Detailed explanation-1: -Water intoxication, also known as dilutional hyponatremia, develops only because the intake of water exceeds the kidney’s ability to eliminate water. Causes of this water intoxication include psychiatric disorder, forced water intake as a form of child abuse and iatrogenic infusion of excessive hypotonic fluid.
Detailed explanation-2: -Hypovolemic hyponatremia: In this situation, the total body water decrease is bigger than the decrease in total body sodium. Dilutional hyponatremia: This type of low blood sodium is also called “water intoxication.”
Detailed explanation-3: -Classification of Hyponatremia Dilutional hyponatremia has two primary classifications: normal extracellular volume (euvolemic) or elevated extracellular volume (hypervolemic). Euvolemic hyponatremia is defined by a serum osmolarity of <270mosm/l and a urine osmolarity of 100mosm/l.
Detailed explanation-4: -What causes hyponatremia? A low sodium level in your blood may be caused by too much water or fluid in the body. This “watering down” effect makes the amount of sodium seem low. Low blood sodium can also be due to losing sodium from the body or losing both sodium and fluid from the body.
