I started on Thyroxine 25mcg a year ago. 3 months ago my GP increased it to 50mcg. I'm due another test next month, but recently my weight is surging upwards with no change in my eating habits, and in fact I'm cutting down and it still goes up. I have other symptoms too such as tiredness, pins and needles, hair loss.
Has anyone else had this happen to them, is it really possible to have a rapid weight gain if the levels are low, or am I just making excuses?
