I don’t know when the folklore started to circulate that patients recovering from surgery should not eat “hairy food” because it will affect the wound healing. What are hairy foods? If someone has just undergone surgery, the most important question for patients and families is: what foods are good to eat, what foods should not be eaten, and should they avoid “hairy foods”? As surgeons, we often ask families what are “hairy foods”, and we hear that mushrooms, fish, shrimp, lamb, chicken and duck are “hairy foods”, but there is no uniform statement. Many patients, including family members, are really confused about what to eat, even to the extent of superstition, in fact, doctors want to say, as long as there is nutrition what to eat is not so important, and there is no effective evidence that hairy food affects wound healing. If you’re serious, it’s not even clear what hair is. The medical textbook does not say what “hair” is, and whether “hair” really exists is a question. What affects wound healing? There are many factors that affect wound healing, as long as the nutritional adequacy of what to eat is not the main factor, and really affect the wound healing factors are the following: 1, age: the older, the slower the wound healing. 2, high blood sugar: diabetic patients, more sugar in the blood, accompanied by vascular disease, will affect the wound healing. This is somewhat related to eating, with a history of diabetes wound itself healing ability is poor, if poor blood sugar control very affect wound healing (easy to induce infection) 3, poor nutrition: protein, vitamins, trace elements lack, can not provide the required nutrients for tissue regeneration, will delay wound healing. As long as the nutrition is enough, what to eat is not very concerned. 4, local infection: when the wound is infected, there is a lot of exudate, which will make the wound that is healing or the wound that has been stitched open, or cause the infection to spread and aggravate the injury, and the sharing of wound infection is related to obesity and diabetes. 5, poor local blood circulation: local blood circulation on the one hand to ensure the oxygen and nutrition needed for tissue regeneration, on the other hand, the absorption of necrotic material and control of local infection also play an important role. Therefore, it is necessary to promote blood circulation through moderate activities after surgery. 6, smoking: the combination of carbon monoxide and hemoglobin in the blood circulation of smokers reduces the ability to transport oxygen, and nicotine will make the surrounding blood vessels constrict and affect wound healing. Of course smoking is not allowed during hospitalization. 7, psychological factors: psychological stress, emotions will affect the function of the neuroendocrine and immune system, so that the wound healing slowed down. Therefore, to promote wound healing need to work on these aspects, rather than blindly jealous of “hair”. To break the superstition, out of the dietary misconceptions folk say that fish and shrimp are “hairy”, after surgery avoid eating, these claims lack scientific basis. In fact, fish and shrimp are high-protein food, as long as the doctor allows can eat, nutrition to keep up with the fast. Generally speaking, just after surgery due to anesthesia will fast for a period of time to ensure safety, non-gastrointestinal biliary and pancreatic surgery to be anesthesia effect can be normal diet after. Unless there are special conditions, the doctor will explain to the nurse whether to have a low-salt diet, low-protein diet, no-slag diet or liquid diet, etc. Since gastrointestinal, biliary and pancreatic surgery involves the digestive system, it is usually necessary to wait for the recovery of its function (ranging from 1-7 days) before gradually resuming the diet, during which the body’s needs will be ensured through parenteral nutrition. Promote postoperative recovery Postoperative patients should eat fresh food and try not to use processed food; food should be diversified and pay attention to nutritional balance. Food processing methods should be easy to digest such as stewing, boiling, steaming, etc., with less use of deep-frying and barbecue. Do not only drink soup without slag, nutrition are in the slag, less than 5% of the nutrition in soup, and not comprehensive. Water-soluble vitamins are easily destroyed after heating, you should eat both soup and slag. Nor should you eat meat without food and vegetables. In fact, post-operative wound healing is only a small part of post-operative recovery. Cooperating with the medical staff in treatment, early activity on the ground, adjusting the mentality and maintaining a happy mood are also important parts of promoting post-operative recovery.
