If u over eat one time is that going to do any damage besides hurt lol cuz I accidently just did now my left side hurts rly bad and I'm scared what if it stretches the stoma out

You'll be fine. Our bodies aren't that fragile...one mistake isn't gonna ruin everything. Next time, be more proactive. How can you not overeat? Portion out your meals ahead of time. This way when it's gone, it's gone and there's nothing more to eat. I stick to about a cup a meal, some do more, some less.

Hope your pain goes away soon
