Inflammatory Bowel Disease (IBD) is a gastrointestinal (GI) disorder[1] that involves long-lasting inflammation of your digestive tract.2 Although IBD is commonly considered a disease of young adults, it can occur at any age. There is a first peak onset of IBD at 15-30 and a second peak at 60-70.34 Patients aged over 60 account for up to 35% of all IBD cases in Europe and incidence is rising.4
There are two main types of IBD:[1]2
Although the exact cause of both UC and CD is still unclear, it is known that it involves a complex interaction between four factors:5
Genetics (family history)
The environment (e.g. a certain diet and lifestyle over a long period of time)
The immune system
Bacteria that live in the gut
None of these factors alone are likely to cause the disease.
Although both forms of IBD share many similarities, there are also some important differences such as the symptoms they cause.2

IBD affects around 4.3 million across Europe, and that number is increasing every year.6
The European Federation of Crohn's & Ulcerative Colitis Associations (EFCCA) is an umbrella organisation representing 45 national Crohn’s and Ulcerative Colitis (collectively known as IBD) patient associations.
Symptoms of IBD can come and go, sometimes without warning, and can be caused by triggers such as certain foods or stressful situations, which will be different for each person living with IBD. When the inflammation worsens, and you experience more symptoms of your condition, it is called a ‘flare-up’. The quiet or symptomless period of time between flare-ups is called ‘remission’. In children, IBD can be more severe than in adults, and can have different effects such as delayed puberty and growth rate impairments.789

However, the symptoms that occur in people with UC are very diverse. At the beginning of the disease, there may only be unspecific symptoms in the gastrointestinal area that seem harmless. If they occur more frequently and with increasing intensity, they can also be serious signals of IBD. Some people may also develop a low number of red blood cells (anaemia) or problems with their joints, skin and eyes.13
Remember to always talk to your doctor to get advice if you are experiencing symptoms, especially if there has been a sudden change.
