I was diagnosed with this about 15 yrs ago - cause was my pancreas not working properly. I was given special enzymes to take with every meal to stop the symptoms of agonising stomach cramps and diarrhoea. I was told that it was usually seen in patients who had been alcoholics for 40yrs or more (I was in my very early twenties and hardly drank back then!) and told that I would be diabetic within 10 yrs as my pancreas would gradually fail and eventually stop working completely, but not to worry as pancreatic transplants might be available by then!
After 3 or 4 yrs I stopped taking the tablets as I was pregnant and have had no more symptoms, have not become diabetic etc.
If this is what you have been told you have (and who told you?) then it's uncomfortable and unpleasant to have but it's not embarassing to discuss with your GP, is easily controllable and may go away on it's own - but you do need to have the underlying causes identified. Good luck
