Starvation is a severe deficiency in caloric energy intake, below the level needed to maintain an organism's life. It is the most extreme form of malnutrition. In humans, prolonged starvation can cause permanent organ damage [1] and eventually, death. The term inanition [2] refers to the symptoms and effects of starvation.
This state can be either physiologic or pathologic; physiologic ketotic hypoglycemia is a common cause of hypoglycemia in children, often in response to stressors such as infection or fasting. [1] Pathologic ketotic hypoglycemia is typically caused by metabolic defects, such as glycogen storage disorders. [2]
Starvation response in animals (including humans) is a set of adaptive biochemical and physiological changes, triggered by lack of food or extreme weight loss, in which the body seeks to conserve energy by reducing metabolic rate and/or non-resting energy expenditure to prolong survival and preserve body fat and lean mass.
Body mass is large enough to make starvation hypoglycemia and idiopathic ketotic hypoglycemia quite uncommon. Recurrent mild hypoglycemia may fit a reactive hypoglycemia pattern, but this is also the peak age for idiopathic postprandial syndrome , and recurrent "spells" in this age group can be traced to orthostatic hypotension or ...
Prolonged fasting (also called extended fasting or water fasting) involves periods of fasting above 24 hours, typically in the range of 5–20 days. [13] In early fasting, the body operates under a relatively high level of gluconeogenesis , though this eventually decreases as the body's metabolism switches into ketosis , causing ketones to ...
Another estimate, also by WHO, states that childhood underweight is the cause for about 35% of all deaths of children under the age of five worldwide. [ 6 ] The main causes of malnutrition are often related to poverty : unsafe water, inadequate sanitation or insufficient hygiene , factors related to society, diseases, maternal factors, gender ...
Hunger is a sensation that motivates the consumption of food. The sensation of hunger typically manifests after only a few hours without eating and is generally considered to be unpleasant. Satiety occurs between 5 and 20 minutes after eating. [1] There are several theories about how the feeling of hunger arises. [2]
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 a manifestation of malnutrition (undernutrition) and can be caused by endogenous factors (such as chronic food insecurity) or exogenous factors (such as parasitic infection).
