    An endometrial thickness of 20 mm may indicate the secretory phase of the menstrual cycle or the presence of pathological hyperplasia, which needs to be judged based on clinical symptoms. Common causes include physiological thickening, abnormal hormone levels, endometrial polyps, endometrial hyperplasia, endometritis, etc.

    1. Physiological thickening

    In women of childbearing age, during the secretory phase of the menstrual cycle (after ovulation to before menstruation), the endometrium can thicken to 10-16 mm, and in some people it can reach 20 mm. At this time, there are no symptoms such as abnormal bleeding or abdominal pain, which is a normal physiological phenomenon and does not require special treatment. It is recommended to review ultrasound regularly to observe changes.

    2. Abnormal hormone levels

    Long-term estrogen stimulation without progesterone antagonism may lead to excessive endometrial hyperplasia, which is common in patients with polycystic ovary syndrome and ovulation disorders. May be accompanied by oligomenorrhea or irregular bleeding. It is necessary to pass six sex hormone examinations and evaluations, and if necessary, use progesterone capsules, dydrogesterone tablets and other drugs to adjust the cycle.

    3. Endometrial polyps

    When local hyperplasia of the endometrium forms vegetations, ultrasound may show overall or partial endometrium thickening of up to 20 mm. Typical symptoms are intermenstrual bleeding or increased menstrual flow. The diagnosis requires hysteroscopy. Small polyps can be controlled by taking levonorgestrel sustained-release intrauterine system, while larger polyps require hysteroscopic resection.

    4. Endometrial hyperplasia

    Abnormally proliferated intimal glandular structures may become cancerous, especially those with atypical hyperplasia. It is common in perimenopausal women and manifests as irregular vaginal bleeding. The diagnosis requires pathological confirmation of endometrial biopsy, and treatment includes medroxyprogesterone acetate tablets and other drugs or endometrial resection.

    5. Endometritis

    Chronic inflammatory stimulation can lead to intimal congestion and edema, and ultrasound shows diffuse thickening with enhanced blood flow signals. Most patients have symptoms of lower abdominal pain and abnormal leucorrhea. Treatment requires antibiotics such as cefixime dispersible tablets combined with Gynecological Qianjin Tablets. In the acute stage, bed rest is required to avoid sexual intercourse.

    If you find that the endometrium is thickened, you should record the menstrual cycle time and avoid taking hormone drugs by yourself. It is recommended to increase the intake of dark green vegetables and whole grains and reduce high-fat diet. Do moderate yoga and other soothing exercises to improve pelvic blood circulation, but avoid strenuous running and jumping. If combined with abnormal bleeding, persistent abdominal pain or postmenopausal bleeding, prompt hysteroscopy and pathological biopsy are required.
