Normal females start their menarche from puberty until they go through menopause around. Having normal and regular menstruation is a sign of a woman’s good health. We will now reveal why you should not have surgery during menstruation? If there is more bleeding during menstrual surgery The dynamic balance between normal condition coagulation and anticoagulation is the key for the body to maintain the state of blood flow in the body and prevent blood loss. The coagulation system, anticoagulation and fibrinolytic system, blood vessels and blood cells constitute the four basic links of coagulation and anticoagulation balance in the process of maintaining the normal circulation of blood in the body. The high fibrinolytic activity of menstrual blood due to the fibrinolytic effect of fibrinolytic enzymes leads to the liquefaction and discharge of menstrual blood and tissue fibers, and usually menstrual blood does not coagulate. When surgery is performed during menstruation, this effect turns beneficial to harmful, resulting in an organism with a tendency to bleed. In addition, the inevitable tissue trauma during surgery activates and depletes a large number of coagulation factors, and the fibrinolytic system is relatively hyperactive. Surgery during this period results in more intraoperative wound bleeding, which affects the surgical operation; more postoperative bleeding can cause secondary problems such as airway compression. Increased pain sensitivity during menstruation Studies have shown that women are more sensitive to pain during menstruation. The pattern of activation of pain-related brain regions is altered when one is menstruating; however, the relationship between sex hormones and nociception is not well understood. In addition, dysmenorrhea associated with menstruation may interfere with the diagnosis of postoperative complications and delay treatment. In some patients, excessive preoperative stress leads to endocrine dysfunction and early menstruation, which is best suspended if detected in time. However, the menstrual period is not an absolute contraindication to surgery. If a patient suddenly gets sick and injured during menstruation and has to undergo emergency surgery, he certainly cannot wait. Especially for a few gynecological procedures, such as uncontrollable severe functional uterine bleeding, the only way to stop the bleeding is to remove the uterus, and even during menstruation, emergency surgery is necessary. Slow healing recovery The immune function of the body decreases during menstruation, which affects the improvement of the disease and the healing of the incision. The decrease in the body’s resistance makes the incision, the respiratory system and the urinary system susceptible to infection, which is detrimental to the patient’s recovery. If you really want to operate during menstruation, you should prepare well before surgery; be careful during surgery and try to stop bleeding thoroughly; and observe closely after surgery to prevent infection. For patients with irregular menstrual cycles, a gynecologic consultation is required to manually adjust the menstrual cycle if necessary to reduce medical risks. For patients who are ready to be admitted, the surgeon must ask for a detailed menstrual history and also find out when the patient’s last menstrual period was. The most appropriate time for surgery is three to five days after the menstrual period has cleared.
