What causes a 17-year-old girl to have her period three times in one month?

A 17-year-old girl having three menstrual periods in one month may be due to either non-disease factors or underlying medical conditions, such as pelvic inflammatory disease or endometrial polyps. Treatment should target the specific cause. Details are as follows:

1. Non-disease factors

If a 17-year-old female frequently takes contraceptive drugs, it may lead to irregular and frequent menstruation. Usually, no special treatment is required other than discontinuing the medication.

2. Disease factors

1) Pelvic inflammatory disease (PID)
Pelvic inflammatory disease may affect organs such as the ovaries, fallopian tubes, uterus, and vagina, impairing their normal function and causing menstrual irregularities. It is recommended to follow medical advice and use medications such as ofloxacin capsules, metronidazole tablets, or clindamycin capsules to eliminate pathogens, control infection, and relieve symptoms.

2) Endometrial polyps
Endometrial polyps can interfere with the normal shedding of the uterine lining, leading to changes in the menstrual cycle and causing a 17-year-old girl to menstruate three times in one month. Treatment options include hysteroscopic surgery, total hysterectomy, or subtotal hysterectomy, as directed by a physician.

In addition, other conditions such as uterine fibroids, ovarian cysts, or hyperthyroidism may also cause menstruation three times in one month. Patients are advised to seek timely medical evaluation at a hospital to determine the exact underlying cause.
