There are two main types: non-alcoholic fatty liver disease (NAFLD), linked to obesity and poor lifestyle, and alcoholic fatty liver disease, caused by excessive alcohol use. NAFLD is the most common and often shows no symptoms early on, but can lead to fatigue, abdominal discomfort, and liver inflammation as it progresses.

If untreated, it may develop into more serious conditions like NASH, fibrosis, cirrhosis, or liver cancer. Diagnosis is done through blood tests, imaging, or liver biopsy.

There’s no specific medication for NAFLD, but lifestyle changes—gradual weight loss, a healthy diet, regular exercise, avoiding alcohol and smoking, and managing related conditions—can reverse it. The liver can regenerate, so early action is key.

In short, fatty liver is common but often reversible with timely lifestyle changes and medical guidance.
