What should I do if my period starts right after surgery?

　　"Menstruation" usually refers to a woman's monthly period. In general, the onset of menstruation immediately after surgery may be caused by postoperative hormonal fluctuations, coincidence with the natural menstrual cycle, post-surgical stress response, uterine cavity stimulation due to surgical procedures, or abnormal blood clotting function. It is recommended to seek medical attention promptly, identify the underlying cause, and follow a doctor’s guidance for appropriate symptomatic management. Detailed explanations are as follows:

　　1. Postoperative hormonal fluctuations: Surgical trauma can disrupt hormone levels in the body, leading to early onset of menstruation. It is important to rest adequately, avoid emotional stress, maintain a regular sleep schedule, and eat light, nutritious meals to help stabilize hormone levels gradually.

　　2. Coincidence with physiological cycle: If the timing of surgery overlaps with the natural menstrual cycle, this occurrence is simply a normal physiological phenomenon. Change sanitary products frequently, maintain external genital hygiene, avoid tub baths, and prevent postoperative wound infections.

　　3. Postoperative stress response: Surgical stress can affect the hypothalamic-pituitary axis, disrupting the menstrual cycle and causing early menstruation. Reduce physical activity after surgery, ensure sufficient sleep, and relieve stress through relaxing activities such as listening to music to minimize stress responses.

　　4. Uterine cavity surgical stimulation: Procedures such as abortion or hysteroscopy directly stimulate the endometrium, potentially causing withdrawal bleeding. Follow medical advice to use hemostatic medications such as tranexamic acid tablets, Baogong止血granules (Bao Gong Zhi Xue Ke Li), or Yunnan Baiyao capsules. Additionally, take cefuroxime axetil tablets to prevent infection.

　　5. Abnormal coagulation function: Surgery may impair normal blood clotting mechanisms, or the patient may already have pre-existing coagulation disorders, resulting in heavier-than-normal menstrual bleeding. Immediately recheck coagulation function and, under medical supervision, use medications such as vitamin K1 injection, etamsylate injection, or aminomethylbenzoic acid injection to improve clotting ability.

　　In daily life, closely monitor menstrual flow and duration; inform your doctor promptly if bleeding exceeds the usual range. Avoid spicy, stimulating, or blood-activating foods. Increase intake of protein-rich foods to promote wound healing. Keep the surgical wound clean and dry, and strictly adhere to postoperative care instructions provided by your healthcare provider.
