What is the cause of chest tightness and shortness of breath and how is it caused?

People can't live without breathing, and we also have a respiratory system in our bodies. Without its operation, we can't exercise normally! Now, many people will have symptoms of dyspnea. Difficulty in breathing is that our body feels that there is not enough air outside and it is difficult to breathe. Now many people suffering from lung disease will have such symptoms. Some people ask, what is the cause of this phenomenon? The following small series talks about my opinion.

The normal movement of the human body is inseparable from breathing, and dyspnea may also cause serious consequences such as suffocation. Therefore, in normal times, if there are such patients at home, we must pay attention to them. What is the cause of dyspnea? We all know that our bodies breathe through the lungs. When some diseases occur in our lungs, it may become difficult to breathe, and lung cancer patients will have this symptom. Therefore, it is very important to protect the health of the lungs. Smoking is particularly harmful to the lungs. If you want to make your lungs healthier, quit smoking quickly. Like tuberculosis, it can also cause dyspnea, so when the lungs are damaged, the human body will have problems breathing.

Secondly, cardiovascular diseases can also lead to dyspnea. The lungs are used for ventilation. After oxygen enters the blood, it also needs the circulatory system in our body to work. If the heart function is impaired, it will also lead to difficulty breathing. And blood system diseases. After oxygen is inhaled into the lungs, blood needs to be transported and transported. Oxygen binds to hemoglobin. If the blood system in the body is diseased, it will lead to decreased hemoglobin and difficulty breathing. The nervous system in our body can also cause dyspnea. If there is something wrong with the respiratory center, the oxygen intake in the human body will be less, and dyspnea will follow.

The normal movement of the human body can not be separated from breathing, so we must protect our body, and our usual life and eating habits must be good. No smoking, no drinking, more exercise! In particular, priority should be given to exercise, chest expansion and more oxygen inhalation.

The above is Bian Xiao's opinion. Do you think there are other reasons?
