I have had my thyroid tested and the results were normal, however, I am concerned because for the past few years I have experienced extreme weight fluctuations...I can go up nearly 30-40 pounds in about 2 months with no significant change to diet. My hair falls out, my eyebrows are thinning, Im very fatigued, and my skin is sensitive and prone to severe stretchmarks. Could the test have been wrong? What else could be causing this...my life has been drastically affected by my lack of energy and mood.
