Pelvic floor, leaking and exercise: what weight loss fixes and what it does not

Leaking when you cough, laugh, jump or lift is common, embarrassing and mostly fixable. Weight loss helps more than most women expect. A few minutes of daily squeezes does the rest.

Why weight matters

The pelvic floor is a sling of muscle holding up the bladder, womb and bowel. Extra weight sits on it all day. Pregnancy, birth and the menopause each weaken it further. The NHS urinary incontinence page lists obesity among the causes of stress incontinence, the leaking that comes with a cough, sneeze, laugh or lift.

Losing weight takes the load off. In the PRIDE trial, women who lost about 8% of their body weight over six months had 47% fewer leaking episodes a week, against 28% fewer in the comparison group. That is one of the quickest wins of a weight loss medicine, and one nobody mentions in the leaflet.

The exercise

Pelvic floor exercises, sometimes called Kegels, strengthen the sling. NICE recommends at least three months of supervised pelvic floor training as the first treatment for stress incontinence. Most women can do the basic version alone.

Sit, stand or lie. Imagine stopping yourself passing wind, then stopping a wee at the same time. That lift and squeeze is the pelvic floor. Your bottom, thighs and stomach should stay relaxed, and you should keep breathing.
Slow squeezes: lift, hold for up to 10 seconds, release fully, rest for 4 seconds. Ten of those.
Fast squeezes: lift hard and let go at once. Ten of those.
Three times a day. Tie it to something you already do: the kettle, the school run, brushing your teeth.

It takes about three months of daily practice to see a change, which is where most women give up. The free NHS-recommended Squeezy app sets reminders and counts. If you cannot feel the muscle at all, or cannot tell if you are doing it, a pelvic health physiotherapist can check in a single appointment. Self-referral is available in many NHS areas and your GP can refer in the rest.

The knack

Squeeze and lift right before you cough, sneeze, laugh or lift something heavy. This is called the knack and it stops a leak in the moment while the strength builds. Breathing out as you lift does the same during exercise.

Exercising without making it worse

Breathe out on the effort. Never hold your breath to lift. Holding pushes down on the pelvic floor.
Skip jumping, skipping and running until you can do them dry. Walking, cycling, swimming and strength work with the knack are all fine.
Choose squats and bridges over sit-ups and crunches, which push down hard. The dead bug in our strength guide works the core without the strain.
Lift lighter and slower rather than heavy and fast until the floor is strong.
Empty your bladder before a session, but do not go "just in case" all day. That trains the bladder to signal early.

Urge, not stress

Leaking on the way to the toilet, needing to go urgently and often, or going more than eight times a day is urge incontinence, which is a bladder problem rather than a floor problem. Caffeine, fizzy drinks and alcohol all make it worse. Bladder training, which means stretching the gap between visits by a few minutes each week, is the NHS first step. Many women have both kinds, and the pelvic floor exercises help both.

Prolapse

A feeling of heaviness, dragging or a bulge at the vaginal entrance, worse at the end of the day or after standing, can be a prolapse, where the bladder, womb or bowel drops into the vagina. It is common after childbirth and after the menopause, and weight loss and pelvic floor exercises help the milder stages. The NHS prolapse page describes it. A pessary, a small device fitted by a GP or physio, supports the mild to moderate cases and lets you exercise.

When to see someone

Three months of daily exercises with no improvement, any prolapse symptoms, pain, blood in urine, or leaking that stops you leaving the house all deserve an appointment. Pelvic health physiotherapy is free on the NHS. Women wait an average of years before asking. There is no reason to be one of them.

Questions

Does losing weight stop leaking?

It reduces it a lot. In the PRIDE trial, women who lost about 8% of their body weight had 47% fewer leaking episodes a week. Pelvic floor exercises fix most of the rest.

How do I do pelvic floor exercises?

Squeeze as if stopping wind and a wee at the same time, without tightening your bottom or thighs and without holding your breath. Ten slow holds of up to 10 seconds, then ten fast squeezes, three times a day. Expect three months before you notice a change.

Can I exercise if I leak?

Yes. Walk, cycle, swim and do strength work with the knack: squeeze and lift right before each effort and breathe out as you lift. Skip jumping and running until you are dry.

Is pelvic health physiotherapy free?

Yes, on the NHS. Many areas take self-referrals and your GP can refer in the rest. One appointment can confirm whether you are doing the exercises right.
