Q: I’m on my period, but I just had an appointment with my doctor, what should I do? A: “The girls who have consulted the cosmetic surgery program will definitely be asked if they are in their physiological period?” Some girls lie that they have passed in order to be beautiful quickly, which is actually a very dangerous practice. Before performing medical aesthetic surgery, doctors will recommend that women during the physiological period should not undergo medical aesthetic surgery, and wait until after the physiological period, this is why? Specifically, the period to do cosmetic surgery have these hidden dangers: 1, immunity decline during menstruation, due to endocrine imbalance, the body’s resistance to viruses is significantly lower than usual, will increase the chances of infection. If it is more traumatic surgery, will also extend the recovery period, and is prone to post-operative complications. 2, easy to cause infection Due to the imbalance of endocrine secretion in women’s body during menstruation, it is easier than usual to have body fatigue, swelling and pain, mood swings, and the body’s resistance to pathogenic bacteria is significantly lower than normal. 3. Prolonged bleeding time In normal human body, there exists fibrinase with coagulation effect and fibrinolytic enzyme with hemolysis effect, and these two substances are kept in balance so that the blood in human body can circulate normally. However, during menstruation, this balance is broken, fibrinolytic enzymes are activated, and the blood in the body will be in a state that is not easily coagulated. Women’s normal menstrual blood are not easy to coagulate. 4. Increased vascular fragility Because blood does not clot easily, once a blood vessel rupture occurs (such as a surgical injury), even a small vessel rupture may lead to serious consequences. If there is more than one bleeding or a hematoma is formed because of wound bleeding, it will prolong the recovery time. In addition, if the hematoma area becomes a base for bacterial growth, it can also lead to infection. Therefore, if there are no special circumstances, all medical aesthetic procedures that can be performed at a completely optional date should be avoided during menstruation, especially for procedures that are extensive and take a long time to perform, and should be performed at a later date. According to clinical observation, if women can have surgery around 5 to 10 days after menstruation (i.e., the period between menstruation), it is not only safe, less bleeding, but also less infections and other complications.
