Has anyone else experienced heat intolerance or palpitations and tachychardia despite being hypo or euthyroid?

I finally got in to see my new endocrinologist this week. My last appointment with an endo was in January in Florida, and after never going more than six weeks between appointments, this was a long wait for me.

Alas, I am hypo. Not terribly. My TSH is 15. I knew it. I feel tired and sluggish and have not lost an ounce despite overhauling my diet and exercise regimen.

He felt no thyroid tissue (thank you, RAI). He made me drink about a dozen sips of water. I’ve never done that before and I saw my last endo for two years, every six weeks so I guess that allows him to check for thyroid tissue…? He said the heat intolerance and the fact that I still can’t go a day without a beta blocker, and sometimes even need a second one, is almost certainly NOT related to my thyroid because no palpable tissue remains and my labs clearly indicate hypothyroidism.

I’m to up my Synthroid. I was alternating 50/75 mcg every other day, now he wants me on 75 mcg every day. He also suggests I see my PCP and possibly a cardiologist. I had a full cardiac workup in February 2010 when diagnosed and again in April 2011 when diagnosed with GERD and a thyroid nodule. Both times, all the tests (including enzymes, echos, stress tests, etc.) came back normal. I have never felt relief from the heat intolerance or the racing heart. And if I have more than a half glass of wine, I need a beta blocker or else I feel like my heart will beat out of my chest.

Am I the only wacko who’s hypo yet feels hot with a racing heart all the time? It is not anxiety or depression – I am the most calm, peaceful and content I have been in years.

Hi gatorgirly – Hopefully, you will get some other responses from others who have experienced hypO. I do know that I’ve heard from a couple of patients who still had heat intolerance, even after being treated with RAI or surgery, but I haven’t heard a good medical explanation for that.

Take care!

Hello Gatorgirly when did your RAI treatment/how long did it take for you to go hypo?

I had RAI in February 2011 and it took exactly six months to go hypo. I was only hypo for about 3 weeks.

I’m currently experiencing a mix of hypo and hyper symptoms. Was diagnosed about 2 years ago with Graves, T3 and T4 slowly going down into normal range, but not steady, labs bouncing around. TSH finally starting going up with Dec 2011 labs, and was 2.9 in March (very old labs suggest that my normal might be around 0.80). I’ve been oscillating between hypo symptoms (migraines, constipation, freezing cold) and hyper (waking up sweating, dry eyes) every few days.

So we changed from dosing twice per day (7.5 mg methimazole split into 2 doses) to 5 mg in the evening only.

Now I’m sleeping great, but waking up with a migraine, or the feeling that one is going to arrive soon. But I still have some hot flashes and the dry eyes.

It sure seems to me like there is a hypo/hyper war going on inside of me! If it continues much longer I may talk to my endo about taking 3/4 tablet at night and 1/4 in the morning.
