Weight Loss Overview

Losing weight is not really a medical symptom if it is explained by lifestyle changes. That means you’re eating less, eating better foods, or exercising more. Changes to appetite can also cause weight loss, and can be the cause of disease (see “poor appetite”). Another common cause would be various infections, such as a virus, which lead to weight loss during the illness, but there are usually other symptoms such as fever. If none of these is the case, or if the weight loss is sudden, then it is “unexplained weight loss”. Unexplained weight loss can be the symptom of a variety of disorders, such as diabetes, thyroid disease, and various others. See your doctor for a diagnosis of unexplained weight loss.
