You're not pregnant and you haven't gained weight, but your
jeans are straining at the waist. So what's going on?
Irritable bowel syndrome
Could be the cause if: You've been bloated on and off for a 
long time and have also experienced symptoms including pain, 
constipation and/or bouts of diarrhoea.
A common bowel condition, IBS is a functional disorder, which 
means there's nothing wrong with the structure of the bowel 
itself, but the way the gut works is abnormal.
Peter Whorwell, professor of medicine and gastroenterology at 
the University of Manchester, says, "We think the gut is 
over-sensitive in IBS sufferers so its normal processes cause 
the symptoms." Bloating is one of the most disruptive side 
effects of IBS.
Some women go up a couple of dress sizes and even need 
different clothes depending on whether or not they are 
bloated. For many, it tends to worsen towards the evening, so 
it can disrupt your social life. There's no cure for IBS, but 
you can manage the symptoms.
"Cutting out cereal fibre eases symptoms by between 30 per 
cent and 40 per cent in the majority of sufferers," says 
Professor Whorwell.
This means avoiding whole meal breads, oats, muesli, 
digestive biscuits, cereal bars and all breakfast cereals 
other than Rice Krispies, but white bread, cakes, cream 
crackers and most biscuits are fine. Try doing this for three 
months to see if it helps. Probiotics may also ease symptoms. 
Try yoghurts, as the probiotic strain they contain has been 
shown to help IBS.
