A prolapse is when the an organ moves and bulges out of the vagina.
A prolapse usually happens due to a weakened pelvic floor as the pelvic muscles support the organs and hold them in place. They can become weakened from pregnancy, childbirth, being overweight, frequent straining and age.
If the prolapse is mild you may benefit from pelvic floor exercises and lifestyle changes such as loosing weight.
You could also be treated with a vaginal pessary to give support to the prolapsing organs.
