Hi - I have been hypo for about eight years. Thyroid still works a bit now and again so was on 75mcg of Levothyroxin. That kept my T4 high and TSH almost off the scale but my cholesterol was good and I felt OK ish. Last year I got really achy and asked GP to test vit. D. That was pretty low so I got tablets that brought it right back up. At my next thyroid test my T4 was 29 (10-23) and TSH was 0.48 (0.25 - 5). About six months ago I was feeling jittery and aching again, anxious and not sleeping so thought maybe I was taking too much Levo (GP always telling me that results were too high), so I dropped to 50mcg. Have just had a load of bloods taken and would like an opinion on the results;
T4 is 21.5 (9-23)
TSH is 1.72 (0.25-5)
B12 is 268 (191-663)
Folate is 8.1 (4.8-37.3)
Cholesterol 7.11 (way up on last time)
Recently I've put on weight, very anxious, not sleeping more than 4 hours at night, muscular pains and terrible memory/absent minded. If I go back to 75mcg, are the B12 and folate too low? My GP thinks thyroid levels are perfect and B12 is fine which is why there is no point in my raising this with her. If I need folate, how can I get this?
