A prolapsed uterus occurs when the uterus slips downward from its normal position and pushes into or through the vaginal canal. This happens when the muscles, ligaments, and connective tissues that hold the uterus in place become too weak or stretched to do their job. Prevalence estimates range from 3 to 6% of women overall, but that number climbs to roughly 50% in women who have given birth vaginally, and many cases are mild enough that they never cause noticeable symptoms.
How the Uterus Stays in Place
The uterus is held in the pelvis by a hammock-like system of muscles and ligaments working together. The most important muscular component is the levator ani, a broad sheet of muscle that forms the pelvic floor. Parts of this muscle attach to the vaginal walls, the area between the vagina and rectum, and the tissue around the anus, keeping the opening in the pelvic floor closed and supporting everything above it.
On the ligament side, the cardinal and uterosacral ligaments form a three-dimensional web that connects the lower uterus, cervix, and upper vagina to the sacrum (the triangular bone at the base of the spine) and the pelvic sidewalls. This complex maintains vaginal length and keeps the vaginal axis horizontal, essentially holding the uterus in a stable position over the pelvic floor muscles below it. When either system fails, whether through muscle injury, ligament stretching, or connective tissue deterioration, the uterus can descend.
What Causes It
Vaginal childbirth is the single biggest risk factor. The process of labor and delivery can stretch, tear, or damage the pelvic floor muscles and the nerves that control them. The risk goes up with each vaginal birth, with delivery of a large baby, with difficult or prolonged labor, and with being older at the time of your first delivery.
Menopause plays a major role as well. The drop in estrogen weakens pelvic connective tissue over time, which is why prolapse becomes far more common in the years after menopause. Beyond these two primary drivers, several other factors raise the risk:
- Obesity, which places chronic downward pressure on the pelvic floor
- Chronic constipation or habitual straining during bowel movements
- Chronic coughing, including from smoking or lung disease
- Repeated heavy lifting
- Prior pelvic surgery
- Family history of weak connective tissue
Hispanic and white women also have a statistically higher incidence than other groups, suggesting a genetic component to connective tissue strength.
What It Feels Like
Mild prolapse often causes no symptoms at all. Many women have some degree of descent without ever knowing it. When the uterus drops far enough, though, the most distinctive symptom is a sensation of heaviness, fullness, or pressure in the pelvis, sometimes described as feeling like something is falling out. Some women can feel or see tissue bulging at or beyond the vaginal opening.
Because the uterus sits between the bladder and the rectum, its descent can pull on or press against both. This means prolapse frequently causes urinary problems: difficulty fully emptying the bladder, a frequent or urgent need to urinate, or urine leaking when you cough, sneeze, or lift something. Bowel symptoms are common too, including constipation, a feeling of incomplete emptying, or needing to press against the vaginal wall to have a bowel movement. Discomfort or a loss of sensation during sex is another frequent complaint. Symptoms tend to worsen after long periods of standing or by the end of the day, and they improve when lying down.
Stages of Prolapse
Doctors grade severity using a system called the Pelvic Organ Prolapse Quantification (POP-Q), which measures how far the uterus has descended relative to the hymen:
- Stage I: The lowest point of descent is still more than 1 cm above the hymen. Usually no symptoms.
- Stage II: The lowest point is within 1 cm above or below the hymen. Symptoms like pressure or a bulging sensation often begin here.
- Stage III: The uterus extends more than 1 cm past the hymen but is not fully outside the body.
- Stage IV: Complete eversion, meaning the uterus has descended entirely through the vaginal opening.
How It’s Diagnosed
Diagnosis is straightforward and done during a pelvic exam. Your doctor will insert a speculum and then ask you to bear down forcefully, as if you were trying to have a bowel movement. This bearing-down action (called a Valsalva maneuver) temporarily increases pressure in the abdomen and reveals how far the uterus and vaginal walls descend. The doctor examines the front and back vaginal walls separately by retracting one wall at a time while you bear down again. If prolapse isn’t visible during an exam on the table, you may be asked to stand and repeat the maneuver, since gravity can make the descent more obvious.
Nonsurgical Treatment
For mild to moderate prolapse, or for women who prefer to avoid surgery, a pessary is the primary nonsurgical option. A pessary is a removable device, typically made of silicone, that you insert into the vagina where it provides structural support to hold the uterus in place. The most commonly used type is a ring pessary, which is O-shaped and works well for mild to moderate prolapse. For more advanced cases, options include the Gellhorn (a disc with a stem), the donut (a thicker ring), and the cube (which uses gentle suction against the vaginal walls).
Pessaries need to be properly fitted by a healthcare provider. One that’s too small can fall out during a bowel movement, while one that’s too large will feel uncomfortable. Once fitted, most women wear them during the day and remove them at night, or keep them in continuously with periodic removal for cleaning. They don’t cure prolapse, but they can effectively manage symptoms for years.
Pelvic Floor Muscle Training
Structured pelvic floor exercises can reduce prolapse symptoms in women with stage I, II, or III prolapse. A trial published in The Lancet found that women who completed a physiotherapist-guided program of five in-person sessions over 16 weeks reported significantly fewer prolapse symptoms than a control group, with improvements lasting at least 12 months.
The program went beyond simple daily Kegel exercises. Women were also taught to consciously contract their pelvic floor muscles before and during any activity that increases abdominal pressure, like lifting, coughing, or sneezing. This “brace before you strain” habit may protect the pelvic floor from further damage over time. The researchers noted that lifelong attention to pelvic floor exercise, combined with intentional muscle engagement during physical strain, has the potential to prevent prolapse symptoms from developing or worsening.
Surgical Options and Recovery
When symptoms are severe or don’t respond to conservative measures, surgery is effective. The specific procedure depends on the extent of the prolapse and whether you want to preserve the uterus. Options include repairing the weakened tissue that supports the uterus (sometimes with surgical mesh for reinforcement), suspending the uterus back into position, or removing the uterus entirely through a hysterectomy combined with repair of the surrounding support structures.
About 80% of prolapse surgeries remain successful after 10 years. Between 10 and 20% of women will have some degree of recurrent descent, but it’s usually mild enough that no further intervention is needed. Only 2 to 3% of women require a repeat surgery.
Recovery takes one to six weeks depending on how extensive the repair is. Most women return to work within two to six weeks. During recovery, you’ll need to avoid placing anything in the vagina for six weeks (no tampons or sexual intercourse) and avoid lifting anything over 15 pounds for two to six weeks.
