It is learned from major hospitals in Wuhan that with the sudden change of temperature, the number of influenza-like cases has increased sharply, and the number of patients with acute "chronic obstructive pulmonary disease" in middle-aged and elderly people has also increased sharply.

Hook, a professor of respiratory medicine at Wuda People's Hospital, said that "chronic obstructive pulmonary disease" is called chronic obstructive pulmonary disease, which is commonly referred to as chronic bronchitis and emphysema. The main reason is smoking, followed by dust, oil fume and air pollution.

According to the latest estimate of WHO, "chronic obstructive pulmonary disease" ranks fourth among the causes of death in the world after heart disease, cerebrovascular disease and acute lung infection, and is called "the fourth invisible killer" together with AIDS. Every year, the number of patients with chronic obstructive pulmonary disease in China reaches 35 million, and the death toll reaches 654.38+0 million.

Hook said that the clinical diagnosis of "chronic obstructive pulmonary disease" is often omitted because it is not included in the routine physical examination. At the same time, the early symptoms of "COPD" are not obvious. Many patients don't know that they are sick at all, but wait until they have difficulty breathing, go upstairs to gasp, or repeatedly cough and expectorate when they go to the hospital for examination.

Hook suggested that long-term smokers or people who live in polluted environment for a long time should have a lung function examination every year. It is also suggested that people should not smoke, and pay attention to keeping indoor air circulating and fresh in their work and life.
