On the seventh day of taking dydrogesterone, menstrual flow suddenly increased.
Dydrogesterone may refer to dydrogesterone tablets. Experiencing a sudden increase in menstrual flow on the seventh day of taking dydrogesterone tablets is generally a normal phenomenon, but it could also be due to endometrial hyperplasia or insufficient dosage. Patients can improve the condition through medication or increasing the dosage as appropriate. Specific analyses are as follows:
1. Normal phenomenon
Dydrogesterone tablets belong to the class of progestin medications and are commonly used clinically to treat conditions caused by endogenous progesterone deficiency, such as dysmenorrhea, endometriosis, secondary amenorrhea, dysfunctional uterine bleeding, and premenstrual syndrome. The sudden increase in menstrual flow may result from hormonal effects causing endometrial shedding and vaginal bleeding, indicating the onset of menstruation. This is a normal physiological response and does not require special treatment.
2. Endometrial hyperplasia
Due to individual differences in constitution, some people may have endometrial hyperplasia. After taking dydrogesterone tablets, this condition may lead to extensive endometrial shedding, resulting in a sudden increase in menstrual flow. If heavy menstrual bleeding persists, patients may take medications under a doctor's guidance to alleviate symptoms, such as Yunnan Baiyao Capsules or caffeic acid tablets.
3. Insufficient dosage
Under normal circumstances, dydrogesterone tablets can help control bleeding. If patients are taking these tablets to treat the aforementioned conditions but use an inadequate dosage, it might lead to increased menstrual flow. It is recommended to adjust and increase the dosage under medical supervision.
Besides the above reasons, increased menstrual flow could also be caused by cervical inflammation, threatened miscarriage, cervical cancer, or other conditions. For an accurate diagnosis, patients are advised to undergo a thorough medical examination at a hospital to identify the specific cause and receive targeted treatment.
