My apologies - I just noticed that I duplicated the link for AGMD physicians instead of including the link that I intended.

https://www.ncbi.nlm.nih.gov/pubmed/28154021 Gastric emptying scans are OFTEN performed outside of the standard recommended testing protocol. Changes in the meal served, the amount eaten, the length of the test, or even the positioning of the patient can cause dramatically different (and invalid) results. - In other words, please see a GI who is a Gastric Motility sub specialist if you have a real concern that you have gastroparesis.
