Unintentional weight loss is common among older adults and is associated with significant adverse health outcomes, increased mortality, and progressive disability. The diagnosis is often associated with an underlying illness; however, in as many as one in four older adults with unintentional weight loss, no obvious medical cause can be identified. A variety of nonpharmacologic interventions may improve energy intake and lead to weight gain. The most common approach to the treatment of weight loss among older adults is consumption of high-energy/protein oral supplements between meals as a means of increasing daily energy intake. Involving other health professionals, including a dietitian, may be helpful in the assessment and management plan. In addition, a number of pharmacologic treatments have been investigated, but the potential benefit of these treatments remains unclear.
Key words: weight loss, older adults, malnutrition, oral nutritional supplementation, megestrol.
