Pelvic floor

A sling of muscle at the base of the pelvis that holds the bladder, bowel and uterus in place, controls continence, and takes part in sex. It is the most consequential group of muscles most people never think about.

Pelvic floor problems are extraordinarily common and extraordinarily under reported. A large proportion of women experience urinary leaking at some point, and a smaller but substantial proportion live with a prolapse or with pelvic pain. Very few of them raise it. The reasons are familiar: the symptoms are embarrassing, they appear gradually, they are widely assumed to be permanent, and they are still described in most conversations as an inevitable consequence of childbirth or age. None of that is accurate. Most pelvic floor symptoms improve with correct treatment, and a good proportion resolve.

What the muscles actually do

The pelvic floor closes the bottom of the pelvis. Three passages run through it: the urethra, the vagina and the anus. The muscles hold those passages closed at rest, relax to let them open, and tighten reflexively at the moment abdominal pressure rises, which is what stops a cough or a jump from producing a leak. They also support the bladder, uterus and rectum from below, and they contract rhythmically during orgasm.

That list explains why a single group of muscles can produce such different complaints. Weakness shows up as leaking, as a feeling of heaviness, or as reduced sensation. Overactivity shows up as pain, as difficulty starting to urinate, as constipation, or as an inability to tolerate penetration. Poor coordination, which is the most common finding of all, can produce almost any combination of the above. The anatomy page sets out the structure in more detail.

Two very different problems

The distinction between a weak pelvic floor and an overactive one matters more than anything else in this section, because the treatment is close to opposite. A weak floor needs graded strengthening, with enough load and enough consistency to change muscle over months. An overactive floor needs the opposite: down training, breathing work, release techniques and often manual therapy, with strengthening added only later if it is needed at all.

The reason this goes wrong so often is that both can cause leaking. A muscle that is held short and tight all day is also a muscle that is tired and cannot generate a strong reflex contraction when it matters. Someone in that position who is told to do a hundred squeezes a day will usually feel worse. If exercises have been tried properly and symptoms have not improved after several weeks, or have got worse, that is a reason to be assessed rather than a reason to try harder. The page on an overactive pelvic floor describes what that presentation looks like.

Where to start

Anyone with no symptoms who simply wants to train the muscles can begin with the technique page and then follow the eight week programme. The technique page matters more than the programme: a large share of people who believe they are doing pelvic floor exercises are in fact bracing the abdominal wall, squeezing the buttocks, or bearing down, and none of those does anything useful.

Anyone with symptoms should read the relevant topic first. Leaking with coughing, sneezing or exercise, a dragging or bulging sensation, pain with penetration and difficulty emptying the bladder or bowel each point in a different direction.

After birth

Pregnancy loads the pelvic floor for months regardless of how the baby is delivered, and vaginal birth adds direct stretch and sometimes injury to muscle or nerve. Recovery is real and usually good, but it is not automatic and it is not fast. The page on the pelvic floor after childbirth covers what normal recovery looks like, which symptoms should prompt a referral rather than a wait, and why the six week check is a starting point rather than a discharge.

Getting help

Pelvic health physiotherapy is the treatment with the strongest support for stress urinary incontinence, for mild to moderate prolapse and for many kinds of pelvic pain. It involves an assessment, usually including an internal examination with consent, followed by a treatment plan that is adjusted over several appointments. The page on pelvic health physiotherapy describes what happens and how to be referred.

Surgery exists for prolapse and for some kinds of incontinence, and it can be the right answer, but in most guidelines it comes after conservative treatment rather than instead of it.
