What causes dizziness, chest tightness and shortness of breath? These are the causes

Dizziness, chest tightness and shortness of breath are symptoms of many diseases. If the situation is serious, you need to go for a check-up in time. Common causes include active myocarditis, anemia, hypoglycemia, hypotension and cardiovascular dysfunction. In particular, myocarditis should be treated promptly.

1. Active myocarditis : There may be symptoms such as palpitations, panic, tachycardia, arrhythmia, chest tightness and shortness of breath, which 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 clear cause of the disease. Fasting blood sugar is usually normal. It generally does not cause hypoglycemia when fasting, and the attack time is often 2 to 4 hours after a meal (11 am or 3 pm). The symptoms are mild and rarely cause loss of consciousness. The early symptoms of hypoglycemia are palpitations, fatigue, hunger, hand tremors, cold sweats, pale complexion, cold limbs, or nausea and vomiting; it is mainly caused by excessive excitement of the sympathetic nerves and excessive adrenaline:

Hypoglycemia is episodic, not frequent, and rarely causes 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, but blood pressure of around 60/90 generally does not cause changes in blood supply.

5. Cardiovascular dysfunction :

It is very common in clinical practice. The symptoms are: patients feel chest tightness, shortness of breath, subjective feeling of insufficient air, difficulty breathing, often sighing, feeling comfortable after deep breathing or long exhalation; sometimes accompanied by palpitations, tachycardia, stabbing pain in the precordial area, as well as fatigue, dizziness, confusion, insomnia and other neurological symptoms. Symptoms are often induced or aggravated by mental factors. It may also be accompanied by chronic pharyngitis, such as foreign body sensation in the throat.

Patients often feel that their symptoms are obvious, but no organic lesions are found in electrocardiogram, cardiac B-ultrasound, chest X-ray, etc. The mechanism of this disease is autonomic dysfunction and increased sympathetic nerve tension. Suggestions:

If there is an organic disease, treatment should be targeted at the cause; Treatment of cardiovascular dysfunction:

1. Adjust your mindset, relax your spirit, and eliminate worries. If it is a neurological functional symptom, you don't have to worry too much. After mental conditioning, physical fitness, or necessary rest and drug treatment, it will gradually get better and heal.
