Helllo, I am a 32 year old female, I am 5 7 and I weigh 180lbs. I have been diagnosed with Hashimoto thyroidism and currently takes synthroid daily, b-12 nasally every other week, and vitamin d every three weeks. Around the thanksgiving holidays, I had a stomach virus, but got better. However, it seems as if my bile continues to be a little loose and at times my legs feel weak.
