I have combined the Institute of Functional Medicine elimination diet with the Monash Low Fodmap diet, plus only low histamine producing foods since May 10th. It is now June 16th. I will continue for 3 more weeks before reintroducing food one at a time. I am experimenting on myself. Two years ago, I became a Functional Medicine Coach. I wanted to apply this medical approach and knowledge to see if it worked for me. If it will, I will have my own personal experience to share. 2 years ago, my BMI was in the morbidly obese category, Now I'm in the obese category and hopefully this year, I will be in the overweight category. I had a colonoscopy and endoscopy this week and found out I have a redundant/tortuous colon. I was in the hospital, under anesthesia for the procedure. My gastritis symptoms have gone down to mild (no medication nec,) and I'm waiting for biopsies of both ends. After 4 weeks on these combined diets, I still experience extreme constipation with no urge. I'm only in the beginning phase of elimination. The only supplements I'm takinh are D3 50,000 IU 1x wk (until my D level is around 60) and Digest Tone (Triphala and Rose, an Ayurvedic px). I get a Xolair injection (a monoclonal antibody that inhibits IgE production) eve. 2 mos. for an autoimmune condition. Nothing has been successful for the constipation. I welcome all comments and ideas.
