Crohn's Disease (CD) is frequently associated with weight loss and malnutrition. However, as prevalence of obesity increases worldwide, it may become a clinical problem even in CD patients.
A retrospective analysis of a computerized CD patients' database was performed to identify severely obese patients (BMI > 35). The prevalence of severely obese patients was compared to data of the general population (Mabat national survey). These patients were then compared to randomly selected non-obese CD patients (BMI < 30) in a 1:3 ratio, respectively.
Thirteen severely obese patients out of 560 CD patients were found (2.3%), significantly lower than the prevalence in the general population (5.6%, P < 0.001). When compared to 39 non-obese CD patients, colonic disease was significantly more prevalent in severely obese CD patients (OR 7.3, 95% CI 1.8–29, p = 0.004), while complicated CD was less common in those patients (OR 0.25, 95% CI 0.07–0.92, p = 0.04). After adjustment for age, gender and smoking status only colonic disease remained associated with severe obesity (OR 5.7, 95% CI 1.3–24.65, P = 0.02). Notably, four of the severely obese CD patients had undergone laparoscopic sleeve gastrectomy for treatment of morbid obesity with a favorable surgical outcome.
Severe obesity is infrequent yet possible in CD. CD in severely obese patients is more often colonic but otherwise indistinguishable from non-obese patients. Sleeve gastrectomy is a viable therapeutic option for morbidly obese CD patients.
