Introduction
In general, high estrogen levels accompanied by thin endometrium may be caused by factors such as irregular lifestyle, excessive mental stress, endometrial damage, polycystic ovary syndrome (PCOS), or hyperprolactinemia. When such conditions occur, it is recommended to seek medical attention promptly to identify the underlying cause and receive appropriate treatment. In daily life, it is important to maintain a regular作息 (sleep-wake cycle), avoid excessive fatigue, eat a balanced diet, and reduce intake of high-sugar and high-fat foods.
Under normal circumstances, high estrogen levels accompanied by thin endometrium may be caused by irregular lifestyle habits, excessive mental stress, endometrial damage, polycystic ovary syndrome (PCOS), or hyperprolactinemia. When such conditions occur, it is recommended to seek medical attention promptly to identify the underlying cause and receive appropriate treatment. Detailed analysis is as follows:
1. Irregular Lifestyle
Chronic late-night sleeping and reversed day-night rhythms disrupt endocrine regulation. Although estrogen levels may be elevated, the endometrium responds abnormally to hormones and fails to thicken properly. Adjust sleep schedules by ensuring 7–8 hours of sleep each night, maintaining consistent bedtime and wake-up times, and avoiding staying up late.
2. Excessive Mental Stress
Prolonged anxiety and tension can affect hypothalamic-pituitary function, leading to hormonal imbalance and inhibited endometrial proliferation. Stress can be relieved through physical exercise, listening to music, or other relaxation techniques. Maintaining emotional stability is essential, and psychological counseling may be sought when necessary.
3. Endometrial Damage
Repeated induced abortions or intrauterine procedures may damage the basal layer of the endometrium. Even with sufficient estrogen, the endometrium struggles to repair and thicken, often accompanied by reduced menstrual flow. Under medical guidance, medications such as estradiol valerate tablets, conjugated estrogens tablets, or estradiol drospirenone tablets may be prescribed. In severe cases, hysteroscopic adhesiolysis may be required.
4. Polycystic Ovary Syndrome (PCOS)
Ovarian dysfunction leads to disordered estrogen secretion. Long-term anovulation deprives the endometrium of cyclical stimulation, resulting in thinning, along with symptoms such as infrequent menstruation and hirsutism. Under medical supervision, treatments may include ethinylestradiol cyproterone acetate tablets, drospirenone ethinylestradiol tablets, or spironolactone tablets. Weight management and regular physical activity are also important.
5. Hyperprolactinemia
Elevated prolactin levels suppress ovarian function and impair estrogen activity, leading to impaired endometrial proliferation. Under medical guidance, medications such as bromocriptine mesylate tablets, vitamin B6 tablets, or cabergoline tablets may be used. Avoid prolonged breast compression and minimize stimulation.
In daily life, it is important to maintain a regular schedule and avoid excessive fatigue; eat a balanced diet with reduced intake of high-sugar and high-fat foods; engage in moderate exercise to improve overall health; and undergo regular gynecological check-ups for early detection and timely management of issues.
