Crohn’s disease is one of a group of diseases known as inflammatory bowel diseases.
It is a chronic condition of your gastrointestinal (GI) tract, your esophagus, stomach,
and gut. Over time Crohn’s can damage parts of the GI tract. Although it commonly
affects the end of small intestine (ileum) and the beginning of the large intestine
(colon), it may be found anywhere in the GI tract.
Your risk of getting Crohn’s disease may be tied to your family or to your environment.
Learn about the risks you may have for Crohn’s disease by taking this assessment.
Note: A risk factor is anything that affects your chance of getting a disease. Having
a risk factor, or even several risk factors, doesn’t mean that you will get the disease.
And some people who get the disease may not have had any known risk factors.
You told us that you are years
old. Crohn’s disease happens most often in people who are ages 15 to 40. Although
Crohn’s disease happens more often in this age group, it may happen at any age.
You told us you have a parent, sibling, or child (first-degree
relative) with Crohn’s disease. Crohn’s tends to run in families because the
condition has a genetic component. People with brothers, sisters, parents, or
children with Crohn’s disease have a higher risk of developing the disease than
other people. Family history of the condition is the biggest risk factor for
developing it. Children of parents with Crohn’s disease tend to develop Crohn’s at
an earlier age than other people. Remember to share your family history with your
You told us you have a grandparent, uncle, aunt, nephew, niece,
half-brother, or half-sister (second-degree relative) with Crohn’s disease. Crohn’s
tends to run in families because the condition has a genetic component. People with
a second-degree relative with Crohn’s are at higher risk for developing the disease.
Family history of the condition in second-degree relatives is the second biggest
risk for developing it. Remember to share your family history with your healthcare
You told us that you are of Eastern European Jewish (Ashkenazi)
decent. According to one research study, people with this ethnic background are
about 4 times more likely to develop inflammatory bowel disease. This includes
ulcerative colitis and Crohn’s disease. Remember to share your family history with
your healthcare provider.
You don’t have a first- or second-degree relative with Crohn’s
disease and you aren’t of eastern European Jewish ancestry. Many older studies
showed that Crohn’s disease occurs more often in Caucasians than in other racial or
ethnic groups. But more recent studies show that this may no longer be true. For
example, in some areas of the U.S. the rate of Crohn’s in African Americans is
nearing that of Caucasians. Crohn’s disease is less common in Asian Americans,
Hispanic Americans, and American Indians, compared with Caucasians. These
differences may be tied to environmental factors instead of to ethnic or racial
backgrounds. Some of these environmental factors are discussed elsewhere in these
You told us that you are a smoker. Smoking makes it roughly twice
as likely that you’ll get Crohn’s disease. Smoking also makes Crohn’s symptoms
worse. In particular, flare-ups are more common and more severe. Smoking also may
make Crohn’s come back after surgery. Former smokers are also at risk for Crohn’s,
but the risk is lower. Talk with your healthcare provider about programs that can
help you quit.
You told us that you have been a smoker. Research shows smoking
makes it more likely that you’ll get Crohn’s disease. Smoking also makes Crohn’s
symptoms worse. In particular, flare-ups are more common and more severe. Smoking
also may make Crohn’s come back after surgery. Former smokers are also at risk for
Crohn’s, but the risk is lower.
You told us you don’t smoke and haven’t smoked in the past.
Smoking makes it roughly twice as likely that you’ll get Crohn’s disease. By not
smoking you have cut your risk of developing Crohn’s.
You told us you had your appendix removed (appendectomy) .
Research shows there may be a connection between having your appendix removed and
development of Crohn’s disease, but the connection is not clear. In the months right
after an appendectomy, the risk for Crohn’s is higher. It then gets lowers over
time. Researchers think this may be because the symptoms of Crohn’s and appendicitis
are so similar. This makes it hard to diagnose Crohn’s at firstA health provider may
remove an appendix to relieve symptoms that were really caused by Crohn’s. Remember
to tell your healthcare provider about any surgeries and procedures you’ve had.
The environment you live in may also play a role. Crohn’s disease
seems to be more common in developed countries than in undeveloped countries. It is
also more common in cities and industrial areas instead in rural areas. It’s also
more common in northern countries than southern countries in the Northern
Hemisphere. Researchers aren’t sure why this is so. They think these variations in
location may be because of a ‘Western’ lifestyle. People who live a Western
lifestyle eat more meat and are exposed to more pollution and more industrial
Crohn’s disease has no cure. But several treatments are available
that can ease and control symptoms of the condition. The goal of treatment is to
bring the disease into remission. This can allow a person with Crohn’s to lead a
People with Crohn’s are at risk for early small bowel and
colorectal cancer. If you have Crohn’s, talk with your healthcare provider about
getting checked for these cancers.
