Asthma – To Know All About This Disease - By: Robiin hood

You all must have heard of Asthma and Asthmatic Attack. Asthma is a type of allergic disease . Asthma is a predisposition to chronic inflammation of the lungs in which the airways (bronchi) are reversibly narrowed. It is not usually considered as a part of chronic obstructive pulmonary disease as this term refers specifically to combinations of bronchiectasis, chronic bronchitis, and emphysema.

Asthma affects 7% of the population of the United States, 6.5% of British people and a total of 300 million worldwide. During asthma attacks (exacerbations of asthma), the smooth muscle cells in the bronchi constrict, the airways become inflamed and swollen, and breathing becomes difficult. This is often referred to as a tight chest and is a sign to immediately take medication.

Asthma is often inherited. If your family does not have a history of this disease, you are fortunate to have a lesser chance of being affected by asthma. But if any one of your parents deals with asthma, you are likely to acquire this disorder from your parents. In fact, there is a 30% probability that you could inherit this disease from your parents. Common symptom of asthma in a steady-state include: nighttime coughing, shortness of breath with exertion but no dyspnea at rest, a chronic 'throat-clearing' type cough, and complaints of a tight feeling in the chest. Severity often correlates to an increase in symptoms. Symptoms can worsen gradually and rather insidiously, up to the point of an acute exacerbation of asthma.

Asthma is caused by environmental and genetic factors. Some environmental and genetic factors have been confirmed by further research, while others have not been. Underlying both environmental and genetic factors is the role of the upper airway in recognizing the perceived dangers and protecting the more vulnerable lungs by shutting down the airway.

The most effective treatment for asthma is identifying triggers, such as pets or aspirin, and limiting or eliminating exposure to them. If trigger avoidance is insufficient, medical treatment is available. Desensitization has been suggested as a possible cure. Additionally, some trial subjects were able to remove their symptoms by retraining their breathing habits with the Buteyko method. Other forms of treatment include relief medication, prevention medication, long-acting β2-agonists, and emergency treatment.
