This is the only forum I've ever been on and only the 3rd post so I'm not sure if it's done correctly or even necessary but I'd like to try to share my info. The first post was a week after my permanent colostomy and I was asking for advice on not having any sign of output and I received several encouraging replies. Thanks. And yes, output did begin a couple days after. And the other post was about use of mineral oil as a pouch lubricant. And yes, in my case, mineral oil is what I use exclusively, with all pouch changes and as needed after emptying. This is with a Hollister New Image two-piece with a convex barrier.
My first few weeks I was constantly frustrated with thick, pasty output. Especially with the convex barrier, the whole opening over the stoma would be cemented shut with the mess and it was, as I said, frustrating, all day and night fighting with laborious cleaning and unclogging. I spend days researching, reading, and watching videos and experimenting. To shorten the story, I found for me the answer was a high-fiber diet. I know this is not for everyone, (as I've been told on this site), but I found that sticking to whole wheat and whole grain products, and the beans and brown rice, some fruits and vegetables with the peel, I have been able to keep my output the consistency I prefer. For anyone interested, the preferred output for me is the Type 3 on the Bristol Stool Chart.
There are scores of websites that talk about this Chart and the normal stool between type 3 and type 4. But of the hundreds of articles I've read, there are none that say "Here's how you diet to achieve Type 3 output." So you just have to read and experiment to see what works if that's your particular goal. For two months, I kept a detailed spreadsheet of what foods I ate, time of day, and approximate grams of fiber, with the goal of 30 grams per day. It worked for me.
That's a snapshot of my experience, as new as I am to the ostomy world. Hope someone will benefit from the information and will share theirs with me.
If there is anyone interested in more about the spreadsheet data I've kept for February 24 through March 28, 2020, let me know.
Cheers
