What causes asthma?

Answer 1

Asthma is a chronic respiratory disease, often arising from allergies, that is characterized by sudden recurring attacks of labored breathing, chest constriction, and coughing. Some times it is hereditary also.
In most cases, asthma is caused by inhaling an allergen that sets off the chain of biochemical and tissue changes leading to airway inflammation, bronchoconstriction, and wheezing. Because avoiding (or at least minimizing) exposure is the most effective way of treating asthma, it is vital to identify which allergen or irritant is causing symptoms in a particular patient. Once asthma is present, symptoms can be set off or made worse if the patient also has rhinitis (inflammation of the lining of the nose) or sinusitis. When, for some reason, stomach acid passes back up the esophagus in a reaction called acid reflux, this condition also can make asthma worse. In addition, a viral infection of the respiratory tract can inflame an asthmatic reaction. Aspirin and drugs called beta-blockers, often used to treat high blood pressure, also can worsen the symptoms of asthma. But the most important inhaled allergens giving rise to attacks of asthma are:

-animal dander
-dust mites
-fungi (molds) that grow indoors

The most effective treatment for asthma is identifying triggers, such as pets or aspirin, and limiting or eliminating exposure to them. Desensitization to allergens has been shown to be a treatment option for certain patients.

As is common with respiratory disease, smoking adversely affects asthmatics in several ways, including an increased severity of symptoms, a more rapid decline of lung function, and decreased response to preventive medications. Asthmatics who smoke typically require additional medications to help control their disease. Furthermore, exposure of both nonsmokers and smokers to secondhand smoke is detrimental, resulting in more severe asthma, more emergency room visits, and more asthma-related hospital admissions. Smoking cessation and avoidance of secondhand smoke is strongly encouraged in asthmatics.

The specific medical treatment recommended to patients with asthma depends on the severity of their illness and the frequency of their symptoms. -

Answer 3

Hi,

Asthma is a lung condition that causes wheezing, coughing, and shortness of breath.

The main causes are some allergen, like - cold air, viruses, tobacco smoke, dust, pollen, moulds, and animal dander.

When exposed to irritants or allergens, the airways become more swollen and begin to make excess mucus.

The tiny muscles in the walls of the airways begin to contract.

These reactions decrease the airway openings, making it harder for air to move in and out.

Answer 4

sometimes ur born with it and sometimes u get from smoking long time and that is called reactive air disease not asthma.sometimes its trigged by hayfever and sometimes happens with oders.sometimes its triggered by ppl who do smoke but that is total differnt from astma. most geneal you are born with it.if you do indeed have astma wear something around ur neck or wrist so that if u have attack someone around u can help u and dont forget to take ur inhaler with u just case ya need a puff.my reactive airway disease i need two inhalers but just need one to have on me all times just in case.in sometimes u get asthma if ur not shape just say being over weight.good luck to u and ur asthma

Answer 5

accumulation of inflammatory cells and immune cells in your lungs and airways that are very sensitive to certain stimuli. these are different for people, but include cold air, exercise, pollutants and perfumes. basically the airways constrict after these triggers causing shortness of breath and difficulty breathing.

Answer 6

This chronic respiratory trouble causes, cough, wheezing and respiratory troubles. The airways remain constricted that causes shortness of breath. Any sort of allergens including dust, pollen or smoke can be responsible for the disease. To have a soothing touch try out a cough repellant made using natural remedies. Salveo Life Sciences has come up with a Lobodil suspension that is extremely effective in healing the chronic asthma condition.
