What Is Asthma?

Asthma is an inflammatory disorder of the airways. It is a disease where the inflammation of the airways causes the restriction of air into and out of the lungs. Asthma is associated with shortness of breath, chest tightness, coughing, and wheezing. Unfortunately there is no cure for asthma, although symptoms sometimes decrease over time.

How Common Is Asthma?

    Studies have shown that 7-10% of children and 3-5% of adults suffer from asthma. Of the population that suffers from asthma, half of them develop the condition before the age of 10. Symptoms, especially in children, can decrease over time.

What Causes Asthma Attacks?

    Asthma can be caused by inhaled allergens. These allergens can be from a number of things-pollens, molds, pet dander, and dust mites.

What Happens When An Asthma Attack Occurs?

The bronchial tree muscles become tight during an asthma attack and the lining of the air passages swells. This swelling of the passages reduces airflow in and out of the lungs, which causes a wheezing sound.

Asthma attacks can happen at any time and can be triggered by a number of things. These attacks can last several minutes to a couple days. As you can imagine, due to the severity of the attack, these attacks can be very dangerous and even deadly.

Asthma Medications

There are many different types of medications out on the market to treat asthma. However, since this article is not meant to diagnose or treat this condition (and since I am not a doctor), I am going to refrain from putting any specific medication names in the article. It is best to talk to your doctor in order to find a medication that suits your needs.

Most initial treatments however, are aimed specifically on avoiding the things that trigger the condition such as pet dander, dust mites, molds, pollens, and smoke. By avoiding these allergens, no medication is needed to treat the condition. If these allergens are unavoidable, that is where medication is needed.

Tips for avoiding asthma attacks due to allergens:

  • Encasing mattresses and pillows in special allergen-impermeable covers
  • Remove carpeting from bedrooms
  • Vacuum the house regularly
  • Lower indoor humidity
  • If allergic to house pets, keep them out of the individuals bedroom
  • Stay clear of smoke, pollution, dusts, and fumes

There are two types of medication that are available for treatment. There are long-term control medications that are used on a regular basis to help prevent attacks from happening. Long-term control medication is not meant to be used during an attack. The second type of medication is quick relief (rescue) medication, which is to be used to relieve symptoms during an actual attack.
