Patients often ask if some foods are “hairy”, such as seafood, dog meat, mutton, etc., will they cause wound infection after eating them? Is it not allowed to be eaten after surgery? According to Chinese medicine, the so-called “hairy food” refers to food that can cause or aggravate certain diseases, usually causing food allergies. Of course there are also some foods that can cause skin follicle infections. However, from the perspective of Western medicine, after surgery, it is just a matter of choosing a full-liquid, semi-liquid or normal diet according to the type of surgery. There is no obvious contraindication as to the type of food, that is to say, as long as you are not allergic, you can eat dog meat and mutton, and when your diet returns to normal, you can also eat some stimulating foods, such as garlic and chili. If you are allergic to a certain food, you should avoid it no matter what time it is. However, within 2-3 weeks after the surgery, as the gastrointestinal digestion and absorption ability has not fully returned to normal, it is better for the patient to eat some easy-to-digest food, too greasy food is not conducive to digestion, it is better to eat some light food, such as vegetables, fruits, porridge and so on.
