Hi I'm 27 years old, used to be super fit and slim but over the past few years I have gained over three stone without changing my diet. I have tried dieting but my weight stays the same/I get heavier. I am exhausted all the time, have a severe lack of motivation at times, depression and I suffer from anxiety disorder. I have been getting recurrent throat infections/swollen glands for years, kidney infections/upper UTI's. I had unbearably heavy periods for years until I got the implant which has thankfully almost stopped my periods completely. In the winter I am extremely sensitive to the cold, my hands seize up and fingers go numb. I have extremely dry hands uncomfortable hands, deep muscle/joint pain in my elbows and hands. My hair falls out in huge clumps in the shower and is always blocking the plug hole. I have almost lost half of my left eyebrow. I get hot flushes and sweaty whenever I exert myself. My grandfather suffered from an underactive thyroid. I am getting blood tests to check my thyroid next week and I'm feeling a bit anxious about it.
