I was diagnosed with Gastroparesis about 3 months ago. The symptoms I had were slight vomiting, stomach pain and a lot of bloating. I had a gastric emptying study which showed very slow emptying of the contents. The diagnosis was based on the study and the results of an endoscopy. The endoscopy showed undigested food from 4 days prior. I went for a follow up endoscopy 4 weeks later (after following a low-fiber Gastroparesis diet). The doc found that the pyloric sphincter was narrowed quite a bit. This too would cause delayed emptying. He used a baloon to stretch it open. Since then, my only symptoms have been slight bloating and constipation. I am on ocycodone for severe cronic back pain (which of course would cause the constipation), but I’m also not getting much fiber either because of pmy diet.
My whole point of this is that I don’t know if I truly have Gastroparesis or if my issues were caused by a small pyloric sphincter. I have another follow up with the GI doc in a couple of weeks. Hopefully he will be able to determine the cause of my problem.
I’m not suggesting that your situation is the same as mine. I just wanted to share in hopes that it may be of some help to you.
