Shamrock, thank you for sharing your knowledge! I use one piece bag of Coloplast and haven't had any problems.
Of course, comfort and ease are very important factors for choosing a company that produces ostomy bags. But also, price is a critical issue, at least for me (Japanese) who may be given a subsidy.
As for asking a nurse, I've thought it is a good idea, but I realize that she is not an estimator. Therefore, she has never had feelings about how comfortable or not, for example. I guess it is best to ask the members of this site, and trying different bags is the second best.
In Tokyo, there is one organization for ostomy, but the number of members is getting less and less, and also the average age is quite high. They organize one gathering for everyone, and another is for those under 40. I don't know how often the young group holds gatherings. It's sad that the gathering for everyone is not held often, probably because the organizers are quite old...
Actually, at the one face-to-face gathering I attended last week, there were only six people, and the average age is nearly 80... However, they were all experts about ostomy, so their advice based on their long experience was extremely helpful!!
Well, I'll stop now. I will post questions on the forum when I have them.
