Drinking too much water can be poisonous.

Artunc F, Schnauder G, Gallwitz B, Amend B. [Can water be poisonous?]. Deutsche medizinische Wochenschrift. 2015 Nov;140(23):1761. doi: 10.1055/s-0041-105886. [Article in German]

HISTORY AND ADMISSION FINDINGS: Two female patients aged over 80 years developed central nervous symptoms after drinking large amounts of water (more than 3 l per day).

INVESTIGATIONS: Both had a hypoosmolar hyponatremia that was induced by concomitant treatment with hydrochlorothiazid (HCT) in the one case and in the other case relied on a distal tubular damage due to reflux nephropathy.

DIAGNOSIS, TREATMENT AND COURSE: Hyponatremia was corrected after withdrawal of HCT and fluid restriction and central nervous symptoms disappeared rapidly.

CONCLUSIONS: Distal tubular urinary dilution can be disturbed by HCT and parenchymal renal disease and can result in symptomatic hyponatremia after drinking large amounts of water.

“Water poisoning” cause of death for canoist

A Texas Water Safari paddler died Monday of too much water inside his body. A condition known as “Hyponatremia”, the electolytes in the body become too imbalanced to sustain life due to consumption of too much drinking water. Click here….

Hyponatremia: drinking too much water can kill you

Too much water consumed quickly can cause hyponatremia….fatalities from this condition are reported at least a few times every year. Click here for examples from California (land of the friuts and nuts) of what can happen…..

European Commission: Drinking water does NOT prevent dehydration?

This is what bureaucrats in government do well….click here. Does this apply to tap water as well? At first read, this looks like a silly ruling….

But it seems like there is confusion over the exact basis for the commission’s ruling….click here for the ruling itself. An attempted clarification has been posted (click here), but even after reading this, the basis of the ruling is still not clear…..It looks like the intent is to prevent misleading or false advertising (and not to make a health determination), and if so then a clear explanation of the basis should be provided to avoid confusion…..

Hyponatremia…..Too Much Water can be Fatal

Exercise-associated hyponatremia (EAH) is hyponatremia that occurs <or= 24 hours after prolonged physical activity. It is a potentially serious complication of marathons, triathlons, and ultradistance events, and can occur in hot and cold environments. Clear evidence indicates that EAH is a dilutional hyponatremia caused by excessive fluid consumption and the inappropriate release of arginine vasopressin. Cerebral and pulmonary edema can cause serious signs and symptoms, including altered mental status, respiratory distress, seizures, coma, and death. Rapid diagnosis and urgent treatment with hypertonic saline is necessary to prevent severe complications or death. Prevention is based on educating athletes to avoid excessive drinking before, during, and after exercise.
