Endometrial thickening can be divided into simple thickening of the endometrium and thickening of the endometrium with lesions. Simple thickening of the endometrium mostly has no significant effect on the body, while a small percentage may cause abnormal menstruation, anemia, or affect fertility. Endometrial thickening with lesions may be associated with endometrial polyps and endometrial cancer, which may also cause certain effects. A. Simple thickening of endometrium 1. Abnormal menstruation: It can be manifested as irregular vaginal bleeding, scanty menstruation or prolonged heavy vaginal bleeding after a period of amenorrhea. Generally, asymptomatic people do not need any treatment, and heavy menstruation can be treated with oral short-acting contraceptives, which will make the thickened endometrium thinner, and the amount of menstruation will gradually decrease; 2. anemia: if there is heavy bleeding or dripping menstruation, it may lead to anemia, and shock may occur in serious cases; 3. affect fertility: due to the thickening of the endometrium, the endometrium is continuously affected by estrogen, without progesterone to The endometrium is in a state of hyperplasia due to the thickening of the endometrium, so that the endometrium is continuously affected by the action of estrogen without progesterone to counteract it, and lacks the transformation of the cyclic secretion period, and the patient will experience long-term non-ovulation. The endometrium is too thick and not easy to fertilize eggs, so fertility can be reduced; 4, other: endometrial hyperplasia is often due to endocrine disorders, which can easily make women appear dull skin and long spots. Endometrial hyperplasia should be treated with progesterone in time. Usually, if treatment is not timely, it will gradually progress to atypical hyperplasia and even endometrial cancer. 2. Endometrial thickening with lesions 1. Patients with endometrial polyps will experience excessive menstrual flow and even anemia, which, if left untreated for a long time, will lead to infertility, uterine cavity infection, chronic pelvic inflammatory disease, and even the possibility of malignancy, and endometrial polyp removal is recommended; 2. The presence of endometrial cancer has a greater impact on the organism, and sometimes endometrial cancer, even if treated, will result in disease recurrence Sometimes endometrial cancer may recur and progress even after treatment, which affects the survival time of women.
