Hi, I'm aware that hypothyroidism can cause your GFR to decrease; mine has dropped to below 90, say around 84, from being 90. I know it's not too much to worry about at the minute, but with my mother developing renal failure at the young age of 15, it is on my mind. My tsh went to 8.4, so I've increased my levo..but can short term raised tsh cause a drop in gfr? Tsh was well in range in Jan...
Cholesterol is very good, hbA1c is good.
Thanks. 
How much Levothyroxine are you currently taking?
Do you always get the same brand of Levothyroxine at each prescription?
Bloods should be retested 6-8 weeks after latest dose increase
Make sure to get FULL Thyroid and vitamin testing. Privately if necessary
How's the gluten free diet going?
Hey, so as of yesterday I am on 100. Gluten free is, well I'm 90% gluten free, but sometimes I fail. I'm avoiding soy too.
I take various vitamins, but avoid taking them for like a week prior to testing as they contain biotin.
Just concerned with my GFR; I'm hoping it was because I didn't really have much water prior to testing and because I clearly needed an increase of levo for a while.
Thanks for the reply.
A TSH of 8.4 is very very high, so it could definitely be an explanation for any health problem.
Every tissue and organ in the body requires thyroid hormone, so almost anything can go wrong if we don't have enough. I've often wondered why different people seem to get different sets of symptoms. A biologist friend recently told me her opinion is that wherever we personally have weaknesses is where we'll start suffering for not having enough hormone.
26 is even higher lol..yep told me I was fine aha. I'll just drink loads on the day and hope for the best. It's affected me in many ways..but it shouldn't have been left to get so bad..thanks

Isn’t tsh the best indicator of thyroid hormone replacement due to TT
TSH decreasing and T4 increasing...
Yey! My kidneys have probably shrunk.
