Doctors called a prolonged cough without visible irritants a very dangerous sign. It can indicate the development of serious diseases, up to tuberculosis and lung cancer.

The cause of a cough is often external irritants that affect the respiratory tract. This can be either a common allergy or a protective reaction, or a reason to see a doctor. Doctors explained that if even a small amount of blood is coughed up, you should consult a specialist as soon as possible. Such a symptom indicates not only a clear violation of the body's functioning, but in some cases is a symptom of the development of cancer or tuberculosis. The latter is characterized by rapid weight loss and increased sweating at night.

You should not postpone a trip to the doctor if phlegm or mucus is released during coughing. Depending on its color, you can determine the presence of diseases in the body. Very thick secretions indicate bronchitis, green or yellow mucus is a clear sign of a virus in the body (sinusitis or pneumonia). In the case of pink foamy fluid when coughing, a trip to the doctor should be a priority, as this phenomenon indicates the accumulation of fluid in the lungs and can cause edema.
