A rising global health issue is slowly but surely advancing in millions: Non-Alcoholic Fatty Liver (NAFL), wherein fat develops in the liver without alcohol use, is being diagnosed more and more in individuals of all ages. Specialists now advise that this "silent" liver ailment may turn into more complicated diseases such as non-alcoholic steatohepatitis (NASH), liver fibrosis, and even liver failure if left ignored. From data by The Lancet Regional Health – Western Pacific and news reported by The Guardian (June 2025), more than 423 million individuals in the 15-to-39 age group had NAFLD in 2021—a staggering 75% rise from 1990. The World Health Organisation (WHO) and the U.S. National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) also indicate that approximately 30–38% of the world's adults might now be suffering from some type of fatty liver disease. Physicians classify NAFL as a "silent" liver condition since it usually presents no symptoms. The first symptoms, though, may be unexplained fatigue, vague discomfort in the upper-right abdomen, increased liver enzymes, or dark spots on the skin (a condition called acanthosis nigricans). Diagnosis is usually made by routine blood work, ultrasounds, or MRIs, and occasionally, a liver biopsy. Physicians emphasise that lifestyle modifications are the only established treatment for NAFL. These are: -Losing 5–10% body weight -Eating a liver-friendly diet with fruits, vegetables, lean meats, and whole grains -Staying away from added sugars and processed foods -Regular exercise, even just daily walks -Controlling conditions such as diabetes and high cholesterol Health systems around the world are lagging behind. Few general practitioners are equipped to diagnose NAFL in the early stages, and there is no formal screening procedure in most countries. As reported by The Guardian, a mere 18% of individuals suffering from fatty liver disease get an accurate diagnosis before severe damage occurs. Some promising therapies—namely, GLP-1 receptor agonists such as semaglutide and tirzepatide—are in testing now, with initial success in decreasing liver fat as well as inflammation. But these are not yet prevalent or affordable for the majority. Physicians and scientists call for early screening in people with obesity, diabetes, insulin resistance, or a family history of liver disease. Increased awareness, enhanced access to liver health care, and preventive care are critical to combating this emerging public health problem.
