Psychological issues in patients with inflammatory bowel disease should be addressed at both personal and systemic levels, according to a review of current literature.

In a review published in the Journal of Clinical Gastroenterology, researchers highlighted data on the burden of mental disorders in inflammatory bowel disease (IBD) patients and presented several strategies for addressing them.
“From a systems perspective, underrecognized and/or suboptimally treated mental health problems in patients with IBD are associated with increased disability, poorer adherence, and more admissions and surgeries, driving increased health care utilization and costs,” Maia S. Kredentser, PhD, of the University of Manitoba, Winnipeg, and colleagues wrote, citing a 2018 study’s findings.
“There is ample evidence for a higher prevalence of mental disorders in IBD, in particular depression and anxiety, compared with the general population,” the authors wrote.
They cited a recent population-based study in which the incident rate ratios were significantly higher for IBD patients, compared with matched controls for depression (IRR, 1.58), anxiety disorder (IRR, 1.39), bipolar disorder (IRR, 1.82), and schizophrenia (IRR, 1.64).
Mental disorders associated with IBD also include issues of body image and sexuality. Although research on the impact of disease activity on sexual function is inconsistent, one study suggested that body image “may be an important target of treatment in women reporting poor quality of life and psychological distress,” the researchers noted. A French study from 2017 published in the Journal of Crohn’s and Colitis showed that approximately half of men and women reported problems with erectile or sexual dysfunction.
Issues related to environmental stressors may contribute to IBD by promoting chronic inflammation, the researchers wrote. For example, data from longitudinal, population-based research suggest that adverse childhood experiences can promote proinflammatory states across inflammatory illnesses. Research has also suggested that people with IBD have higher rates of these adverse childhood experiences than the general population. However, data also show that many are able to cope and adapt: “Many patients with IBD are resilient, experience growth, and in fact, thrive,” the researchers added. One longitudinal study suggested that patients with IBD who identified with “thriving” had “stronger coping efficacy (the perceived ability to meet illness demands), illness acceptance, and social support and lower depression” and that this was associated with life satisfaction 6 months later.
Fatigue also has been shown to be a factor for patients with IBD. The researchers cited one population-based study showing fatigue in 57%-72% of IBD patients with active disease. IBD patients with quiescent disease also report fatigue. The psychological and behavioral factors driving fatigue could be related to mental disorders or other factors such as suboptimal sleep, stress, and use of caffeine and alcohol, they noted. Management strategies include improving sleep hygiene and evaluation of mental health concerns.
Seek complete picture before treatment
“Addressing psychological comorbidity in IBD requires individual and systemic approaches focused on both the prevention and treatment of mental health concerns,” the researchers wrote. “Because of the pervasiveness of psychological comorbidities in IBD, and recent evidence that they may be part of the disease process itself, assessment of psychological functioning in IBD is considered an essential aspect of disease management.”
Evidence-based psychological interventions include cognitive-behavioral therapy, which includes training in relaxation; treatment with clinical hypnosis; and encouraging mindfulness through acceptance and commitment therapy, which focuses on developing psychological flexibility to cope with suffering. In addition, a small but evolving body of research shows some benefit to motivational interviewing (a strategy focused on behavior change) for IBD patients. Notably, one review of four studies showed benefits of motivational interviewing for improving medication adherence and advice seeking, the researchers reported.
Although several psychological treatment options exist for addressing mental health issues in IBD, randomized trials are needed. “To facilitate this important research and optimize patient care, the integration of psychologists and other mental health providers into IBD care is considered best practice and provides exciting opportunities for improving patient care and outcomes,” the researchers concluded.
Address mental health to ease disease burden
“There is a large burden of mental health issues in patients with inflammatory bowel disease, with depression and anxiety leading the way,” Kim L. Isaacs, MD, of the University of North Carolina at Chapel Hill, said in an interview.

“There are multiple reasons for this, including dealing with chronic pain, social concerns around using the bathroom, body-image issues due to surgery, and drug side effects. There is increasing evidence that the inflammatory process in IBD may be driving some of the changes in the brain which lead to further mental health dysfunction,” she noted.
“Addressing depression, anxiety, [and] sleep disturbance in patients will not only improve quality of life from a mental health perspective but has been shown to improve control of disease,” Dr. Isaacs emphasized.
“Small things like increased medication compliance have a large impact on disease management and decreased need for hospitalization and hospitalization,” said Dr. Isaacs. “As gastroenterologists we need to expand our focus beyond the gut and address the emotional needs of our patients – identifying those patients who need increased mental health support.”
Barriers to better care
The greatest barriers to treating mental health issues in IBD patients are time and knowledge, said Dr. Isaacs. “Many gastroenterologists have limited time in the office to do more than address the acute issues of the patients such as rectal bleeding and worsening diarrhea. It takes time and trust to explore what is going on in a patient’s life. Is the patient anxious and depressed? How are they coping with their current disease manifestations? Simple screening tools may help with this, but then there need to be resources to support interventions.”
Some IBD practices, especially academic ones, have a psychologist in the IBD center or one that’s readily available for consultation. “This is an investment for the practice that may reduce significantly disease burden. The IBD specialty home model includes resources for management of psychiatric issues and nutritional concerns as well as disease management,” she added.
More research in several areas can help reduce the mental health burden of IBD. “On the immunology/biology side, understanding how the microbiome affects the brain/gut may allow for more directed mental health treatment. On the disease management side, larger trials directed at psychiatric interventions may help to determine which therapy is best for each patient,” Dr. Isaacs said. “Further work developing health care systems, such as the medical home, that allow for maximum disease management and decreased system costs will go far in implementation of models of care that address the needs of the entire patient with inflammatory bowel disease.”
The review received no outside funding. The researchers had no financial conflicts to disclose. Dr. Isaacs disclosed consulting on the data safety monitoring board for Janssen.
