<<Disclaimer: Verify this information before applying it to your situation.>> Greetings, list: Does anyone have both celiac and Hashimoto's? I have just been diagnosed with the latter and began taking a low dose of synthroid a few days ago. I am particularly curious about what anyone with both conditions might have to say about weight gain or bloating. I have been gluten free for about a yea--few problems before the celiac diagnosis, but a marked improvement in my complexion since (no longer anemic.) I had no problems with weight gain or with bloating until now. I suppose a little hypothyroidism can account for weight gain, but the bloating, especially at night and irrespective of the day's diet puzzles me. And how long after you began taking synthroid did you notice changes? What were they? Please reply to me privately. I shall post a summary if it seems warranted. Thanks - Mary Brown
