The human liver is a highly active and essential part of the body. It performs crucial functions such as filtering blood, storing glucose, aiding in the digestion process, and much more. However, in certain cases, the liver can outgrow its actual size, a condition commonly known as hepatomegaly (enlarged liver). This condition, although rare, is often a sign of other underlying health issues. In most cases, the enlargement is not immediately obvious and therefore often goes unnoticed until other symptoms, such as pain in the upper abdomen, uneasiness, or discomfort, become apparent.

These symptoms can indicate health issues such as liver damage, infection, or heart conditions. Healthcare providers often treat hepatomegaly by finding out its cause and addressing the underlying condition. For instance, if the enlargement is due to an infection, doctors may prescribe antiviral drugs to cure it. On the other hand, if it is caused by a fatty liver, they might recommend some lifestyle modifications such as a healthy diet, regular exercise, and weight management strategies. In the article below, we will take a closer look at hepatomegaly (enlarged liver), its causes, symptoms, and available treatment options.

What is Hepatomegaly?

When the human liver swells up or expands beyond its actual size, the condition is known as hepatomegaly. This enlargement is one of the primary symptoms associated with liver diseases. However, it can also occur from other issues such as excessive stress, blood or heart-related diseases, and injuries. In a normal healthy body, the liver is often behind the ribcage and cannot be easily felt. However, when it gets swollen, it is easily noticeable in any physical examination. Due to the enlargement, the organ may also show differences in terms of its texture and firmness. It can be studied through imaging or blood tests. Nevertheless, it is crucial to know that hepatomegaly isn’t a disease in itself but rather a physical symptom of various other conditions such as fatty liver, hepatitis, cardiac issues, or inflammation.

Hepatomegaly Causes

There are several conditions that can lead to an enlarged liver, and knowing the right cause is crucial for doctors to come up with the correct hepatomegaly treatment plan. Some of the known causes include:

Liver Diseases

Hepatitis: In hepatitis, the liver cells swell up either due to an infection, alcohol, drugs, etc, leading to complete organ enlargement.

Cysts in the liver: Cysts or abscesses in the liver may occupy unnecessary space, causing the organ to swell up.

Fatty liver disease: As the name suggests, there is fat buildup in the liver, either due to excessive alcohol consumption, insulin resistance, or metabolic conditions such as obesity.

Blood-related conditions

A smooth blood flow is crucial for the liver’s optimal functioning. In conditions where the blood flow gets restricted or when the heart isn’t able to effectively pump blood, it causes an excess blood backup in the liver, giving way to hepatomegaly.

Tumours

Abnormal growths or tumours in the liver can cause hepatomegaly. Regardless of whether the growths are cancerous or benign, they spread in the liver, affecting the organ’s shape, size, and texture. Furthermore, in most cases, the enlargement is easily noticeable as compared to the other symptoms associated with the condition.

Hepatomegaly Symptoms

Hepatomegaly symptoms vary based on the causing factors and the extent to which the enlargement has taken place. In most cases, it may even go unnoticed until the liver’s functioning gets hampered and starts affecting daily life. Some of the common hepatomegaly symptoms include abdominal swelling, fatigue, discomfort, jaundice, loss of appetite, and pain.

How is Hepatomegaly and Its Causes Diagnosed?

Means such as physical examinations, imaging tests, blood tests, or a biopsy are often used to diagnose hepatomegaly and its causes.

Physical Examination: A physical exam is a simple process in which the doctor touches your abdomen to feel for any abnormalities in the shape, size, or texture of your liver.

Imaging Tests: If the doctors suspect an enlargement through the physical exam, you may be asked to undergo an imaging test, preferably a simple ultrasound, to get a clearer picture of the level of enlargement. In certain cases, if the hepatomegaly is severe, a CT scan may also be performed to check for other signs such as abnormal growths, changes in the blood flow, etc. These symptoms could indicate other severe health complications.

Blood Tests: The most common type of blood tests performed to check the liver’s condition are the LFT – Liver Function Tests. These tests help assess liver health by calculating the enzyme levels, bilirubin, proteins, and other substances associated with its optimal functioning. Abnormalities in the report can point to hepatomegaly, infections, or signs of liver damage. In severe cases, additional blood tests may also be recommended to check for conditions such as hepatitis.

Biopsy: When both imaging and blood tests fail to give clear answers, a biopsy is conducted. In this process, a small tissue is abstracted from the liver, which is then analysed thoroughly under a microscope to find out the condition causing hepatomegaly.

How is Hepatomegaly Treated?

Hepatomegaly treatment revolves around identifying and managing the condition causing the enlargement and, therefore, can vary from person to person. However, some of the common treatment options are as follows:

Dietary Changes: One of the common hepatomegaly causes includes fat build-up, and making dietary changes is the first step towards reducing it. Practicing healthier eating habits and cutting down on liquor are highly recommended.

Medications: If the hepatomegaly is caused by an infection, antiviral medications are given to manage it and reduce the swelling. In cases of the hepatitis virus, long-term treatment may be needed to control its progression and reduce liver swelling.

Cardiac or Blood Circulatory Support: When blood flow problems cause unnecessary pressure on the liver, heart medications or diuretics may be given to reduce fluid retention in the body and promote better blood circulation.

Surgical Treatment: Used in conditions when there is an abnormal growth in the liver causing intense damage or pain. Nevertheless, it depends on the type, size, and stage of the tumour/growth.

Conclusion

Liver enlargement is often a sign of other health conditions, and ignoring it can lead to severe complications that can be hard to manage later on. Therefore, it is best to visit your healthcare provider the moment you experience any of the signs and symptoms mentioned above. Early diagnoses and treatment can help manage the underlying cause effectively, preventing further liver damage and ensuring better health outcomes.

FAQs

1. Can children get hepatomegaly?

Yes, hepatomegaly can occur in people of any age.

2. Is hepatomegaly the same as fatty liver?

No, they aren’t the same thing. Hepatomegaly refers to the enlargement of the liver, while fatty liver refers to a condition in which fat builds up in liver cells. This condition can cause hepatomegaly as well.

3. When should I see a doctor for hepatomegaly?

If you experience symptoms such as abdominal pain, discomfort, fatigue, and loss of appetite, it could be a sign of hepatomegaly, and it is best to visit your doctor at the earliest.
