Fatty Liver Disease: Causes, Symptoms, and Prevention
What is fatty liver disease?
Fatty liver disease occurs when excess fat builds up in liver cells. Non-alcoholic fatty liver disease (NAFLD) — the form unrelated to alcohol use — is increasingly common and is closely linked to obesity, diabetes, and high cholesterol.
Why it’s often missed
Early fatty liver disease usually causes no symptoms and is frequently discovered incidentally during a routine ultrasound or blood test done for another reason. Some people experience mild fatigue or discomfort in the upper right abdomen as it progresses.
Common risk factors
Being overweight, type 2 diabetes, high triglycerides, high blood pressure, and a sedentary lifestyle are the most common contributors. Genetics and certain medications can also play a role.
Protecting your liver
Gradual, sustained weight loss, regular exercise, a diet lower in refined sugar and saturated fat, and managing related conditions like diabetes and cholesterol are the main evidence-based ways to support liver health.
When to see a doctor
If routine blood tests show elevated liver enzymes, or an ultrasound notes fatty changes in the liver, a consultation can help identify contributing factors and set out a monitoring and lifestyle plan.
