A thin uterine lining can usually recover after an abortion. There are two main ways to help the uterine lining recover, which are different for different cases of first abortion and multiple abortions. 1. First time abortion: the damage to the uterine lining is generally small, and can be gradually relieved through the cyclical self-repair of the uterine lining. Generally, after 3 normal menstrual periods after the abortion, the uterine lining will gradually thicken, and can be significantly relieved. 2. Multiple abortions: The damage to the endometrial lining is great, which can easily cause the endometrial lining to become thin, and can also easily cause adhesions in the uterine cavity. It is difficult to rely on the endometrial self-repair ability to make it thicker after multiple abortions, it is recommended to consult a doctor in a timely manner, under the doctor’s instructions to take medication to regulate, generally using estrogen-progestin combination, commonly used drugs, such as drospirenone ethinyl estradiol tablets. Therefore, the ability of the uterus to recover after abortion is related to the damage state of the uterine lining, and contraceptive measures should be taken to avoid damage to the uterine lining from multiple abortions. Regular ultrasound examination is needed after abortion, pay attention to postoperative care, avoid exertion, and eat more nutritious food.
