I had a thyroid removed. What happened to my period?

The irregular menstruation after cutting a thyroid gland may be due to post-surgical stress reaction, hypothyroidism and so on.
1. Post-surgical stress reaction: It may be because the organism is in a state of tension due to damage after undergoing surgery, which causes anxiety and nervous reaction, and at this time, it may cause the patient to experience symptoms of irregular menstruation.
2. Hypothyroidism: After removing a thyroid gland, it may cause hypothyroidism, which leads to insufficient secretion of thyroid hormones, which may cause symptoms of irregular menstruation such as excessive menstruation, amenorrhea and prolonged menstrual period.
If you have irregular menstruation after the removal of one thyroid gland, you should seek timely and standardized treatment.
