Pneumothorax patients should never drink alcohol: first of all, alcohol has a strong stimulating effect on the throat, which may cause pharyngitis. Once pharyngitis occurs, coughing will occur, and the pressure in the chest cavity will increase when a person coughs, which is likely to aggravate the pneumothorax or lead to the recurrence of pneumothorax. Secondly, drinking alcohol will lower the immune system, and people are prone to catching a cold when their immune system is low. Once a cold occurs, it is an upper respiratory tract infection, which may also lead to coughing, and coughing can lead to aggravation or recurrence of pneumothorax. In addition, the absorption function of the gastrointestinal tract of people who drink alcohol is not good, and at this time, immunity is not only low, but also malnutrition will occur, and the body’s resistance will also decline along with it. In addition, it is easy to get drunk when drinking, and accidents can easily occur when drunk, which is also very unfavorable to the recovery of pneumothorax.
