Malnutrition occurs when an organism gets too few or too many nutrients, resulting in health problems. [11] [12] Specifically, it is a deficiency, excess, or imbalance of energy, protein and other nutrients which adversely affects the body's tissues and form. [13] Malnutrition is a category of diseases that includes undernutrition and ...
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.
Malnutrition and its consequences are large contributors to deaths, physical deformities, and disabilities worldwide. [3] Good nutrition is necessary for children to grow physically and mentally, and for normal human biological development.
Failure to obtain the required amount of nutrients causes malnutrition. Nutritional science is the study of nutrition, though it typically emphasizes human nutrition. The type of organism determines what nutrients it needs and how it obtains them.
Malnutrition can affect the pharmacokinetics of various drugs used to treat PRDs by changing a drug's bioavailability, distribution, and elimination. [38] To optimize the treatment of those diseases, there needs to be more research into how severe malnutrition, specifically kwashiorkor, can affect treatment response.
Impaired calcium and vitamin D absorption and chelation of calcium by unabsorbed fatty acids resulting in fecal loss of calcium may all contribute. If calcium deficiency is prolonged, secondary hyperparathyroidism may develop. Prolonged malnutrition may induce amenorrhea, infertility, and impotence.
Stunted growth, also known as stunting or linear growth failure, is defined as impaired growth and development manifested by low height-for-age. [1] It is often caused by malnutrition and can occur due to endogenous factors (such as chronic food insecurity) or exogenous factors (such as parasitic infection).
Malnutrition often results in many diseases and health concerns that require immediate medical attention. Of these side effects, there is an emphasis on addressing the increased risk of hypoglycemia, hypothermia, cardiac failure, and the likelihood of missing the presence of an infection.
