Coughs can last anywhere from a few days to several weeks, depending on the underlying cause. Common Causes of Coughing
Coughing is a normal reflex that helps clear the throat and airways of irritants, mucus, and foreign particles. It can be caused by a variety of conditions, including:
Upper Respiratory Infections: Viruses, like the common cold, are the most common cause of coughing. A cough caused by a cold usually lasts 10-14 days.
Allergies: Allergens such as pet dander, dust mites, and pollen can trigger a cough. This type of cough may last as long as the person is exposed to the allergen.
Asthma: Asthma is a chronic condition characterized by inflammation and narrowing of the airways. People with asthma may have a persistent cough, especially at night or when exercising.
Gastroesophageal Reflux Disease (GERD): GERD is a condition in which stomach acid flows back up into the esophagus, causing heartburn and a cough. This type of cough can last for weeks or months.
When to See a Doctor
In most cases, a cough will resolve on its own with time. However, if a cough has lasted more than three weeks, it may be a sign of a more serious condition. It is important to seek medical attention if you have any of the following symptoms:
- Severe chest pain
- Wheezing or difficulty breathing
- Coughing up thick, bloody, or brown mucus
- Fever
- Weight loss
- Extreme fatigue
A doctor can help determine the cause of your cough and recommend the best treatment.
