Thin endometrium without menstruation needs to be treated in conjunction with the cause of the condition, which is usually treated with hormonal medication and surgery. Thin endometrial lining is a relatively common condition, mostly due to the decline in hormone levels, which is insufficient to allow the endometrial lining to grow to a level that allows menstruation; it may also be caused by multiple uterine operations, resulting in damage to the endometrial lining. If the hormone level drops, then you need to complete the sex hormone test and follow the doctor’s instructions to choose hormone drugs to increase the endometrial lining, such as estradiol valerate tablets plus progesterone, ethinyl estradiol cyproterone tablets and so on. If the adhesions are caused by repeated uterine operations, then hysteroscopic surgery can be performed to separate the adhesions, after which they will gradually recover. If the endometrium is found to be thin, you can consult a doctor in time and choose the appropriate way to deal with it.
