Also known as: Chronic Cough (>8 weeks)
A chronic cough is defined as a cough lasting more than 8 weeks in adults. It is one of the most common reasons for medical visits and can significantly impact quality of life.
Chronic cough affects approximately 10-20% of adults. The three most common causes — post-nasal drip, asthma, and GERD — account for over 90% of cases in non-smokers with normal chest X-rays.
ACE inhibitor medications (used for blood pressure) cause chronic dry cough in up to 15% of patients and should always be considered.
Less common but important causes include chronic bronchitis, bronchiectasis, and in rare cases, lung cancer. Cough lasting over 8 weeks always warrants medical evaluation.

These blood pressure medications cause dry cough in 5-15% of patients due to bradykinin accumulation.
These approaches may help manage chronic cough at home. Always consult a healthcare provider if symptoms persist or worsen.
