Hi Chris,
Welcome to the site. Since you have the time to plan, it's great that you're asking all the questions now. I'm Marsha. I had my ileostomy for ulcerative colitis, more than 50 years ago, when I was a kid of 15. I'm 68 now, and I have to say that despite the "ancient supplies" available 50 years ago, I've been able to do just about anything I wanted to do. I spent summers at the beach and at pools swimming, did the wild rides at water parks with my kids, I biked and hiked, and camped... had my two miracle children, and have travelled extensively these last 20+ years. Some of it was driving, some was flying in a single-engine plane, with no bathrooms, lots of cruising and lots of touring. Only fiasco was my appliance popped off while I was swimming in the Dead Sea in Israel. Messy but fixable. No fiasco snorkeling on the Great Barrier Reef... or when riding an elephant in Africa, or on a helicopter in Alaska! The best thing you can do/ask is consult with your doctor about stoma placement. Not too high... so it doesn't show when you wear a bathing suit... Sometimes, they have to place it where they can. If they're removing the rest of your colon, you'll end up with an ileostomy... meaning the stoma will be at the end of the ileum or small intestine. That will make for a more liquid output. But that can change over time. The colon/large intestine absorbs most of the fluids in our waste, so you need to remember to drink enough water, especially during the summer. The best suggestion is to eat easily digested foods at the beginning, like bread, pasta, rice, meat, etc., and add vegetables a little at a time, to see what works for you. Foods with more fiber (corn) will cause more bulk to the output. Many can eat raw veggies, some can't. I can eat some things like lettuce and tomatoes, but not raw carrots or cabbage. Dairy products can be an issue for some people if it triggers digestive issues. I gave up dairy products a few years ago and feel much better. But I do cheat on occasion for some good ice cream. I prefer a two-piece appliance and currently use Convatec... You can write to each of the companies and ask for suggestions. Trying a pouch on is okay... but most of the time, output is thicker than water. Don't try to fill the pouch completely, or you will "slosh". And yes... you can wear tight jeans, as flat as you're comfortable. As I've gotten older, I seem to have more air/gas... and that fills up the pouch faster than waste. If you have any other questions or concerns, just ask us here. Best of luck to you. Marsha
