Well, I appreciate the update and am really glad the doctor is not concerned!! Thanks for sharing your story and the details. Check out the other forums--- great place to share what you know!
Oh, I'm really glad you booked your appointment. Come back and tell me what they say!
Any unexplained weight loss like that should be discussed with a doctor. Do you have a physical every year? I'm guessing not but now is the time! Have those boils looked at. I'm sorry I don't have more info for you but it is really something you need to be seen for. I personally would like to lose a bit of weight . . . but when it just happens like that, it can be worrisome. So, see a doctor and please let me know.
Some possibilities include diabetes, celiac disease, nutritional or metabolic issues, heart failure, cancer, depression, hyper thyroidism, etc. Without anymore information, it is hard to say so get checked out and let us know!
