I have been taking Levo for 3 weeks now (gradually increasing the dosage to 100mg). I have put on weight of 4kg. I had expected to lose weight. I have hypo (Hasimoto's they think). I don't know what I can do to take control and stop the weight gain. There is lots of info out there but very confused. Before treatment my blood test showed a LDH of 200 and TSH of 9,81 other than those the T3 &T4 came back within range. Anyone suggest how to cope with the weight????
