Infomration about Asthma and how it is caused

Asthma is a disease that affects your lungs and breathing. According to the Center for Disease Control, asthma affects over 25 million Americans every day. It is most common among children but adults can have asthma as well. Cases can be mild, that only affects a person one to two times a week, to severe, that affects a person everyday, several times a day. Sometimes asthma can even be life-threatening.

We don't know exactly how a person contracts asthma or how to cure all cases of it but we do know that it can be hereditary. It is important to talk to your doctor if you think you might have asthma, so that they can monitor and help you control your breathing. If you suffer from asthma, it can affect you at any point during the day, typically when something is bothering your lungs like allergies or exercise.

How asthma is caused?

Asthma can occur two ways. The first way is by inflammation of the breathing tubes or bronchi. It is important to know that asthma is present even when the person is not having an attack and breathing normally. The underlying inflammation that can cause swollen airways, drastically reduces the size of the airway, making it hard for air to pass through to breathe. Mucous that is within your body clogs up the airways even more making it even harder to breathe.

The other way that asthma occurs is by bronchoconstriction. The bronchi are the tree-root-looking tubes that help deliver air to the lungs. These tubes have a layer of smooth muscle in them. A person with asthma has thicker muscles than the average person. When an asthma attack is triggered (usually due to breathing in something irritating like smoke, air pollution, mold, pet dander), the muscles in the bronchi squeeze together, causing the air passageways to narrow, making it difficult to breathe.

What are some common symptoms of asthma?

Some common asthma symptoms include but are not limited to:

  • Wheezing
  • Breathlessness or trouble breathing
  • Chest tightness
  • Coughing at night or early in the morning
