After lung nodule surgery, patients should pay attention to maintaining balanced nutrition, avoiding spicy and stimulating food, increasing rest time, exercising appropriately, and reviewing in time. 1. Balanced nutrition: After surgery, patients need to consume more nutrients during the recovery process, so they should take more protein and nutrient-rich foods, such as eggs, milk, lean meat and so on. 2. Avoid spicy and stimulating food: spicy and stimulating food is stimulating to the lungs and incision, which is not conducive to postoperative recovery. 3. Pay attention to rest: patients who have just finished lung nodule surgery should strengthen the rest, avoid staying up late, overwork, so as not to affect the recovery of the wound. 4. Appropriate exercise: appropriate exercise will help the recovery of lung function. 5. Regular checkups: You should follow the doctor’s instructions and go to the hospital for regular checkups to assess the postoperative recovery or whether there is any recurrence of the disease.
