A prolapse happens when the pelvic muscles and tissues can no longer support these organs because the muscles and tissues are weak or damaged. This can lead to symptoms such as a feeling of heaviness in your vagina, especially when standing, or feeling a bulge when you wipe. Many women are embarrassed to talk to their doctor about their symptoms—or think that their symptoms are normal—however, pelvic floor physical therapy can improve these symptoms and work as a preventative measure as well.
