Symptoms of wheezing in the elderly may be related to respiratory diseases, heart diseases and pulmonary vascular diseases. 1. Respiratory system diseases: mostly seen in acute exacerbation of chronic bronchitis, or acute exacerbation of chronic obstructive pulmonary disease. Because both diseases are chronic inflammatory diseases of the airways, they can cause restriction of respiratory airflow, and therefore lead to symptoms of shortness of breath during acute exacerbation or acute exacerbation. 2. heart disease: such as acute and chronic cardiac insufficiency, i.e. heart failure. Because cardiac insufficiency causes pulmonary stasis, leading to lung ventilation and air exchange dysfunction, thus causing hypoxia, resulting in asthma symptoms. 3. Pulmonary vascular disease: including pulmonary embolism. The source of thrombus in patients is mostly the veins of lower limbs, especially in cerebrovascular disease, bone fracture, postoperative bed-ridden braking patients, slow blood flow in lower limbs is easy to form thrombus. After the thrombus is dislodged, it can reach the right atrium and right ventricle with the blood circulation, and finally to the pulmonary artery to cause pulmonary embolism, and the patient may have obvious dyspnea, such as the symptom of wheezing. Elderly people may experience wheezing and dyspnea due to physical weakness, cellular aging and chronic diseases, such as type 2 diabetes and hypertension. Elderly people have more diseases, need to go to the hospital in time for consultation, and for the cause of wheezing for symptomatic treatment.
