I'm having the same problem. Lost 36 pre-op. Then lost 11 lbs in first 2 weeks. Now I'm 5 weeks out and have only lost 5lbs in the last 3 weeks. I am exercising and eating as the doctor says. I feel like this too is failing, as every other thing I've tried. I also have to take replacement thyroid hormones because they killed my thyroid 8 years ago. So I'm wondering if anyone else has thyroid trouble and is further out. Could you tell me if this surgery worked for you, even though your thyroid doesn't work? Did you have slow weight loss, at the beginning?
