A risk factor is something that increases your likelihood of getting a disease or condition.
It is possible to develop inflammatory bowel disease with or without the risk factors listed below. However, the more risk factors you have, the greater your likelihood of developing inflammatory bowel disease. If you have a number of risk factors, ask your doctor what you can do to reduce your risk.
While scientists continue to search for the cause of inflammatory bowel disease, they have determined that certain genetic and environmental factors may increase the likelihood of developing the condition. Exactly why these factors add to the risk is not known at this time.
Risk factors include the following:
Having a family member with inflammatory bowel disease increases your chances of getting the disease.
White people are more likely to develop both types of inflammatory bowel disease. People of Jewish heritage are at greater risk of Crohn’s disease.
Smoking adds to the risk for Crohn’s disease but seems to lower the risk of ulcerative colitis. In addition, former smokers are at greater risk than nonsmokers.
Inflammatory bowel disease seems to occur more often among people in higher socioeconomic classes and people with white-collar jobs.
