What is the reason for chest tightness and shortness of breath in rainy days?

Chest tightness and shortness of breath in rainy days may be caused by myocardial ischemia or bronchial asthma, which can be treated with oral drugs.

1, myocardial ischemia: myocardial ischemia may be caused by insufficient blood supply to the heart, and the clinical manifestations are generally chest tightness, shortness of breath, palpitation and other symptoms. If it rains, the atmospheric pressure is low, leading to chest tightness. Can be treated with isosorbide dinitrate or nitroglycerin under the guidance of a doctor.

2. Bronchial asthma: Bronchial asthma is a chronic airway inflammation, which may be related to genetic factors, or it may be caused by dust mites and pollen factors entering the air. Symptoms such as cough, chest tightness and shortness of breath usually occur. If it is rainy, the bronchus is in a state of continuous spasm, and the oxygen supply to the body tissue is insufficient, which will lead to chest tightness and shortness of breath. Ambroxol hydrochloride tablets or salbutamol can be taken under the guidance of a doctor for treatment.

Pay attention to taking medicine on time and in quantity during the treatment, and never take medicine privately to avoid adverse reactions. Also pay attention to keep warm to avoid getting cold and aggravating the illness, which is not conducive to physical recovery.
