However, a chronic cough indicates that the lungs are not functioning properly. In fact, one of the first signs of lung disease is often a cough that doesn’t improve even after taking medication. Coughing is very common and can indicate the onset of a cold, but it can also be a symptom of chronic illnesses. Therefore, it’s important to distinguish between the different types of cough.
Acute and subacute coughs can be a sign of lung cancer, especially when accompanied by other symptoms such as coughing up blood. Therefore, if you develop a sudden cough without any apparent reason, you should see a doctor. If you have increased mucus production , it’s important to drink plenty of fluids to help loosen it.
Increased mucus and sputum
Coughing is usually accompanied by the production of mucus.
Mucus prevents germs, dirt, pollen, and bacteria from entering the lungs. However, increased mucus production, such as during a cold, is not a good sign. Changes in color , smell , or consistency can also occur.
If the mucus turns yellow or green, or contains blood, this is a clear indication that something is wrong with the lungs. Blood in the mucus can point to pulmonary emphysema, chronic bronchitis, or lung cancer.
