I have high thyroid and I am only 19 right now. I get excessive gas. And transient due to it. Doctor's on Lybrate are telling, thyroid could be the cause, but I personally feel it only happens when I have excessive gas. Whatever is the reason, my tsh is not normal. I am taking medicines, but I want to know if there is a problem in heart, or could heart flutters damage heart? If yes, do these flutters need separate treatment. I surely think my heart is alright because I have no problems, even when climbing a mountain faster than others.
