Incontinence is not a disease, but a symptom. It is defined as a condition, where a person experiences involuntary urination or bowel movements to an extent that affects the person's social life in a negative way.
Urinary incontinence means losing control of the bladder. In some cases it results in a total loss of the bladder’s contents and in other cases, it merely causes a small leakage.
There are many causes of urinary incontinence such as physical damage, ageing, cancer and infections. Some conditions are temporary, while others are more permanent.
The above are only examples. Always seek diagnosis and treatment advice from your General Practitioner if you experience incontinence.
