Asthma
Asthma is a chronic (long-term) lung condition. Air passages narrow and become inflamed.
Who Is At Risk?
More than 100 million people worldwide have asthma.
Overview
A chronic condition of the lungs, asthma occurs when inflammation causes airways to narrow, resulting in wheezing, coughing, difficulty breathing and chest tightness.

What Triggers An Attack?
Allergies And Airborne Irritants

An allergic reaction or response to fumes, perfumes, smoke or other irritants in the air may trigger an asthma attack.

Exercise

Strenuous activity also can trigger what's known as "exercise-induced asthma."

Weather Conditions

Abrupt changes in the weather can cause prolonged asthma attacks.

Viruses

N/D

Drugs And Medications

About 10 percent of all asthma patients are sensitive to aspirin and other anti-inflammatory pain medications, such as ibuprofen.

Sulfites

Some chemicals found in commercially prepared foods can also set off asthma attacks.

Stomach Reflux

Stomach reflux -- when stomach acids back up into your esophagus-can cause asthma attacks.

Stress

Strong emotional feelings can lead to a change in breathing patterns.

Types Of Asthma
Adult-Onset Asthma

When asthma first develops after age 20, women are much more likely to be affected by adult asthma than men.

Nocturnal Asthma

Asthma symptoms are often more intense at night - typically between midnight and early morning, when lung function is at its worst in many people with asthma.

Exercise-Induced Asthma

Some people develop asthma attacks only as a reaction to exercise, and about 90% of all people with asthma are susceptible to attacks brought on by exercise or participating in sports.

Occupational Asthma

You can develop asthma in response to chemicals or allergens to which you are exposed at work.

Asthma in the Elderly

"More than 1 million American adults older than age 65 have already been diagnosed with asthma, but the number of seniors with this condition is no doubt much higher."
