What causes endometrial shedding?

Endometrial exfoliation is a normal physiological phenomenon caused by hormonal changes and periodic growth and exfoliation of the endometrium. Endometrial exfoliation is a normal physiological phenomenon that usually occurs during a woman's menstrual cycle. The following is a detailed analysis of the causes of endometrial exfoliation: 1. Normal stages of the menstrual cycle Women's menstrual cycle includes three stages: proliferation, secretion and menstruation. During the menstrual cycle, the endometrium sloughs off and is expelled from the body, which is the main component of menstruation. 2. Changes in hormone levels Hormones secreted by the ovaries play a key role in the growth and sloughing of the endometrium. During the menstrual cycle, estrogen and progesterone levels change, resulting in thickening and sloughing of the endometrium. Endometrium sloughs off when estrogen levels drop and progesterone levels are insufficient to maintain endometrial growth.3. Periodic growth and sloughing of the endometrium Endometrium undergoes growth and sloughing during each menstrual cycle. During proliferation, the endometrium thickens and prepares for implantation of a fertilized egg. If there is no pregnancy, the endometrium will fall off during menstruation and form menses. 4. Other factors such as emotional stress, changes in living habits, weight fluctuations, and diseases may also affect hormone levels, thus affecting endometrial shedding. It is important to note that endometrial shedding is a normal physiological process, but abnormal menstrual bleeding, pain, or other discomfort symptoms may indicate health problems. The following are some of the conditions that may require attention: Abnormal uterine bleeding: excessive, too little, irregular, or prolonged bleeding may be a sign of endometrial polyps, uterine fibroids, endocrine disorders, etc. Dysmenorrhea: Severe dysmenorrhea may be associated with endometriosis, adenomyosis, etc. Other symptoms such as painful intercourse, abnormal leucorrhea, etc. may also indicate gynecological problems. If there are any doubts or concerns about menstrual cycles or endometrial shedding, it is recommended to consult a doctor for a detailed evaluation and diagnosis. Depending on the circumstances, a doctor may perform physical, laboratory or other further evaluations to determine if there are underlying health problems and recommend treatment accordingly. Maintaining a healthy lifestyle, such as eating a balanced diet, exercising moderately, and reducing stress, is also important for maintaining a normal menstrual cycle and women's health. Key messages: Endometrial shedding is a normal physiological phenomenon during the menstrual cycle, caused by changes in hormone levels and periodic growth and shedding of the endometrium. If abnormal symptoms occur, consult your doctor for evaluation and diagnosis.
