Kwashiorkor is a severe form of malnutrition associated with a deficiency in dietary protein. Both clinical subtypes of severe acute malnutrition (kwashiorkor and marasmus) are treated similarly. The bloated stomach represents a form of malnutrition called kwashiorkor. Children suffered from kwashiorkor which came from malnutrition and the adults struggled to survive. Children with kwashiorkor often develop irritability and anorexia. A similar disorder, seen in very young malnourished children, is kwashiorkor. Kwashiorkor is distinguished from marasmus by the presence of edema. Kwashiorkor cases occur in areas of famine or poor food supply. Kwashiorkor and marasmus are childhood disorders caused by lack of dietary protein. The precise etiology of kwashiorkor remains unclear. Kwashiorkor is mainly caused by inadequate protein intake. It is deprived enough for the poorer inhabitants to have kwashiorkor, or protein deprivation. Two forms of PEM are kwashiorkor and marasmus, and they commonly coexist. PEM can appear as conditions called marasmus, kwashiorkor, and an intermediate state of marasmus-kwashiorkor.
