Mom visited another internal medicine doctor today. It turned out she knew more about intestinal motility problems than he did and he basically told her he couldn't help her.
Mom's gotten a little relief in the past couple of days from Erdman therapy, which Dad is able to do for her, thanks to a nurse friend who explained how.
She also is trying to include more protein in the small amount of food she's able to eat, as she read on one web site that protein deficiency can cause ileocecal valve syndrome. She had been eating mainly grains and veggies lately as they tend to be easier to digest.
We'll see what happens. May have to investigate other medical options. I'll keep you posted. Thanks for your prayers and concern.
