Try Ayurveda, naturopathy, traditional Chinese medicine, or functional medicine. You can find an MD who practices functional medicine on IFM.org I had some problems like this, and these things really helped me out. Also I can definitely tell you that nutrition will help, but you have to be willing to make the necessary life style changes.
Father, we pray for Betty to be healed from low iron and low energy. AMEN!
