What is Hepatomegaly?

“Hepatic” refers to the liver and “megaly” refers to an increase in size. Hepatomegaly is a medical term which means an increase in the size of the liver.

The liver is situated in the upper right quadrant of the abdomen. It is a very vital organ in the human body. It is responsible for the digestion of fats (broken down by bile secreted by liver cells), storage of glucose in the form of glycogen and metabolism of the pharmaceutical drugs that we consume.

The factors that affect the size of the liver are age, gender, body weight and body shape. A liver that is 3 centimeters larger or smaller is still considered normal. If enlarged beyond the normal limits, it is good to get a medical evaluation done to find the underlying cause.

Diseases that cause the liver to get enlarged have to be treated immediately since they interfere with the liver’s functionality.

What are the Causes of Hepatomegaly?

Some of the known causes of hepatomegaly are

What are the Signs and Symptoms of Hepatomegaly?

Symptoms of hepatomegaly are serious and have to be evaluated as soon as possible.
  • Jaundice [yellowing of the skin and eyes]
  • Fever, if infection is the causative factor
  • Nausea and vomiting
  • Tiredness
  • Loss of appetite
  • Pain in abdomen and feeling of distension

Signs and Symptoms of Hepatomegaly

How do you Diagnose Hepatomegaly?

The doctor will first ask for the medical history and conduct a physical examination to check the liver. Palpation and percussion in the upper right quadrant of the abdomen gives a rough estimate of the size and texture of liver. Further tests might be suggested if an enlarged liver is suspected.
  • Raised levels of liver enzymes. Also known as liver function tests (LFT), they monitor levels of ALT [alanine aminotransferase], AST [aspartate aminotransferase], alkaline phosphatase, albumin and bilirubin. Raised levels of ALT and AST suggest liver disease, whereas high levels of alkaline phosphatase indicate an obstruction in the bile flow. Raised levels of bilirubin [a yellow substance formed by breakage of red blood cells in liver] and albumin [a protein made in liver] indicate that the liver is not functioning properly.
  • Blood tests will measure any raised levels of antibodies in Hepatitis A, B, C infections and also prothrombin time [PT] which is a blood clotting factor made by liver.
  • Abdominal ultrasound helps to determine size of liver, dilatation or narrowing of bile duct or blood vessels, tumors and abscesses.
  • Computerized tomography (CT) scan gives detailed images of the internal organs, bones, soft tissue and blood vessels.
  • Magnetic resonance imaging (MRI). MRI uses a strong magnetic field and radio waves to create detailed images of the organs and tissues within the body.

What are the Complications of Hepatomegaly?

Early diagnosis and treatment are vital to prevent any complications that could be fatal. An enlarged liver may lead to inflammation and cirrhosis if there is regular alcohol intake, poor control of diabetes, hyperlipidemia, and chronic viral infections.
  • Liver failure.
  • Cirrhosis or replacement of normal liver tissue by scar tissue.
  • Encephalopathy, which includes mental confusion, slurry speech, seizures, sleepiness, and coma.
  • Bleeding problems due to insufficient amounts of clotting factors being produced by liver.

How do you Treat Hepatomegaly?

Treatment will vary according to the underlying cause of hepatomegaly.
  • Hepatitis B is treated with drugs such as adefovir dipivoxil, entecavir, lamivudine, and interferon.
  • Hepatitis C is treated with drugs such as boceprevir, daclatasvir, interferon, ribavirin, and sufosbuvir.
  • Hepatitis A & E are self limiting diseases. Adequate rest, healthy nutrition and abstaining from alcohol are usually advised.
  • If the liver enlargement is alcohol related then complete abstinence from alcohol, adequate rest, healthy and low fat diet are recommended.
  • Liver transplant is an option in cases of liver failure.
  • Surgical resection of the diseased liver part is an option in liver disease.
  • Chemotherapy and radiation are treatment options for liver cancer.
  • In cases of ascites [accumulation of fluid in abdomen], paracentesis is performed to drain the excess fluid.
  • Homeopathic medicines such as chelidonium majalis, cardus marianus, lycopodium clavatum have proven beneficial in treating liver inflammation.
  • Lifestyle changes like maintaining healthy weight in obese people and keeping normal sugar levels have to be followed.

How do you Prevent Hepatomegaly?

Hepatomegaly can be prevented by:
  • Stopping intake of alcohol.
  • Keeping blood sugar under control.
  • Preventing viral infections hepatitis A and B by vaccination.
  • Practicing safe sex.
  • Eating healthy. Avoid white flour, sugar, and white rice. Include whole wheat flour, brown rice, and multigrain flour in the diet. Also include plenty of vegetables [cooked and raw], and proteins from eggs, lean meat, fish, nuts, legumes, seeds, greek yogurt in the daily diet.
  • Including healthy fats such as extra virgin olive oil for cooking and salad dressings. Also eat a low fat diet. Avoid saturated fats /trans fats.
  • Keeping weight under check. Avoid drastic weight fluctuations.
  • Exercising regularly.
  • Avoiding contact with toxic chemicals.
  • Choosing herbal medicines and dietary supplements carefully.
