Organ Prolapse in HEDS: How Common Is It and Why It Happens

Organ prolapse can be frightening, uncomfortable, and hard to talk about. For people with Hypermobile Ehlers-Danlos Syndrome, or HEDS, it can also feel confusing: why would the bladder, uterus, or rectum start to shift out of place, often at a younger age than expected?

The short answer is that HEDS affects connective tissue, the body’s built-in support system. When that support is stretchier or weaker than usual, the pelvic organs may not be held as firmly as they need to be.

Anyone with prolapse symptoms should speak with a clinician familiar with pelvic floor disorders and connective tissue conditions.

Pelvic support depends on muscles, ligaments, fascia, and healthy connective tissue.

How common organ prolapse is in HEDS

Research suggests that pelvic organ prolapse is more common in people with HEDS and hypermobility spectrum disorders than in the general population. Exact numbers vary because studies use different definitions, include different age groups, and may rely on self-reported symptoms rather than pelvic exams.

Across published studies of Ehlers-Danlos syndromes and hypermobility-related conditions, pelvic organ prolapse has been reported in roughly 13% to 75% of participants. That wide range does not mean the research is useless. It means prolapse risk can look very different depending on the group being studied.

For example, rates tend to be higher when a study includes:

• People who have given birth vaginally

• People referred to urogynecology or pelvic floor clinics

• Older adults

• People with more severe connective tissue symptoms

• Self-reported prolapse symptoms, such as pressure or bulging

  
  

In the general population, pelvic organ prolapse also becomes more common with age and childbirth history. What makes HEDS different is that prolapse may appear earlier, may happen with fewer traditional risk factors, or may occur alongside other issues such as bladder symptoms, pelvic pain, constipation, or hernias.

A key pattern in HEDS is not just that prolapse can happen, but that it may happen sooner or with less obvious strain than expected.

The organs most often affected

Pelvic organ prolapse happens when one or more pelvic organs shift downward because their support structures are not holding them in the usual position. In HEDS, the most frequently discussed types involve the uterus, bladder, and rectum.

The uterus, bladder, and rectum are the pelvic organs most often involved in prolapse.

Uterine prolapse

Uterine prolapse occurs when the uterus descends into the vaginal canal. Some people feel pelvic heaviness, pressure, a dragging sensation, or tissue bulging. Symptoms may feel worse after standing, lifting, or being active for a long time.

Not everyone with uterine prolapse has severe symptoms. Some notice only mild pressure. Others may have discomfort that affects walking, exercise, sex, or daily routines.

Bladder prolapse

Bladder prolapse, often called a cystocele, happens when the bladder pushes into the front wall of the vagina. It may come with urinary symptoms such as:

• Leaking urine with coughing, laughing, or exercise

• A frequent urge to urinate

• Trouble fully emptying the bladder

• Recurrent urinary tract symptoms

  
  

Bladder symptoms are common in HEDS even without clear prolapse, so a careful evaluation matters.

Rectal prolapse and rectocele

The rectum can be involved in more than one way. A rectocele happens when the rectum bulges into the back wall of the vagina. Rectal prolapse happens when part of the rectum slips down through the anus.

Symptoms may include constipation, pressure, incomplete emptying, or the need to press on the vaginal wall or perineum to pass stool. These symptoms can feel embarrassing, but they are real medical issues and are worth discussing with a trained clinician.

Why HEDS raises the risk of prolapse

HEDS affects collagen and connective tissue function. Collagen helps give strength and structure to ligaments, fascia, skin, blood vessels, and many other tissues. In the pelvis, these tissues act like a support network.

When that support network is more elastic or fragile, pelvic organs may have less resistance against downward pressure.

Pelvic floor care often includes education, strength, coordination, and pressure management.

Several factors can add to the risk.

Connective tissue laxity

Ligaments and fascia may stretch more easily in HEDS. Over time, this can make it harder for the pelvis to keep organs in place, especially during strain.

Pelvic floor muscle dysfunction

People often think prolapse only means “weak muscles,” but the pelvic floor can be more complicated in HEDS. Some muscles may be weak, while others are overactive or tense from trying to stabilize the pelvis. That tension can contribute to pain, constipation, and bladder symptoms.

Constipation and straining

Chronic constipation is common in many people with HEDS. Repeated straining increases pressure on the pelvic floor and can worsen rectocele, rectal prolapse, or other forms of pelvic organ descent.

Pregnancy and birth

Pregnancy adds weight and pressure to the pelvic floor. Vaginal birth can stretch muscles and connective tissues. These factors affect many people, but HEDS may reduce the tissue’s ability to recover and regain support.

Frequent coughing, heavy lifting, and high-impact activity

Anything that repeatedly increases abdominal pressure can place more load on pelvic support tissues. This does not mean movement is bad. It means people with HEDS may benefit from learning how to manage pressure during exercise, lifting, and daily tasks.

Prolapse symptoms can be subtle at first. Some people notice a feeling of heaviness at the end of the day. Others describe a tampon-like sensation, pelvic pressure, low back aching, or a visible bulge. Common symptoms include:

• Pelvic heaviness or dragging

• Vaginal or rectal bulging

• Urinary leaking or urgency

• Trouble starting or finishing urination

• Constipation or incomplete bowel emptying

• Pain with sex or pelvic exams

• Symptoms that worsen after standing or exertion

  
  

Symptoms do not always match the “grade” of prolapse found on exam. A mild prolapse can cause major distress, while a more advanced prolapse may cause fewer symptoms. Both experiences deserve care.

Treatment depends on symptoms, organ involvement, age, reproductive plans, overall health, and personal goals. Many people start with conservative care.

Options may include:

• Pelvic floor physical therapy with a clinician who understands hypermobility

• Constipation management and bowel routine support

• Bladder training or treatment for urinary symptoms

• A pessary, which is a removable support device placed in the vagina

• Activity changes that reduce repeated strain

• Surgery in selected cases when conservative care is not enough

  
  

For HEDS, surgical decisions need special care. Connective tissue fragility may affect healing, recurrence risk, and the choice of procedure. A urogynecologist, colorectal specialist, or pelvic floor team familiar with connective tissue disorders can help weigh the benefits and risks.

Tracking symptoms can make medical visits clearer and less overwhelming.

Organ prolapse in HEDS is common enough that pelvic pressure, bulging, bladder changes, or bowel symptoms should not be brushed off. Research reports vary widely, but the overall message is clear: connective tissue differences can make pelvic organ support more vulnerable.

The most often affected areas are the uterus, bladder, and rectum. The reasons are usually layered, with connective tissue laxity, pelvic floor dysfunction, constipation, pregnancy, birth, and pressure from daily activities all playing a part.

The right care often starts with being believed, getting a careful evaluation, and working with clinicians who understand that HEDS changes the usual rules of pelvic health.
