SUSAN LUCAK, MD: The alarm symptoms and signs include weight loss, anemia, elevated white blood cell count, elevated sedimentation rate, again, suggesting inflammation or infection. Electrolyte abnormalities in the blood; again, suggesting that in those patients who have diarrhea, that the diarrhea may be more significant, leading to dehydration. Family history of colon cancer, or inflammatory bowel disease, such as Crohn's disease or ulcerative colitis.
Also when patients have nocturnal symptoms. Generally, when people with irritable bowel syndrome go to sleep, their gut goes to sleep and they generally do not have symptoms at night.
ANNOUNCER: When red flags are present, or a patient is 50 or over, doctors will usually examine the colon with an imaging device. But otherwise, research suggests such diagnostic tests are not necessary on a routine basis.
In fact, in diagnosing IBS, doctors have shifted focus in recent years to what IBS is, rather than what IBS is not.
BRIAN LACY, MD: It's been taught for many, many years that irritable bowel syndrome is actually a diagnosis of exclusion. That a patient should have multiple tests, extensive testing, repeated visits before a diagnosis can be made. One of the things we try to teach here is that irritable bowel syndrome is actually a fairly easy thing to diagnose. That when somebody comes to our office and has these complaints, there are no warning symptoms on exam or by history, we should be able to make a diagnosis that day. And really start treatment on that first visit.
ANNOUNCER: Perhaps the most important factor in promoting IBS diagnosis is a good relationship between doctor and patient. In fact, trust and communication can help bring about the best results as newly-diagnosed patients turn toward treatment.
LIN CHANG, MD: You really do need to spend time with patients to get to know them and to understand what their symptoms are, how they cope with it.
I think it's very important to have good communication between a patient and a physician, to build that sense of trust, that bond.
BRIAN LACY, MD: Make an appointment to see a doctor. Don't be squeamish about telling the doctor your symptoms. Tell them what the symptoms are and be very upfront about it; don't hide it. And follow-up with the rule, the question to the doctor saying, "I have these symptoms now, what can we do about it?"
