I first came on here 4 years ago because I wondered whether I had underactive thyroid. At that time my TSH was 1.56 and T4 was 13. They were the only results I had and was told they were normal.
Last week I asked for bloods to be done again as I feel much worse and so tired all the time. I am also cannot lose any weight despite trying very hard. I have been taking my basal body temp for a couple of weeks and that's always lower than it should be .... It's hardly ever been 36.5.
Got my blood tests today and receptionist again says they are normal at TSH 2.10 and T4 at 12. Where do I go from here. Any advice very welcome. Thanks.
