Think fatty liver only affects people who drink alcohol? Think again! The condition can develop even in people who have never touched alcohol, often without any obvious symptoms. Factors such as diabetes , belly fat, high cholesterol and insulin resistance can contribute to fat building up in the liver.
In an interview with HT Lifestyle, Dr Vineet Kumar Gupta, Senior Director and Unit Head, Gastroenterology, ShardaCare – Healthcity, explains why fatty liver should not be ignored, who is at risk and how early detection and lifestyle changes can help protect liver health.

When the body becomes resistant to insulin, fat can accumulate in liver cells. Sugary drinks, refined carbohydrates and physical inactivity can also contribute. “Fatty liver is not just a concern for people who consume alcohol or those who are overweight. Even individuals with a normal body weight can develop the condition, particularly if they have insulin resistance or other metabolic risk factors. In some people, fat accumulation triggers inflammation, leading to metabolic dysfunction-associated steatohepatitis (MASH). Persistent inflammation can cause fibrosis, or liver scarring, which may progress to cirrhosis and, in some cases, liver cancer. Cardiovascular disease is also a major concern among people with MASLD.
Known as metabolic dysfunction-associated steatotic liver disease (MASLD), the condition affects an estimated 30% of adults worldwide, according to a 2023 analysis published in Hepatology. People with type 2 diabetes , high triglycerides, high blood pressure or excess weight are at greater risk. Because treatment needs to address the factors contributing to fat accumulation in the liver,” explains Dr Gupta, identifying the underlying cause is important.
People with diabetes, high cholesterol, high blood pressure, abdominal obesity or a family history of metabolic disease should discuss liver health with their doctor. Evaluation may also be needed if liver enzymes remain elevated or fatty liver is detected during imaging. Understanding your risk factors, getting evaluated when necessary and following the right treatment plan can help detect fatty liver early and protect your long-term liver health,” concludes Dr Gupta.

Because you do not drink alcohol or feel completely well, “Do not assume that your liver is healthy simply.
Doctors may use the FIB-4 score, based on age and routine blood test results, to assess the risk of advanced fibrosis. Because symptoms may not appear until the condition has progressed, “Fatty liver can remain undetected for years. “Not everyone with fatty liver will develop serious liver disease, but the risk increases when inflammation and scarring occur. This is why assessing the extent of liver damage is important. Fatty liver often causes no symptoms in its early stages. It may be discovered during an ultrasound or through blood tests showing elevated liver enzymes. However, normal liver enzyme levels do not rule out liver disease or significant scarring. A FibroScan may be recommended for further evaluation. Normal liver enzyme levels do not always mean that the liver is healthy. People with diabetes, obesity or other metabolic risk factors should discuss appropriate screening with their doctor, particularly when there are concerns about liver damage,” explains Dr Gupta. “Lifestyle changes can make a significant difference to liver health. Regular exercise, a balanced diet and effective control of diabetes, cholesterol and blood pressure are important parts of treatment. The goal is to adopt sustainable habits that improve metabolic health and reduce liver fat over time,” advises Dr Gupta. “Treatment should be tailored to the individual, depending on the extent of liver damage and the presence of other health conditions. Some patients may benefit from specific medications alongside lifestyle changes, while others may primarily need metabolic risk management and regular follow-up.
Identifying fibrosis early helps doctors determine who needs closer monitoring and more intensive treatment,” says Dr Gupta. Taking supplements without medical guidance can sometimes cause additional harm,” says Dr Gupta.
