Im having bypass surgery at NHS Ninewells soon. I have been waiting 2yrs come September and had to lose 10% of my body weight . I am hypothyroid, insulin resistant, vit D deficient, have fibromyalgia and several other problems . I am having barium swallow and camera down throat in August, getting ready, and been on hold for thyroid to get stable. I have been on low carb diet for nearly 2yrs . I visit dietician at Ninewells every 6wks or so from the very start. so lets hope wont be too much longer
