Bladder prolapse is very common. Roughly 1 in 3 women will have some degree of pelvic organ prolapse in their lifetime, and the bladder dropping into the vaginal wall (called a cystocele) is the most frequent type. A 2024 systematic review pooling data from studies worldwide put the overall prevalence at 30.9%, though the number climbs to about 41% when based on physical examination rather than self-reported symptoms. Many women with mild prolapse never realize they have it.
Prevalence by Age Group
Bladder prolapse can technically happen at any age, but the burden falls overwhelmingly on women over 50. Incidence peaks twice: once in the early-to-mid 50s and again in the late 60s. Women aged 60 to 69 have the highest incidence rate in the United States, at roughly 1.5 to 1.8 new cases per 1,000 women each year. Among women aged 70 to 79, the rate of seeking medical care for symptomatic prolapse reaches 18.6 per 1,000.
Studies estimate that 41% to 50% of women over 40 have some measurable degree of prolapse. The U.S. population is aging, and projections suggest the number of women living with prolapse will increase by about 50% by 2050.
Many Cases Never Cause Symptoms
Having anatomical prolapse on an exam doesn’t mean you’ll feel anything wrong. In one study of women with confirmed Stage 2 through Stage 4 prolapse, about 78.5% reported noticeable symptoms, meaning roughly 1 in 5 women with a measurable prolapse had no bothersome complaints at all. Mild cases, where the bladder has shifted slightly but hasn’t reached the vaginal opening, often go completely unnoticed.
When symptoms do appear, they typically include a feeling of pressure or fullness in the pelvis, a sensation of something bulging at the vaginal opening, difficulty fully emptying the bladder, and stress incontinence (leaking urine when you cough, sneeze, or lift). Symptoms tend to worsen after long periods of standing or by the end of the day.
What Raises Your Risk
Vaginal childbirth is the single strongest risk factor. The risk of pelvic organ prolapse roughly doubles after a second vaginal delivery, and two vaginal births are associated with an eightfold increase in the odds of developing urinary incontinence alongside prolapse. The strain of delivery stretches and sometimes tears the muscles and connective tissue that hold the bladder in place. Cesarean delivery carries far less risk.
Body weight matters too. Women who are overweight have at least a 36% higher risk of clinically significant prolapse compared to women at a normal weight. For women classified as obese, the risk jumps to at least 47% higher. The extra abdominal weight creates constant downward pressure on the pelvic floor, gradually weakening its support.
Menopause accelerates the process. Estrogen plays a direct role in maintaining the strength of pelvic connective tissue by regulating how collagen is built and broken down. After menopause, falling estrogen levels thin the vaginal walls and weaken the ligaments that support pelvic organs. Up to 40% of postmenopausal women experience some form of pelvic floor disorder, whether that’s prolapse, incontinence, or both.
Other contributors include chronic coughing (from smoking or lung disease), repeated heavy lifting, chronic constipation, and a family history of prolapse. Connective tissue strength has a genetic component, which is why some women develop prolapse after a single pregnancy while others never do despite multiple births.
How Prolapse Is Staged
Doctors grade prolapse on a scale from 0 to 4 using a standardized measurement system. Stage 0 means no prolapse at all. Stage 1 means the bladder has dropped slightly but remains well above the vaginal opening. Stage 2 means it has descended to within about a centimeter of the opening. Stage 3 means tissue protrudes beyond the opening but the vagina hasn’t fully turned inside out. Stage 4 is a complete eversion, where the vaginal walls are essentially turned inside out.
Most women who are diagnosed fall into Stage 1 or 2, which are the mildest forms. Stage 3 and 4 are less common and almost always symptomatic.
How It’s Managed
Not every prolapse needs treatment. Mild, asymptomatic cases are often monitored over time with no intervention. Pelvic floor exercises (Kegels) can slow progression and reduce symptoms in early stages by strengthening the muscles that act as a sling beneath the bladder.
For women with bothersome symptoms, the two main options are a pessary or surgery. A pessary is a silicone device inserted into the vagina to physically support the bladder. It’s non-surgical, removable, and effective: in a randomized trial comparing the two approaches, 76% of women using a pessary reported meaningful improvement at two years, compared to 82% of women who had surgery. The difference is smaller than most people expect, which is why pessaries are a reasonable first choice for many women.
About 13% of women in the United States will undergo surgery for prolapse at some point in their lives, and roughly 29% of those women will eventually need a second procedure. Surgery typically involves lifting the bladder back into position and reinforcing the vaginal wall. Recovery takes several weeks, and doctors generally recommend avoiding heavy lifting for two to three months afterward.
Why It’s Underreported
The 30.9% global prevalence figure likely underestimates reality. When researchers relied on questionnaires alone, prevalence came in at about 25%. When they physically examined women, it jumped to nearly 42%. Many women with mild prolapse don’t recognize their symptoms as prolapse, attribute pelvic heaviness to aging, or feel embarrassed to bring it up. The gap between self-reported and exam-based numbers suggests that millions of women are living with undiagnosed prolapse that could be managed if identified.
