Aim:
To classify changes over time in causes of lower gastrointestinal bleeding (LGIB) and to identify factors associated with changes in the incidence and characteristics of diverticular hemorrhage (DH).
Methods:
A total of 1803 patients underwent colonoscopy for overt LGIB at our hospital from 1995 to 2013. Patients were divided into an early group (EG, 1995-2006, n = 828) and a late group (LG, 2007-2013, n = 975), and specific diseases were compared between groups. In addition, antithrombotic drug (ATD) use and nonsteroidal anti-inflammatory drug (NSAID) use were compared between patients with and without DH.
Results:
Older patients (≥ 70 years old) and those with colonic DH were more frequent in LG than in EG (P < 0.01). Patients using ATDs as well as NSAIDs, male sex, obesity (body mass index ≥ 25 kg/m(2)), smoking, alcohol drinking, and arteriosclerotic diseases were more frequent in patients with DH than in those without.
Conclusion:
Incidence of colonic DH seems to increase with aging of the population, and factors involved include use of ATDs and NSAIDs, male sex, obesity, smoking, alcohol drinking, and arteriosclerotic disease. These factors are of value in handling DH patients.

Inflammatory 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...
Inflammatory Bowel Disease II: Crohn's Disease
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...
