Endometrial thickening is an abnormal hyperplasia of the endometrium, mainly due to inflammation, endocrine disorders or stimulation by certain drugs, causing excessive hyperplasia of the endometrium. Endometrial thickening tends to cause excessive menstruation and prolonged periods in women. Most of them do not heal easily on their own and require a timely visit to a gynecologist for ultrasound and sex hormone test to confirm what causes endometrial hyperplasia. After taking some biopsies and confirming that it is a benign hyperplasia, surgery can be used as soon as possible to avoid other pathological changes caused by long-term hyperplasia. During the treatment period, it is necessary to pay attention to rest and avoid straining. Eat a light, easily digestible, high vitamin and high nutrition diet.
