When I have a bad flair up of my lyphocytic colitis, I experience waves of nausea. My Gastro says they are not related (do you realize how far away they are from from each other? he says, referring to the stomach vs. the colon). I notice a definate corelation. Many online articals, i.e. Mayo clinic, etc., say that a colitis attack can bring on "nausea, low-grade fever, flu-like symtoms and related weight loss." Mine Dr. continues to treat me for gastritis, performed an endoscopy (found nothing except some inflammation) and now has me on a time released antacid. Why do the doctors fight a relation between the two conditions.
