Fatty Liver Disease (NAFLD / MASLD)
Obesity Videos
Overview
Fatty liver disease—now termed MASLD (Metabolic Dysfunction‑Associated Steatotic Liver Disease)—is a condition where excess fat builds up in the liver. It is strongly linked to obesity, insulin resistance, type 2 diabetes, and metabolic syndrome. While early stages are reversible, progressive inflammation can lead to fibrosis, cirrhosis, and liver failure if untreated.
Causes
Causes include obesity, insulin resistance, type 2 diabetes, high triglycerides, poor diet, sedentary lifestyle, and certain medications. Metabolic dysfunction is the primary driver.
Risk Factors
Risk factors include obesity (especially central obesity), metabolic syndrome, type 2 diabetes, high triglycerides, hypertension, sleep apnea, and family history of liver disease.
How Fatty Liver Disease Affects the Body
Fat accumulation triggers inflammation and scarring in the liver. Over time, this can progress to fibrosis, cirrhosis, portal hypertension, liver cancer, and liver failure.
Complications
Complications include NASH (steatohepatitis), fibrosis, cirrhosis, liver cancer, cardiovascular disease, and increased mortality.
Symptoms & Signs
Most patients have no symptoms. Some may experience fatigue, right‑upper‑quadrant discomfort, elevated liver enzymes, or signs of advanced liver disease in later stages.
Diagnosis
Diagnosis includes liver function tests, ultrasound, FibroScan, MRI, and metabolic labs. Liver biopsy is used when advanced disease is suspected.
Differential Diagnosis
Includes alcoholic liver disease, viral hepatitis, autoimmune hepatitis, hemochromatosis, Wilson’s disease, and medication‑induced liver injury.
Lifestyle Modifications
Lifestyle strategies include weight loss, reduced sugar intake, Mediterranean‑style diet, increased physical activity, improved sleep, and limiting alcohol.
Treatment Options
Treatment includes medical weight management, anti‑obesity medications, metabolic surgery, diabetes control, lipid management, and monitoring for fibrosis progression. Bariatric surgery is one of the most effective treatments for reversing fatty liver disease.
When to See a Doctor
Seek evaluation if you have obesity, diabetes, abnormal liver tests, or imaging showing fatty liver.
When to Seek Treatment
Treatment is recommended when liver enzymes are elevated, when fibrosis is present, or when metabolic risk factors are uncontrolled.
Long-Term Outlook
Long‑term management focuses on weight reduction, metabolic control, and regular liver monitoring. Bariatric surgery offers durable improvement for many patients.
Prognosis
Early fatty liver disease is reversible. Without treatment, it may progress to cirrhosis or liver failure.
