Research is still uncovering the causes of and triggers for irritable bowel syndrome (IBS). Many lifestyle and environmental factors affect both the emergence and severity of IBS, including alcohol abuse,1,2 depression,2 psychiatric stress,3,4 and more. Knowing the right questions to inform your patient history rapidly builds the patient relationship as well as improving your diagnostic skills.
One study of military personnel found that an important antecedent for many cases of IBS is previous infectious gastroenteritis, which increases risk by two to three times versus controls. Furthermore, a range of cognitive factors affected the risk of emergence of IBS, including post-traumatic stress disorder (PTSD), depression, life stress, and self-reported anxiety. Significant interactions were found between infection, depression, anxiety and the later emergence of IBS.4
The study did not intervene to treat IBS, but the biopsychosocial model described by the authors suggests that a variety of lifestyle interventions may reduce IBS severity. In addition, restoring a healthy microbiome and reducing gut permeability are known to be crucial for treating IBS.5-7
In a disorder such as IBS, the gut-brain connection has a powerful impact. Without adequate attention to the emotional needs of patients, co-occurring psychological and biological issues go unaddressed. By evaluating lifestyle and medical factors, a treatment plan that deals with each area of patient life makes symptoms more manageable.

The gut-brain axis is the bidirectional communication between the gut and the brain, which occurs through multiple pathways that include hormonal, neural, and immune mediators. Interestingly, the signals along this axis can originate in the gut, the brain, or both, with the objective of maintaining normal gut function and appropriate behavior.Read More
Oral exams can reveal signs and symptoms of more than 90% of systemic diseases. However, in spite of these associations, some researchers feel there is a lack of awareness in the healthcare community on their possible importance. What do Functional Medicine practitioners look for within the oral cavity to assess overall health?Read More
