Asthma is a chronic condition in which your airways narrow and swell and produce extra mucus. This makes breathing difficult and triggers coughing, wheezing and shortness of breath. For some people, asthma is a minor nuisance. For others, it can be a major problem that interferes with daily activities and may lead to a life-threatening asthma attack.
A period of intense difficulty breathing is called an "asthmatic attack" or "asthma flare-up." This can happen when airways are exposed to and react to triggers (allergens and irritants). The following changes occur:
Asthma typically begins in childhood, but it can begin at any age and often continues into adulthood and even old age. The intensity and severity of asthma symptoms varies broadly from patient to patient, and may change over time.
Pulmonologists at Brigham and Women's Hospital Lung Center work closely with Brigham allergists and the Mass General Brigham Asthma Center, a collaboration among healthcare providers of the Mass General Brigham system. Mass General Brigham Asthma Center specialists are experts in diagnosing asthma, identifying triggers, establishing a treatment plan and managing symptoms to improve adult patients' long-term quality of life.
Special services include management of difficult-to-control asthma, occupational asthma and asthma among pregnant women. The specialists at the Mass General Brigham Asthma Center have been treating patients with asthma for more than 25 years and have developed valuable resources for helping patients control their disease.
All physicians at Mass General Brigham Asthma Center are board certified and are faculty members at Harvard Medical School.
Although the exact cause of asthma is unknown, it is believed to be due to a combination of genetic (inherited) and environmental factors. Many patients with asthma have other allergic diseases, including allergic rhinitis and conjunctivitis ("hay fever") and atopic dermatitis (eczema).
Asthma is most common in:
Other factors include the following:

To diagnose asthma, your physician will examine your chest, measure your lung function, and conduct tests to rule out other possible lung disorders. Your physician will also ask you questions about your symptoms and family history of asthma and allergies.
In addition, your physician will inquire about the frequency with which you experience asthmatic symptoms and the intensity of your symptoms. This will help your physician to determine your asthma's severity and develop an effective plan for treating and managing your symptoms.
Spirometry: Spirometry is an important test to determine your lung function. The spirometer measures the amount of air you breathe out and how quickly you can exhale all the air from your lungs.

In addition to spirometry, your physician may also conduct
Although there is no cure for asthma, it can be effectively managed. You and your health care team will work together to develop a plan to:
Your management plan will include medications (see below), exercises, emotional support and strategies for avoiding triggers. The plan will depend on your asthma triggers, the severity of your symptoms, your age and other factors. It is important to meet with your doctor on a regular basis to review your plan and make modifications if necessary.

Asthma is treated with both long-term and quick-relief medications.
Long-term medications reduce inflammation and prevent symptoms from starting in the first place, but they cannot stop a flare-up in progress.
Quick-relief medications relieve asthma symptoms when they become more intense. Be sure to carry your quick-relief medication with you at all times and take the medication as soon as you recognize symptoms. Quick-relief medicines should only be taken when needed and should not replace long-term medicines.
Having asthma does not mean that you'll have a high-risk pregnancy.
