Background:
Whether uncomplicated diverticulosis gives rise to symptoms is controversial. Diary-based studies of abdominal pain and stool habits in general populations are scarce, and we therefore investigated symptom patterns in diverticulosis from prospectively collected symptom diaries in a random sample of the general population who completed a research colonoscopy.
Methods:
In the Swedish population-based colonoscopy (PopCol) study, 745 individuals from the general population underwent a colonoscopy of which 130 had diverticulosis, and none had diverticulitis. Seven-day symptom diaries were completed by 258 participants (age 54, women 64%) of which 50 had diverticulosis. The frequency and location of abdominal pain, bowel habit and other gastrointestinal symptoms were compared between individuals with and without diverticulosis using logistic regression.
Key Results:
Diverticulosis was not associated with abdominal pain (OR 1.24, CI 0.61-2.55) or left lower quadrant (LLQ) abdominal pain (OR 1.59, CI 0.73-3.49). Pain duration and severity were not associated with diverticulosis. When individuals with diverticulosis had pain, it was more often in the LLQ (OR 2.45, CI 1.02-5.86) compared with those without diverticulosis. Diverticulosis was not linked to altered bowel habits. Irritable bowel syndrome prevalence was 16% in the diverticulosis group and 19% in the non-diverticulosis group.
Conclusions And Inferences:
Participants with diverticulosis did not report more abdominal pain or more LLQ abdominal pain than participants without diverticulosis. Bowel habit was not abnormal in diverticulosis. Our results do not support that uncomplicated diverticulosis cause symptoms in individuals without a history of acute diverticulitis.

Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...
01:27Inflammatory Bowel Disease I: Ulcerative Colitis
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
