Difficulty in expiration and shortness of breath are likely to be caused by mental stimulation, chronic obstructive pulmonary disease and coronary heart disease.
1. Mental stimulation: If you are suddenly overly frightened, have nightmares at night or are overly nervous, which increases sympathetic excitability, you may experience abnormal manifestations such as difficulty in breathing out and shortness of breath.
2. Chronic Obstructive Pulmonary Disease (COPD): COPD affects the normal physiological function of the lungs, and when subjected to external stimuli, such as excessive cold, mental stimulation and physical labor, the symptoms of dyspnea and shortness of breath will occur.
3. Coronary heart disease: coronary arteries are blood vessels that supply blood and oxygen to the heart muscle cells, if the coronary arteries do not receive sufficient blood and oxygen supply due to lesions, dyspnea and breathlessness can occur.
4. Difficulty in breathing and shortness of breath may have other causes.
It is recommended that patients with dyspnea and shortness of breath go to a regular hospital to find out the cause of the disease and follow the advice of a professional doctor to choose a treatment that suits them.
