My girlfriend 23 years old. A year ago she weighed 105 pounds. Today she is 145. She has been for every test you can imagine. Her diet is impeccable. She eats way better than your average American. Her favorite food is a greek salad... Seriously, Salad. In April she had a cyst removed from her ovary, they believed at the time she had PCOS. However since then she hasnt lost any weight despite diet and exercise. Her last test results show she does not have cushings syndrome... Shes been to about half a dozen endocrinologist s who agree she thyroid is normal. Do you have any idea what this could be?
