Hernia issues wouldn't be connected to thyroid. BUT the bowel issues FOR SURE are. That is how we figured out our son had thyroid disease, his GI was trying to sort out his bowel issues. Hypothyroidism slows everything down - at one point he hadn't gone to the bathroom for SIXTEEN days and his body was going toxic. Being on a stable level TOTALLY sorted that out. For mental health things - you may find that once she is stable with her meds those all go away BUT if they don't please don't stop looking for answers. That is what lead us to the pdd-nos diagnosis. Our son was stable for too long for mental health issues to have anything to do with his thyroid. I asked his endo and she told us to keep searching for an answer to solve what was causing them because once a person is stable with their meds there is no symptoms. If you are having symptoms you aren't stable yet or they aren't from your thyroid.
