JL I forgot to comment about the thyroid - potential Hashimotos Syndrome. Having been battling with low iron for probably a year now and not even knowing why I was so exhausted all the time (thinking it was just age and life frustrations not health) it can take it's toll on a person. This will give her some relief and encouragement if she finds out exactly what is going on and has a treatment plan. When will you know for sure and she can start getting treatment?
