Subacute thyroiditis: It sounds like you have gone from being mildly hypothyroid to hyperthyroid. This can happen when there is superimposed inflammation of the thyroid (subacute thyroiditis). This can be seen in autoimmune thyroiditis. In your age group it is most likely either graves disease or "hashitoxicosis". You should see an endocrinologist to help figure it out. ...Read more

A : A low heart rate is called "bradycardia" and is considered to be any heart rate less than 60 beats per minute. Bradycardia can either be a sign of a healthy, fit heart, or it can be a sign of a problem with the heart's electrical system. Marathon runners and other very fit, young athletes will often have very low heart rates - even in the 40-50 beats per minute range. If she does not fit into the "fit, young athlete" category, then there are other things to consider such as damage to the heart from coronary artery disease, heart attack, a metabolic problem such as hypothyroidism, or a medication which can cause a slowed heart rate as a side effect. Since she appears to be symptomatic with that unresponsiveness spell, you or she should discuss concerns with her doctor as soon as possible. They may want to check an ekg and a few blood tests to rule out problems with her heart. It may also be worthwhile to seek the advice of a cardiologist (heart specialist) if her doctor is not sure what to do. Good luck! ...Read more
