Introduction
"Menstruation" refers to a woman's monthly period. Having menstruation twice a month may be related to physiological factors, or could result from pathological conditions such as endometrial hyperplasia or endometriosis. Treatment should target the specific underlying cause, including medication and, if necessary, surgical intervention. Besides the aforementioned causes, uterine fibroids might also be responsible. After diagnosis, it is important to maintain personal hygiene and avoid resuming sexual intercourse too early to prevent cross-infection.
Menstruation, commonly referred to as "menstrual period," typically occurs once a month. Having two menstrual periods in one month may be related to physiological factors, or could result from pathological conditions such as endometrial hyperplasia or endometriosis. Treatment should target the specific underlying cause, including medication and, when necessary, surgical intervention. The following is a detailed analysis:
1. Physiological Causes
Hormone levels, particularly sex hormones, fluctuate significantly during ovulation, which may lead to partial shedding of the endometrium. This can result in bleeding outside the regular menstrual period. As ovulation ends, the bleeding usually resolves on its own without requiring special treatment.
2. Pathological Causes
1) Endometrial Hyperplasia
Excessive estrogen stimulation can cause abnormal proliferation of the endometrium, disrupting the menstrual cycle and leading to irregular uterine bleeding or prolonged menstruation. After diagnosis, patients should follow medical advice to take medications such as medroxyprogesterone acetate tablets, progesterone capsules, or dydrogesterone tablets. In severe cases, surgical intervention may be required, followed by appropriate postoperative care.
2) Endometriosis
When endometrial tissue grows into the muscular wall of the uterus (adenomyosis), it causes significant enlargement of the uterine cavity, impairing normal uterine contractions. This leads to symptoms such as increased menstrual flow, prolonged periods, and general fatigue. Treatment options—such as conservative surgery or semi-radical surgery—are selected by the physician based on the patient's condition. Postoperative management aims to restore endometrial health and promote recovery.
In addition to the above causes, uterine fibroids may also be responsible. After diagnosis, patients should maintain good personal hygiene and avoid resuming sexual intercourse too early to prevent cross-infection.
