I have stress urinary incontinence. What can I do?

Im 16 and i pee when I laugh. Not all the time. Idk why, but sometimes I do. I know its something that might've gone through, but I want to know how to stop it. Help

Hmmm, you're so young for SUI and you say it doesn't happen all the time?
Maybe it's more of an immature bladder...do you let your bladder get too full before you empty? Maybe try to go more frequently.
As someone else said, keep your weight in the normal range.
And you're not too young to start doing kegel exercises. Here's a link with a description of how to do them.

I suggest you see a doctor. I have stress incontinence when I have a UTI or kidney stones.
If that isn't the cause.
Are you overweight? That can lead to stress incontinence. If so try losing weight.
Kegel exercises will help strengthen the muscles that hold your pee.

Well you could go see a urologist and discuss your options. It sound's like your urethra or bladder is weak. There are things they can do to help stop this but don't be suprised if they want to wait until your older and finished growing first. In the mean time you could try wearing a panti-liner if it's just a little, I mean a real little amount you pee if not wear a thin maxi pad to protect your clothes a nd prevent you from having a wet spot and smelling like urine. Good luck.
