Summary:
Irritable bowel syndrome (IBS) has symptoms in common with other physical conditions. IBS ranges in severity from mild and infrequent episodes to more frequent,severe, longer, and more debilitating episodes. It is thus a chronic recurrent condition that for many patients in many healthcare contexts remains an undiagnosed pattern of recurrent, but different symptoms that are presented without much relief.
Often IBS is effectively managed in primary care with lifestyle management and monitoring and identifying of triggers. However, when IBS is not effectively dealt with in primary care, a patient may need a referral to a specialist. This article argues that first specialist who is considered should be a gastroenterologist, not a mental health professional.
Evidence is accumulating that IBS is often a disturbance in the gut-brain relationship. In that sense, it has a psychological component. But it is important to recognize that it is a matter of the gut influencing the brain by way of well-documented pathways.
IBS is increasingly seen as a disturbance in the microbiota or microbiome (I explain what that means below) of the gut. President Obama has directed the NIH to study the human microbiota or microbiome as part of a larger initiative studying these phenomena in other ecological systems, including soil. There is a lot of enthusiasm for this broad initiative, but also some caution that the enthusiasm should not get too far ahead of the data. I have added some links about this.
Anxiety and depression often accompany IBS. The symptoms may reflect the uncertainty and discomfort of trying to managing an ill-defined condition. But this distress also may be a direct effect of the gut on the brain, again through increasingly known pathways.
Patients with undiagnosed IBS challenge and ultimately frustrate physicians. When physicians cannot resolve their complaints, patients sometimes get mistreated and blamed for their condition.
Previous explanations for IBS focused on it being an expression of unconscious conflicts. Psychoanalytically oriented explanations suggest anal conflicts in which the patient struggles with hostility that she cannot express directly. IBS can been seen as a conflict between retaining in expelling fecal contents. Diarrhea or loose bowel movements can be seen as symbolically crapping on somebody in a situation where anger cannot be directly expressed. Such explanations are creative and even literary, but they are testable hypotheses about an individual patient. Such ideas just do not hold up in research studies, often because the hypotheses cannot be coherently expressed with key variables assessed with validated measures.
I’m not a physician and I’m not a position to offer advice to individual sufferers from IBS. But if I or a family member developed what looked like IBS, and it could not be brought under control in primary care. I would not recommend referral not to a mental health professional as the next step.
In the UK, IBS is considered a medically unexplained symptom (MUS). IBS patients are likely to be referred to psychological interventions for which there is only weak evidence. Patients with IBS may have to get educated on their own about the condition and fend for themselves in a medical system that is unresponsive to them.
Finally, some readers have attempted to leave comments on this blog post discussing benefits they sincerely believe they have received from treatments, including dietary supplements for which there is not scientific evidence. I have not accepted those comments for posting. I’m very skeptical of alternative and complementary medicine which is basically unproven medicine. I also see suffers from IBS vulnerable to exploitation by all sorts of deliberate or innocent quackery.
