Could you tell me what are kegel exercises?

Bladder exercises: Kegel exercises are designed to build up the urethral sphincter muscle which is at the opening of the tube that empties the bladder. These exercises will decrease leakage that is caused by laughing, coughing or sneezing. Women learn to isolate the muscle by stopping a stream while urinating. They should then tighten and hold the muscle for a count of 10, up to 20 times daily.

Other types of incontinence won't get better with these exercises and may need medication or even surgery.

Bladder exercises: Pelvic floor exercises help to improve the tone and strength of the pelvic floor muscles, thus helping with pelvic organ support. This will decrease risk of pelvic relaxation, uterine descent, bladder descent, urinary incontinence, and helps to promote healing and comfort after pelvic surgery or childbirth. To get the feeling for these exercises, try stopping the flow of urine while voiding and try to tighten your bottom as if you’re trying to hold back gas.
