What are the Causes of Chronic Cough?

Chronic coughing refers to a cough that does not get better or go away. It can be a symptom of many different conditions, some minor and some serious. To determine the causes of chronic cough, it is important to identify additional symptoms or issues that could be contributing factors. Many health experts recommend seeing a doctor if a undiagnosed chronic coughing condition occurs.

One of the major causes of chronic cough is smoking. This habit irritates the throat and lung tissues, leading to a persistent cough in some cases. Coughing due to smoking can be a serious symptom, as it may be a sign of a degenerative lung condition such as emphysema. Smokers who develop a chronic cough should quit without delay and consult a physician to determine if an underlying illness is present.

Infections are common causes of chronic coughs. Bronchitis and pneumonia are common terms for bacterial, fungal, or viral infections that affect the lungs and respiratory system. In these cases, coughing may occur as a way to expel mucous from the lungs and throat. It is not uncommon for coughing to last several weeks after a bout of bronchitis or pneumonia, particularly if the infection is an untreatable viral condition. If other symptoms clear but a cough remains after several weeks, additional tests may be needed.

Asthma is a narrowing of the airways that can be a result of many different environmental factors, including extreme temperatures, strenuous exercise, and allergies. A dry, wheezing chronic cough can occur with asthma, and may be one of the first signs of an asthma attack. Asthma is usually treated with broncodilators, which relax the airways and may help reduce or stop chronic coughing.

Some causes of chronic cough are related to allergies. People may be allergic to pet dander or hair, dust, mold, fungus, or certain chemicals and fragrances. One of the common symptoms of those suffering from mold exposure in a house or workplace is a persistent cough. Allergies can also cause nasal drip, which may irritate the throat and lead to coughing. Doctors can perform allergy tests to determine which substances may be causing the problems, but avoiding exposure can often be difficult.

Since there are so many causes of chronic cough, visiting a doctor may be the best way to determine correct treatment. Most doctors will order a chest X-ray to rule out or examine possible conditions that are causing the cough. While the symptoms of chronic coughing may be treated with cough suppressant medication, the underlying causes of chronic cough may need to be fought with antibiotics, lifestyle changes, or other forms of treatment.
