Urine leakage during pregnancy vomiting is a pelvic floor dysfunction disorder, also known as prenatal urinary incontinence. Because of the pressure on the low pelvis caused by the enlargement of the uterus after pregnancy, the pelvic floor muscles and ligaments become relaxed, and the urethral sphincter also becomes relaxed, so the increase in abdominal pressure during pregnancy vomiting leads to urinary incontinence. Pregnant women can do Kegel exercises, that is, the movement of shrinkage and anal lifting can reduce the symptoms to a certain extent. Pregnant women can also exercise their pelvic floor muscles by doing maternity balls, or do pregnancy yoga if their body allows them to do so, which can reduce prenatal leakage. After delivery, you should go to a pelvic floor rehabilitation center for pelvic floor assessment and treatment in time, which can reduce the symptoms.
