Background:
The incidence of inflammatory bowel disease is increasing in Europe and in Spain. However, there is no recent data from Southern Spain.
Objectives:
To determine the evolution of the hospital incidence of inflammatory bowel disease in Southern Spain.
Material And Methods:
A retrospective study was performed in two hospitals in Southern Spain. Data was collected from inflammatory bowel disease patients, divided into two periods (1995-2000 and 2001-2014) and compared. The reference population from both areas was 1,011,555 inhabitants.
Results:
A total of 430 patients were registered during the first period (1995-2000); 50% (215) had Crohn's disease that resulted in a cumulative incidence rate of 7.08 cases/100,000 inhabitants per year. The overall inflammatory bowel disease incidence was 3.54 cases/100,000 inhabitants per year. During the second period (2001-2014), 2,089 patients were collected; 51.7% had ulcerative colitis (1,081). The rate of cumulative incidence of inflammatory bowel disease was 14.7 cases/100,000 inhabitants per year (7.6 cases of ulcerative colitis/100,000 inhabitants/year and 7.1 cases of Crohn´s disease/100,000 inhabitants/year).
Conclusions:
The incidence of inflammatory bowel disease in Southern Spain has doubled in the last decade and is similar to that of the rest of the country and Europe.

01:30Inflammatory 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...
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...

Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...

01:17Gastritis-II: Pathophysiology
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...
