Unintentional weight loss is defined as a notable decline in body weight that happens even when the individual is not attempting to reduce weight. Diet, exercise, and lifestyle modifications do not result in weight reduction. Weight reduction of 10 pounds or more, or 5% of body weight, during a 6- to 12-month period is termed “unintentional.”
Anyone may have unintentional weight loss. It is, however, most frequent and most dangerous in adults over the age of 65. It may be caused by disorders ranging from moderate to severe, including prescription medicine side effects, cancer, depression, diabetes. It can also be due to Addison’s disease, Celiac disease, pancreatic enlargement, and dementia. Even unexplained weight loss of less than 5% of total weight, or 10 pounds, may indicate a dangerous condition in the elderly.
