As many of us with hypothyroid know, constipation is one of the symptoms of the ailment. I am one of those that has suffered for years with hard, rocky stool. Then I read about how if you are deficient in Thiamine or vitamin B-1 it can cause a "miscommunication" between the thyroid and bowels. I began taking 250 mg of B-1 everyday a couple of weeks ago and no more cement factory poops. It just may be coincidence. But, so far sooooo very good. I am actually not dreading to go do number 2. It's worth a try. I just hope my situation remains, eh hem, smooth sailing.
