Hoping someone here has an answer to this question. My husband has been having terrible pain on his right side under the rib cage. He thinks it is his gall bladder after talking to his doctor and other people who have had gall bladder problems. He recently lost weight while trying to lower his cholesterol. So many people we have talked to said that they started having gall bladder trouble after losing weight. Why is that? You would think that eating healthier (lower fat and cal.) would help the gall bladder not work so hard. Has anyone else had this experience?
