Fatty Liver Disease: The Silent Epidemic Most People Don't Know They Have

It is estimated that 80 to 100 million Americans have non-alcoholic fatty liver disease (NAFLD) — making it the most common liver condition in the United States. Yet the vast majority of people who have it don't know. No symptoms. No warning signs. Just fat quietly accumulating in the liver while life carries on as normal.
That's what makes NAFLD dangerous. By the time many patients learn they have it, some degree of damage may already have occurred. Understanding this disease — and catching it early — is one of the most important things you can do for your long-term liver health.
What Is Fatty Liver Disease?
NAFLD is the buildup of excess fat in liver cells in people who drink little or no alcohol. It exists on a spectrum. At one end is simple steatosis — fat in the liver with no inflammation or damage. This is the mildest form and often reversible with lifestyle changes. At the more serious end is non-alcoholic steatohepatitis (NASH) — fat plus inflammation and liver cell injury that can lead to fibrosis (scarring), cirrhosis (advanced scarring), and ultimately liver failure or liver cancer.
Who Is at Risk?
NAFLD is closely linked to metabolic health. The primary risk factors are:
Obesity or overweight (especially belly fat)
Type 2 diabetes or insulin resistance
High triglycerides or low HDL ('good') cholesterol
High blood pressure
Metabolic syndrome (a cluster of the above)
If you have any of these conditions, you are at elevated risk for NAFLD and should ask your doctor to check your liver function and consider a formal evaluation.
How Is It Diagnosed?
NAFLD is most often discovered incidentally — either through abnormal liver enzymes (ALT, AST) on routine bloodwork, or through an abdominal ultrasound ordered for another reason that shows a 'bright' or echogenic liver. A gastroenterologist or hepatologist should evaluate any patient with persistently elevated liver enzymes.
Advanced Gastroenterology Group offers FibroScan — a non-invasive, painless test that uses ultrasound technology to measure both liver fat content and liver stiffness (a marker of fibrosis). FibroScan provides critical information about disease severity in most patients without the need for a liver biopsy.
Can Fatty Liver Disease Be Treated?
Yes — and the most effective treatment is also the most straightforward: sustained weight loss. Studies consistently show that losing 7–10% of body weight reduces liver fat, decreases inflammation, and can even reverse fibrosis. The challenge, of course, is that losing and maintaining that weight is easier said than done.
Our NAFLD program at Advanced Gastroenterology Group takes a structured, medically guided approach. We partner with certified nutritionists through Sylvan Health (often covered by insurance) for telehealth dietary counseling, provide exercise guidance, and offer GLP-1 medication support for eligible patients. Close monitoring with bloodwork and follow-up FibroScan allows us to track your progress and adjust your plan.
What Happens If It's Not Treated?
Untreated NASH can progress to cirrhosis over years to decades. Cirrhosis is irreversible — the liver becomes scarred and unable to function properly, leading to serious complications including liver failure, portal hypertension, and hepatocellular carcinoma (liver cancer). Early intervention, when the disease is still at the fatty liver or early NASH stage, offers the best opportunity to change the trajectory.
