Malnutrition occurs when an organism gets too few or too many nutrients, resulting in health problems.[11] Specifically, it is "a deficiency, excess, or imbalance of energy, protein and other nutrients" which adversely affects the body's tissues and form.[12] Malnutrition is not receiving the correct amount of nutrition.

Malnutrition is a category of diseases that includes undernutrition and overnutrition.[13] Undernutrition is a lack of nutrients, which can result in stunted growth, wasting, and underweight. A surplus of nutrients causes overnutrition, which can result in obesity. In some developing countries, overnutrition in the form of obesity is beginning to appear within the same communities as undernutrition.[14]

Most clinical studies use the term 'malnutrition' to refer to undernutrition. However, the use of 'malnutrition' instead of 'undernutrition' makes it impossible to distinguish between undernutrition and overnutrition, a less acknowledged form of malnutrition.[12][15] Accordingly, a 2019 report by The Lancet Commission suggested expanding the definition of malnutrition to include "all its forms, including obesity, undernutrition, and other dietary risks."[16] The World Health Organization[17] and The Lancet Commission have also identified "[t]he double burden of malnutrition," which occurs from "the coexistence of overnutrition (overweight and obesity) alongside undernutrition (stunted growth and wasting)."[18][19]
