I'm a 58 year old female, was healthy; O negative blood type; naturally acidic; breast cancer 2 years ago - no radiation or chemo; hiaetal hernia repair and then gall bladder removal from pancreatitus within 6 mos of each other. Without much notice I get very hungry, can't eat very much and become very bloated. Also, I have gained about 20 lbs in 6 months. What is going on?
