In living organisms, starvation is a severe reduction in vitamin, nutrient, and energy intake, and is the most extreme form of malnutrition. In humans, prolonged starvation (in excess of 1-2 months) causes permanent organ damage, and may eventually result in death.
Starved individuals lose substantial fat and muscle mass as the body turns to these tissues for energy. The skin's pale and dry appearance attenuates this emaciation.
Vitamin deficiency is common, often resulting in beriberi, pellagra, and scurvy. These diseases collectively may cause diarrhea, skin rashes, edemaEdema ( BE: oedema formerly known as dropsy is swelling of any organ or tissue due to accumulation of excess fluid. Edema has many root causes, but its common mechanism is accumulation of fluid into the tissues. Types of edema are pitting edema and non-pi, and heart failure. RiboflavinRiboflavin E101 , also known as vitamin B is an easily absorbed, water-soluble micronutrient with a key role in maintaining human health. Like the other B vitamins, it supports energy production by aiding in the metabolising of fats, carbohydrates, and pr deficiency causes anemiaThis article discusses the medical condition. For the fern genus, see Anemia (fern . Anemia ( American English) or anaemia ( British English) is a lack of red blood cells and/or hemoglobin. This results in a reduced ability of blood to transfer oxygen to. Individuals are often irritable, fatigueIn Wikipedia, fatigue can mean: # Fatigue (physical) tiredness in humans # Fatigue (material) failure by repeated stress in materials # Fatigues (uniform) military uniform # Battle fatigue also known as Post-traumatic stress disorder # Reader's fatigue #d, and lethargic as a result.
Starvation is usually treated by slowly increasing food intake until no nutrient deficiencies remain. By this time, the diet of a recovering individual should consist of 5,000 calorieIn physics, a calorie (abbreviated cal is a unit of energy that equals the amount of heat necessary to raise the temperature of one gram of water by 1 degree Celsius, at a pressure of 1 atm. This amount of heat depends somewhat on the initial temperatures and twice the Recommended Dietary AllowanceFood and drink Vitamins Recommended Dietary Allowance (RDA) is the daily dietary intake level of a nutrient that is considered sufficient to meet the requirements of nearly all (97-98%) healthy individuals in each life-stage and gender group. The RDAs are (RDA) of nutrients.
