Coughing is a normal body reaction. It is caused by a number of things such as colds or allergies. Short term coughs are normal. However prolonged coughs can signal something serious that needs a doctor's attention. According to Dr. Kelen Aspen from Health Hub a number of factors can lead to prolonged coughs.
Smoking has been cited as a major reason behind prolonged coughs. Chemical infection is the major cause. However, the chemicals that enhance the simple smoker's cough can lead to far more serious conditions, such as bronchitis, emphysema, pneumonia, and lung cancer.
Another major cause is asthma. For one to apprehend asthma, he or she has to recognize a little about what occurs when you breathe. Normally, with every breath you take, air goes through your nose and down into your throat, subsequently making it to your lungs. There are lots of small air passages in your lungs that help deliver oxygen from the air into your bloodstream. Asthma signs and symptoms happen when the lining of these air passages swell and the muscle groups around them tighten. Mucus then fills the airways, further reducing the quantity of air that can pass through. These prerequisites then convey on allergies “attack,” the coughing and tightness in your chest that is traditional of asthma. Among the many various kinds of asthma, cough-variant allergies don’t have basic bronchial asthma signs of wheezing and shortness of breath. This kind of bronchial asthma is characterized through a persistent, dry cough. Cough-variant bronchial asthma can lead to full-blown bronchial asthma flares that encompass the other more common symptoms.The other cause of a persistent cough is bronchitis which is an irritation of the lining of the bronchial tubes. These are the tubes that lift air to and from your lungs. People who have bronchitis regularly have a power cough that brings up thickened, discolored mucus.#hivisasaoriginal
