No Exercise?

Hi.  About 2 years ago and six months postpartum with my youngest child, I started having a resting heart rate of 120 and easily went to 180 just standing in line at Wal-mart.  I was also dizzy, and I felt like a windup toy that couldn't shut off but felt exhausted nonetheless.  I also lost about a pound a day--the one good thing!  

The doctor said it was probably thyroid, ordered blood tests, and my TSH was 0.001, my free T3 was 4.7 and my free T4 was 7.  I also went to an endo who ran antibody tests which were sadly inconclusive.  Shortly after that, though, the symptoms all disappeared.  I had stopped drinking Diet Coke and coffee and had started taking copper, magnesium, calcium, and selenium per ithyroid.com.  It's hard to say which if any element caused the end of the problem at the time.  Now, however, my heart rate is back up (though not as high at all), I'm gaining weight, and feeling very relaxed.  My GP ran more tests that I fully expected would show that I was in a state of hypothyroid instead of hyperthyroid.  I was wrong.  My TSH is now 0.019, Free T4 is 2.51, Free T3 is 7.4, TSI is 175, TPO is 518, and antithyroglobulin Ab is 410.  The endo I went to yesterday said I definitely have Graves' disease.  She prescribed PTU and propalynol.  I am happy to finally have some treatment and hope they'll work as the thought of radioactive iodine ablation is quite fearsome to me.

Here's my question.  She also said that my heart has been under so much strain that I need to rest.  I am not to exercise, I am not even to take a walk, and I should avoid anything that raises my heart rate above 100.  That's pretty much everything, so my poor husband is doing a lot more housework than usual after he gets home from work.  Has anyone every heard of being told to rest so very much?  This should just be for 4-6 weeks until the PTU kicks in, but I wonder if the doctor is being overcautious.  Thanks for the help.

Those with hyperthyroid condition are in danger of damaging their heart by over exertion.  It is best to trust your doctor so you can recover.  When they feel your heart rate is stable, they will allow you to start mild exercise.

Yes--you need to rest.  Find out if a beta blocker will help you.  I was hyperthyroid and I had to take it easy--it is better for your heart.
