Persistent Cough and Its Ten Potential Medical Causes

A cough is a tricky symptom because a wide range of issues can cause it. If the cough persists for longer than a few days, many people assume that an infection or a more serious condition is responsible. However, even a cough that lasts for weeks can originate from a minor issue. Understanding other symptoms of conditions that cause coughing can help people determine if they require medical attention.

1. Environmental Irritants

Many airborne irritants and pollutants can stimulate a cough, and nearly every breath of air that contains these chemicals or particles will result in this reflex. Persistent coughing at home often stems from dust and mold. Sometimes, air that is too dry or too cold can also irritate the throat and cause a chronic cough.
