Excuse me, how is shortness of breath easy to breathe?

First, common causes such as: 1, active myocarditis: symptoms such as palpitation, palpitation, tachycardia, arrhythmia, chest tightness and shortness of breath should be checked and ruled out. 2. Hypoglycemia: The most common is idiopathic functional hypoglycemia, which is more common in middle-aged women. It is characterized by no definite cause. Blood sugar is normal on an empty stomach. Generally, it does not cause hypoglycemia attack, but the attack time is usually 2~ 4 hours after meals (1 1 p.m. or 3: 00 p.m.), and the attack symptoms are mild and the loss of consciousness is less. The early symptoms of hypoglycemia are palpitation, fatigue, hunger, shaking hands, cold sweat, pale face, cold limbs or nausea and vomiting. It is mainly caused by excessive excitement of sympathetic nerve and adrenaline. Hypoglycemia is paroxysmal, not recurrent, and there are fewer symptoms of chest tightness and shortness of breath. 3, anemia: anemia can cause dizziness, palpitations, tachycardia and other symptoms, but generally does not cause chest tightness. 4, low blood pressure: It also mainly causes dizziness symptoms, but the blood pressure is around 60/90, which generally does not cause changes in blood supply. 5. Cardiovascular dysfunction: very common in clinic. The symptoms are as follows: patients feel chest tightness and shortness of breath, subjective feeling of lack of breath, poor breathing, frequent sighing and breathing, deep breathing or feeling comfortable after breathing; It is often accompanied by palpitation, tachycardia, tingling in precordial area, and nervous system symptoms such as fatigue, dizziness, confusion and insomnia. Symptoms are often induced or aggravated by mental factors. It may also be accompanied by chronic pharyngitis, such as foreign body sensation in the pharynx. Examination: ECG, B-ultrasound, myocardial enzyme, chest X-ray, blood routine and blood sugar are recommended; If there is fasting hypoglycemia, further examination such as pancreatic B-ultrasound or CT should be done to rule out hypoglycemia caused by pathological reasons. If heart and lung diseases, hypoglycemia and other diseases can be ruled out after examination, cardiovascular dysfunction can be considered. Second, about the treatment: 1, adjust the mentality, relax the spirit, and eliminate concerns. If it is a symptom of nervous system, don't worry too much. After mental conditioning, physical exercise, or necessary rest and medication, it will gradually improve and be cured. 2. After excluding pathological or organic pathological changes, physical exercise can be carried out appropriately: strengthening physical fitness, improving cardiovascular function and enhancing the regulating function of autonomic nerve are conducive to the recovery of autonomic nerve function. 3.
