What Is Asthma?

Asthma is a chronic, or long-term, disease that inflames and narrows the airways of your lungs. Asthma causes a variety of symptoms that can worsen at any time, making breathing difficult. Unfortunately, there is no cure for asthma. Even when you are not having symptoms, you may still have inflammation in your lungs. However, by working closely with your healthcare provider to manage your asthma, you may be able to help get your symptoms under control.

A LOOK INSIDE YOUR LUNGS


CAUSES OF ASTHMA

The main components of asthma are airway inflammation and airway constriction. Both components affect the airways of your lungs, making it more difficult for you to breathe. It's important to treat asthma symptoms as soon as you notice them to help prevent them from getting worse or causing a severe asthma attack. That’s why it’s so important to work closely with your healthcare provider in managing your asthma.

AIRWAY INFLAMMATION

When you have asthma, the airways of your lungs can be more sensitive to allergens and to irritants like smoke and dust. This causes the immune system to overreact and produce persistent inflammation in the airways. Inflammation can cause a swelling of the lining of the airways, reducing the amount of air that you take in or breathe out. In some cases, too much thick mucus is produced, which further obstructs the airways.

Your airways may be inflamed even when you aren't having symptoms. When the airways stay inflamed over time, they may become more sensitive to asthma triggers. Then, each time you are exposed to triggers, your inflammation and symptoms may get worse.

AIRWAY CONSTRICTION

Airway constriction, or bronchoconstriction, often accompanies inflammation. You may feel a tightening in your chest as the muscles around your airways constrict, or squeeze together. When this happens to airways already narrowed by inflammation, it may obstruct the airways further and make it even harder for you to breathe.

THE EFFECTS OF ASTHMA

Together, airway constriction and airway inflammation can result in the common asthma symptoms that you may experience from time to time: wheezing, coughing, chest tightness, or shortness of breath.
