My daughter was diagnosed with gastroparesis 12/14. A naturopath further diagnosed her with parasites. She's been on the GAPS Intro diet and supplements. GAPS is a very limited diet that heals the gut. Check out their website if interested. The key supplements are a probiotic, digestive enzymes, activated charcoal, ginger, turmeric, and garlic. My daughter was also tested for food sensitivities. She receives acupuncture and chiropractic care. Massage, Reiki, and counseling have also been helpful. She has improved a lot; the extreme weight loss has stopped and no vomiting. The bloating is still there and she has constant pain, however. The GAPS diet can take up to two years to be fully effective. Patience is needed! Our naturopath helped immensely. There are also GAPS practitioners who can support this route. My daughter is carrying on with her life, at a slower pace than before. She has a positive outlook and we know that she will kick this eventually.
