I have been hypothyroid since birth of my son 16 years ago and was fairly well controlled on thyroxine 125 mcgs up until about 18 months ago. Have been very unwell last 6 months with extreme fatigue and sleep apnoea and my quality of life has definitely deteriorated. My GP has put it down to work related stress. TSH levels only done and within normal range Referral to endocrinologist therefore was not recommended by my GP. I am fairly sure my symptoms are related to my thyroid and would be keen to see a specialist.
