Asthma Symptoms, Diagnosis, and Treatment
What is Asthma?
Asthma is a condition in which your airways narrow and swell and may produce extra mucus. This can make breathing difficult and trigger coughing, a whistling sound (wheezing) when you breathe out, 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.
Mild Intermittent Asthma
- Symptoms occur less than twice a week, and nighttime symptoms occur less than two times per month.
- Lung function tests are 80% or more above predicted values. Predictions are often made on the basis of age, sex, and height.
- No medications are needed for long-term control.
Mild Persistent Asthma
- Symptoms occur three to six times per week.
- Lung function tests are 80% or more above predicted values.
- Nighttime symptoms occur three to four times a month.
Moderate Persistent Asthma
- Symptoms occur daily.
- Nocturnal symptoms occur 5 or more times per month.
- Asthma symptoms affect activity, occur more than two times per week, and may last for days.
- There is a reduction in lung function, with a lung function test range above 60% but below 80% of normal values.
Severe Persistent Asthma
- Symptoms occur continuously, with frequent nighttime asthma.
- Activities are limited.
- Lung function is decreased to less than 60% of predicted values.
Asthma symptoms vary from person to person. You may have infrequent asthma attacks, have symptoms only at certain times — such as when exercising — or have symptoms all the time. Asthma signs and symptoms include:
- Shortness of breath
- Chest tightness or pain
- Wheezing when exhaling, which is a common sign of asthma in children
- Trouble sleeping caused by shortness of breath, coughing or wheezing
- Coughing or wheezing attacks that are worsened by a respiratory virus, such as a cold or the flu
How is Asthma Diagnosed?
- Taking a medical history, asking about symptoms, and listening to you breathe
- Performing a lung function test, using a device called a spirometer, to measure how much air you can exhale after first taking a deep breath and how fast you can empty your lungs. You may be asked before or after the test to inhale a short-acting bronchodilator (medicine that opens the airways by relaxing tight muscles and also helps clear mucus from the lungs).
- Performing a methacholine challenge test; this asthma test may be performed if your symptoms and spirometry test do not clearly show asthma. When inhaled, methacholine causes the airways to spasm and narrow if asthma is present. During this test, you inhale increasing amounts of methacholine aerosol mist before and after spirometry. The methacholine test is considered positive, meaning asthma is present, if the lung function drops by at least 20%. A bronchodilator is always given at the end of the test to reverse the effects of the methacholine.
Properly using asthma medication, as prescribed by your doctor, is the basis of good asthma control, in addition to avoiding triggers and monitoring daily asthma symptoms. There are two main types of asthma medications:
- Anti-inflammatories: This is the most important type of medication for most people with asthma. Anti-inflammatory medications, such as inhaled steroids, reduce swelling and mucus production in the airways. As a result, airways are less sensitive and less likely to react to triggers. These medications need to be taken daily and may need to be taken for several weeks before they begin to control asthma. Anti-inflammatories lead to a reduction in symptoms, better airflow, less sensitive airways, less airway damage, and fewer asthma episodes. If taken every day, they are helpful in controlling or preventing asthma flares. Oral steroids are taken for acute flares and help increase the efficacy of other medications and help reduce inflammation.
- Bronchodilators: These medications relax the muscle bands that tighten around the airways. This action rapidly opens the airways, letting more air in and out of the lungs and improving breathing. As the airways open, the mucus moves more freely and can be coughed out more easily. Both short-acting and long-acting beta-agonists can be used for the prevention of symptoms of exercise-induced asthma. An anticholinergic which is available for individuals ages 6 and older, is another long-term maintenance medication for treating asthma.
