Low menstrual flow after an abortion usually does not need to be addressed if there are no future fertility requirements, as low menstrual flow at this time usually does not affect health, but may only affect fertility. If the menstrual flow is low and there are future fertility requirements, the patient may need to be evaluated. A common assessment is hysteroscopic assessment, which requires looking at the condition of the endometrium and the presence of uterine adhesions. There are two ways to deal with this: 1. Pharmacological approach: If there are no adhesions in the uterine cavity, but only a thinning of the thickness, pharmacological treatment, such as estrogen and progesterone, can be used to promote the growth of the endometrium, and can also be supplemented with Chinese herbs to thicken the endometrium and increase the menstrual flow naturally; 2. Surgical approach: If there are uterine adhesions, surgery may be needed to cut open the adhesions and restore the structure of the uterine cavity. After the structure of the uterine cavity is restored, drugs will be used to make the endometrium grow, which will hopefully make the endometrium recover or get better and the menstrual flow will become more. The location of the pregnancy is in the endometrial layer of the uterus, and the abortion requires clearing out the tissue and may also clear out the endometrium along with it, which can lead to injury to the endometrium. Generally, the more abortions you have, the greater the chance of injury and the more serious the injury, but some people may have a more serious injury with one abortion, which may lead to a lower menstrual flow. Since the lining is a very important source of menstruation, if the damage to the lining becomes thinner, the amount of menstruation may become less.
