Uterine venting, which is when a woman’s vagina is loose and there is an overflow of gas. It may occur when a woman does exercises that increase her abdominal pressure, such as yoga, or during sexual intercourse. Uterine bleeding is mainly caused by excessive relaxation of the vaginal muscles during vaginal delivery, which does not restore the original elasticity or by relaxation of the pelvic floor muscles. In this case, women should do pelvic floor muscle rehabilitation or vaginal dumbbell training after the delivery, which will help for 2-3 cycles. Women should be careful not to do exercises that increase abdominal pressure, such as lifting heavy objects, squatting or constipation, and to eat more appropriate vegetables and fruits to keep the bowels open, which is also beneficial to the recovery of the condition.
