Water intoxication, also known as water poisoning, hyperhydration, overhydration or water toxemia is a potentially fatal disturbance in brain functions that can result when the normal balance of electrolytes in the body is pushed outside safe limits by excessive water intake. Under normal circumstances, accidentally consuming too much water is ...
Polydipsia is excessive thirst or excess drinking. [1] The word derives from the Greek πολυδίψιος ( poludípsios) "very thirsty", [2] which is derived from πολύς ( polús, "much, many") + δίψα ( dípsa, "thirst"). Polydipsia is a nonspecific symptom in various medical disorders. It also occurs as an abnormal behaviour in some ...
Drinking clean water. Medication. Saline. In physiology, dehydration is a lack of total body water, [3] with an accompanying disruption of metabolic processes. It occurs when free water loss exceeds free water intake, usually due to exercise, disease, or high environmental temperature.
Water intoxication. Primary polydipsia and psychogenic polydipsia are forms of polydipsia [1] characterised by excessive fluid intake in the absence of physiological stimuli to drink. [2] Psychogenic polydipsia caused by psychiatric disorders—oftentimes schizophrenia —is frequently accompanied by the sensation of dry mouth.
Mineralcorticoid excess due to a disease state such as Conn's syndrome usually does not lead to hypernatremia unless free water intake is restricted. Salt poisoning is the most common cause in children. It has also been seen in a number of adults with mental health problems. Too much salt can also occur from drinking seawater or soy sauce.
Diuresis (/ ˌ d aɪ j ʊ ˈ r iː s ɪ s /) is the excretion of urine, especially when excessive . The term collectively denotes the physiologic processes underpinning increased urine production by the kidneys during maintenance of fluid balance. In healthy people, the drinking of extra water produces mild diuresis to maintain the body water ...
Fluid balance is an aspect of the homeostasis of organisms in which the amount of water in the organism needs to be controlled, via osmoregulation and behavior, such that the concentrations of electrolytes ( salts in solution) in the various body fluids are kept within healthy ranges. The core principle of fluid balance is that the amount of ...
Cerebral edema is excess accumulation of fluid ( edema) in the intracellular or extracellular spaces of the brain. [1] This typically causes impaired nerve function, increased pressure within the skull, and can eventually lead to direct compression of brain tissue and blood vessels. [1] Symptoms vary based on the location and extent of edema ...
