Well I thought I would already be depleted of certain things as I have ulcerative colitis too, but it's not that bad atm (I'm not on steroids so weight is not that). I also asked for B12 to be tested which apparently is fine. Some kind of globulin thing was high, serum cholesterol is 4.42 mmol/L which I think is a bit high and my creatinine is high too.
I'm a teeny bit anaemic at 11.8 but I've been a 7 before and not this tired.
The weight thing is the one getting me down the most, I don't like leaving the house I'm so embarrassed. Which makes me even more tired!
Round here they just say their labs say 4.5 and over is hypo. My gp just thinks it's depression and colitis, but I know what I'm like when colitis is bad and it's not like this. Colitis is supposed to make you lose weight anyway. My GP is normally good and open minded but he says thyroid is completely normal. Is there any official UK body saying the levels are 0.3-3 or is it just internet talk? He's less likely to dismiss it then.
What made think thyroid though was I'm sure I went hyper after having my son as I went down to a size 8 (US 6) despite eating all day long, I was breastfeeding but that never made me lose weight before...I also lost a couple of fingernails and hair.
Then I went the other way up to a 12 (US 10) and feel so so tired. I can sleep all day if left be.
You're not subclinical based on your TSH -
You're hypothyroid. AACE guidelines are now .3 - 3.0 for the TSH so you can see your over the max range.
Now being hypothyroid - and getting meds - is NOT you're answer to your weight. You have to take into consideration the "long haul" you are in with being hypo. You're wearing your body down which is causing your body's metobolism to slow. Outward, your weight gain is your body telling you something is wrong.
Your other hormones are falling out of whack the longer you remain "off" and fixing that can be challenging - ( saying that in a nice way)
I would first, print out the new guidelines for your doctor on TSH. I would print out proper testing like FT3 and FT4. I would also start a mini research on the other hormones being effected if left untreated - i.e. adrenals, estrogen, progesterone, cholestrol. and then look up on how your body "could" reject and deplete in vit's and minerals - i.e. Vit B's magnesium - potassium - zinc - Vit D-3
You need to learn about all this and go back to your doctor to discuss what you've learned. Work as a team with your labs and symptoms and try to come together on how you can feel better.
If you or your doctor is going to base everything on a TSH and weight issues - then you could be headed for a very miserable long haul.
