An English woman developed an allergy to water after giving birth that is so severe she can't even go out in the rain and is only able to drink Diet Coke, the Daily Mail reports.

Michaela Dutton, 21, developed a condition known as aquagenic urticaria after giving birth to her now 3-year-old son, Mitchell.

The condition, which is also known as water urticaria and aquagenous urticaria, affects just 1 in 230 million people worldwide and causes hives to flare up on the skin within 15 minutes of coming into contact with water. The hives can last for several hours.

Although it is considered an allergy, it is not a histamine-related allergy like most other allergies, which means that antihistamines such as Benadryl do not work to prevent or control symptoms.

Dutton is unable to drink tea, coffee or fruit juice because they make her throat blister and swell up, according to the Daily Mail.

She survives on Diet Coke, which her body tolerates, even though it contains carbonated water. Even coming into contact with her son's tears or sweat makes her swell up.

Because of the water allergy, she jumps into the shower for just 10 seconds a week. The rest of the time she wipes herself down with a cloth.
