The relationship between the symptom of fatigue and the functioning of patients with inflammatory bowel diseases after surgery.

Introduction: The occurrence of fatigue in patients suffering from inflammatory bowel diseases (IBD) is influenced by pain, frequent bowel movements, stress associated with symptoms and time of their occurrence reaction of surroundings, fear for their own health, sleep disturbances, side effects of pharmacological treatment, physical and mental exhaustion, hindered social contacts and difficulties at work.

Aim: To evaluate the fatigue and the assessment of functioning of patients with IBD, who were treated surgically.

Material And Methods: To evaluate the functioning of patients, a Polish version of the Inflammatory Bowel Disease Questionnaire was used. To evaluate the occurrence of fatigue in studied subjects, a Polish version of the Functional Assessment of Chronic Illness Therapy - Fatigue Scale was used. The activity of disease was evaluated with the use of the Crohn's Disease Activity Index for patients with Crohn's disease (CD) and the Clinical Activity Index for patients with ulcerative colitis (UC).

Results: Before surgery, there was no significant difference between CD and UC patients, with regard to the mean FACIT-F (28.76 for CD and 28.76 for UC, = 0.72). Also, after surgery, there was no significant difference between CD and UC patients, with regard to the mean FACIT-F (14.8 for CD and 16.0 for UC, = 0.71). The IBD patients who underwent surgery for CD and UC had significantly lower FACIT-F scores compared to the patients before the surgery ( = 0.001 and = 0.0001, respectively). IBD patients who underwent surgery for CD and UC had significantly better functioning and higher IBDQ total scores compared to the patients before the surgery.

Conclusions: Surgical treatment significantly reduces the fatigue symptom in patients with IBD. The severity of fatigue correlates with disease activity and functioning in the respective areas.
