Foods - Water - Contraindications / Precautions / Warnings

Excessively high levels of water intake can disrupt sodium and potassium ion function in the body and lead to convulsions, coma, and death. This situation may occur with people suffering from psychogenic polydipsia (a psychiatric disorder), or those who have had severe head injuries or lung tumours.

People practicing fad weight-loss diets are also more susceptible to drinking vast quantities of fluid and should exercise caution.
