Subclinical hypothyroidism should be checked out for both you Sunnydays and you Peroxideblader. If there is a pituitary problem it needs to be discovered in case it can be solved or in case it's causing other issues by lack of signalling. Whatever the outcome, both of you should be given a trial of Levothyroxine, the treatment is the same whatever the type of hypothyroidism. In your case Sunnydays, your antibodies mean you have an autoimmune thyroid condition (Hashimoto's thyroiditis - but NHS just call it autoimmune). Again the treatment is the same, Levothyroxine, but the aim to to keep the TSH very low, well below 1, to try to keep the antibodies low. Peroxideblader, you need your antibodies testing, both kinds. Good luck at the doctor appointment. I understand why you are taking your partner now. Sometimes just having a second person in the room makes the GP sit up and take a bit more notice. If you can, get a plan together with your partner before the appointment. If the outcome is a referral then the plan is to ask for that and give your reasons. If the outcome you want is a trial of Levo. then both of you should put your heads together and work out what you are going to say to get that result.
