Fatty liver disease means excess fat stored in liver cells. It often develops quietly and can be without clear symptoms, but diagnosis, risk control and appropriate follow-up are important. If you have severe abdominal pain, jaundice, confusion or breathing difficulty, seek emergency care immediately.
What it is and the main types
Fatty liver can be classified as alcohol-related or non-alcoholic. Alcohol-related fatty liver is linked to long-term, heavy alcohol use. Non-alcoholic fatty liver disease (NAFLD) is commonly associated with metabolic factors such as obesity, insulin resistance and type 2 diabetes; a subset with inflammation and liver cell injury is called non-alcoholic steatohepatitis (NASH).
Who is more likely to develop it?
Frequently associated risk factors include overweight or obesity, type 2 diabetes, insulin resistance, high triglycerides or cholesterol, and metabolic syndrome. Rapid weight changes, older age, certain medications and excess alcohol also increase risk.
Signs and how it’s diagnosed
Many people have no clear symptoms; some report fatigue or mild discomfort in the upper right abdomen. Initial evaluation typically includes blood tests for liver enzymes and imaging such as liver ultrasound. When needed, further tests like transient elastography (FibroScan) or other imaging, and in selected cases a liver biopsy, help assess inflammation and fibrosis — decisions made by a specialist.
Management, follow-up and possible complications
Lifestyle measures — weight management, a balanced diet and regular physical activity — form the cornerstone of care. Controlling associated metabolic conditions is important. In some people, ongoing inflammation can lead to fibrosis or, rarely, cirrhosis; regular medical review helps detect progression early.
When to seek care and specialist referral
Seek urgent care for sudden severe abdominal pain, yellowing of the skin or eyes, sudden confusion or new breathing problems. For assessment and routine management, start with primary care (family medicine); referral to Gastroenterology or Hepatology is common for staging and specialist advice. If metabolic disease is present, Endocrinology may be involved.
