Fatty liver disease (hepatic steatosis) occurs when excess fat builds up in the liver, often due to obesity, poor diet, or metabolic conditions like diabetes. It can also result from heavy alcohol use (Alcoholic Fatty Liver Disease) or lifestyle factors unrelated to alcohol (Non-Alcoholic Fatty Liver Disease).

Often symptomless, fatty liver is sometimes discovered during routine checkups. When symptoms occur, they may include fatigue, abdominal discomfort, or jaundice.
Prevention and management focus on lifestyle changes:
- Healthy Diet: Eat whole foods, avoid processed items and saturated fats.
- Exercise: Aim for at least 150 minutes of moderate activity weekly.
- Weight Loss: Gradual weight loss supports liver health.
- Limit Alcohol: Especially crucial for those with AFLD.
- Manage Health Conditions: Control diabetes, cholesterol, and blood pressure.
Some supplements like milk thistle, omega-3s, vitamin E, and green tea may offer support—but consult a doctor first.
