Have you looked at food allergies or intolerances? My daughter was diagnoised with IBS-C along with migraines and dizziness. We took her off of milk and every symtom went away. If every test is negative, take a look at what you are eating. You might take a look at "Breaking the Vicious Cycle" book by Elaine Gottschall. It focuses on intestinal health through diet. I also suggest a fecal analysis for food intolerance then meet with a dietician who specialized in IBS.View Thread
My 10 year old daughter was diagnosed with IBS-c. She also suffered through intestinal bloating and pain, constant headaches, migraines and dizziness . She was put on meds that didn't see to work. she was slightly positive for SIBO, but had an allergic reaction to the antibiotics.
After much prayer and careful observation, it was discovered she had a milk intolerance. After three days of being completely off of milk the migraines, headaches and dizziness completely went away. Her stomach size decrease 2 inches and she lost about 5 pounds.
We did a MRT test for other food intolerances. She is now working with a dietician and is slowly reintroducing foods. She is off of all medications.
I wish I went this direction first rather than spending thousands at the specialist.View Thread
