Breathlessness refers to difficulty in breathing and may be caused by heart disease, lung disease, and obstruction or narrowing of the airways.
1. Heart disease: When suffering from congenital heart disease, cardiomyopathy, coronary heart disease and other diseases, the symptoms of dyspnea may occur, accompanied by shortness of breath, palpitations and other symptoms.
2. Lung diseases: Lung diseases such as asthma, chronic obstructive pulmonary disease (COPD), emphysema, etc. may cause dyspnea.
3. Obstruction or narrowing of the airway: When the airway is obstructed by foreign bodies, goiter, or phlegm is thick and sticky, the airway may be obstructed or narrowed, and dyspnea may occur.
There may be other reasons for dyspnea, so it is recommended to go to a regular hospital in time.
