I fortunately have NOT had to take my kiddos to the GI doctor, but I have gone. I did have bloodwork done, an upper and lower scope done, two rounds of antibiotics, and still not relief. I ended up going to Dr. Shepherd (chiro and nutritionist) to do a food intolerance test by IMMUNO LABORATORIES. WOW, the results were right on. I removed the foods and my issues disappeared.
My lil' one also had reflux as a baby and continued as she got older to have other issues, like reactive airway issues. I took her to Dr. Chalmers in Frisco. He helped her with natural supplements and she if great. We put her on supplements directly for her gut. The dosage is specific to what the child's body is calling for, so it is individualized. Apparently she just has a crazy gut that manifest into different issues as she grows. I feel confident we are addressing the issue at the core with this office. He will also do free consults.
Be careful when doing food intolerance testing......not all labs are equal. IMMUNO has a less than one percent variance........don't assume labcorp or quest or whatever other ones out there have consistent results, they don't. Immuno has a guarantee that it will correct digestive issues or they refund you the money you spent. That is why I went with them. They are not cheap, but I have used them for my daughters' ear infections, and they have not had an ear infection since we did their testing. Just can't say enough about the accuracy and results of this test.
Hope you find help....it is tough to have our lil' ones having issues.
ADDED: IMMUNO is a straight blood draw....not lots of needles, just one. Go to a clinic that has a pediatric staff member to do the draw.....makes a world of difference.
