Overactive Bladder Syndrome Understanding
How the Bladder Functions:The kidneys make urine all the time. A trickle of
urine passes constantly to the bladder down the ureter (the tubes from the
kidneys to the bladder). You make different amounts of urine depending on
how much you drink, eat and sweat. The bladder is like a balloon with its
walls made of muscle. It expands as it fills with urine. The outlet for urine, the
urethra is normally kept closed. This is helped by muscles beneath the
bladder (pelvic floor muscles) that sweep around the urethra that acts like a
valve.
When the bladder is nearly full with urine, you become aware of the bladder
getting full. When you then want to pass urine, you allow the bladder muscles
to contract (squeexe) and the valve at the urethra, ie the pelvic floor muscles
to relax thus allowing the urine to flow out. Complex nerve messages are sent
between the brain, the bladder and the pelvic floor muscles. These tell you how full your bladder is and tell the right muscles to
contract or relax at the right time.
What is Overactive Bladder Syndrome:
An Overactive Bladder Syndrome is when the bladder contracts without you having full control over it, particularly when it is not full.
An Overactive Bladder Syndrome is sometimes called an irritable bladder or detrusor instability (Detrusor is the anatomical name for
the bladder muscle)
Symptoms:
•
An urgent feeling to go to the toilet
•
going to the toilet frequently (more than 7 times a day)
•
urge incontinence - leaking urine before you can get to the toilet
•
nocturia - waking up at night to go to the toilet more than once.
What Causes Overactive Bladder Syndrome:
Many physical conditions can cause the problem. OAB affects millions of people all over the world. It is estimated that about 15% of
the population in USA and Europe are affected. In Asia it is more like 50%. The usual causes are:
•
Urinary infection
•
Neurologic disorders
•
Bladder tumours
•
Enlarged Prostate
•
Weak Sphincter
•
Psychochological causes.
If you are feverish with a burning sensation while passing urine, the urine is discoloured, smelly or blood stained or you notice total
incontinence you must seek urgent medical advice. Of the many causes of incontinence the commonest are due to weak sphincters.
As we get old there is a tendency for the pelvic floor muscles to get weaker. This can often lead to weak sphincter causing urge
incontinence or nocturia.
OAB can be diagnosed easily. Once the more serious causes of an irritable bladder is ruled out, it can be treated effectively by
Pelvic Floor Muscle strengthening exercises with or without medication (anti-cholinnergic drugs).
The bladder training programme consists mainly of exercises to strengthen the pelvic floor muscles. Arnold Henry Kegel (1894-1981)
an American Gynaecologist was the first to advocate these exercises for patients suffering from urinary stress incontinence and
genital prolapse in women. The Kegel exercises are now proven to be very effective for both men and women suffering from stress
incontinence.
There is a tendency among patients to drink less fluids to reduce incontinence. This you must never do as water is essential to wash
out all the toxins and waste products that collect in your body. You must drink between 1.5 to 2 litres of water a day to keep the
kidneys healthy.
