Risk factors for Crohn's disease may include:
Aug. 13, 2014
- Age. Crohn's disease can occur at any age, but you're likely to develop the condition when you're young. Most people who develop Crohn's disease are diagnosed before they're 30 years old.
- Ethnicity. Although Crohn's disease can affect any ethnic group, whites and people of Eastern European (Ashkenazi) Jewish descent have the highest risk.
- Family history. You're at higher risk if you have a close relative, such as a parent, sibling or child, with the disease. As many as 1 in 5 people with Crohn's disease has a family member with the disease.
- Cigarette smoking. Cigarette smoking is the most important controllable risk factor for developing Crohn's disease. Smoking also leads to more severe disease and a greater risk of having surgery. If you smoke, it's important to stop.
- Nonsteroidal anti-inflammatory medications. These include ibuprofen (Advil, Motrin IB, others), naproxen sodium (Aleve, Anaprox), diclofenac sodium (Voltaren, Solaraze) and others. While they do not cause Crohn's disease, they can lead to inflammation of the bowel that makes Crohn's disease worse.
- Where you live. If you live in an urban area or in an industrialized country, you're more likely to develop Crohn's disease. This suggests that environmental factors, including a diet high in fat or refined foods, play a role in Crohn's disease. People living in northern climates also seem to be at greater risk.
