Strange Medical Conditions You Won’t Believe Are Real

Aquagenic Urticaria

Aquagenic urticaria, more commonly known as an allergy to water, is a rare allergy causing hives or red welts upon contact with water. In most cases, the rash develops on the neck, upper torso, and arms, lasting thirty minutes to an hour after the water has been removed. There is not enough evidence to determine an exact cause of aquagenic urticaria. However, medical professionals have suggested two theories: dissolved chemicals or substances in the water trigger an allergic reaction, or the mixture of water and a dissolved substance is the cause of the allergy.

The typical treatments for aquagenic urticaria include antihistamines, stanozolol, creams acting as a barrier between skin and water, Ultraviolet B light treatments, and a bath with sodium bicarbonate.
