Thin endometrium does not have a particular food that can thicken the endometrium; the food has some nutritional value but does not have any preventive or therapeutic effect on the disease. The endometrium can be clinically divided into the functional layer and the basal layer. Normally, with the cyclic changes of estrogen and progesterone in the body, the endometrium of the functional layer can undergo cyclic proliferation and shedding. When the menstrual period is over, a woman’s functional layer of endometrium is completely shed, which can lead to thinning of the endometrium, and no special treatment is needed at this time. Some patients need to undergo purging due to abnormal uterine bleeding or incomplete abortion, etc. The surgery can damage the endometrium, resulting in a thin endometrium, which can be treated with oral estrogenic drugs, commonly used are estradiol valerate tablets and so on. It should be noted that, if the patient has the need to use drugs need to be used under the guidance of a professional physician, so as not to blindly use drugs lead to adverse consequences.
