Fatty liver disease: the silent path to liver failure — and how to stop it

What is fatty liver disease?

Fatty liver disease — now called MASLD (metabolic dysfunction-associated steatotic liver disease, previously NAFLD) — means excess fat has accumulated in the liver cells of a person who drinks little or no alcohol. It is driven by the same metabolic engine as obesity and type 2 diabetes, and it affects up to one in three adults, with even higher rates in the Gulf.

Can fatty liver really lead to liver failure?

Yes — and this is the message most patients have never heard. In a significant proportion of people, simple fatty liver progresses to inflammation (steatohepatitis, or MASH), then scarring (fibrosis), then cirrhosis and liver failure. Fatty liver disease has become one of the leading causes of cirrhosis and liver transplantation worldwide, and it is also an important cause of liver cancer. As a liver transplant surgeon, Professor Jamal sees the end of this road — the goal of this article is to keep you off it.

If my liver blood tests are normal, is my liver fine?

No — and this is the most dangerous misconception in fatty liver disease. Liver function tests (ALT, AST) can be completely normal even in patients with significant fibrosis and, at times, established cirrhosis. Blood tests measure liver inflammation at one moment; they do not measure scarring. Do not let anyone reassure you with "your liver tests are normal" if you have risk factors — normal tests do not rule out advanced disease.

What is a FibroScan, and why is it so important?

FibroScan (transient elastography) is a painless, 10-minute scan — like an ultrasound — that measures two things blood tests cannot: how stiff the liver is (stiffness = fibrosis/scarring) and how much fat it contains (CAP score). It is the practical tool for finding the silent patients whose blood tests look fine while scarring is progressing. If you have obesity, type 2 diabetes or fatty liver on ultrasound, ask about a FibroScan.

Who should be checked for fatty liver disease?

Anyone with obesity (especially central obesity), type 2 diabetes or prediabetes, metabolic syndrome, abnormal cholesterol, or fat seen incidentally on an ultrasound. Diabetes deserves special emphasis: people with type 2 diabetes have both a higher chance of having fatty liver and a higher chance of it progressing.

Can fatty liver disease be reversed?

Yes — this is the good news. Liver fat begins to fall with even 5% weight loss; studies suggest losing 7–10% of body weight can resolve inflammation, and sustained major weight loss can allow fibrosis itself to regress. The liver has a remarkable capacity to recover when the metabolic pressure is removed — the challenge is achieving and keeping that weight loss.

How does sleeve gastrectomy help the liver?

Tremendously — bariatric surgery is the most powerful available intervention for fatty liver in patients with obesity. The substantial, sustained weight loss after sleeve gastrectomy resolves steatohepatitis in the majority of patients, allows fibrosis to regress, and dramatically reduces the risk of progressing to cirrhosis. Fatty liver at the crossroads of obesity and liver disease is precisely Professor Jamal's field: he leads KFAS-funded research programs on fatty liver and metabolic surgery — including a collaboration with King's College London — and authored the chapter on sleeve gastrectomy in NASH and liver cirrhosis in an international surgical textbook.

What about weight-loss medications for fatty liver?

Medications such as semaglutide (Wegovy) and tirzepatide (Mounjaro) reduce liver fat and inflammation alongside weight loss, and new liver-targeted medications are emerging. They are valuable options for the right patient — often alongside or after a FibroScan-based assessment. The treatment ladder (lifestyle, medications, endoscopic procedures, surgery) is chosen per patient.

What happens if cirrhosis has already developed?

Cirrhosis needs specialist care: surveillance for liver cancer, management of complications, and in advanced cases liver transplantation — the program Professor Jamal founded in Kuwait with the country's first successful liver transplant in 2018. Selected patients with early cirrhosis can still undergo carefully planned bariatric surgery in expert hands, which is exactly the situation covered in Professor Jamal's published work.

What should I do now?

If you have obesity or diabetes — or you were told you have fatty liver — do not settle for a normal blood test.
