I have my thyroid tested once per year because my mom had issues with hers. I started having heart issues in late January and my gp ran a thyroid panel to check the levels in February. It came back normal. Now here we are in October and I am having heart issues again. Losing weight is a battle, my hair is now falling out, I have NO energy and constant headaches. My cardio has ruled out my heart by doing a cath. So now I am wondering, if it could in fact be my thyroid. Can it go bad in 7 months?View Thread
