In the field of medical anomalies, few conditions attract curiosity and concern quite like aquagenic urticaria, commonly known as “water allergy”.
This rare affliction transforms the seemingly innocent act of water contact into a painful ordeal, afflicting people like Loren Montefusco, 22 years old from South Carolina, USA.
Diagnosed with a water allergy, Montefusco’s life is marked by the excruciating sensation of a burning itch deep under her skin. This is triggered by the mere touch of water. Her report reveals the harrowing experiences faced by those who come to grips with this complex condition.
At its core, water allergy is thought to result from an abnormal immune response triggered by the interaction of water with the skin. Think of your immune system as a vigilant guardian, always alert for invaders. In aquagenic urticaria, water somehow triggers an alarm response. This leads to the release of substances such as histamine – causing hives, welts and itching.
Researchers have identified mutations in specific genes associated with water allergy, such as the FABP5 gene, which is essential for skin barrier function. Mutations in this gene impair the skin’s ability to repel water, triggering an inflammatory response.
Variations in genes involved in immune regulation and skin integrity also contribute to susceptibility. However, environmental factors such as hormonal changes or chemical exposure can influence its severity.
Understanding the genetic basis offers insight into how the disease occurs and possible therapies. By identifying specific genetic markers, personalized treatments targeting underlying mechanisms can be developed.
Despite these steps, much about water allergy remains unknown. However, by integrating insights from genetics, immunology and dermatology, scientists aim to unravel the secrets of this rare water allergy, offering hope for better diagnosis and management.
The first documented mention of water allergy dates from the late 20th century, with case reports detailing the puzzling experiences of people afflicted with water-induced hives.
Since then, sporadic cases have dotted medical literature, contributing to our evolving understanding of this disorder. Recent trends suggest a gradual increase in cases, driven by increased awareness among healthcare professionals and improved diagnostic capabilities.
The rarity of water allergy adds to its mystery. Despite its obscurity, the condition leaves an indelible mark on those affected, shaping their experiences in profound and unexpected ways. Current estimates suggest that fewer than 100 cases have been reported worldwide. This underlines its status as one of the rarest types of hives.
Managing this allergy is a huge challenge for patients and healthcare providers alike. These are the strategies used.
Treatments
Conventional allergy treatments (antihistamines, corticosteroids) offer temporary relief but may not address the underlying cause.

Experimental therapies such as phototherapy (exposing the skin to ultraviolet light) try to calm the immune response and reduce inflammation. This therapy has shown some promise in relieving symptoms.
Biologic agents, so-called “large molecular drugs” made of proteins, target specific immune pathways associated with allergic reactions. They offer a more specific therapeutic approach that has potential for long-term symptom management.
Avoiding water is difficult and requires careful planning, including alternative ways to keep clean.
Using protective barriers, such as emollient creams, can help create a layer between the skin and the water, which may help reduce the severity and frequency of symptoms.
Psychological support
Counseling and support groups provide a safe place for people to cope with the emotional difficulties associated with living with a chronic, misunderstood condition like aquagenic urticaria.
Offering coping strategies and building resilience can empower patients to cope better with the uncertainty and stress of their condition, improving overall quality of life.
Further investigation of immune system mechanisms underlying aquagenic urticaria is essential to finding new treatments.
Ongoing clinical trials and studies are essential to evaluate the efficacy and safety of emerging therapies, such as phototherapy and biological agents, in the management of aquagenic urticaria. Unfortunately, the number of patients limits these studies.
