Bronchial asthma (or asthma) is a lung disease. Your airways get narrow and swollen and are blocked by excess mucus. Medications can treat these symptoms. Asthma, also called bronchial asthma, is a disease that affects your lungs. It’s a chronic (ongoing) condition, meaning it doesn’t go away and needs ongoing medical management

Causes asthma:

Researchers don’t know why some people have asthma while others don’t. But certain factors present a higher risk: 

Allergies:

Having allergies can raise your risk of developing asthma. 

Environmental factors: People can develop asthma after exposure to things that irritate the airways. These substances include allergens, toxins, fumes and second- or third-hand smoke. These can be especially harmful to infants and young children whose immune systems haven’t finished developing. 

Genetics: If your family has a history of asthma or allergic diseases, you have a higher risk of developing the disease.

Respiratory infections: Certain respiratory infections, such as respiratory syncytial virus (RSV), can damage young children’s developing lungs.

Signs and symptoms of asthma:

People with asthma usually have obvious symptoms. These signs and symptoms resemble many respiratory infections: Chest tightness, pain or pressure.

Coughing (especially at night).

Shortness of breath.

Wheezing.
