Gastroparesis - Hi, my husband was diagnosed with GP starting the beginning of this year. His?

He is probably dehydrated too. Need to be sure he drinks gatorade or something to keep his electrolytes in balance, especially when he is vomiting. Best to keep him hydrated at all times. These episodes sound like flares. See if his dr. will prescribe him zophran or phenegren or something for the nausea. Ginger is also good. Maybe you can catch it before the vomiting starts. I have gastroparesis, and right now I'm living on Ensure milkshakes and protein powder, pudding, juices and almond milk. Can't eat anything solid without causing pain in my stomach and nausea.Stay away from most fat and eat small meals. No red meat very very little fiber--stays in stomach too long and causes symptoms. He may want to stay on liquids a couple of days then move to Ensure a couple of days then move to soft foods.That's what I have done, and it has worked out well. Hope this helps
