GI Psychology Service

There is a very close connection between the brain and gut. As a result, many gastrointestinal (GI) disorders are affected by how we think and feel, and in turn can be helped by psychological and behavioral approaches.  When we are stressed, worried or depressed, it can worsen gut symptoms like abdominal pain, diarrhea, and nausea, which can then worsen stress and anxiety, and so on. As well, diseases of the gut such as inflammatory bowel disease (IBD) and celiac disease can be very challenging to manage. 

The most common GI disorder, irritable bowel syndrome (IBS) involves symptoms of pain in the lower abdomen, changes in bowel habits with frequent, urgent diarrhea or constipation, bloating, and cramping.   This disorder of the lower ‘gut' or gastrointestinal (GI) tract is thought to occur because of disruptions in communication between the brain and the gut. Research suggests that people with IBS experience abnormal gut motility (an altered rate of contraction of the gut muscles) and enhanced visceral sensitivity (an increased awareness in the brain of normal gut activity as well as painful distensions in the gut).

Description of services and treatment

Research has shown that psychological treatments are effective in providing relief of GI symptoms as well as in reducing the distress and coping difficulties that often occur when dealing with a chronic illness. These strategies focus on ways to decrease stress and cope differently so that the stress doesn't ‘go to the gut'. Cognitive behavioral therapy incorporates a number of tools aimed at changing behavior to improve health and strengthen resilience.

The approach commonly includes daily symptom monitoring, educational information about the GI disorder to ensure a better understanding of the illness, relaxation training to learn how to calm the gut, as well as training in strategies that increase psychological flexibility, checking and challenging thought patterns and distressing thoughts that can lead to gut reactions.
