IBS-Digestive Health

IBS or Irritable Bowel Syndrome is estimated to affect 10-15% of Americans based on population studies. According to a John Hopkins Study, it is the second leading cause of work absenteeism after the common cold.

Symptoms include:
  • Chronic Abdominal Pain
Can be described as crampy, "gassy," frequently on the lower left side of the abdomen but the location can vary widely, gets worse from time-to-time, can be relieved by a bowel movement. 
  • Altered Bowel Habits
Diarrhea dominant; constipation dominant; or alternating between diarrhea and constipation. 
  • Other Digestive Symptoms
Includes bloating, gas, belching, feeling full very easily, fullness in the stomach or abdomen. 

Someone doesn't need to have all of these symptoms to have IBS. 

These symptoms can limit quality of life. People can end up feeling tired all the time and have the mental stress of not being able to predict when they will feel OK or when their IBS may act up. 

I see many patients who had been diagnosed with IBS previously and were advised to simply "eat more fiber," "reduce their stress levels," and "exercise more."  While these are all good recommendations for overall health, there are many patients to follow these advice but still do not feel better. Indeed, IBS is a complex medical condition. 

It is important to work with a clinician who has worked with a lot of IBS patients because IBS symptoms may mimic other conditions that are not IBS and may have to be treated differently.

In women, abdominal-pelvic symptoms have to be differentiated from gynecologic issues that may be mistaken for IBS; examples may include dysmenorrhea, painful ovarian cysts, urinary/cystitis pain. If a female patient has not had a gyn exam recently, or if the suspicion is high that the pain may be gynecologic in origin, I will usually refer to a gynecologist or one of the doctors in our clinic specializing in gynecologic health for a consult. 


Why Schedule a Visit to Treat IBS?

The first visit lasts 1 hour. Typically we do the following:

Interview
  • What are the symptoms? How long? Where is it located? What makes better or worse?
  • Diet Recall
  • What type of Lab work had been done in the past? Colonoscopy? Endoscopy?
  • Then, specialized questions...
Physical Exam If Needed

Labs
These are the tests I would typically order:
  • Celiac or gluten-sensitivity testing
  • Food Allergy Testing OR Eliminaton-Challenge Diet Protocol
  • Tests for inflammation such C-reactive protein, Calprotectin; if these are elevated, we need to explore if there is possibility of inflammatory bowel disease such as Crohn's or Ulcerative Colitis
  • Stool test to check for parasites
  • Levels of "good bacteria" versus "bad bacteria"
  • Stool test to check for yeast/candida
  • Stool test to check for blood
  • Stool test to check if patient is producing adequate amounts of digestive/pancreatic enzymes
  • Stool test for H. pylori if needed
  • Consider lactose intolerance testing
These may sound like a lot of tests, but I've worked out a system to make it simple for patients. Usually, we can get the above information with a blood draw plus a stool test.  We use Labcorp and Genova Diagnostic Services for these tests.
