Posterior position of the uterus can be corrected by changing the sleeping position and exercise. The position of the uterus is divided into three groups, anterior, median and posterior. They usually do not cause discomfort and do not need to be corrected. When the posterior position of the uterus is quite severe, it tends to cause menstrual blood to accumulate in the uterine cavity during menstruation, which is not easily eliminated, causing painful menstrual symptoms such as lower abdominal distension and lumbar bottom pain. This position of the uterus is not conducive to sperm entering the uterus through the cervix, resulting in a much lower chance of conception. For women who are preparing for pregnancy and have been infertile for a long time, this condition needs to be treated. Adjust the sleeping position, try to sleep on your back, and do more exercises, such as sit-ups, kneeling exercises, and pelvic floor muscle training. It usually takes a long time to persist and can achieve certain results.
