Hi, I know that this is a late response to your original post. Are you still taking iodine? Have your digestive issues resolved?
I have a similar story, and am currently going through constipation related to taking Iodoral. This has been tough for me because in addition to my hypothyroid symptoms, I have gone through years of terrible digestion.
Finally, I opted for a drastic measure - FMT - in the Bahamas with Taymount clinic. The results were fantastic. I could feel my microbiome fully restored and digestion came naturally and easy regardless of my diet which is healthy anyways.
Two weeks after starting on iodoral to help boost my thyroid, I started to get backed up. I have some advices, but also maybe need some advices. I wonder if anyone resolved constipation related issues by switching to Lugols? It seems logical that Iodine drops would absorb more quickly into the system as opposed to pills that might travel all the way to the colon.
