What is Dermatographia, the Skin Condition That Causes Itchy Red Swells?

Causes of Dermatographia

The exact cause of dermatographia is not well understood. However, it has been linked to some illnesses and conditions such as hay fever, asthma, stress, medications, food allergies, and viral infections. It is also more common in women than in men.

Symptoms of Dermatographia

The main symptom of dermatographia is the development of welts or bumps on the skin when it is lightly scratched or rubbed. The welts, which can be red and itchy, generally disappear within 30 minutes or so. In addition, people with dermatographia may also experience mild to moderate itching.

Treatment for Dermatographia

Treatment for dermatographia is largely done to alleviate the symptoms. This includes using cold compresses and antihistamines to reduce the itching and taking anti-inflammatories to reduce the swelling. In some cases, doctors may recommend medications or avoid triggers that could worsen symptoms. These may include stress or certain foods.

Prevention of Dermatographia

Because the cause of dermatographia is largely unknown, prevention is difficult. However, taking steps to reduce stress, avoiding food triggers, and avoiding medications that could worsen the condition can help to control the symptoms. In addition, avoiding repetitive skin pushing or pulling can help to prevent flare-ups. For people with severe skin conditions, a visit to a skin doctor may be helpful in tracking symptoms and determining the best course of action.
