My 15 year old son was 'diagnosed' as having IBS because of burning in the stomach, sometime waking him at night and causing him problems in the toilet, this would go on for days. He only had a blood test to rule out Crohnes disease.
Yesterday I took him to someone I went to 17 years ago and she tested him for all levels of vitamins, minerals, hormones, organ function (breaking the stomach down into about 5 parts), and any nasty bugs that may be lurking around. She also tested him for food allergies. We got the results straight away and now I feel I have a basis to work from. I know exactly what he can and cant eat and exactly what is going on in his body. Money well spent in my opinion.
She is not insisting we come back and see her as it was 2 1/2hours drive from where I live, but is available at the end of the phone if I want to speak to her and the option is open to go back if I want.
Much better option for a youngster (or anyone) than a camera either up or down, so glad I went down this route as I feel this could be the answer to his problems.
Things are looking up.
