Diabetic patients can have plastic surgery, but only if the condition is stable and the specific situation is handled. Because diabetic patients often have some metabolic disorders, surgical incision is easy to be infected. Such patients should start monitoring blood sugar and urine sugar a few days before operation, and light patients can do some minor plastic surgery after controlling diet or adding oral hypoglycemic drugs to control blood sugar; Patients with moderate and severe diabetes need to switch to short-acting insulin before operation, so that the preoperative fasting blood glucose can be stably controlled below 10 mmol/L for several days. Contraindications of different plastic surgery are different. Some are absolute contraindications that surgery cannot be performed under any circumstances; Some patients can be operated after a period of treatment or avoiding inappropriate operation period, that is, relative contraindications. * * * The same contraindications are as follows: (1) those with severe diabetes, heart disease, hyperthyroidism and hypertension are not controlled. (2) pregnant women. (3) Patients with inflammatory lesions in or around the operating area (those who need to be cleaned). (4) mental patients. (5) those who expect too much from the operation. In order to carry out the operation smoothly and recover well after operation, the doctor should be informed of the current medication situation truthfully. Because some drugs will aggravate or reduce the effect of anesthetics; Some drugs will accelerate or slow down the absorption or excretion of drugs after operation, or conflict with drugs used after operation; Other drugs can cause difficulty in hemostasis and excessive bleeding during and after operation. If patients with cardiovascular diseases take aspirin and compound Danshen tablets orally, these drugs can inhibit platelet aggregation, reduce blood viscosity, prolong bleeding time, and it is difficult to stop bleeding during surgery. Some drugs can affect wound healing, such as glucocorticoid. If you tell the doctor about these drugs, the doctor will arrange the operation reasonably according to the situation. If you can operate, you will be told whether you need to stop taking medicine, adjust the dosage and usage of the medicine, or change the medicine.
