Obesity, Not Diet, Linked to Colonic Diverticula

Obesity, not a low-fiber diet, is more strongly associated with colonic diverticula. 

Reporting at Digestive Disease Week 2016, researchers said they had looked at patients undergoing first-time screening colonoscopy at the University of North Carolina Hospital in Chapel Hill, NC. 

Patients were examined for colonic diverticula. 

Of the 451 study participants, 193 (43%) had one or more deverticula (the mean number was 14 and the high number was 158).

Those who did were older, more likely to be male and to have a higher body mass indix and wast to hip ration as well as waist circumference.

The team found no relationship between eating a high fiber diet and the presence or absence of diverticula.

Patients who were obese had a 3.1 times higher risk of diverticula compared to those of a normal weight.

Having a big waist measurement  confered a 1.9 times greater risk. 

"Dietary fiber intake ws not associated with colonic diverticulosis; obesity, particularly abdominal obesity, significantly increased the risk of diverticulosis," the researchers said.
