Non-alcoholic steatohepatitis

Non-alcoholic steatohepatitis (NASH) is a type of fatty liver disease, which is characterized by inflammation and accumulation of fat in the liver. It is not related to alcohol consumption.

Pronunciation

Non-alcoholic steatohepatitis is pronounced as non-al-ko-hol-ik stee-at-oh-hep-a-titis.

Etymology

The term "Non-alcoholic steatohepatitis" is derived from the following Greek words: "steatos" meaning fat, "hepatos" meaning liver, and "itis" meaning inflammation. The prefix "non-alcoholic" is used to differentiate it from alcohol-related liver diseases.

Definition

Non-alcoholic steatohepatitis (NASH) is a severe form of non-alcoholic fatty liver disease (NAFLD). It is characterized by the presence of an abnormal accumulation of fat in the liver which is not caused by excessive alcohol consumption. NASH is associated with liver inflammation and damage that can lead to the development of fibrosis, cirrhosis, or liver cancer.

Symptoms

The symptoms of NASH are often silent or non-specific, making it difficult to diagnose. However, some people may experience fatigue, weight loss, and pain in the upper right abdomen.

Causes

NASH is usually seen in people who are obese or have type 2 diabetes, high cholesterol or high triglycerides. Rapid weight loss and poor eating habits also may lead to NASH. However, some people with NASH are not obese and do not have diabetes.

Treatment

There is no specific treatment for NASH. However, managing the conditions that can contribute to NASH, such as obesity and diabetes, can help to control the progression of the disease.
