Reading time: 2 min

The term Inflammatory Bowel Disease (IBD) refers to a group of inflammatory diseases that affect the digestive tract with periodic outbreaks of symptoms. The cause of the disease, which mainly involves ulcerative colitis and Crohn’s disease, remains unknown.

This chronic disease alternates between symptomatic episodes and periods in which the symptoms disappear after customizing medical treatment.These episodes are very unpredictable because their frequency and severity vary greatly. Nonetheless, 50% of patients present only mild symptoms and most of the time are asymptomatic.

How many people are affected by Inflammatory Bowel Disease?

Inflammatory bowel disease is more prevalent in developed countries and in the Caucasian population. It affects men and women in equal proportions. The disease can appear at any age; however it is most commonly diagnosed in people aged 20 to 30 years, with a second increase in incidence in people aged 50 to 70.

In Spain, it is estimated that 87–110 out of every 100,000 people are affected by IBD.
