What is Asthma

Asthma is a condition that affects the Respiratory System. People who have asthma sometimes have trouble breathing. When people who have asthma have this trouble breathing, we call it an asthma attack. Lots of people have asthma attacks. When most of us breathe, the muscles that are wrapped around the air tubes (airways) are very loose and relaxed, and the lining inside the airways is very thin. This lets the airways open up very wide so that it is easy to get air in and out of the small air sacs that make up your lungs. During an asthma attack, the muscles around the airways tighten, or "spasm" (like when you make a fist) and the lining inside the airways swell or thicken, and get clogged with lots of thick mucous. This makes the airways much thinner than usual so it is harder to move air in and out of the air sacs. This makes it hard to breathe!

Can Asthma Be Treated?

Unfortunately, Asthma has no known cure, but the good news is that it's controllable. There are many different medicines that doctors may use to help people with asthma. Some medicines are swallowed (pills or liquids), some medicines are inhaled (breathed in through your mouth or nose), and some medicines are injected (given as a shot in one of your muscles or veins).

Medicines can work in different ways to help people who have asthma. Here are a few examples:

Doctors usually prescribe bronchodilators first, as bronchodilators are usually inhaled using a metered dosed inhaler. Inhaled medicines are used first because they start working very fast (usually in less than five minutes!) and they don't have too many side effects. This is because inhaled medicines go right into the lungs and not into other parts of the body.

Examples of bronchodilators are:

 

Anti-inflammatory medicines reduce the swelling inside airways and decrease the amount of mucus in the lungs.



While there are many different types of anti-inflammatory medicines, the ones that are used most often in people with asthma are corticosteroids (steroids).

Some common corticosteroids are:
