After pneumothorax surgery, you can consume more protein-rich food to promote the recovery of the incision, but you should avoid spicy and stimulating food. Since protein is an important part of human tissues and organs, and the energy needed by patients undergoing surgery is increased compared to usual due to preoperative fasting, etc., you can consume more protein-rich foods such as soybeans, dairy, meat, etc. after having pneumothorax surgery. Moreover, you should avoid eating spicy and stimulating food, which is highly irritating and easy to induce coughing, and may cause aspiration and incision disintegration, which is not conducive to the recovery of the condition. At the same time, must quit smoking and avoid alcohol, so as to recover faster.
