What is Hepatomegaly?
Hepatomegaly is a medical condition that is due to the enlargement of the liver. An enlarged liver is one that is bigger than the normal size. Normally, the liver swells as a symptom of another health condition like hepatitis. The liver performs a lot of vital jobs. It helps to clean the blood by getting rid of harmful chemicals. It also makes bile that breaks down fat from food. Moreover, the liver stores sugar known as glucose, which gives people the required energy whenever they need it. Therefore, an enlarged liver can cause lethal complications.

The symptoms of an enlarged liver are feeling of fullness, discomfort in the belly, yellowing of the skin or eyes (jaundice), fatigue, weakness, nausea, and weight loss. Hepatomegaly can be caused due to obesity, infections (hepatitis B and C), medications, consumption of a lot of alcohol, toxins, autoimmune disease, metabolic syndrome, genetic disorders, cysts, tumors, congestive heart failure, hepatic vein thrombosis, and veno-occlusive disease. Hepatomegaly is usually diagnosed through physical examination, CT scan, MRI, ultrasound, and liver biopsy. Losing weight, cutting back on alcohol use, eating a healthy diet, and getting more physical activities are some of the treatments.
What is Fatty Liver?
Fatty liver is a medical condition occurring due to the storage of extra fat in the liver. Most people show no symptoms. However, in some cases, it can lead to liver damage. The symptoms of fatty liver disease include abdominal pain, nausea, loss of appetite, weight loss, yellowish skin and whites of the eyes (jaundice), swollen abdomen and legs (edema), and extreme tiredness and weakness. Moreover, there are two types of fatty liver disease: alcoholic and non-alcoholic. Alcoholic fatty liver is due to heavy drinking. On the other hand, fatty liver disease can be caused by obesity and diabetes. The other causes of fatty liver include metabolic syndrome (insulin resistance, high blood pressure, high cholesterol, and high triglyceride) and taking some prescription medicines such as amiodarone, diltiazem, tamoxifen, and steroids.
