IRRITABLE BOWEL SYNDROME
Irritable bowel syndrome involves a group of
symptoms such as pain, excess gas, diarrhoea
and constipation.
Many people with IBS experience alternating

(bowel) become extra sensitive and the
intestine does not work properly.…read more

HOW DO THEY DIAGNOSE IT?
There is no test that confirms the diagnosis of IBS. A
doctor can usually diagnose IBS from the typical
symptoms.
However, a blood sample is commonly taken to do
some tests to help rule out other conditions such as
ulcers, colitis, coeliac disease, gut infections, etc.
The symptoms of these other diseases can sometimes
be confused with IBS. Tests done on the sample of
blood commonly include:
Full blood count (FBC) - to rule out anaemia which is
associated with various gut disorders.
Antibody testing for coeliac disease.
More complicated tests such as endoscopy (a look
into the bowel with a special telescope) when other
conditions need to be ruled out.…read more

WHAT CAUSES IRRITABLE BOWEL
SYNDROME?
The cause is not clear.
It may have something to do with overactivity of part
or parts of the gut.
The gut is a long muscular tube that goes from the
mouth to the anus.
The small and large bowel (also called the small and
large intestine) are parts of the gut inside the
abdomen.
Food is passed along by regular contractions
(squeezes) of the muscles in the wall of the gut.
Pain and other symptoms may develop if the
contractions become abnormal or overactive. The
area of overactivity in the gut may determine
whether constipation or diarrhoea develops.…read more

Here's a taster:

THE CAUSE OF OVERACTIVITY IN PARTS OF THE
GUT IS NOT CLEAR. ONE OR MORE OF THE
FOLLOWING MAY PLAY A PART:
Overactivity of the nerves or muscles of the
gut.
It is not known why this may occur.
It may have something to do with
overactivity of messages sent from the brain
to the gut.
Stress or emotional upset may play a role.
About half of people with IBS can relate the
start of symptoms to a stressful event in
their life. Symptoms tend to become worse
during times of stress or anxiety.…read more

Good power point - covers a couple of diseases in a lot of detail.  The layout includes a lot of information but worth using as a starting point.
