What is "water intoxication"?
"Water intoxication", also known as dilutional hyponatremia, refers to when the total amount of water ingested by the body greatly exceeds the amount of water discharged, resulting in water retention in the body, resulting in a decrease in plasma osmotic pressure and an increase in circulating blood volume.
However, when there is "water intoxication", the concentration of sodium ions outside the cells is lower than that inside the cells. In order to maintain the concentration balance inside and outside the cells, the water outside the cells will flow into the cells, causing the cells to swell.
If the brain cells swell, because the brain is fixed and wrapped by the hard skull, the brain tissue is squeezed, which may cause cerebral edema, headache, drowsiness, blurred vision and other symptoms, and may even be fatal in severe cases.
