Why do I leak when I sneeze?

Why does a sneeze make me leak?

Because a sneeze is a sudden push from inside. When you sneeze, cough, laugh, lift something or jump, the muscles of your belly squeeze down and the pressure on your bladder jumps for a moment. The NIDDK (National Institute of Diabetes and Digestive and Kidney Diseases, part of the US National Institutes of Health (NIH)) calls the leak that follows stress incontinence: an action puts pressure on the bladder and some urine escapes [2]. Here "stress" means physical pressure, not worry.

Normally that pressure is not a problem. The urethra (the tube that carries urine out) is held closed by a ring of muscle, the sphincter, and supported from below by the pelvic floor, a sling of muscles and tissue at the bottom of the pelvis. MedlinePlus, the health library of the US National Library of Medicine, explains that stress incontinence happens when the tissue that supports the urethra gets weak [3]. The bladder itself is usually fine. It is the "door" that does not stay shut under a sudden push.

You are far from alone. The NIDDK estimates that about half of all women experience urinary incontinence at some point [1], and MedlinePlus notes that stress incontinence is common in women [3].

What weakens the pelvic floor?

Usually it is not one thing but a mix of life events and everyday habits. These are the ones the NIDDK and MedlinePlus list [2] [3]:

Is it stress incontinence or an overactive bladder?

It is worth knowing which one you have, because the fixes are different. The NIDDK describes the two most common types like this [1] [2]:

Many women have both at once (mixed incontinence). A doctor can tell them apart, often with the help of a bladder diary.

What actually helps stress leaks?

Pelvic floor muscle training comes first. It has the strongest evidence. A Cochrane review (summary by the UK National Institute for Health and Care Research) pooled 31 trials with 1,817 women. In the trials on stress incontinence, about 56% of women who trained reported a cure, against about 6% of women who did not train: roughly 8 times more likely. Cure or improvement was reported by 74% against 11% [5]. Most trials followed women for less than a year.

Pelvic floor exercises are often called Kegels. The NIDDK explains that strong pelvic floor muscles hold urine better than weak ones, and that a health care professional can check that you are squeezing the right muscles [4]. A pelvic floor physical therapist can also teach the technique. Do not practice the squeezes while urinating.

Other steps the NIDDK lists for stress leaks [4]:

• Losing weight if you are overweight: it can mean fewer leaks, and avoiding weight gain may prevent them.
• A pessary: a soft plastic device placed in the vagina to help with stress leaks. There is also a disposable, tampon-like device that can stay in for up to 12 hours, handy for a workout.
• Bulking injections: a gel or paste injected near the sphincter to help it close.
• Surgery: the most common one for women is a sling that supports the urethra. The NIDDK notes that complications can occur in some women.

Small habits help too: treating constipation, quitting smoking (and the cough that comes with it) and keeping caffeine and alcohol in check. Our FemiCore review lists the full set of everyday habits from the NIDDK.

Can a supplement like FemiCore help with sneeze leaks?

Here is the honest answer: no supplement has the kind of evidence pelvic floor training has for stress leaks.

FemiCore is a daily capsule with cranberry, bearberry, mimosa pudica, berberine and five probiotic strains. According to the maker, it supports bladder control by helping rebalance the urinary microbiome, the bacteria that live in the bladder. The study our review cites for that idea (published in the journal mBio in 2014) compared women with and without urgency incontinence, not stress incontinence, and it found a difference in bacteria, not proof that changing them stops leaks [6]. We did not find studies of FemiCore itself.

So if your leaks happen mainly when you sneeze, cough or laugh, start with the pelvic floor. If you also get sudden urges, or you simply want to add daily support on top of the basics, FemiCore is one option, and it comes with a 60-day money-back guarantee. Our full FemiCore review goes through each ingredient, the research behind it, possible side effects and the price.

When should I see a doctor about leaks?

MedlinePlus puts it simply: contact your provider if you have symptoms of stress incontinence and they bother you [3]. There is no need to wait until it gets worse, and leaks are a normal thing to bring up.

The NIDDK says to get care right away if you [2]:

• Cannot pass urine at all.
• See blood in your urine.
• Have pain or burning when you urinate, or other signs of a bladder infection.
• Need to go eight or more times a day.

Before the visit, keep a bladder diary for a few days: what you drink, when you go, when you leak and what you were doing (sneezing, lifting, running). It helps the doctor tell stress leaks from urge leaks.
