My wife who has hashimotos, has lately had an increase in symptoms including a pulse and blood pressure that varies every time we take it, light headed ness, an almost fainting incident while walking, weakness and fatigue, she had an irregular electrocardiography in her annual physical and her doctor suggested and scheduled an echocardiogram. My wife has severe anxiety upon the thought of going to this appt. so she has put it off for three months. I am concerned that she is ignoring heart problems and the current malady has nothing to do with hashi s. Is it possible that her symptoms are not thyroid related?
