition, ALT plays a key role in animal metabolism. It helps to remove excess ammonia, which is toxic to the body.

Changes in the level of ALT in the blood may indicate abnormalities in the functioning of the liver, heart and other organs.

Causes of elevated ALT levels

Alanine aminotransferase (ALT) is an enzyme found in the cells of the liver, heart, muscles and other organs. Its level in the blood is an indisputable marker of diseases of certain organs and tissues. Consider the main reasons for the increase in the level of ALT in the blood.

• Liver diseases . Elevated ALT levels can be associated with various liver diseases such as hepatitis, cirrhosis, jaundice, and others. In these cases, an increase in ALT levels may be one of the first signs of the disease.
• Alcoholism . Heavy drinking can lead to liver damage and elevated ALT levels.
• Muscle injury . Muscle injury can lead to elevated ALT levels. Also, exercises that cause intense stress on the muscles can lead to an increase in ALT levels for a short time.
• Medicines . Certain medications, such as aspirin, antibiotics, steroids, and others, can raise blood levels of ALT.

Remember that elevated ALT is not a disease in itself, but only a marker. Diagnosis and identification of the causes of elevated levels of ALT in the blood requires a visit to a doctor and further examination.

Diseases that cause elevated levels of ALT in the blood

Hepatitis

An increase in the level of ALT in the blood is often associated with hepatitis – viral or alcoholic. Hepatitis is an inflammatory reaction of the liver that can lead to elevated levels of ALT in the blood. With viral hepatitis, ALT can increase by several tens of times.

Cirrhosis of the liver

Cirrhosis of the liver is a chronic disease in which healthy liver tissue is replaced by scarring, which can lead to decreased liver function. A high level of ALT in the blood can be one of the signs of cirrhosis of the liver.

Cholelithiasis

In gallstone disease, stones form in the gallbladder or bile ducts, which can lead to inflammation of the liver. ALT levels may be elevated in acute or chronic inflammation of the liver associated with gallstone disease.

Aminotransferase dystrophy (ATD)

Aminotransferase dystrophy is a genetic disease that causes an increase in the level of ALT in the blood. This is due to a violation of the transfer of the amino acid alanine between cells.

Other diseases

Elevated levels of ALT may also be associated with other liver diseases such as hepatosis (changes in the structure of the liver), liver cancer or even heart failure.

Some diseases associated with an increase in the level of ALT Disease Description

Symptoms of elevated blood levels of ALT

Elevated levels of ALT in the blood can be a symptom of various diseases and organ dysfunctions.

An increased amount of ALT may indicate the presence of viral hepatitis, cirrhosis of the liver, liver cancer, alcohol and drug intoxication, diseases of the liver, bile ducts and biliary tract. Elevated ALT levels can also be observed in people with diabetes and obesity.

If you have symptoms of elevated ALT levels in the blood, it is important to immediately consult a doctor and undergo a comprehensive examination in order to identify the cause of this condition and begin timely treatment.

Diagnosis of elevated ALT levels

Diagnosis of elevated blood ALT levels begins with a complete blood count, which is often performed during routine check-ups. If the ALT level exceeds the norm, then the doctor may prescribe additional studies.

To confirm the diagnosis and determine the cause of elevated ALT levels, more accurate tests, such as biochemical tests of blood, urine and feces, as well as ultrasound of the liver and gallbladder, may be prescribed.

• Blood chemistry tests can help determine specific ALT levels as well as other indicators associated with liver disease;
• Ultrasound examination of the liver and gallbladder allows you to determine possible changes in these organs and study their structure;
• Urine and feces analysis helps to find out which metabolic products are excreted from the body;

Depending on symptoms and other factors, your doctor may order additional tests and procedures to identify the cause of your high ALT levels. The results of all these studies will help to make an accurate diagnosis and prescribe the right treatment.

ALT Tests: Preparation and Procedure

ALT testing requires preparation. Within 12 hours before blood sampling, it is recommended not to eat, and also to exclude the intake of alcohol, fatty and fried foods, and smoking. This will help avoid distorting the analysis results.

ALT results are usually available 1-2 days after blood sampling. With elevated ALT levels, additional diagnostics may be required to identify the cause of this phenomenon, but only a doctor can determine the need for such a study.

ALT blood levels

ALT (alanine aminotransferase) is an enzyme produced in the liver cells and other body tissues. The normal level of ALT in the blood in adult men does not exceed 45 units per liter, in women – no more than 34 units per liter.

In children and adolescents, normal ALT levels may vary by age. So, in children under the age of 9 years, the normal level of ALT is no more than 50 units per liter, in adolescents aged 9 to 12 years – no more than 45 units per liter, and in boys and girls aged 12 to 18 years – no more than 55 units per liter.
