When metabolic needs cannot be met due to lack of food, the body initially uses carbohydrates rather than protein or fat to meet metabolic needs. Backup reserves of carbohydrates are stored in the liver in small amounts. These reserves may be totally depleted within 18 hours of continuous use. Once this is gone, protein will then be used. Protein is first converted to glucose for energy. Within 5 to 9 days, the body will rely solely on body fat to supply needed energy.

There is a wide variety of causes of malnutrition. An elderly person with dementia may forget to eat or to buy food. Poverty may cause a lack of food or lack of nutritious food. People in third world countries often do not have access to healthy foods. Other causes may be alcoholism, excessive dieting, throat or mouth cancer, decreased mobility, malabsorption, dialysis, fistulas, corticosteroid or oral antibiotic use, hypermetabolism, burns, trauma, or a lack of oral intake for 5-10 days for a variety of reasons.

Incidence of malnutrition in America is low, thought to be as low as 10% nationwide. Death from malnutrition in our country is extremely rare. Worldwide death from malnutrition among children under age 5 is thought to be as high as 50%.

Prognosis is very good for patients with malnutrition in America. Most incidents are temporary and are a result of another condition. The malnutrition is very treatable with food, nutritional supplements such as Ensure, or parental feedings depending on the cause.
