Hi - I am desperately looking for advice please? A couple of months ago I went to my GP with a sore front of my throat and had a blood test done as he thought it was my thyroid, the result came back : Free T4 <5.0 *L (9-24) , TSH 75.86 *H (0.34-5.4) - and he put me on 50mg Levothroxin. I had another blood test done after the 6 weeks and just got the results which are Free T4 7.5 *L (9-24) , TSH 71.61 *H (0.34-5.4) : he has upped my Levothroxin to 100mg daily as of yesterday! Can someone explain what this all means : I had been feeling pretty tired of late with dry skin and my hair was feeling thinner but seems like this is just been in the last couple of months or would this have been an issue my body has had for some time? And I have read taking Levothroxin causes weight gain is this true? What else can I do to help my body gain equilibrium ie can I add supplements to help? Any advice would be great as i have no clue!
