I take medication for an under active thyroid. I walk 10 miles and swim 1mile daily. My diet consist mainly of salmon and greens. I purchased some fresh seaweed from Wholefoods. I started eating the seaweed on a Sunday evening, Monday morning, Tuesday morning. on Monday and Tuesday I felt like I had symptoms of low blood pressure, hyperglycemia. My blood pressure tends to be on the low end. Could the symptoms be a result of eating seaweed because of its high content of Iodine?
