First of all, let’s start with platelets, the normal value should normally be above 100,000, and if it’s at 90,000, it should be possible to do it if the scope of the surgery is not considered too extensive. However, if the surgery is extensive, it should be considered with caution. Otherwise, there may be diffuse bleeding during the surgery, and the recovery will be very slow, and the risk of the surgery is very high, so I personally very much do not recommend the surgery. Second, heart disease. If there is myocardial hemorrhagic necrosis, or if the heart rate is irregular after an EKG, if the heart rate is below 50 and doesn’t increase after stimulation, or if there is a tachycardia of more than 100 beats, all of these are not suitable for surgery. The heart is the engine of the body, if a car engine has problems, the impact must be very great, so I also do not recommend surgery, beauty is more important, but it must be no more important than life, as a doctor, you must keep the bottom line and not cross the red line. Thirdly, the problem of high blood pressure. If the diastolic blood pressure is higher than 90 and the systolic blood pressure is higher than 140, surgery is not recommended. If it can be stabilized and controlled by taking medication, surgery can be considered only after discussing with the attending doctor. Fourth, I do not recommend surgery if you have diabetes or abnormal impairment of liver or kidney function. Fifth, surgery is not recommended for infectious diseases, such as AIDS, syphilis, active stage of hepatitis B and C, or suffering from tuberculosis, which need to be determined by preoperative examination, and the surgery should be safety-oriented.
