A small uterus is a congenital condition in which the uterus is underdeveloped. Some cases of uterine hypoplasia can be treated with traditional Chinese medicine or western medicine to a greater or lesser extent, but some cases are very difficult to make them grow again. The common causes of uterine dysplasia are congenital diseases and endocrine causes, such as estrogen and progesterone deficiency, so it is possible to stimulate the uterus to grow again by giving supplemental estrogen or progesterone, but it may take a longer course of treatment. Chinese medicine believes that a small uterus can be attributed to a lack of innate kidney energy or nutritional deficiencies, so it can be treated by oral tonifying the kidneys, nourishing the yin, and strengthening the spleen, commonly used medicines include ripened rhubarb, Chinese wolfberries, Zihechuan, Cistanchis, Cuscuta, Atractylodes Macrocephala, Chasteberry, and so on, and it can be adjusted by taking proprietary medicines, such as Heche Dazhou Pills, which are suggested to be taken at hospitals as prescribed by the doctor. In conclusion, the small size of the uterus also depends on the degree of smallness of the uterus, if it is only slightly small, through early treatment can play a certain degree of efficacy, if it is too small, infantile uterus is very difficult to let it develop again. In any case, women should strengthen their nutrition, especially during puberty when they are growing up, and should not go on diets to lose weight and so on.
