Laizhu Ren said, the typical manifestations of asthma, chest tightness, shortness of breath and wheezing, may be with or without a cough, but clinically there are some special types of atypical symptoms, such as cough variant asthma would only manifested as chronic cough, such as other sports asthma, drug-induced asthma, occupational asthma occurs only wheezing and other asthma symptoms under certain circumstances.
Cough more than eight weeks to check lung function
In fact, a cough is the body's self-protective reaction, when productive cough may promote mucus discharge, non-productive cough is likely to cause allergic airway hyperresponsiveness, in particular to be more vigilant nocturnal cough asthma.
Laizhu Ren said, coughing over 8 weeks can be defined as chronic cough, pulmonary clinic is the more common symptoms. The main reason cough variant asthma, postnasal drip, rhinitis or sinusitis, gastroesophageal reflux cough , where about one-third of adults with chronic cough is caused by a cough variant asthma cough variant asthma is a special type of asthma, cough is the main clinical manifestations, no wheezing, shortness of breath and other symptoms and signs. mainly irritating cough, cough is usually more intense, an important feature for nighttime cough, cold, cold air, dust, fumes, etc. likely to cause or aggravate coughing.
Patients with chronic cough should go to the Department of Respiratory Medicine clinic, doctors generally do chest X-ray, lung function and nitric oxide, etc. Once the diagnosis should be carried out as soon as possible a standard anti-asthma treatment, that inhaled corticosteroids and bronchodilators. Such patients should be allergen testing, we found allergenic future should avoid contact.

Laizhu Ren remind patients, physicians have 'died asthma inner and outer dead ringworm' one said, can not cure asthma, should not rely on the so-called 'cure' misleading. Some unscrupulous traders and arena Youyi doping excess hormone drugs in medicine, Although effective, but side effects great, easy to form refractory asthma.
Experts remind: chronic cough or medication, exercise, and at work often feel shortness of breath, should go to hospital for examination as soon as possible to exclude the diagnosis of asthma and asthma allergens found begin asthma treatment, asthma treatment focuses on norms and adhere to, as long as. according to doctor's instructions correct medication, asthma can be controlled.
