Asthma is a chronic inflammatory disease of airways of the lungs. Asthma is often linked to heredity and environment.

Asthma is considered as a major public health problem in many countries. Asthma is one of the most common chronic disease affecting both adults and children.

According to World Health Organization an estimated 300 million people worldwide suffer from asthma, with 250,000 annual deaths attributed to the disease.

Asthma attack is characterized by sudden attacks of labored breathing, chest constriction and coughing.

Traditionally, asthma is considered to be a condition characterized by narrowing of airways where in the patients would gasp for breath.

Despite the availability increasing treatment, asthma-related morbidity and mortality continues to rise.

The prevalence of asthma is increasing in developed as well developing countries through the world. The current prevalence is estimated to be 5 to more than 10%.

In a normal individual, various airborne allergens (triggers) stimulate the production of antibodies and other chemicals in controlled quantity, which destroy the allergen but donít harm the body.

But in allergic individual who have asthma there is over production of antibodies and other chemicals which cause inflammation of the airways, which is hallmark of asthma attack.

1. Wheezing

Things which every body must know about asthma:

Asthma affects millions of people worldwide. It is one of the disease where the incidence of disease is increasing year by year. It is also the most common chronic disease affecting children.

Here are some important facts about asthma that everybody must know:

1. Asthma is not a communicable disease. You cannot get infected and get asthma by any asthma patient. Asthma is disease where genetic and environmental factors play role.

2. Asthma is caused by the chronic inflammation (swelling) of airways of lungs.

3. Airway inflammation contributes to airway hyper responsiveness, airflow limitation (obstruction), epithelial; damage and long term structural remodeling of the airways causing respiratory symptoms.

4. Atopy, the genetic predisposition for the development of an IgE-mediated response to common aeroallergens, is the strongest identifiable predisposing factor for developing asthma.

5. Viral respiratory infections are one of the most important causes of asthma exacerbation and may also contribute to the development of asthma.

6. The main symptoms of asthma are wheezing, coughing, recurrent breathlessness or shortness of breath, tightness of the chest, and pain or pressure on the chest.

7. Diagnosis of asthma is made by detailed medical history, physical examination focusing on the upper respiratory tract, chest and a test called spirometry.

8. Asthma is not a contraindication for doing exercise. Many great athletes suffer from asthma. Read Exercise Induced Asthma to know more.

9. Two main categories of asthma medication are relievers (used to treat symptoms and exacerbations or acute attacks) and preventer (agents for long-term control, used to achieve and maintain control of persistent asthma) medication.

10. Inhaled route is the most preferred way to deliver asthma medication as it delivers drugs directly to lung airways. This makes the action of the drug faster with lower or negligible side effects.

11. Asthma is one of the most common potentially life-threatening condition complicating pregnancy. Read pregnancy and asthma.

12. Asthma causes lots of financial burden to the society. This is principally related to the drug therapy, medical cost of hospitalization and emergency care. loss of work days and school also contributes indirectly to this. According to Weiss and Sullivan,2 in 1998, asthma resulted in more than $5.3 billion in indirect costs: $1.2 billion for lost school days, $1.5 billion in lost workdays, $840 million in caregiver/housekeeping costs, and $1.8 billion in mortality costs. The financial cost of asthma to the UK is over £2.3 billion per year.

13. Remember that asthma is a treatable disease and you can live a healthy and productive life like any body else with proper treatment. Any query go to asthma FAQs.
