I have been diagnosed by a regular md for gerd and gastritis. Taking an acid blocker which stopped my appetite somewhat. Forcing myself to eat. Losing weight fast without trying. Is this the sign of colon cancer?
Welcome to the gastroenterology community! This is probably not colon cancer. I would get an appointment with a GI doctor to help figure out what is wrong. In the mean time, you should talk to your regular md about switching acid blocker medicines because it might be causing your nausea. You also might want to try drinking something like ensure to help you maintain your weight when you are nauseous. Good luck.
