I have gastroparesis but mild form, Dr put me on donperidone,and that really helps I was scared to eat when I first got diagnosed, 3 months ago, but now I try different foods, and see how it goes, and most of the time I feel fine, I got something, that helps with nausea, but I have used maybe 3 pills, so diet is key if there's a food that caused trigger don't eat it anymore. Feeding tube is for very severe cases is what my Dr said.
