Anorexia and weight loss in the elderly. Causes range from loose dentures to debilitating illness.
Differentiating between anorexia (loss of appetite) and weight loss (documented loss of pounds) can be difficult, but the same causes and treatments apply to both. Gastrointestinal and metabolic disorders, cardiopulmonary disease, the presence of a neoplasm or infection, and use of certain drugs are possible medical causes. Inadequate nutritional intake can result from the inability to obtain and prepare foods, dietary restrictions, intolerance to certain foods, and poor oral and dental health. Social factors that can greatly reduce an elderly person's interest in food include loneliness, depression, isolation, and self-consciousness because of hearing and visual impairments. Some problems, such as alcohol abuse or inappropriate use of certain medications, may be revealed only with difficulty, and some of the problems mentioned may overlap. Although the physician may find assessment of anorexia or weight loss in the elderly a challenge, it usually responds well to corrective measures.
