If you've been coughing for more than a month, it's natural to feel concerned. A persistent cough can be a sign of various underlying medical conditions, ranging from minor irritations to more serious illnesses. This informative article aims to help you understand the common causes of a prolonged cough and when it's appropriate to seek professional advice.
Coughing is a natural reflex that helps protect your airways from foreign particles and irritants. However, a cough that lasts for more than four weeks is considered chronic and requires further investigation. Chronic coughs can be categorized as either productive or non-productive, depending on whether they produce sputum (mucus and cells from the lungs).
While a persistent cough can be a symptom of a medical condition, it's important to remember that not all coughs warrant immediate medical attention. In the next sections, we will delve into the common causes of a cough lasting over a month and provide guidance on when it's essential to seek professional help.
Cough for over a Month
A persistent cough lasting more than four weeks requires attention and may indicate an underlying medical condition.
