Nonalcoholic Fatty Liver Disease (NAFLD/MASLD): Overview, Diagnosis, and Treatment
Nonalcoholic fatty liver disease, now increasingly called MASLD, affects roughly a third of the world's adult population according to recent meta-analyses — yet most people don't know they have it, since the disease is typically silent for years. We explain how it's diagnosed, why it progresses to more serious liver inflammation (NASH/MASH) in some patients, and why weight loss remains the first-line treatment.
