Coughing with phlegm, also known as a productive cough, is a common symptom of many respiratory illnesses. While it can be annoying and inconvenient, it is usually not a cause for concern. However, if your cough with phlegm persists for more than three weeks, it is important to see a doctor to rule out any underlying medical conditions.
Causes of Cough with Phlegm for 3 Weeks
There are many possible causes of a cough with phlegm that lasts for three weeks or more. Some of the most common causes include:
- Bronchitis: Bronchitis is an inflammation of the bronchial tubes, which are the large airways that carry air to and from the lungs. Bronchitis can be caused by a virus, bacteria, or other irritants.
- Pneumonia: Pneumonia is an infection of the lungs that can be caused by bacteria, viruses, or fungi. Pneumonia can cause a cough with phlegm, fever, chills, and shortness of breath.
- Tuberculosis (TB): TB is a bacterial infection that can affect the lungs, lymph nodes, and other parts of the body. TB can cause a cough with phlegm, fever, night sweats, and weight loss.
- Chronic obstructive pulmonary disease (COPD): COPD is a group of lung diseases that cause inflammation and narrowing of the airways. COPD can cause a cough with phlegm, shortness of breath, and wheezing.
- Asthma: Asthma is a chronic respiratory disease that causes inflammation and narrowing of the airways. Asthma can cause a cough with phlegm, wheezing, and shortness of breath.
- Heart failure: Heart failure is a condition in which the heart is unable to pump enough blood to meet the body’s needs. Heart failure can cause a cough with phlegm, shortness of breath, and fatigue.
- Cancer: Lung cancer and other types of cancer can cause a cough with phlegm. Other symptoms of cancer may include weight loss, fatigue, and shortness of breath.
