What It Is

A chronic cough is a cough that lasts longer than eight weeks in adults or four weeks in children. It is often a sign of an underlying condition such as asthma, allergies, post-nasal drip, or acid reflux. Chronic cough can interrupt daily life, disrupt sleep, cause throat irritation, and even lead to headaches or chest soreness. Many people try over-the-counter cough medicines without relief because these do not address the root cause. Identifying why the cough is happening is the most important step toward long-term improvement.

When to See a Specialist

You should seek evaluation if your cough lasts longer than a few weeks, disrupts sleep, or causes difficulty breathing. If coughing is accompanied by wheezing, chest tightness, or recurring infections, professional care is essential. A specialist can help pinpoint whether allergies, asthma, or other respiratory conditions are contributing to your symptoms.
