Common Types of Liver Problems and Their Underlying Causes

The liver plays a crucial role in maintaining overall health by performing various essential functions. It processes nutrients, filters toxins, and aids in energy production. When liver function is compromised, it can have far-reaching effects on the entire body. Understanding the diverse causes of liver problems is vital for early detection and proper management.

Viral Hepatitis: A Major Culprit in Liver Inflammation

Viral hepatitis is one of the most prevalent causes of liver inflammation. There are several types of hepatitis viruses, each with distinct characteristics:

• Hepatitis A: Typically contracted through contaminated food or water
• Hepatitis B: Transmitted through bodily fluids, often via unprotected sex or shared needles
• Hepatitis C: Spread through infected blood, commonly associated with intravenous drug use or occupational exposure in healthcare settings

Can hepatitis resolve on its own? In some cases, such as hepatitis A, the infection may clear without long-term consequences. However, chronic forms of hepatitis B and C can lead to severe liver damage if left untreated.

Autoimmune Disorders Affecting the Liver

The immune system, designed to protect the body from harmful invaders, can sometimes malfunction and attack the liver. This results in autoimmune liver disorders, which include:

• Autoimmune hepatitis: More common in females, causing liver inflammation
• Primary biliary cholangitis: Affects the bile ducts, leading to bile buildup and liver scarring
• Primary sclerosing cholangitis: Causes scarring and potential blockage of bile ducts

Why do autoimmune liver disorders occur more frequently in certain populations? While the exact reasons are not fully understood, genetic predisposition and environmental factors likely play a role in the development of these conditions.

Liver Cancer: Primary and Secondary Forms

Liver cancer can originate within the liver (primary) or spread from other parts of the body (secondary). Understanding the different types of liver cancer is crucial for proper diagnosis and treatment:

1. Hepatocellular carcinoma: The most common form of primary liver cancer
2. Bile duct cancer: A rare cancer affecting the bile ducts
3. Liver cell adenoma: A benign tumor with a small risk of malignant transformation

Are there risk factors that increase the likelihood of developing liver cancer? Yes, chronic hepatitis infections, excessive alcohol consumption, and certain genetic conditions can elevate the risk of liver cancer.

Inherited Liver Disorders: Genetic Factors at Play

Some liver conditions are passed down through families due to genetic mutations. These inherited disorders can have significant impacts on liver function and overall health:

• Hemochromatosis: Causes excessive iron absorption and storage
• Hyperoxaluria: Results in elevated oxalate levels, affecting both liver and kidneys
• Wilson’s disease: Leads to copper accumulation in various organs, including the liver
• Alpha-1 antitrypsin deficiency: Involves the production of a faulty protein by the liver

How are inherited liver disorders diagnosed? Genetic testing, along with clinical symptoms and family history, plays a crucial role in identifying these conditions.

Lifestyle-Related Liver Conditions

Certain lifestyle choices and environmental factors can contribute to the development of liver problems:

• Alcohol abuse: A leading cause of cirrhosis
• Drug-induced liver injury: Overdose of medications like acetaminophen can harm the liver
• Nonalcoholic fatty liver disease (NAFLD): Excessive fat accumulation in the liver, often associated with obesity and metabolic syndrome

Is it possible to reverse lifestyle-related liver damage? In many cases, early intervention and lifestyle modifications can significantly improve liver health and potentially reverse some forms of damage.

The Importance of Liver Function Tests in Diagnosis

Liver function tests play a crucial role in assessing liver health and detecting potential problems. One key component of these tests is the measurement of alanine aminotransferase (ALT) levels in the blood.

Understanding ALT Blood Tests

ALT is an enzyme primarily found in liver cells. When liver cells are damaged or die, ALT is released into the bloodstream. Elevated ALT levels can indicate liver inflammation or damage.

What is considered a normal ALT level? Generally, ALT levels below 50 units per liter (U/L) are considered normal for men, while levels below 35 U/L are normal for women. However, these ranges can vary slightly depending on the laboratory and specific population.

Interpreting ALT Test Results

Elevated ALT levels can be caused by various factors, including:

• Viral hepatitis
• Alcohol-related liver disease
• Nonalcoholic fatty liver disease
• Certain medications
• Autoimmune liver disorders

Does a high ALT level always indicate severe liver damage? Not necessarily. Mild elevations can occur due to temporary factors like intense exercise or certain medications. Persistent elevations, however, warrant further investigation.

Comprehensive Liver Health Assessment

While ALT is an important marker of liver health, a comprehensive evaluation typically includes other tests and considerations:

1. Aspartate aminotransferase (AST): Another enzyme that can indicate liver damage
2. Alkaline phosphatase (ALP): Elevated levels may suggest bile duct problems
3. Bilirubin: High levels can indicate liver dysfunction or bile duct obstruction
4. Albumin: Low levels may suggest chronic liver disease
5. Prothrombin time: Measures blood clotting ability, which can be affected by liver problems

How often should liver function tests be performed? For individuals without known liver issues, routine testing during annual check-ups is often sufficient. Those with risk factors or existing liver conditions may require more frequent monitoring.

Strategies for Maintaining and Improving Liver Health

Protecting and enhancing liver function is essential for overall well-being. Here are some evidence-based strategies to support liver health:

Lifestyle Modifications

• Maintain a healthy weight: Obesity is a risk factor for nonalcoholic fatty liver disease
• Exercise regularly: Physical activity can help reduce liver fat and improve overall liver function
• Limit alcohol consumption: Excessive alcohol intake is a major cause of liver damage
• Stay hydrated: Proper hydration supports liver function and toxin elimination

Dietary Approaches

Can specific foods support liver health? Yes, certain dietary choices can have a positive impact on liver function:

• Incorporate antioxidant-rich foods: Berries, leafy greens, and nuts can help combat oxidative stress
• Consume adequate fiber: Whole grains, fruits, and vegetables support healthy digestion and liver function
• Include liver-friendly herbs: Milk thistle and turmeric have shown potential benefits for liver health
• Limit processed foods and added sugars: These can contribute to liver fat accumulation

Avoiding Harmful Substances

Protecting the liver from toxins is crucial for maintaining its health:

• Use medications responsibly: Follow dosage instructions and be aware of potential liver-related side effects
• Avoid exposure to environmental toxins: Minimize contact with harmful chemicals and pollutants
• Practice safe behaviors: Use protection during sexual activity and avoid sharing needles to prevent viral hepatitis

Is it possible to reverse liver damage through lifestyle changes? In many cases, especially in early stages of liver disease, adopting healthier habits can significantly improve liver function and potentially reverse some forms of damage.

When to Seek Medical Attention for Liver Concerns

Recognizing the signs of liver problems and knowing when to consult a healthcare professional is crucial for early intervention and optimal outcomes.

Common Symptoms of Liver Issues

• Jaundice (yellowing of the skin and eyes)
• Abdominal pain or swelling
• Chronic fatigue
• Unexplained weight loss
• Dark urine or pale stools
• Nausea or loss of appetite

Should you be concerned if you experience these symptoms? While these signs don’t always indicate liver disease, they warrant medical evaluation, especially if persistent or severe.

Risk Factors Requiring Regular Monitoring

Certain individuals may need more frequent liver health assessments:

• Those with a family history of liver disease
• Individuals with chronic conditions like diabetes or obesity
• People with a history of alcohol abuse
• Those exposed to hepatitis viruses
• Individuals taking medications known to affect liver function

How often should high-risk individuals undergo liver function tests? The frequency of testing depends on individual circumstances, but it’s typically recommended at least annually or as advised by a healthcare provider.

Emerging Treatments and Research in Liver Health

The field of hepatology is continuously evolving, with new treatments and diagnostic tools emerging:

• Advanced imaging techniques for early detection of liver abnormalities
• Novel antiviral therapies for chronic hepatitis
• Targeted therapies for liver cancer
• Regenerative medicine approaches for liver repair

What promising developments are on the horizon for liver disease treatment? Researchers are exploring gene therapy, immunotherapies, and artificial liver support systems, offering hope for improved outcomes in various liver conditions.

In conclusion, maintaining liver health is crucial for overall well-being. Regular monitoring, lifestyle modifications, and prompt attention to potential issues can go a long way in preserving this vital organ’s function. By understanding the various causes of liver problems and the importance of liver function tests like ALT, individuals can take proactive steps to protect their liver health and seek timely medical intervention when necessary.

Types of Liver Problems & Their Causes

Written by Steven Brown

• Infections
• Immune System Problems
• Cancer and Tumors
• Conditions You Inherit
• Other Causes of Liver Disease

Your liver does a lot of things that keep you healthy. It turns nutrients into chemicals your body needs. It filters out poisons. It helps turn food into energy. So when your liver doesn’t work well, that can affect your whole body.

Different things can cause serious liver conditions. You’ll want to know about the top causes.

Sometimes, the problem is that you have an infection that inflames your liver. Viral hepatitis is the most common cause, including:

• Hepatitis A. Most people get it by eating or drinking something that’s tainted by fecal matter. You might not have any symptoms. It usually goes away by itself within 6 months without any long-term harm.
• Hepatitis B. You get it from somebody else, such as through unprotected sex or taking drugs with shared needles. If it lasts longer than 6 months, it makes you more likely to get liver cancer or other diseases.
• Hepatitis C comes from infected blood that gets into your blood. You might get it if you take drugs with shared needles or in connection with HIV. If you’re a health-care worker, you might get it from an infected needle that accidentally sticks you. Symptoms may not show up for many years. For reasons that aren’t quite clear, baby boomers are at risk for hepatitis C and should be tested for it.

Your immune system fights off invaders including bacteria and viruses. But it might go wrong and attack one or more parts of your body, such as your liver.

• Autoimmune hepatitis inflames your liver. It can lead to other disorders and even liver failure. It strikes girls and women more often than boys or men.
• Primary biliary cholangitis attacks tiny tubes in your liver called bile ducts. They carry bile, a chemical that helps you digest food. When the ducts are injured, the bile backs up inside your liver and scars it. Women come down with this more often than men.
• Primary sclerosing cholangitis scars your bile ducts, and it can eventually block them. The bile builds up inside your liver, and that makes it harder for your liver to work. It may lead to liver cancer, and you might someday need a liver transplant. Men are more likely than women to get it.

If cancer shows up in your liver, that’s most likely because it has spread from another part of your body, like your lungs, colon, or breasts. But a few cancers can start in the liver.

• Liver cancer affects women more often than men, and African-Americans more often than whites. Your doctor might call it hepatocellular carcinoma. It’s more likely if you have hepatitis or drink too much.
• Bile duct cancer strikes the tubes that run from your liver to your small intestine to carry bile, a fluid that helps you digest food. This kind of cancer mainly affects people over age 50, but it’s uncommon.
• Liver cell adenoma is a tumor that doesn’t have cancer. It’s uncommon, but women who take birth control pills for a long time are more prone than other people to develop it. There’s a small chance the tumor could eventually turn into cancer.

Some inherited liver disorders only happen if they run in your family.

• Hemochromatosis makes your body store up too much of the iron from your food. The extra iron builds up in your liver, heart, or other organs. It can lead to life-threatening conditions such as liver diseases, heart disease, or diabetes.
• Hyperoxaluria hits when your urine has too much of a chemical called oxalate. In this condition, your liver makes too much oxalate due to a genetic mutation. This can cause kidney stones and kidney failure. If your kidneys do fail, that can give you oxalosis, where the oxalate collects in other organs and causes more trouble.
• Wilson’s disease makes copper build up in your liver and other organs. Its first symptoms usually show up when you’re between the ages of 6 and 35, most often in your teens. It not only affects your liver, but it can cause nerve and psychiatric problems.
• Alpha-1 antitrypsin deficiency involves a chemical that helps your lungs resist infections. Your liver makes it. But when your liver gets the recipe wrong, the faulty chemical can build up and cause liver disease.

• Alcohol abuse can lead to cirrhosis. So can nonalcoholic fatty liver disease and long-term cases of hepatitis B and C.
• Drug overdoses. Taking too much acetaminophen or other medications can harm your liver. Make sure you follow the dosing instructions on the label, and be aware that acetaminophen might be in more than one medicine you take.
• Nonalcoholic fatty liver disease (NAFLD) is when too much fat has built up inside your liver. The extra fat can inflame your liver. One type of NAFLD is nonalcoholic steatohepatitis (NASH). It means you have inflammation and cell damage in your liver, as well as fat. It can scar your liver and lead to other disorders, like cirrhosis.

Dire complications of liver disease include:

• Acute liver failure. This happens when you don’t have a long-term liver disease but your liver quits working within a very short time — days or weeks. That may happen because of an overdose of acetaminophen, infections, or because of prescription drugs.
• Cirrhosisis a buildup of scars in your liver. The more scars replace the healthy parts of your liver, the harder it is for your liver to do its job. Over time, it may not work like it should.

Alkaline Phosphatase Test (ALP): High vs.

Low Levels

Written by WebMD Editorial Contributors

• Why Would I Get This Test?
• How Is the Test Done?
• How Do I Prepare?
• What Do My Results Mean?

Alkaline phosphatase is one kind of enzyme found in your body. Enzymes are proteins that help chemical reactions happen. For instance, they can break big molecules down into smaller parts, or they can help smaller molecules join together to form bigger structures.

You have alkaline phosphatase throughout your body, including your liver, digestive system, kidneys, and bones.

If you show signs of liver disease or a bone disorder, your doctor may order an alkaline phosphatase (ALP) test to measure the amount of the enzyme in your blood and help in diagnosing the problem. Sometimes it’s part of a broader group of tests called a routine liver or hepatic panel, which checks how your liver is working.

If your liver isn’t working right, the amount of ALP in your blood may be high. Doctors often use the test to look for blocked bile ducts. Other conditions that can cause problems with your liver include:

• Liver cancer
• Cirrhosis
• Hepatitis
• Blockage in the bile ducts

The test can also spot problems with your bones, including:

• Cancers that have spread to your bones
• Paget’s disease, which affects how bones grow
• Issues caused by vitamin D deficiency

The lab will need a small amount of blood to perform the test.

The person in charge of taking your blood will start by placing a tight elastic band, called a tourniquet, around your upper arm. This makes your veins swell with blood.

The lab tech will clean an area of your skin with a germ-killing solution. (It might be a spot inside your elbow or the back of your hand). You’ll feel a small stick when the needle goes into your vein. The blood flows into a small vial attached to the needle.

When the test is done, the lab tech will take the tourniquet off, and you’ll get a bandage on the spot where the needle went in. It takes only a few minutes.

Taking blood samples is usually very safe. Some things that might happen after the test include a bruise at the spot where the needle went in, and a little dizziness. There’s also a slight chance of infection.

You may have to limit food and liquids for several hours before the test. Some medicines interfere with the results, so make sure your doctor knows about all drugs you take, including over-the-counter medicines, vitamins, and supplements.

Be sure to let your doctor know if you are pregnant, because that will increase the level of ALP in your blood.

It generally takes 1-2 days for results to come back from the lab.

Higher-than-normal ALP levels for your age and sex may not necessarily mean you have a problem. (Children and teens naturally have higher levels than adults because their bones are still developing).

If your ALP level is high, your doctor may have you take another test, called an ALP isoenzyme test, to determine whether the alkaline phosphatase in your blood is coming from your liver or your bones.

Low levels of ALP indicate a deficiency in zinc and magnesium but can also be an indicator of a rare genetic disease called hypophosphatasia (HPP), which affects bones and teeth.

Liver function, complex of analyzes (liver tests)

A comprehensive analysis for the liver, which includes tests that allow you to evaluate both the general functional state of the liver: ALT, AST; the function of protein metabolism: total protein, albumin, urea; synthesis of bilirubin and bile production: bilirubin and its fractions; bile secretion: GGTP, alkaline phosphatase.

Many types of metabolism take place in the liver cells. Protein metabolism involves enzymes of liver cells (hepatocytes), called transaminases (ALT and AST). An increase in transaminases in the blood can be observed during cytolysis (destruction) of hepatocytes. An increase in ALT often indicates liver damage, while an increase in AST can also be observed with muscle damage, myocardial infarction, hemolysis of red blood cells. In acute viral hepatitis, the levels of enzymes exceed the upper limit of the norm by 5-10 times, and in chronic hepatitis by 1.5-2 times, increasing approximately the same. In alcoholic hepatitis, cirrhosis, liver metastases, there is a predominant increase in AST.

The biliary function of the liver and biliary tract is assessed by the enzymes alkaline phosphatase (AP) and gamma-glutamyl transpeptidase (GGTP). In the case of their simultaneous increase, first of all, obstruction (blockage) of the biliary tract is excluded, for example, with cholelithiasis. High levels of GGTP are characteristic of cirrhosis and liver metastases. A moderate increase in GGTP (2-5 times) is observed in viral hepatitis. Unlike GGTP, alkaline phosphatase also increases in diseases of the bones and intestines.

For hepatic jaundice and obstruction of the biliary tract, the increase in total bilirubin is also typical more due to the direct fraction. Violation of the synthesis of bilirubin occurs with hereditary Gilbert’s syndrome, when there is not enough enzyme that neutralizes indirect bilirubin.

Many drugs are hepatotoxic, causing temporary damage to liver cells. To exclude the development of toxic hepatitis during the treatment of certain diseases, it is necessary to regularly evaluate liver function.

The general assessment of the results of research, the establishment of a diagnosis and the appointment of therapy is carried out by the attending physician.

ALT (ALT, Alanine aminotransferase, alanine transaminase, SGPT, Alanine aminotransferase)

Alanine aminotransferase (AlAT, ALT) is an intracellular enzyme, the content of which in the blood of healthy people is low. It is mainly found in the cells of the liver, myocardium, skeletal muscles, pancreas. When cells containing ALT are damaged or destroyed, the enzyme is released into the bloodstream, and its concentration in the blood increases.

Determination of the level of alanine aminotransferase is carried out for the diagnosis of liver diseases and dynamic monitoring of their treatment. The analysis is performed for suspected acute or chronic hepatitis of viral or toxic etiology, cirrhosis of the liver, primary tumors, or metastatic liver disease.

The growth of alanine aminotransferase in the blood in hepatitis is noted much earlier than the onset of the icteric stage, which makes it possible to identify the pathology at the initial stage.

As part of a screening examination (preventive examination of persons who do not have complaints) to assess the state of the liver, before planned hospitalization and surgical treatment, an analysis for ALT is prescribed together with another enzyme – AsAT (aspartate aminotransferase).

The level of ALT along with other enzymes is evaluated in diseases of the pancreas and gallbladder – pancreatitis, cholecystitis, cholelithiasis; if there are complaints of unexplained general weakness, fatigue, yellowness of the skin and sclera, abdominal pain, including a feeling of heaviness in the right hypochondrium, nausea, vomiting.

In addition, the ALT level is taken into account in myocardial infarction and myocarditis, although in cases of heart damage it is only of secondary importance. The study is prescribed for suspected myositis, myodystrophy, when complaints of muscle pain cannot be explained by injuries or excessive physical activity.

Donation is a mandatory reason for testing for ALT.

ALT values ​​are assessed in any chronic disease, before prescribing drug therapy, for example, antitumor, anti-tuberculosis drugs, to assess the initial state of the liver and over time to assess drug tolerance.

Preparing for the procedure

It is better to take the test in the morning on an empty stomach (after an 8-14 hour break after the last meal).

Drinking water is allowed.

If necessary, donate blood 4-6 hours after a light meal.

On the eve it is desirable to avoid physical and emotional overload, overeating.

Avoid drinking alcohol 5-6 days before the test.

Avoid smoking 30 minutes before blood sampling.

Deadline

The survey is completed within one business day.

What can affect the results

Intense physical activity the day before and even a few days before the test can lead to damage to muscle tissue (the so-called tear of muscle fibers) and, accordingly, an increase in the level of ALT. For the same reason, the analysis given after the injury is not informative.

Alcohol, certain drugs (antibiotics, non-steroidal anti-inflammatory drugs, anticancer drugs, oral contraceptives, etc.) often distort the result of the study. The list of medications taken should be discussed with the doctor who ordered the analysis, cancel those that are possible – without risk to health.

ALT (ALT, Alanine aminotransferase, alanine transaminase)

For research, blood is taken from a vein. Usually, ASAT (AST, Aspartate aminotransferase) is determined simultaneously and the ratio of ASAT / AlAT (de Ritis coefficient) is estimated.

You can take a blood test for ALT (ALT, Alanine aminotransferase, alanine transaminase) at the nearest INVITRO medical office. The list of offices where biomaterial is accepted for laboratory testing is presented in the “Addresses” section.

Interpretation of test results contains information for the attending physician and is not a diagnosis. The information in this section should not be used for self-diagnosis or self-treatment. An accurate diagnosis is made by the doctor, using both the results of this examination and the necessary information from other sources: history, results of other examinations, etc.

Normal

Units of measure: U/l.

Reference values ​​

Explanation of indicators

The level of ALT depends on the age and sex of the patient. Minor deviations from the norm, as a rule, do not require drug therapy, and the recommendations associated with them, such as rational nutrition, avoidance of alcohol, etc. should be discussed with your doctor.

The AST/AlAT ratio (de Ritis ratio) is normally between 0.91 and 1.75.

What do low readings mean

A significant decrease in the level of ALT can be detected in severe liver damage, for example, in the terminal stage of liver cirrhosis, when the number of liver cells is significantly reduced.

What do increased indicators mean

First of all, with an increase in ALT, liver problems should be suspected: fatty hepatosis, hepatitis of viral or toxic etiology, cirrhosis of the liver, liver cancer – primary or metastatic.

The degree of increase in ALT is usually associated with the extent or severity of liver damage, but cannot be considered as a determining factor for the prognosis of the disease. The maximum levels of ALT (and AST) – more than a hundred times higher than the norm, are observed in patients with acute viral and drug-induced hepatitis.

A significant increase in alanine aminotransferase can be observed in acute cholecystitis, cholelithiasis, and acute destructive pancreatitis. Another reason may be the use of hepatotoxic drugs that damage liver cells.

An increase in the level of ALT is detected with extensive injuries of the skeletal muscles, severe myositis and myodystrophy, frequent intramuscular injections.

A less significant increase in ALT is recorded in acute myocardial infarction and myocarditis.

Additional examination in case of deviation of the indicator from the norm

If a change (often an increase) in the level of ALT is detected, patients are consulted

general practitioners

,

gastroenterologists

, hepatologists, infectious disease specialists.

To clarify the diagnosis, in addition to ALT, other liver enzymes (AST, gamma-HT, alkaline phosphatase, bilirubin), clinical blood counts, and markers of viral hepatitis, primarily hepatitis B and hepatitis C, are usually examined.

An ultrasound examination of the abdominal organs is performed, according to indications – computed tomography (CT) with contrast.

If damage to the skeletal muscles is suspected, the CPK enzyme is additionally examined and a rheumatologist is consulted.

If a heart muscle disorder is suspected, a cardiologist should be consulted. Usually, the doctor prescribes additional electrocardiography (ECG), echocardiography, blood test for CF-CF, troponin I.
