Abstract:
A prospective epidemiological study on inflammatory bowel diseases (IBD) patients was performed in Brussels' area from April 1st, 1992 to 30th March, 1993. The mean annual incidence for Crohn's diseases (CD) was 4.1/10(5) inhabitants/year among native Belgian people and 6.4/10(5) inhabitants/year for subjects issued from Moroccan families. For ulcerative colitis, the incidence was 3.7/10(5) inhabitants/year for native Belgian people and only 1.2/10(5) inhabitants/year for Moroccan subjects. The male/female sex ratio was 0.4 for CD and 1.9 for UC. At the time of diagnosis, the mean age was 34 years for CD and 38 years for UC. For both diseases, the age peak was between 20 and 29 years. Cigarette smoking was significantly higher in CD (48%) than in UC patients (12%). Family history was about 10% for both diseases.

Chronic Bowel Disorders: Introduction
Irritable Bowel Syndrome (IBS) is a common disorder affecting the gastrointestinal tract. The distinctive feature is recurrent abdominal pain associated with altered bowel movements, manifesting as constipation, diarrhea, or fluctuating between both. The...
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 transmural...
