Understanding Crohn's & Colitis

Who Gets IBD?

Inflammatory bowel disease (IBD), including Crohn’s disease and ulcerative colitis, affects people of all ages, genders, and racial and ethnic backgrounds. The disease is found throughout the world.

How many people have IBD?

Crohn's disease and ulcerative colitis, affects about 1 in 100 Americans and millions of people worldwide. More people are diagnosed with IBD every year, making it a growing health concern around the world. While IBD can affect people of any age, race, or background, it is most commonly diagnosed in teens and young adults.

Understanding the symptoms of IBD and knowing that anyone can be affected can help people recognize the signs early and seek the care they need. IBD can affect people differently. Young adults, pregnant women, older adults, and other groups may have specific concerns and care needs throughout their journey with the disease.

IBD Across Different Communities

Learn how Crohn’s disease and ulcerative colitis affect different communities across cultures, and life span, and experiences.

Whether you’re a parent, child, teen, or young adult, explore resources tailored to your unique experience living with Crohn’s disease or ulcerative colitis

More than 100,000 children and teens in the United States are living with inflammatory bowel disease (IBD), including Crohn's disease and ulcerative colitis. About 1 in 4 people with IBD are diagnosed before age 20, and the number of children affected continues to grow.

Early diagnosis and access to specialized care can help children manage symptoms, support healthy growth and development, and improve quality of life.

IBD & the Ashkenazi Jewish Population

Research has consistently shown that inflammatory bowel disease (IBD) is common among people of Ashkenazi Jewish ancestry than in many other populations. Studies estimate that individuals of Ashkenazi Jewish descent have a two to four-fold higher risk of developing Crohn's disease or ulcerative colitis compared with non-Jewish populations4. Researchers believe this increased risk is related to a combination of genetic, environmental, and immune system factors. However, IBD can affect people of every racial, ethnic, and cultural background, and having Ashkenazi Jewish ancestry does not mean a person will develop IBD. Ongoing research continues to improve our understanding of IBD risk while supporting earlier diagnosis and more personalized care.
