Hi, I'm Marsha and I've had my permanen t ileostomy for almost 60 years, and althought I considered it " high output", it wasn't liquid, and I rarely had a problem with dehydration... I ate pretty much everything I wanted, remembered to chew well, and drink a lot of fluids especially during the summer...All was well until about 3 years ago, when I started to have bouts of " the runs", with the output being almost clear liquid, and often had cramps a nd pains with it. It could last for a few hours, and sometimes a few days.. I finally went to a gastro dr.. ( hadn't needed one for 55 years) and he diagnosed it as a type of IBS...... People who have a colon ( large intestine) are prone to having it......but for us, ( those w ithout a large intestine) have more difficulty.... since we may not be producin g all the enzymes needed to digest the food we're eating... He had my try the FODMAP Diet ( google it)... It's somewhat complicated, and you need to eliminate many regular foods and restart with b asics ( protein, bread, carb, etc) basically fodmaps are hard to digest sugars and carbs/ that are found in many common foods...... fruit, tomatoes, lemon, lime, sugars / even artificial sugars... When you reduce your diet to some basic foods ( no carbinated drinks or artificial flavored drink) and you see an d improv ement in y our output, give it some time.....a few weeks...? and then add just one food at a time back ... Each time you add something new.....consider it a test.. just because you have n o reaction one day, doesn't mean you may not have a reactionn another time.. I'm doing it for about a year now..... and have had v ery good results... I may get the " runs" for a few hours, every so often......but not for days at a time.. And like you, I've had to be hospitalized to get fluids until the runs stopped... I actually am having an " attack" now", as I'm writing to y ou......but it's the first one in about 10 months.. I can strill drink water.....so no need to go to the hospital....yet... If I can't hold fluids down.......then I go to the hospital... This is all new to me, and I keep hoping it will dissapear, but obviously, it's still an active condition. I d on't even know what it is that I ate today, that caused the problem..... Tomorrow will be oatmeal, eggs, and toast.! Best of luck to y ou. Write if y ou wan t or need more info... Look into t he Fodmap diet, and it's explanation..... it's really helped me manage the condition.... Marsha
