My osteopenia is now osteoporosis. I read recently that this could be from malabsorption because of the pouch. Just to make matters worse I'm on letrozole for breast cancer which is known to cause osteoporosis. Is anyone else having problems with osteoporosis? I'm a pretty active 62 year old. I exercise almost everyday and I eat healthy foods. I've had a pouch since 1988. Also, for you newbies, this might be something to talk to your doctor about. I just read about this in an article that was published this spring.
