I have a little cough but I bleed when I eat. What's the reason?

Coughing is a very common phenomenon in life. Some people will cough up phlegm when they cough, and even some serious patients will cough up phlegm with blood. When there is blood in the phlegm, everyone will be scared, fearing that they have tuberculosis. In fact, it may also be caused by coughing too hard, resulting in tracheal rupture. So what is the reason for coughing up blood?

For young people, blood in sputum may be caused by lung diseases such as bronchitis, pneumonia, bronchiectasis, and tuberculosis. But if a person over 40 years old has blood in his sputum, he should be alert to the occurrence of lung cancer. You should go to the hospital in time for an X-ray chest examination and sputum exfoliative cytology examination. These two methods are simple, economical, less painful, and have a higher positive rate.

Bloody sputum (sputum with blood streaks or blood clots) may have the following conditions:

First, the presence of bright red blood in the sputum is often seen in tuberculosis or bronchiectasis, and sometimes this phenomenon can also occur when there is inflammation in the pharynx.

Second, black bloody sputum is often seen in pulmonary infarction.

Third, coughing up bloody foamy sputum may be seen in pulmonary edema.

Fourth, if there is blood in sputum for a long time or it is accompanied by chest pain, fatigue, and weight loss, you should be alert to bronchial lung cancer.

Generally, lung X-rays can provide a preliminary diagnosis or exclude a diagnosis.

Chronic pharyngitis is a common disease, which is a diffuse pharyngeal lesion caused by chronic infection, mainly inflammation of the pharyngeal mucosa. It is more common in adults, and its main causes include recurrent acute pharyngitis, long-term irritation from dust or harmful gases, excessive smoking and drinking or other bad living habits, irritation from sinusitis secretions, allergic constitution or reduced body resistance, etc. Chronic pharyngitis can also be a local manifestation of certain systemic diseases, such as anemia, diabetes, cirrhosis and chronic nephritis.
