This condition involves an abnormal immune response that causes excess inflammation. It most often affects the intestinal walls, particularly in the lower part of the small intestine (<a class="image-modal" data-alt="The small intestine connects the stomach and the colon.

However, inflammation can occur in any part of the digestive system, from the mouth to the anus. The inflamed tissues become <a class="image-modal" data-alt="Diagram showing healthy colon compared with abnormalities in Crohn disease and ulcerative colitis. In Crohn disease the abnormalities include fat wrapping, fissures, a cobblestone appearance, and muscle hypertrophy, while ulceration within the mucosa occurs in ulcerative colitis." data-caption="" data-credit="Alila Medical Media/Shutterstock.com" data-filepath="images/PX00019K_PRESENTATION.jpeg" data-imgtype="genetics" data-pix="PX00019K" data-sourceurl="" data-title="Intestinal abnormalities in Crohn disease and ulcerative colitis" href="https://medlineplus.gov/images/PX00019K_PRESENTATION.jpeg" id="PX00019K_4" title="Show image">thick and swollen<img alt="" class="image-modal-icon" src="https://medlineplus.gov/css/img/icon_camera_small.png"/></a>, and the inner surfaces of the digestive system may develop open sores (ulcers).</p><p>Crohn's disease most commonly appears in a person's late teens or twenties, although the disease can begin at any age. Signs and symptoms tend to flare up multiple times throughout life. The most common features of this condition are persistent diarrhea, abdominal pain and cramping, loss of appetite, weight loss, and fever. Some people with Crohn's disease have blood in the stool from inflamed tissues in the intestine; over time, chronic bleeding can lead to a low number of red blood cells (<a class="image-modal" data-alt="Diagram of blood cells, showing one sample with normal blood and another with a smaller number of red blood cells, indicating anemia" data-caption="" data-credit="Designua/Shutterstock.com" data-filepath="images/PX0001AS_PRESENTATION.jpeg" data-imgtype="genetics" data-pix="PX0001AS" data-sourceurl="" data-title="Anemia" href="https://medlineplus.gov/images/PX0001AS_PRESENTATION.jpeg" id="PX0001AS_5" title="Show image">anemia<img alt="" class="image-modal-icon" src="https://medlineplus.gov/css/img/icon_camera_small.png"/></a>). In some cases, Crohn's disease can also cause inflammation affecting the joints, eyes, or skin.</p><p>Intestinal blockage is a common complication of Crohn's disease. Blockages are caused by swelling or a buildup of scar tissue in the intestinal walls. Some affected individuals also develop fistulae, which are abnormal connections between the intestine and other tissues. Fistulae occur when ulcers break through the intestinal wall and passages form between loops of the intestine or between the intestine and nearby structures (such as the bladder, vagina, or skin).</p><p>Crohn's disease is one common form of inflammatory bowel disease (IBD). Another type of IBD, <a data-pid="15967" href="https://medlineplus.gov/genetics/condition/ulcerative-colitis/">ulcerative colitis</a>, also causes chronic inflammation of the intestinal lining. Unlike Crohn's disease, which can affect any part of the digestive system, ulcerative colitis typically causes inflammation only in the colon.</p></div>

<h2>Frequency</h2>
|
||
|
||
<section><div class="mp-content"><p>Crohn's disease is most common in western Europe and North America, where it has a prevalence of 100 to 300 per 100,000 people. More than half a million Americans are currently affected by this disorder. Crohn's disease occurs more often in people of northern European ancestry and those of eastern and central European (Ashkenazi) Jewish descent than among people of other ethnic backgrounds. For reasons that are not clear, the prevalence of Crohn's disease has been increasing in the United States and some other parts of the world.</p></div>

<h2>Causes</h2>
|
||
|
||
<section><div class="mp-content"><p>The causes of Crohn's disease are complex. This condition results from a combination of genetic, environmental, and lifestyle factors, many of which are unknown.</p><p>Many of the major genes related to Crohn's disease, including <em><a data-pid="17615" href="https://medlineplus.gov/genetics/gene/nod2/">NOD2</a></em>, <em><a data-pid="17759" href="https://medlineplus.gov/genetics/gene/atg16l1/">ATG16L1</a></em>, <em><a data-pid="17761" href="https://medlineplus.gov/genetics/gene/il23r/">IL23R</a></em>, and <em><a data-pid="17763" href="https://medlineplus.gov/genetics/gene/irgm/">IRGM</a></em>, are involved in immune system function. The proteins produced from these genes help the immune system sense and respond appropriately to bacteria in the lining of the digestive tract. Many of the proteins play roles in autophagy, which is a process that cells use to surround and destroy bacteria and viruses. Variations in these genes may disrupt autophagy or otherwise alter the immune system's response to bacteria in the digestive system. In combination with other genetic and environmental factors, these changes can lead to chronic inflammation and result in the digestive problems characteristic of Crohn's disease.</p><p>Researchers have identified at least 200 genetic variations that influence Crohn's disease risk. The majority of these variations are thought to act by subtly changing the amount, timing, and location of gene activity (expression). The mechanism by which many of the variations influence disease risk is unknown, although they probably alter immune system function in some way. Considered together, the known genetic variations account for only a small percentage of the total Crohn's disease risk that is due to genetic factors.</p><p>Environmental and lifestyle factors likely have a large impact on Crohn's disease risk. Studies have found that cigarette smoking doubles the likelihood of developing this disease, and it may also play a role in periodic flare-ups of signs and symptoms. Crohn's disease is more prevalent in urbanized societies, suggesting that factors related to increased industrialization and sanitation also play a role. Additionally, certain aspects of a person's diet, including sugar, fats, and fiber, have been proposed to influence Crohn's disease risk. Many of the potential lifestyle and environmental risk factors are probably related, directly or indirectly, to abnormal inflammation. However, the exact relationship between these factors and Crohn's disease risk remains unclear.</p></div>
