Is an enlarged liver dangerous?

An enlarged liver can be a warning of a health problem which may be straightforward to treat or could be serious or very serious. If you have established the cause, how severe it is and what the symptoms are, that will help determine if it is dangerous. 
Sometimes, it is Dangerous:

  • If it’s caused by ongoing liver damage (such as cirrhosis, cancer)
  • If your liver is damaged and doesn’t work properly, you may develop jaundice, confusion or suffer from bleeding problems.
  • If it is related to disease of the system, for example, heart failure or cancer

Enlarged Liver Causes and Symptoms

What causes an enlarged liver?

An enlarged liver (hepatomegaly) is a symptom linked to a wide variety of health problems affecting the liver, either directly or indirectly. In this section, we list the most common causes:

Liver Diseases

Fatty Liver Disease

  • Non-alcoholic fatty liver disease (NAFLD) – Linked to excessive weight, diabetes and too much cholesterol.
  • Alcoholic liver disease is caused by regularly drinking a lot of alcohol.

Hepatitis

  • Hepatitis is a condition commonly called viral hepatitis (A, B, C, etc.).
  • Autoimmune hepatitis

Cirrhosis (early stages)

  • Continued damage to the liver leading to scars.

Liver Cancer or Metastatic Cancer

  • Any cancer that first appears or later involves the liver.

Heart and Blood Vessel Diseases

  • A common heart problem, congestive heart failure
  • A slowed blood flow causes the liver to become inflamed and bigger.

Budd-Chiari syndrome

  • Liver veins are blocked.

Metabolic and Genetic Disorders

  • Hemochromatosis
  • Having too much iron in your body is called iron overload disorder.

Wilson’s disease

  • A collection of copper in the liver and other body tissues.

Among these are Gaucher’s disease, amyloidosis and many other storage disorders.

Infections

  • Mononucleosis is caused by Epstein-Barr virus.
  • The diseases include malaria, leptospirosis and tuberculosis.

Interactions between toxins and medication

  • Using certain medications—for example, methotrexate and amiodarone—over time
  • Supplements made from herbs or toxins harmful to the liver

Obstruction or Biliary Disorder

  • Gallstones may also cause problems with the bile duct.
  • Medical experts use both primary biliary cholangitis and primary sclerosing cholangitis for this condition.

Symptoms of Enlarged Liver

Symptoms of an enlarged liver depend on its cause, how large it is and if it can still work properly. Usually, an enlarged liver is noticed accidentally through a physical exam or an imaging test that doesn’t involve any symptoms.

Symptoms:

Abdominal symptoms or pain

  • Typically, you will find it in the upper right side under the ribs
  • May make your stomach feel bloated, -weighted or vaguely painful

You may feel bloated or like you’ve eaten too much

  • Even if you eat less as a result of stomach pressure

When you’re feeling tired or weak

  • Feeling less energy

Upset stomach or loss of appetite

Weight loss that happens without trying

Severe symptoms (Liver dysfunction signs):

They may point toward the condition getting worse.

  • A yellowish color in the skin and eyes is called jaundice.
  • If your urine is dark and your stool is light, there might be a problem.
  • Itchy skin
  • Water on the abdomen (ascites) or in the legs
  • Having trouble concentrating or understanding (due to the liver working improperly on brain chemicals).
  • Having trouble with small injuries causing serious bleeding

Enlarged Liver Treatment

The enlarged liver is a sign, rather than a disease itself, treatment has to vary from case to case. The main goal is to find and address the main problem. Following are some of the most common causes and the usual ways they are controlled:

Problems with Fatty Liver Disease (NAFLD/NASH)

Treatment is mainly based on changing your lifestyle:

  • Reduce your overall weight by only 5–10% each month.
  • Try a diet that is low in both fat and sugar, in the style of the Mediterranean.
  • Avoid both alcohol and foods that are processed or packaged.
  • Try to exercise for at least 150 minutes each week.

Alcoholic Liver Disease

  • Don’t drink alcohol anymore
  • Proper food and, if necessary, alcohol-dependent medications
  • Work on nutritional deficiencies, especially those involving the B vitamins, thiamine.

Hepatitis

  • Hepatitis B/C that can spread from one person to another:
  • For Hep B, drugs such as entecavir and tenofovir are used and direct-acting antivirals are given for Hep C.

Autoimmune hepatitis:

  • Examples of immunosuppressants are corticosteroids and azathioprine

Cirrhosis

  • Medically address what is causing the disease (for example, alcohol or hepatitis)
  • Do not use drugs that can harm the liver such as NSAIDs and a few antibiotics.
  • Look out for and treat conditions like ascites, bleeding or encephalopathy
  • In some very critical cases, patients need liver transplantation.

Liver Cancer

Treatment options:

  • Surgery
  • Liver transplant
  • You may get chemotherapy or a targeted therapy.
  • Radiofrequency ablation is a different method than embolization.

Heart-Related Problems (such as Congestive Heart Failure)

  • To treat the heart problem, use diuretics, ACE inhibitors and beta-blockers.
  • Avoid too much fluid in your body and work to keep blood flowing properly

Metabolic or Genetic Disorder

  • Hemochromatosis: Your doctor will regularly remove blood (phlebotomy).
  • Wilson’s disease: Treating with copper chelating medications like penicillamine
  • Gaucher’s and similar disorders are treated with enzyme replacement therapy.

Fatty Liver vs Enlarged Liver

Fatty Liver

Fatty liver or hepatic steatosis, develops when too much fat accumulates within liver cells. Often, the cause is excess metabolism, using too much alcohol or improper nutrition. The two classes of fatty liver disease are called Non-Alcoholic Fatty Liver Disease (NAFLD) and Alcoholic Fatty Liver Disease. Experts regularly link NAFLD with obesity, diabetes, excessive cholesterol and no regular exercise. Though fatty liver may not produce symptoms in the beginning, it may worsen to inflammation, the hardening of tissue or ultimately to liver failure. Patients are advised to eat healthy, lose weight and exercise. It is often possible to reverse fatty liver by pushing forward and acting quickly.

Enlarged Liver

An enlarged liver is a condition that shows itself in symptoms, but is not directly called a disease. When the liver increases in size, the condition may be caused by many things such as fatty liver. Some examples of other causes are viral hepatitis, liver cancer, heart failure, diverse hereditary diseases and specific infections. A liver can sometimes be enlarged without becoming fatty and at other times can be enlarged and fatty. Those experiencing an enlarged gallbladder may often experience right upper abdominal pain, a bloated feeling or fullness. If you have an enlarged liver, the main concern is to manage the basic illness that caused it, since restoring liver health starts by treating the primary illness.

Enlarged Liver and Pain in Right Side

Abdominal pain in the right side, around the ribs, is a frequent symptom of an inflamed liver. It happens most often due to the liver stretching the outer capsule or because nearby organs are being compressed.

Why an Enlarged Liver Causes Right-Sided Pain?

At the upper right side of your abdomen, beneath your diaphragm and ribs, is where you’ll find the liver. When the gland grows larger, it can cause the following:

  • Gently stretch the capsule over the liver (Glisson’s capsule) since it contains nerves that are a source of pain.
  • Press on your other abdominal areas such as the stomach or intestines.
  • The liver becomes inflamed in both hepatitis and fatty liver with inflammation.

Enlarged Liver and Fatty Liver Disease

Enlarged liver and fatty liver disease is not identical, but they are related. Hepatomegaly often happens in fatty liver disease — however, other causes are also possible. 

How Fatty Liver Leads to Enlarged Liver?

In people with fatty liver disease:

  • The liver tends to store fats which cause it to swell.
  • A buildup of fat in the liver causes it to swell.
  • When the liver’s capsule is stretched, people often feel discomfort or pain in the right upper abdomen.

Enlarged Liver in Adults

When the liver is bigger than usual (hepatomegaly), it reveals there’s a problem. Many adults may have hepatitis which can go from having no signs to producing symptoms of liver dysfunction. The danger of a tumor is decided by what causes it.

What Leads to Enlarged Liver in Adults?

In adults, another reason for an enlarged liver is possible damage to the liver, heart, infections, metabolic diseases or cancer.

Fatty Liver Disease

  • Non-Alcoholic Fatty Liver Disease is the term used for this condition.
  • Being linked to obesity, diabetes and problems such as high cholesterol and diet.
  • Alcoholic Liver Disease
  • Because of excessive drinking

Hepatitis

  • All types of viral hepatitis, including A, B and C.
  • Autoimmune hepatitis
  • Drugs or toxins may be the cause of hepatitis.

Cirrhosis 

  • Because of chronic issues such as alcohol and hepatitis

Liver Tumors

  • One form of primary liver cancer is called hepatocellular carcinoma.
  • Metastases of cancer have spread from the colon, breasts, lungs and other organs.

Heart-Related Causes

  • When there is congestive heart failure, blood pools in the liver.
  • A blockage in the liver’s veins is the main characteristic of Budd-Chiari syndrome.

Metabolic/Genetic Conditions

  • The disease known as hemochromatosis
  • An accumulation of copper in the body leads to Wilson’s disease.
  • Amyloidosis and Glycogen storage diseases

Infections

  • Mononucleosis (EBV)
  • Liver abscess
  • Examples of these are parasitic infections like hydatid cyst.
