Shortness of breath and hypothyroidism

[jcpomona]

Just wondering if anyone had info on this topic. If been having mild shortness of breath on and off recently. This symptom came on about 4months now since RAI and about two months after beginning thyroid replacement (Synthroid). I notified my endo about this and my levels were checked and my dosage was upped, but a several days later I'm still being bothered by it. I read in a couple different sources that this might be a symptom of hypothyroidism, but haven't found any detailed info as to how or why...  Any advice or info would be greatly appreciated.


Thank you

Hypothyroidism can cause shortness of breath. If your dosage was just raised and your still hypo,  two days would not be suffcient time yet to reverse that. I know that when I was feeling short of breath it was a direct effect of being hypo. Basically I was exausted which led  me to expend more energy, which led to feeling like I just ran a marathon, which leads to shortness of breath. Do you have anny recent labs? Also many other things can cause shortness of breath so don't rule those out as well.
