Help

hi, im needed some help if possible

I have taken  Levothyroxine  for about  6 yrs now, i take 125g, i  also had radio therapy bout 3 yrs ago, i have had regular blood tests , all tests have returned all fine, i eat a balanced diet, fruit, veg, not much fatty food, i dont smoke and only drink at weekend, i swim 3 times a week, cycle a couple times, but i have found lately that my weight has gained and just feel so tired, like i just cant be bothered doing things, i feel what ever i eat im just gaining weight and whatever i do nothing seems to help to keep the weight off, it beginning to depress me now and make me unhappy

any suggestions would be very welcome

thanks

Darren, Inhave a similar set of symptoms, that are proving intractable. My only suggestion would be to see an endocrinologist if you have not already done so.
