Many fruits can be eaten after lung surgery, such as the usual apples, pears, grapes, watermelon, tomatoes and bananas, etc. These fruits contain a large amount of vitamin C and fruit acids, which are good for the healing of the incision, and have a great effect on the recovery of the lung after surgery. After lung surgery, do not eat fruits with irritating smell, such as durian, or fruits that cause allergies, such as peach, which have irritating taste and cause allergies, which can lead to frequent coughing. Frequent and violent coughing after lung surgery is extremely detrimental to the healing process and can lead to infection or poor healing, which can cause difficulties in later treatment.
