hi i am blood group reeces negative A and have found out that that blood group can suffer from high cortisol. I have recently in the last 3 years put weight on around my stomach not really anywhere else, have excessive night sweats, am always tired but find it hard to get to sleep. I also occasionaly am light headed. I was tested about 3 years ago for hormone imbalance as i sweat quite alot and it came up negative so am worried my doctor will think i am wasting his time. Any suggestions? thanks
