Definitely have them check your thyroid levels. I will say that sometimes, for reasons unknown, some people really struggle with weight. I eat an excellent diet and exercise and I have to fight HARD to maintain my weight. I'm still about 15 pounds more than I want to be. I do know that there is something to be said for adequate sleep and weight loss. You could have irregular sleep pattern or sleep apnea and not know it. There is also something to be said for not eating late at night either (not that you do). (Just some thoughts though these aren't Endo things). You seem to be female (?) so you can also ask him to evaluate you for PCOS or polycystic ovarian disease (or syndrome). I don't know if you have other clinical signs of it our not but insulin resistance and being overweight are two common signs. I live in the States so I don't know if your Endos do PCOS or if that is a GYN or both. ???? The Endo can check your cortisol level for you. You are right, it could be elevated due to stress. If it is related to stress there isn't likely anything they would do medically since increased production of cortisol is natural to stress.
