Asthma Causes, Symptoms, Treatment & Remedies

A common disorder in which chronic inflammation of the bronchial tubes (bronchi) makes them swell, narrowing the airways. Asthma involves only the bronchial tubes and does not affect the air sacs (alveoli) or the lung tissue (the parenchyma of the lung) itself.

Asthma attacks all age groups but often starts in childhood. It is a disease characterized by recurrent attacks of breathlessness and wheezing, which vary in severity and frequency from person to person. In an individual, they may occur from hour to hour and day to day.

This condition is due to inflammation of the air passages in the lungs and affects the sensitivity of the nerve endings in the airways so they become easily irritated. In an attack, the lining of the passages swell causing the airways to narrow and reducing the flow of air in and out of the lungs.

Asthma Causes :The cause of asthma is not known, but there is evidence that many factors play a part.

Genetic factors: asthma tends to run in families, and many people with asthma also have other allergic conditions such as rhinitis (inflammation of the nose lining). "Allergy" is a hypersensitivity to some proteins foreign to the body; a small dose of the "allergen" will produce a violent reaction in the person concerned.

Environmental factors: in wealthy, hygienic Western countries, most babies are not exposed to bacterial infections that "kick start" the immune system in early life and may be important in directing the immune system away from allergic responses. They also grow up in warm, well-furnished, carpeted homes that don't allow much airflow. This encourages the rapid breeding of large numbers of house dust mites in bedding, carpets and furnishings.

Dietary changes: changes in diet in Western countries, such as a high proportion of processed foods, a higher salt intake, a lower antioxidant intake and a lack of fresh oily fish (lower intake of omega-3 fatty acids) may contribute to the development of asthma.

Asthma treatment : Your doctor can work with you to decide about your treatment goals and what you need to do to control your asthma to achieve these goals. Asthma treatment includes:

Working closely with your doctor to decide what your treatment goals are and learning how to meet those goals.

Avoiding things that bring on your asthma symptoms or make your symptoms worse. Doing so can reduce the amount of medicine you need to control your asthma.

Using asthma medicines. Allergy medicine and shots may also help control asthma in some people.

Monitoring your asthma so that you can recognize when your symptoms are getting worse and respond quickly to prevent or stop an asthma attack.
With proper treatment, you should ideally have these results:

o Your asthma should be controlled.
o You should be free of asthma symptoms.
o You should have fewer attacks.
o You should need to use quick-relief medicines less often.
o You should be able to do normal activities without having symptoms.
