What disease can cause chronic cough

Coughing is a common occurrence and can be caused by many situations, such as choking on water, sore throat caused by a cold, coughing up phlegm caused by getting angry, etc. Many people usually endure a cough for a few days, or take some medicine to relieve the symptoms, but some people cough all year round and no medicine works. Many people want to know what disease is caused by long-term cough. Let’s learn about it together~

What causes a long-term cough? In general, mild and infrequent coughs can be relieved naturally by expelling phlegm or foreign objects. However, long-term severe dry coughs without phlegm, or frequent severe coughs with phlegm, will not only increase the patient's pain, affect rest and sleep, increase physical exertion, but may even cause other complications.

Experts suggest that there is a type of cough that is difficult to detect and is the most likely to occur, which is cough variant asthma. Cough asthma, also known as cough variant asthma, refers to a special type of asthma with chronic cough as the main or only clinical manifestation. Cough is the main clinical symptom of cough variant asthma. Clinically, many patients often think that cough after a cold is "tracheitis" or "bronchitis" and take antibiotics and expectorant cough suppressants on their own.

However, many citizens still cannot relieve their coughs even though they have taken a lot of medicine. Therefore, don’t think that coughing is a minor thing like the “aftermath” of a cold. Taking some expectorant and cough suppressant medicines will slowly get better. Once the cough after a cold does not heal for a long time or a long-term chronic cough occurs, you should go to the hospital in time to find out the cause as soon as possible. Cough variant asthma is also known as allergic cough, latent asthma, and cough asthma. The pathogenesis of this disease is similar to that of typical asthma. The main manifestation is chronic cough, which is mainly irritating dry cough with little sputum, often persisting and recurring at night or early morning, and worsening after exercise; colds, cold air, dust, fumes, etc. can easily induce or aggravate coughs. Most patients with cough variant asthma do not have obvious asthma symptoms, no wheezing can be heard on auscultation, and chest X-rays show normal or increased lung texture, but no other organic changes. This type of patients often have concurrent allergies such as allergic rhinitis, allergic dermatitis, and a family history of asthma.
