I don’t know if this is helpful at all, but my GI doctor says I have colonic dysmotility in addition to gastroparesis. My main symptoms of lower GI dysmotility are pretty significant constipation, bloating, and abdominal pain. I was taking Miralax twice every day, but it really didn’t have any effect in symptom management. I have just started taking Linzess, so hopefully that will help. Good luck!!

I am similar - I have hEDS, Gastroparesis, SMA Syndrome, Colonic Inertia/dysmotility, intestinal dysmotility, and tethered spinal cord. Basically everything from my mouth down is paralyzed. My GI suspects it’s inflammation from hEDS, denervation of the spinal cord nerves to the colon, and SMA syndrome, and who knows what else.
