Hi I've read Apple cider vinegar is good for digestion. I am hypo and want to try it. Anyone on here try it and how do you use it? On 50 McFadden synthroid feel pretty good as meds just raised a month ago and improved symptom. Only thing bothering me is stomach issues. Gas bloating constipation pain. Every morning wake up nauseous with high stomach pain right in middle also in lower abdomen. Just had endoscopy colonoscopy. Endoscopy fine had polyps removed have diverticulosis. Iron ok b 12 and d vitamins ok. Tested for h pylori negative. At whirs end what else to do. Been gluten free for 3 months. No difference but sticking with it. Anyone have any ideas what I can do? Thanks for help.
