Is diverticular disease caused by straining only for bowel movements, or would straining in the absence of stools also cause this?

..: diverticulosis is an outpoutching colonic wall that is a results of weakness along its walls. this can be exacerbated by any increase in intra-abdominal pressure which includes straining. this is unrelated to actual stools, yet constipation can increase diverticular disease due to straining. make sure you get plenty of fiber in the diet and drink plenty of fluids to decrease likelihood.
