What Are the Signs and Symptoms of Asthma?

Common asthma symptoms include:

• Coughing. Coughing from asthma is often worse at night or early in the morning, making it hard to sleep.
• Wheezing. Wheezing is a whistling or squeaky sound that occurs when you breathe.
• Chest tightness. This may feel like something is squeezing or sitting on your chest.
• Shortness of breath. Some people who have asthma say they can't catch their breath or they feel out of breath. You may feel like you can't get air out of your lungs.

Not all people who have asthma have these symptoms. Likewise, having these symptoms doesn't always mean that you have asthma. A lung function test, done along with a medical history (including type and frequency of your symptoms) and physical exam, is the best way to diagnose asthma for certain.

The types of asthma symptoms you have, how often they occur, and how severe they are may vary over time. Sometimes your symptoms may just annoy you. Other times they may be troublesome enough to limit your daily routine.

Severe symptoms can threaten your life. It's vital to treat symptoms when you first notice them so they don't become severe.

With proper treatment, most people who have asthma can expect to have few, if any, symptoms either during the day or at night.

What Causes Asthma Symptoms To Occur?

A number of things can bring about or worsen asthma symptoms. Your doctor will help you find out which things (sometimes called triggers) may cause your asthma to flare up if you come in contact with them. Triggers may include:

• Allergens found in dust, animal fur, cockroaches, mold, and pollens from trees, grasses, and flowers
• Irritants such as cigarette smoke, air pollution, chemicals or dust in the workplace, compounds in home décor products, and sprays (such as hairspray)
• Certain medicines such as aspirin or other nonsteroidal anti-inflammatory drugs and nonselective beta-blockers
• Sulfites in foods and drinks
• Viral upper respiratory infections such as colds
• Exercise (physical activity)

Other health conditions—such as runny nose, sinus infections, reflux disease, psychological stress, and sleep apnea—can make asthma more difficult to manage. These conditions need treatment as part of an overall asthma care plan.

Asthma is different for each person. Some of the factors listed may not affect you. Other factors that do affect you may not be on the list. Talk to your doctor about the things that seem to make your asthma worse.
