Functional uterine bleeding in women, also known as dysfunctional uterine bleeding, occurs not due to organic lesions in the reproductive system but due to abnormalities in the function of the gonadal axis, leading to hormonal imbalances and dysfunctional uterine bleeding. This condition is generally unrelated to procedures like abortion or curettage. In some cases, it is triggered by issues such as delayed recovery of ovarian function following an abortion, excessive fatigue, or abnormalities in thyroid and adrenal gland functions, causing dysfunction of the gonadal axis. To address this issue, it is essential to first conduct tests, including a hormone panel and assessments of thyroid and adrenal gland functions, to identify the cause of the dysfunctional uterine bleeding and provide appropriate treatment.
