I was diagnosed with gastroparesis a few years ago, I haven’t tried erythromycin (mainly because no one has suggested it) but I have heard of others with non diabetes related gut issues using it and it’s been positive, overall. It’s kinda like a reset I believe? I’m intrigued you’ve not had the delayed gastric emptying test, have you had a blood test for coeliacs? We went through lots of things before we got to gastroparesis, IBS was one.
I was taking metoclopramide and ondansetron but have now stopped these as I started another medication (for something else) and was advised to.
What I’ve really found that worked is looking at my diet. My diabetes team said about the 6 small meals, but I’ve never felt that’s worked for me. My gastro said to try dairy free, gluten free and/or low FODMAP, which I’ve done at varying degrees the last few years. It’s so hard as it’s the opposite thing for each condition. Low FODMAP really helped reset me and get everything moving and comfortable again, and I’ve slowly introduced things again. Alcohol is also on the “bad” list.
I’ve also found intermittent fasting is helpful, I often feel too full to eat 3 meals a day. I am borderline underweight so I do worry about calories, but at least what I’m eating isn’t being vomited back up, so I count that as a win! I’m looking into a low carb diet for diabetes as I want to improve my Hba1, this will be kinda be gluten free as a side effect.
Ive felt really alone with all of this, there doesn’t seem to be a cohesive approach. I’ve been told it’s not progressive for example.
