What's up with blood in saliva

Saliva is the liquid secreted by the human mouth. This liquid plays a very important role. It is a substance that protects the oral lining and prevents various diseases caused by dry mouth. It can also play a role in the initial digestion of food. However, saliva can also easily show some abnormal health symptoms. For example, what's the matter with blood in the saliva? Let’s take a look at the explanation below, I hope everyone can understand it.

If the first sputum in the morning contains blood, be careful to distinguish whether it is from the nasal cavity, trachea, or oral cavity. Most of the mucus coming from the nasal cavity is exhaled by sucking it back into the mouth. Those coming from the trachea and bronchi are coughed out. When you wake up in the morning, don't cough or sniff your nose, but spit out some saliva to see if there is any blood? If so, it means the blood comes from the mouth. At this time, you can check whether the teeth and gums are bleeding. If not, it may be coming from the nasal cavity or snow tube. First, you can go to the ENT department to check the nasal cavity and nasopharynx, paying special attention to the nasopharynx, then check the throat to see if there is bleeding, coagulation, or diseases that can cause bleeding, and finally check the lungs, trachea, and bronchi, eliminating the problems step by step.

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 may 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 can be seen in pulmonary edema.

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