Why do I always feel chest tightness and shortness of breath recently?

I don't know your age and city. If it is because the weather is overheated recently, it is necessary to take part in more sports and practice running, improve heart and lung function and increase vital capacity. But if it weren't for the weather, you'd better go to the hospital for a check-up. Because the appearance of chest tightness may indicate the existence of some organic or functional diseases, it should not be underestimated.

Chest tightness is a subjective feeling, that is, difficulty or insufficient breathing. In severe cases, I feel as if my chest was crushed by a stone, and even I have difficulty breathing. It may be the functional manifestation of body organs, or it may be one of the earliest symptoms of human diseases.

First, functional chest tightness: staying in a poorly ventilated room for a long time, or encountering some unpleasant things, or even quarreling with others, or in a low-pressure climate, often leads to chest tightness and fatigue. After a short rest, open the window for ventilation or breathe fresh air outdoors, relax and adjust your mood, and you will soon return to normal. Chest tightness like this may be functional.

Second, pathological chest tightness: caused by diseases of certain organs in the body, that is, pathological chest tightness. Such as: 1. Respiratory tract obstruction: tracheobronchial tumor, tracheal stenosis, tracheal external pressure (goiter, mediastinal tumor); 2. Lung diseases: emphysema, asthma, atelectasis, pulmonary infarction, pneumothorax; 3. Heart disease: some congenital heart diseases, rheumatic valvular heart disease, coronary heart disease; 4. Diaphragm diseases: diaphragm swelling, diaphragm paralysis; 5. Body fluid metabolism and acid-base imbalance.

Chest tightness in children often suggests congenital heart disease, myocarditis or mediastinal tumor; Chest tightness in young people often suggests spontaneous pneumothorax, mediastinal tumor and rheumatic valvular heart disease. Chest tightness in the elderly often suggests emphysema, coronary heart disease and so on.
