Post-operative diet should pay attention to the following points: 1. Foods that affect vascular activity Generally, foods and drugs containing herbal ingredients that activate blood circulation and resolve blood stasis, such as angelica, safflower and Chuanxiong, have the effect of accelerating blood circulation, which may cause the wound that has been hemostatic to bleed again after consumption, or even local hematoma, prolonging recovery time. In addition, alcohol also has a blood-activating effect, while tobacco interferes with the normal diastolic function of the tiny blood vessels, so alcohol and smoking should be avoided in the short term. 2, spicy and too hot food After eating spicy or too hot food, the local and systemic body temperature will rise, increasing metabolism and accelerating blood circulation, and there will also be dryness, sweating and other reactions, as sweat often contains bacteria, which is not conducive to the healing of the wound, and the moist environment will easily lead to local bacterial reproduction, increasing the probability of postoperative infection and aggravating scar growth. 3, uneaten seafood, tropical fruits and other foods Crab, shrimp and other crustaceans in seafood, mangoes, pineapples and other tropical fruits can easily lead to allergies. When allergy occurs, the skin will be red, swollen, rash, molting and itching, which is not conducive to wound healing and tissue repair. 4. Foods that are hard and require hard chewing Food around the mouth and lips must be eaten soft and cool after surgery to reduce facial expression activities because muscle activity and overheating can lead to wound bleeding, delayed wound healing, etc. The folklore of avoiding soy sauce or darkly pigmented foods has no scientific basis. For friends with normal nutritional status, it is recommended to eat more vegetables and fruits in general, a light diet, less meat dishes and heavy flavors such as sour, spicy and salty, and stay away from smoking, alcohol and night life.
