Asthma is a chronic disease in which the airways that carry air into the lungs become narrow and inflamed.
The narrow and inflamed airways are very sensitive and have a tendency to react with environmental elements known as triggers, like substances that are inhaled.
As the airways react, they swell and contract, even more, producing extra mucus, making air difficult to penetrate the lungs. The muscles around the airways are also stretched, which further limits the flow of air.
Asthma is a disease that affects the airways of the lungs (bronchioles). Asthma is caused by the chronic (persistent, long-term) inflammation of these passages. This makes the airway or respiratory system of the asthmatic person very sensitive to multiple triggers.
When inflammation is “triggered” by a number of external and internal factors, the walls of the channels swell and the openings filled with mucus.
- The muscles of the airways contract and cause further narrowing of the airways.
- This constriction makes it difficult to breathe air from the lungs.
- This resistance to exhalation causes the typical symptoms of an asthma attack.
What are the Asthma Causes?
The exact reason for asthma causes for why people have asthma is not fully understood. Family history and the environment seem to be important for most, but not all.
Insensitive people who inhale substances that trigger allergies (called allergens or triggers) may begin to experience the symptoms of asthma. Triggers are animal hair, mites, cockroach allergens, mold or pollen.
Respiratory tract infections, cold air, stress, physical exertion, tobacco smoke,¬ food sulfites and other air pollutants can also trigger asthma symptoms.
What are the Symptoms of Asthma?
Asthma symptoms may vary from person to person. A person may have infrequent asthma attacks, symptoms only at certain times like when exercising or have symptoms all the time.
Following are some symptoms of asthma including;
- Chest tightness or pain.
- Shortness of breath.
- Trouble sleeping that causes shortness of breath, wheezing, or coughing.
- A whistling or wheezing sound when exhaling (wheezing is a common sign of asthma in children)
Signs that asthma is probably worsening include:
- Increasing difficulty in breathing.
- The need to use a quick-relief inhaler more often.
How are the Asthma Treatments?
Asthma treatment is aimed at controlling airway inflammation and avoiding known triggers for allergies, such as animal dander and pollen.
The main goals are to restore normal breathing, prevent asthma attacks and restore daily activities.
Daily treatment of asthma helps prevent symptoms, and asthma inhalers are the preferred method because the drug can be delivered directly into the lungs at smaller doses and with fewer side effects.
Some asthma medications are also given as a pill or injection.
As we all know that asthma¬ is common nowadays but with little care, we can actually prevent yourselves¬ from this disease. Always make sure that you should take care of¬ yourselves and your loved ones before its too late.
