A thin endometrium can lead to low menstrual flow, and a thin endometrium may be caused by a hormonal deficiency in the ovaries. Endometrial insufficiency should undergo relevant endocrine tests and different measures should be taken depending on the patient’s condition. If the endometrium is only slightly thinner than normal, the possibility of conception is high. The main cause of thin endometrium is endocrine disorders, such as low estrogen level, insufficient progesterone, ovulation disorders and growth hormone deficiency; the local factor is endometrial damage. In this case, you can take drugs to supplement estrogen, such as progesterone and tonic acid. Diet should eat more soybeans, milk, papaya, soy milk, etc., all of which have the effect of supplementing estrogen. Traditional Chinese medicine is mainly used to tonify the kidney and qi in order to regulate the thickness of the lining and increase the amount of menstruation.
