Exercise-Induced Asthma

Overview

Exercise-induced asthma happens when your airways get smaller during exercise, making it hard for you to breathe. You may have asthma symptoms like coughing, wheezing and shortness of breath during or after physical activity.

Symptoms can be worse when the air is cold and dry, or when pollution levels and pollen counts are high. Exercise-induced asthma is also called exercise-induced bronchoconstriction (EIB) or sports-induced asthma.

How common is exercise-induced asthma?

About 40% to 90% of people with asthma have symptoms during or after exercise. But it can happen even without an asthma diagnosis — up to 20% of people in the general population (who may or may not have asthma) have exercise-induced asthma symptoms.

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.
