which can be considered the real reasons for malnutrition
Malnutrition Undernourishment is most often due to not enough high-quality food being available to eat.[5] This is often related to high food prices and poverty.[1][5] A lack of breastfeeding may contribute, as may a number of infectious diseases such as: gastroenteritis, pneumonia, malaria, and measles, which increase nutrient requirements.[5] There are two main types of undernutrition: protein-energy malnutrition and dietary deficiencies.[12] Protein-energy malnutrition has two severe forms: marasmus (a lack of protein and calories) and kwashiorkor (a lack of just protein).[2] Common micronutrient deficiencies include: a lack of iron, iodine, and vitamin A.[2] During pregnancy, due to the body's increased need, deficiencies may become more common.[13] In some developing countries, overnutrition in the form of obesity is beginning to present within the same communities as undernutrition.[14] Other causes of malnutrition include anorexia nervosa and bariatric surgery.[15][16]
