Reduce Urine Leakage by 50% With an 8% Weight Loss

A study reported in the January 29, 2009 issue of the New England dripping faucetJournal of Medicine (NEJM) reported overweight women who reduced their body weight by 8% over a 6 month period cut the frequency of their incontinence episodes by at least half, compared to a control group who did not lose a significant amount of weight.

At the outset of the study the women had a minimum of at least 10 incontinence episodes per week. The women averaged 24 episodes of incontinence per week. The women were age 53 on average and had a mean body mass index (BMI)  of 36. (Calculate your body mass index-BMI-here)

The Weight Reduction Program

The meal plan consisted of a 1200-1500 calorie/day diet with no more than 30% of the calories from fat. To make simplify the diet some participants used Slimfast supplements for 1-2 meals per day and then ate a regular meal for their third meal. Sample meal plans were given to the women.

The exercise plan consisted of gradual increase in physical activity, such as brisk walking, to reach a goal of 200 minutes/week (this equates to 30 minutes per day of brisk walking–can be done continuously or in three 10 minute stretches).

The control group was not given a meal plan or exercise plan but still managed to lose1.6% of their body weight over the 6 month study period.

Why overweight causes or worsens incontinence

Simple physics.

Imagine a balloon filled with air. If you place a 15-pound lead anvil on this balloon, chances are, no matter how hard you try to hold the balloon shut, it will either leak air out the stem, or simply burst. On the other hand, if you place a 0-pound “anvil” on the balloon, it is much more likely to retain its air.

obesity The “spare tire” or “tummy” or “flap” that hangs over your belt is called a “pannus” in medical terms. A pannus acts like a lead anvil in relation to your bladder. The weight of the pannus exerts pressure on the bladder and “squeezes” urine out the urethra as if you were squeezing toothpaste out of a tube by exerting pressure on the tube with your hand.

Even the “strongest” of bladder muscles cannot withstand the forces exerted by a large enough pannus.

Pelvic Floor Muscle Training (PFMT)–Kegels

PFMT or Kegel exercises strengthen the muscles around and underneath the bladder. Doing Kegel exercises consistently, 10 sets of 10 per day for at least 6 weeks significantly reduces or eliminates urine leakage, regardless of weight lost. For more information on how to do Kegels, click here.

The Results: PFMT works; PFMT + weight loss doubles the results

Women in the weight-loss group had an average of 7.8 kg (about 15 lbs) weight loss in 6 months; the control group lost an average of 1.6 kg (about 3 lbs). The weight-loss group experienced a 47% reduction in incontinence episodes, compared to the group who did PFMT only, without the 8% weight reduction. Interestingly, with just PFMT, the women in the “non-weight-loss” group still reduced the frequency of their incontinence episodes by 28%.

Even small reductions in weight can improve incontinence: As little as a 5 or 10-pound weight loss reduces the frequency of urine leakage episodes.

Weight loss to reduce leakage of urine or gas is another example of sustainable health care: Low-cost intervention with “megaphone-like” results.

    Hey,

    My mother in law is 53 incontinent, over 240 lbs & has a large pannus. Also her 3 daughters inherited the pannus as well (& are over 300lbs) & I worry about bladder control in my wife & her younger sister. If the Pannus is causing this should surgery be an option. I feel bad for mother in law because she wets 3 times a day & I dont think she wants to talk to anyone about it.

      Hi Wilson,

      If surgery is contemplated the best option would be something that would reduce the weight, such as bariatric surgery. If there is no weight loss, incontinence surgery has a very high failure rate.

      Thank you for reading the blog and commenting.
