Dermatographia (Dermatographism)

Overview

Dermatographia is a common, benign (not harmful) skin condition. It causes you to develop raised marks (wheals) or a reaction similar to hives when you scratch your skin. Pressure or rubbing (friction) may also cause a reaction.

Dermatographism, dermatographic urticaria and skin writing are other names for dermatographia.

Who does dermatographia affect?

Dermatographia can affect anyone. However, you may be more likely to have dermatographia if:

You’re a teenager or in your 20s.
You have dry skin.
You have dermatitis.

You may also be more likely to have dermatographia if someone else in your family has it.

How common is dermatographia?

Dermatographia is common. It affects about 2% to 5% of the general population.

How does dermatographia affect my body?

Dermatographia welts don’t hurt, but they can be itchy. However, you may feel self-conscious or uncomfortable until it fades, usually after about 30 minutes.

Complications

Blood clots are a dangerous complication of atrial fibrillation (AFib). Blood clots can lead to stroke.

The risk of stroke from AFib increases as you grow older. Other health conditions also may increase the risk of a stroke due to AFib. These conditions include:

High blood pressure.
Diabetes.
Heart failure.
Some types of heart valve disease.

Blood thinners are commonly prescribed to prevent blood clots and strokes in people with atrial fibrillation.

Prevention

Healthy lifestyle choices can reduce the risk of heart disease and may prevent atrial fibrillation (AFib). Here are some basic heart-healthy tips:

Control high blood pressure, high cholesterol and diabetes.
Don't smoke or use tobacco.
Eat a diet that's low in salt and saturated fat.
Exercise at least 30 minutes a day on most days of the week unless your health care team says not to.
Get good sleep. Adults should aim for 7 to 9 hours daily.
Maintain a healthy weight.
Reduce and manage stress.
