The pelvic floor muscles sit between your hips and sacrum. Like a bowl, they hold several organs like the bladder, colon, and uterus. A weakening of the pelvic floor can be caused by a variety of things, for example, pregnancy. Symptoms of weak pelvic floor muscles include incontinence or the shifting of pelvic organs inside the body. Pelvic floor physiotherapy then is designed to strengthen these pelvic floor muscles through specific exercises and improve the symptoms or eliminate them completely. Improvements can often be seen after just five to seven sessions.
