A study on the relationship between malnutrition and other conditions in the elderly found that malnutrition in the elderly can result from gastrointestinal and endocrine system disorders, loss of taste and smell, decreased appetite and inadequate dietary intake. Poor dental health, ill-fitting dentures, or chewing and swallowing problems can make eating difficult. As a result of these factors, malnutrition is seen to develop more easily in the elderly.Rates of malnutrition tend to increase with age with less than 10 percent of the "young" elderly (up to age 75) malnourished, while 30 to 65 percent of the elderly in home care, long-term care facilities, or acute hospitals are malnourished. Many elderly people require assistance in eating, which may contribute to malnutrition. However, the mortality rate due to undernourishment may be reduced. Because of this, one of the main requirements of elderly care is to provide an adequate diet and all essential nutrients. Providing the different nutrients such as protein and energy keeps even small but consistent weight gain. Hospital admissions for malnutrition in the United Kingdom have been related to insufficient social care, where vulnerable people at home or in care homes are not helped to eat.In Australia malnutrition or risk of malnutrition occurs in 80 percent of elderly people presented to hospitals for admission. Malnutrition and weight loss can contribute to sarcopenia with loss of lean body mass and muscle function. Abdominal obesity or weight loss coupled with sarcopenia lead to immobility, skeletal disorders, insulin resistance, hypertension, atherosclerosis, and metabolic disorders.
Compensatory mechanism for metabolic alkalosis involve slowed breathing by the lungs to increase serum carbon dioxide, a condition leaning toward respiratory acidosis. As respiratory acidosis often accompanies the compensation for metabolic alkalosis, and vice versa, a delicate balance is created between these two conditions. See also
