The thickness of a woman’s endometrium varies at different times of the menstrual cycle. If the endometrial lining becomes thin, it can affect the menstrual cycle as it affects the ability to get pregnant. Therefore, women with a thin endometrium need to have it thickened in a timely manner. For patients with thin endometrium and no history of endometrial surgery, it is usually caused by endocrine disorders in the body and a decrease in ovarian function, resulting in a decrease in estrogen and progesterone, for which hormonal drugs can be taken to stimulate the growth of endometrium, for example, progesterone, progesterone tablets and other drugs can be taken to regulate and treat the condition. The medication should be taken in strict accordance with the instructions or under the guidance of the clinician, and should not be interrupted at will. These drugs can effectively increase the level of estrogen and progesterone in the body, thus stimulating the growth of the endometrium and achieving a thickening effect. Thin endometrium is associated with repeated abortions and inductions. If the thin endometrium is caused by surgical damage, medication can be administered, but it has limitations and may not be as effective as desired. Therefore it is important to avoid abortions and other uterine surgeries.
