Hi all, I have had my ileostomy for over 55 years, since I was 15, and for most of that time the only problem I had was with raw veggies (celery, cabbage) and some nuts. My output was sometimes watery, but generally speaking it was "normally liquid/muddy range. I always drank a lot (of plain water) and rarely had issues of dehydration. The more I drank, the more I peed, and the guide for that, the paler the better. If it was yellow, I needed more water. All was fine until a few years ago. I started to feel explosions of gas, and even though I switched to a pouch (Convatec) with a vent, I found the gas continued ending up in liquid, and then green liquid, and then almost yellow liquid. In the last 2 years, I've been hospitalized 2x for dehydration, with no real pathology, infection, or cause. I finally went to my gastro doctor (who I had not seen in years), and he diagnosed it immediately. Since I don't have any large intestine, he said I might be missing specific enzymes (?) to digest some foods. My output often had a very foul odor, which I never had in the 50 years of having an ostomy. He recommended reading up and trying to follow the FODMAP Diet. It's based on eliminating the hard-to-digest sugars, carbs/artificial sugars that are found in many vegetables, fruits, and juices (tomatoes, lemon limes, some green veggies, garlic, onions, artificial sweeteners, and carbonated drinks as well). I was devastated and felt like I was back to that teen with ulcerative colitis. Back to a very limited diet. But I did a lot of reading and categorized the specific foods. Once you eliminate the "identified" problem foods, it's okay to try them (one at a time) on occasion, like allergy/taste testing. I love pizza and Italian food, but I react to tomatoes, so I only have a little sauce or a piece of pizza. I can cook with onions and garlic, but it's best if I don't eat much of either. At the time, I was guzzling lemon crystal lite, but it's no longer on my list. Hard cheeses are okay, but soft cheeses may cause problems. I avoid most dairy, but use almond milk. If I have to have milk, I do indulge in ice cream occasionally, just not every day. It's a challenge, and it makes preparing some of my favorite dishes a bit difficult, but I've noticed major changes and more consistent output. My pouch was filling with gas 2-3 times a night, and I had to get up to release it, or I would break the seal on my wafer. That's improved with the diet, and sometimes, I don't even have to empty. So if you're having specific issues related to gas and foods, check out the FODMAP diet. It might work for you. Best of luck to all. Marsha
