Shortness of breath after walking up stairs is usually related to cardiopulmonary function, especially in elderly people who experience shortness of breath after walking, which is likely to be caused by chronic lung disease or heart disease. Before treatment, the cause needs to be clarified, and pulmonary function, chest X-ray, and cardiac ultrasound should be done to clarify whether the elderly is caused by heart disease or lung disease. If it is caused by heart disease, cardiac diuretics may be applied for treatment. If it is caused by asthma or chronic obstructive pulmonary disease, inhalation medication, such as bronchodilators like Bifondup, is needed to relieve the symptoms of shortness of breath on stairs.
