Last week I was diagnosed with an overactive thyroid following blood tests. Apparently it is not crazily overactive but enough for the need to take action. I have to wait until 29th December for a visit to the endocrinologist at the hospital but the doctor mentioned starting me on carbimazole before that. Reading about this online has TERRIFIED me, not least the huge amount of weight that dozens of people have reported. I've also read medical reports stating that significant weight gain is a common side effect and diet and exercise cannot touch it. I am only 5ft 2, have never been above a size 12 and am utterly terrified of "ballooning" having read many accounts of people's misery on this drug. I have a very public facing job and just could not face work were I to balloon. Many people are also talking of utter exhaustion on it. I have a newborn baby and a two year old so this is not an option for me. I will also be working full time come March. I bought lots of supplements today after research. I would welcome anyone's advice/experiences. I have worked myself into a total state.
