Aquagenic urticaria
Aquagenic Urticaria
Aquagenic urticaria (pronounced: ah-kwa-jen-ic ur-ti-care-ia), also known as water allergy or water urticaria, is a rare form of urticaria, a type of hives that appear after the skin comes into contact with water, regardless of its temperature.
Etymology
The term "Aquagenic" is derived from the Latin words 'aqua' meaning water and 'genic' meaning producing or caused by. "Urticaria" is derived from the Latin word 'urtica', meaning nettle, a plant known to cause itchy skin when touched.
Symptoms
Symptoms of aquagenic urticaria include redness, itching, and swelling of the skin after exposure to water. These symptoms usually appear within 30 minutes of exposure and can last for an hour or more. In severe cases, drinking water can cause swelling of the throat and difficulty swallowing, known as angioedema.
Causes
The exact cause of aquagenic urticaria is unknown. However, it is believed to be caused by an allergic reaction to a substance in the water, rather than the water itself. Some researchers suggest that it may be related to the presence of additives or chemicals in the water, such as chlorine.
Treatment
Treatment for aquagenic urticaria typically involves avoiding contact with water as much as possible. Antihistamines may be used to help manage symptoms. In severe cases, a dermatologist may recommend phototherapy, a treatment that uses light to treat skin conditions.
