Protein–energy undernutrition (PEU), once called protein–energy malnutrition (PEM), is a form of malnutrition that is defined as a range of conditions arising from coincident lack of dietary protein and/or energy in varying proportions. The condition has mild, moderate, and severe degrees.
As a result of these factors, malnutrition is seen to develop more easily in the elderly. [224] 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.

This is an extreme example of how malnutrition can result in hypoalbuminemia. [3] More typical is malnutrition-associated hypoalbuminemia in the elderly, who appear thin and frail but not with the rounded abdomen and edema seen in Kwashiorkor. Albumin is an acute negative phase respondent and not a reliable indicator of nutrition status.
Kwashiorkor is a type of severe acute malnutrition (SAM). SAM is a category, composed of two conditions: marasmus and kwashiorkor. [9] Both kwashiorkor and marasmus fall under the umbrella of protein–energy malnutrition (PEM). [10]
SBS patients often suffer from malnutrition, severe diarrhea, dehydration, fatigue, osteopenia, and weight loss due to the reduced intestinal capacity to absorb nutrients, water, and electrolytes.
Tea and toast syndrome is a form of malnutrition commonly experienced by elderly people who cannot prepare meals and tend to themselves. The term is not intrinsic to tea or bread products only; rather, it describes limited dietary patterns that lead to reduced calories resulting in a deficiency of vitamins and other nutrients.
When too much food or liquid nutrition supplement is consumed during the initial four to seven days following a malnutrition event, the production of glycogen, fat and protein in cells may cause low serum concentrations of potassium, magnesium and phosphate.
The Malnutrition Screening Tool (MST) is a validated malnutrition screening tool that is primarily used in the residential aged care facility or for adults in the inpatient/outpatient hospital setting. It includes parameters such as weight loss and appetite. [18] Disability-adjusted life year for protein-energy malnutrition per 100,000 ...
