Diseases of the bowels can really limit an active lifestyle. Not to be confused with the less severe irritable bowel syndrome (IBS), inflammatory bowel disease (IBD) is a group of diseases where the gastrointestinal (GI) tract are chronically inflamed. People with IBD can suffer from episodic or persistent symptoms that make it hard to carry out everyday activities. The most common forms of IBD are Crohn’s disease (CD) and ulcerative colitis (UC).1
Prevalence of IBD is highest in North America and Europe. In North America, UC affects 238 out of 100,000 people, while CD affects 201 out of 100,000.2 Asia has much lower rates of IBD than Western countries, though prevalence is increasing.2 Studies conducted in Singapore showed that the rates of CD rose dramatically from 1.3 in 100,000 in 1992 to 7.2 in 100,000 in 2003.3,4 Of the main ethnic groups in Singapore, the Indians are most susceptible to the condition, followed by Chinese and Malays.3,5
The cause of IBD is not known but genetics, the immune system and the environment all play a role. IBD symptoms can be affected by diet and stress, so lifestyle and nutritional changes might be able to help. At Nestlé Health Science, we devote a significant proportion of our research efforts to nutritional therapies for GI disorders, including IBD. In this way, we aim to help people manage their condition better.
Some people with IBD may be aware that certain foods aggravate symptoms. Commonly, symptoms can be made worse by dairy, fatty foods, spicy foods, caffeine and alcohol, and even too much fiber. Since IBD can cause restrictions in the GI tract, eating easy-to-digest foods is important. Following the dietary instruction for any medication is also crucial, as drug-food interactions can affect symptoms. And because undesired weight loss can occur, especially when symptoms flare up, people with IBD should ensure adequate nutritional and fluid intake through more frequent, smaller meals or nutritional supplements, if necessary.
