Chronic coughing can be due to numerous health-related complications. Here are some common reasons why your cough lingers for weeks.

Respiratory infection: Inflammation of the air passage or irritation in the air passage due to some allergens may be a reason for your cough.

Hyperactive gag reflex and acid reflux: Both these conditions may cause prolonged irritation in your throat and make your condition worse from time to time.

Medications: Be careful about the drugs you are taking on a day to day basis. Blood pressure drugs are one of the common drugs that leads to coughing.

Smoking: Avid smokers generally complain about coughing. This is actually a way through which our body removes chemicals that enter the airways and lungs through nicotine use.
