Unintentional weight loss
When the body mass starts decreasing even if the person is not trying to lose weight, it is termed unintentional weight loss. It can be due to a pathological process, a direct or side effect of an underlying illness. Weight is regulated by metabolic processes. Disorders that involve hormones of metabolism can cause fluctuation in weight. Some conditions that impair social and mental abilities can also cause poor appetite and weight loss. Unintentional weight loss is a common problem in people above the age of 65. It is best to visit your doctor if you start noticing a significant weight change. [3]
