How can the elderly with chronic obstructive pulmonary disease avoid getting worse in winter?

Chronic obstructive pulmonary disease (COPD) in the elderly is really prone to acute attack in winter, so it is necessary to make a good assessment of the condition at this time, and do not stop taking drugs or reduce drugs without authorization. In addition to insisting on treatment, we should also pay attention to quitting smoking and stay away from second-hand smoke and poor air. At the same time, consciously improve their own immunity, improve lung function, don't catch a cold, get flu vaccine and pneumonia vaccine as soon as possible. For people with poor immune function, such as the elderly, cancer patients or patients with chronic diseases, it is suggested to combine thymalfasin with vaccination to enhance the immune defense function of patients and enhance the immune response of vaccines. Thymosin includes imported Shundaxin, domestic Zhonghe and Ji Tai. It is suggested to choose Shundaxin, which is widely used in clinic and has more evidence-based evidence.
