The lining is the soil in which the embryo is planted and develops, and plays an important role in the pregnancy process. Many people will ask when monitoring ovulation in the clinic: How thick does the lining have to be before it is ready? Why is my lining so thin? Can drinking soy milk and eating black beans make the lining grow? Under normal circumstances, the lining of the uterus thickens with the development of follicles and the rise of estrogen, while some people’s lining of the uterus is always very thin, and cannot be thickened by the development of follicles or even by the use of topical medications, so how thin is the lining considered thin? Some people say 5mm, some say 6mm, most opinions tend to be less than 7mm, if you want to say the most suitable endometrial thickness for pregnancy, generally believe that 8-14mm is more appropriate. So the question is, what exactly is the cause of a thin uterine lining? The consequences of a thin endometrium are, like the picture below, fewer periods, abnormal color, and difficulty in getting pregnant. Currently, the most reliable clinical treatments for thin endometrium are as follows: In conclusion, the diagnosis and treatment of thin endometrium has always been a difficult one, but don’t despair, because even for endometrium with thickness less than 5mm, there are cases of successful pregnancies and deliveries, and there are also some new treatments, such as bone marrow stem cell transplantation, which may be applied to the clinic in the future, and the above mentioned treatments do not work for everyone. The treatments mentioned above are not effective for everyone, and dietary treatments such as drinking soymilk all day long have not been proven to have a significant effect. Hysteroscopy is necessary, but at this stage there is a lack of effective means of endometrial function testing and evaluation indexes. So once found endometrial thin, the correct method is not to look for a variety of remedies, but for different causes to actively solve the problem, in addition, in the normal life, must maintain good habits, try to avoid unclean sex, pay attention to contraception, avoid repeated abortions, to reduce the unnecessary operation of the uterine cavity, so that no matter whether it is the state of nature or the use of medication I believe that there will be a good effect, right!
