I have gastroparesis as a result of damage to the vagus nerve during hiatal hernia repair surgery (Nissen Fundoplication). The wrap has slipped and I have another hiatal hernia and Barretts esophagus. I follow a very low fiber diet, no raw fruit or vegetables and I avoid some cooked vegetables that tend to be fibrous. The drug Zolfran helps when the pain just doesn’t go away. I don’t vomit because I can’t vomit. Sometimes it feels as though food just stays in my stomach and rots! Living with gastroparesis is a challenge! The International Foundation for Gastrointestinal Disorders has a lot of helpful information. Check their website, IFFGD.
