Content Inside:
Asthma is a condition that makes breathing difficult. This causes a feeling of tightness in the chest.

Patients with asthma are sensitive to certain materials that cause an inflammation or swelling of the inner lining of the lungs. This swelling can cause narrowing of the air passages.

The swelling and inflammation of the inner lining of the lungs can lead to symptoms such as difficulty breathing and tightness in the chest.

The muscles around the bronchial tubes could also tighten abnormally resulting in further narrowing of the air passages.

When an asthma attack occurs, the lining of the lungs quickly becomes swollen. The air passages fill up with thick mucus and the muscles around the bronchial tubes tighten.

This greatly decreases the airflow in the lungs: this could potentially be life threatening.
