Coughing is one of the most common symptoms of illness, yet it can range from harmless throat irritation to a sign of a more serious health condition. Understanding the different types of cough, their causes, and warning signs can help you manage your health better and know when it’s time to seek medical attention.
In this guide, we’ll break down every major type of cough, what causes them, and when you should be concerned.
