Thin endometrium and low menstrual flow, find the cause and then give appropriate treatment. In life, you can eat more soy products and dairy products, which contain more estrogen and progesterone. You can also eat black beans, wolfberries, gum and nuts, which can help thicken the endometrium and restore menstrual flow slightly. However, it is more important to find the cause and take appropriate treatment according to the cause: 1. Hyperprolactinemia: manifested as elevated blood prolactin, which will inhibit ovarian function and inhibit estrogen and progesterone production, resulting in thin endometrium and low menstrual flow, to be treated with specific drugs like bromocriptine. If the hyperprolactinemia is caused by pituitary tumor, usually pituitary tumor removal is also performed. 2. Organic lesions: Most often seen in patients with a recent history of uterine operations, such as curettage, abortion, etc. If the operation is more traumatic and damages the basal layer of the endometrium, it sometimes results in impaired endometrial proliferation, thin endometrium and low menstrual flow. Estrogen and progestin cycle replacement therapy is usually given first, with a slightly larger amount of hormones to thicken the endometrium. Hormones can cause damage to liver function, so liver function needs to be monitored regularly. However, sometimes treatment is not effective and further hysteroscopy is performed. Sometimes endometrial adhesions are found hysteroscopically and adhesiolysis is performed. In addition, female sex hormone six and thyroid function need to be checked. Endocrine diseases such as abnormal thyroid function and premature ovarian failure can affect ovarian function and cause a decrease in estrogen and progesterone secretion, leading to the condition, and the appropriate specific treatment should be given.
