What causes difficulty breathing during exercise

Many people like to exercise, not only because it can strengthen the body and lose weight, but also because many people like the feeling of sweating profusely after exercise. Exercise gives people a pleasant feeling, but for some people, exercise is very painful, because some people always feel difficulty breathing during exercise. So what causes difficulty breathing during exercise? Now let me tell you.

Toxic breathing difficulties. Acidosis caused by various reasons can increase carbon dioxide in the blood and decrease pH, stimulate peripheral chemoreceptors or directly excite the respiratory center, increase respiratory ventilation, and manifest as deep and severe dyspnea. Poisoning with respiratory depressants such as morphine and barbiturates can also inhibit the respiratory center, causing shallow and slow breathing.

Hematogenous dyspnea. Severe anemia can cause shortness of breath due to a decrease in red blood cells and lack of blood oxygen, especially after activity. In case of massive hemorrhage or shock, ischemia and a drop in blood pressure stimulate the respiratory center and cause breathing difficulties.

Neuropsychiatric and myopathic dyspnea. Severe brain diseases such as encephalitis, cerebrovascular accident, brain tumors, etc. directly affect the respiratory center, resulting in abnormal respiratory rhythm and leading to dyspnea; myasthenia gravis crisis causes paralysis of the respiratory muscles, leading to severe dyspnea; in addition, hysteria can also cause dyspnea attacks, characterized by significantly rapid and shallow breathing, because respiratory alkali poisoning is often accompanied by tetany.

Bloating due to an enlarged stomach. Pressing the diaphragm makes the chest cavity smaller and makes breathing difficult. Chest tightness is a subjective feeling, that is, breathing is difficult or there is not enough air. Those with mild symptoms will feel nothing serious, but those with severe symptoms will feel uncomfortable, as if a stone is pressing on their chest, and even have difficulty breathing. It may be a functional manifestation of the body's organs, or it may be one of the earliest symptoms of disease in the human body. The causes of chest tightness in people of different ages are different, the treatments are different, and the consequences are also different.

It is normal to feel shortness of breath after strenuous exercise, but shortness of breath during ordinary exercise means that there is a problem with body function, which may be due to the above reasons. Therefore, everyone must not take it lightly. If you feel difficulty breathing, you should go to the hospital for further examination in time to restore your body to health as soon as possible.
