Going for RAI tx next week... Diet?
I've had hyperthyroidism with Graves' disease (and slightly, slightly swollen eyes) since I was 16 (I'm 22 now) and it has been well controlled on Methimazole, up until recently (I switched from 20mg/day to 10mg/day). I've finally decided to get RAI done, and it is scheduled for 1/18/13. I start the low-iodine diet on 1/11/13 and I stop taking Methimazole on 1/14/13. Just to be clear, I do plan on reviewing everything I'm about to ask with my doctor prior to or during treatment, but I wanted to hear from others that have gone through this as well.
First, the weight gain. I, like probably many others, am terrified of gaining weight. I'm normally a very healthy and active person, but I've since been relatively inactive because I've had major ankle surgery in late November. I'm just getting back into swimming and cycling, plus I'm looking into getting a rowing machine for some more low-impact, higher-intensity workouts. Obviously, I'll need to take at least a few days off from these activities post-RAI (well, the swimming, at least), but I do have a stationary bike at my house that I'll be able to use. As long as I work on portion control and I continue to exercise, will I gain a ton of weight or should I be okay? The weight issue is also big for me because I do have congenital heart disease (I have a repaired mitral valve -- done exactly 16 years ago today). My checkups are always great, but of course I know that excess weight can have detrimental effects on my heart. Diabetes also runs in my family, which is why I want to continue to stay thin.
I'm a very healthy eater. I'm big on fruits and veggies, organic chicken, and salmon. I also like whole wheat pasta or organic brown rice with some of my meals. Will I still be able to eat all of these things? I know I'll have to avoid things like salmon, etc. during my low-iodine diet, but how long should I stay on the low-iodine diet and when can I return to eating seafood? I've read that I will have to avoid things like spinach, cruciferous veggies like broccoli (which breaks my heart), and even fruits like strawberries and peaches. Is this true? I know I can't believe everything I read on the internet, so obviously I plan on asking my doctor about that, but of course I don't want to jeopardize my thyroid health. Finally, I drink very little dairy, but I do have ankle instability due to very, very low grade arthritis. Obviously, I want to have some calcium in my diet in order to keep up with the strong bones. Should I drink more milk (non-fat), or would something like a calcium supplement be better?
Can anyone else bring in some of their experiences with RAI in terms of weight gain, nutrition, etc.? I know I won't be put on Synthroid for at least a few weeks (and I do plan on getting very regular checkups via bloodwork, etc.), so I just want some coping strategies and advice on how to deal with this. I tend to have a lot of anxiety when it comes to medical procedures thanks to my past medical experiences, and I keep canceling the RAI and I don't want to do this now.
Thanks for all the help!!
