I was diagnosed in May as hypothyroid, I was put on 50mg Levothyroxine but don't feel any better at all, my medication was then increased to 100mg a week ago. Since taking this, I feel a lot better - I'm still not myself but managing to get through each day however, I have put 4lb on in a week and my diet has not changed. I sort of expected to lose some weight as I have been so active this week compared to the last few months. I feel so bloated, almost as if someone has injected me with water everywhere. I'm feeling so upset by this and my hair has thinned too. I'm so frightened of becoming a fat bald old woman! Has anyone else experienced ths since taking Levothyroxine?
