Endometrial thinning caused by abortion is mainly caused by excessive force during curettage or by destruction of the basal layer of the endometrium due to scraping too deeply. This condition is very difficult to treat and the outcome is often unsatisfactory, and there are two main treatment options for patients. First, hormonal drugs are used for treatment. In clinical practice, estrogen plus progestin is mostly chosen for cyclical conditioning. Estrogen can stimulate the growth of the endometrium. Generally, we choose to use supplemental Jiale, using about 4-6mg per day, and add progesterone for treatment in the second half of the cycle for 3 months, and observe the effect. Second, you can choose to use traditional Chinese medicine for treatment. Traditional Chinese medicine can be chosen to tonify the kidney and activate the blood, for example, you can use Kuntai capsule, deer fetus cream, together with Shao abdominal stasis granules, etc., which also need to be treated for 3-6 months.
