Some of the most common causes of chronic coughs include sinus complications, tobacco use, hay fever, infections, medications, asthma and acid reflux. A chronic cough is one that lasts more than 8 weeks in adults and 4 weeks in children, according to Mayo Clinic. Dry coughs do not produce any mucus but irritate the lungs and throat.
Cigarette smoking is the most common cause of chronic coughs, notes MedicineNet. The chemical components of cigarettes have a negative effect on the lungs, which is why smokers are at a high risk of the condition.
Asthma is a condition that affects the airways, which is why it ultimately leads to chronic coughing. The condition may be made worse due to cold weather, perfumes, smoke and pollen.
Infections brought by fungi, bacteria or viruses may also end up causing chronic coughs. Some examples of infections that may lead to this condition include pneumonia and bronchitis.
Some medications such as angiotensin converting inhibitors used to treat blood pressure may end up causing chronic coughs in certain individuals. Talking to a doctor to find alternatives can be a good way to resolve this issue.
To properly diagnose a dry cough, doctors may carry out a number of tests, including X-rays, scope tests, lung function tests, lab tests and computerized tomography tests. Treatment of a dry cough generally depends on its cause. Cough lozenges, inhaling steam, drinking a lot of water and over-the-counter medicines are among the most common treatment options, according to MedicineNet.
