Hypothyroid and weight gain

[Josie32]

I was born with out a thyroid and diagnosed with Hypothyroidism. I was wondering if it common to gain an excessive amount of weight while exercising regularly and eating healthy. I am currently training for a marathon and running about 9 miles a day or more and I eat rather well. I can't seem to shed any pounds but actually have gained about 10-15 pounds in the last month. I haven't weighed this much since I gained the freshman 15 two years ago. I was back down to 148 over the summer but all of a sudden I am at 164. Is this common????

Make sure your docs treat the FT3 levels as well. You may need some Cytomel added to your Synthroid. Most of us don't lose the weight until both our FT4 and FT3 levels are in the upper 1/3 of the range.

I just finally got tested yesterday, I should get the results by monday and I'll let you know.
I started training about 3 weeks ago but the weight gain started more about 2 months ago, and I was working out regularly and eating really well. I am currently on 137 MCG. synthroid.

Thanks for the response, i hope that helps a little. I will let you know the results when I get them.

My guess is that your meds are not properly adjusted.

When was the last time your FT3, FT4 and TSH were tested?  What were the results and their reference ranges?  Did the weight gain start when you first started training or had you already been training for a while before it started?  What dose and which meds are you on?

Sorry for all the questions...but need to know to answer properly.
