Woo! Tests came back, I do not have tumors on my thyroid! I'm so happy. I do have a low thyroid, and high cholesterol. I have been tracking what I eat and the doctor agreed the weight gain is mostly from the thyroid and stress. I have cut back on chocolate though, lol. The cholesterol comes from the low thyroid. I showed him my diet. Besides eggs, I eat mostly low cholesterol foods and very little red meat. He said that peopel with a low thyroid often has problems with cholesterol. I have been put on thyroid hormones and cholesterol meds, and already I am feeling so much better, and the weight is coming off much easier. I dropped ten pounds in 3 weeks and I am no longer exhausted after just a few minutes of exercise. This is also helping with my emotions. I was depressed with the sudden weight gain, and I feel vindicated that much of it was coming from something medical. Still, I have been more careful about what I eat and making time for the gym. If only for one reason, it would be that it just makes me feel better. I will never get rid of the stretch marks from teh rapid weight gain, but I can at least get back my energy and the sense of control over my life.
