All about Enlarged Liver

All About Enlarged Liver

The liver is an essential organ of the human body. It performs many important functions like filtering toxins from the blood, helping digest food, synthesizing protein, and storing vitamins and minerals.

When the liver becomes larger than its normal size, it is known as the enlarged liver. It is also known as hepatomegaly.

Although it is not a disease, it appears as a symptom of other underlying issues. For example, it may result from liver disease, cancer, and congestive heart failure.

The treatment of this symptom begins according to the condition involved in it. The physician starts the therapy only after identifying the cause of the disease.


What causes enlarged liver?

The size of the liver varies from person to person. It varies according to the body’s age, sex, and size. There are many reasons for enlarged liver. These are:

Some mild or severe liver diseases may cause an enlarged liver. These diseases include:

Apart from these diseases, if any fatty substance or iron or copper or protein in an excessive amount accumulate in your liver, you may have an enlarged liver

Sometimes toxic hepatitis or liver cysts may also lead to a swollen liver.


If cancer originating in the other part spreads to the liver, your liver may become bigger than normal.

Other causes like leukemia, liver cancer, or Lymphoma may be the reason for a swollen liver.

Problems in heart and blood vessel

Heart failure, blockage in the veins draining the liver, and inflammation of the tissue around the heart are some of the reasons for an enlarged liver.

Enlarged liver causes inflammation, indicating the infection or other problems associated with the liver.


What are the symptoms of the enlarged liver?

When you feel too tired and sleepy, you experience fatigue. You do not feel refreshed even after taking sufficient rest when you get fatigued. Fatigue interrupts your daily activities by making you feel too tired and sleepy.
