In clinic, I often hear patients ask about endometrium, they are afraid of thinness and thickness, so they pay special attention to endometrium. Is endometrium thinner or thicker?
What is normal thickness of endometrium?
Under normal conditions, thickness of endometrium should be between 5 and 10 mm. In different periods, thickness of endometrium will also vary greatly. In proliferative period, endometrium as a whole can reach about 10 mm, and during period of constipation, thickness of endometrium will be about 5 mm, and during menstruation, thickness of endometrium of women will be about 10 mm. In short, thickness of endometrium mainly changes with ovarian cycle.
The effect of too thin endometrium?1. Cause abnormal menstruation

Menstrual cramps are actually caused by endometrial rejection. If endometrium is too thin, endometrium will not separate normally, which will delay menstruation and reduce menstrual flow. In some patients, disease is more severe and causes amenorrhea.
2. Cause infertility
The thickness of endometrium is closely related to a woman's ability to conceive. If endometrium is too thin, fertilized eggs are difficult to implant, which greatly reduces ability to conceive. In presence of damage to endometrium, it is easy to cause intrauterine adhesions, which will also reduce ability to conceive and cause infertility.
3. Miscarriage
Most women with thin endometrium cannot successfully conceive a child, and some of them can conceive a child, but due to a poor internal environment, they cannot provide sufficient nutritional support for development of embryo, and chance of miscarriage is very high. , Recurrent miscarriage may develop.
What is effect of a thick endometrium?1. Abnormal periods can easily lead to long menstrual cycles and heavy menstrual flow. If left untreated, patients may develop iron deficiency anemia.

Secondly, fertilized egg cannot implant normally, which affects normal reproductive function.
Third, if endometrium is too thick, it will also cause various systemic diseases such as dizziness, headache, nausea, vomiting and so on. For safety reasons, it is recommended that patients go to hospital in time for treatment, so as not to delay disease.
So, endometrium cannot be too thin or too thick, it must be within normal range in order for it to be more useful for pregnancy.
