People suffering from Crohn’s often experience loss of appetite and may lose weight as a result.

Crohn's is a chronic disease, so this means patients will likely experience periods when the disease flares up and causes symptoms, followed by periods of remission when patients may not notices symptoms at all.
In more severe cases, Crohn’s can lead to tears (fissures) in the lining of the anus, which may cause pain and bleeding, especially during bowel movements. Inflammation may also cause a fistula to develop. A fistula is a tunnel that leads from one loop of intestine to another, or that connects the intestine to the bladder, vagina, or skin. This is a serious condition that requires immediate medical attention.
The symptoms you or your loved one experience may depend on which part of the GI tract is affected. Read more about the Types of Crohn's Disease and Associated Symptoms.
Crohn’s disease may affect as many as 700,000 Americans. Men and Women are equally likely to be affected, and while the disease can occur at any age, Crohn's is more prevalent among adolescents and young adults between the ages of 15 and 35.
The causes of Crohn’s Disease are not well understood. Diet and stress may aggravate Crohn’s

cause the disease on their own. Recent research suggests hereditary, genetics, and/or

The GI tract normally contains harmless bacteria, many of which aid in digestion. The immune system usually attacks and kills foreign invaders, such as bacteria, viruses, fungi, and other microorganisms. Under normal circumstances, the harmless bacteria in the intestines are protected from such an attack. In people with IBD, these bacteria are mistaken for harmful invaders and the immune system mounts a response. Cells travel out of the blood to the intestines and produce inflammation (a normal immune system response). However, the inflammation does not subside, leading to chronic inflammation, ulceration, thickening of the intestinal wall, and eventually causing patient symptoms. Crohn’s tends to run in families, so if you or a close relative have the disease, your family members have a significantly increased chance of developing Crohn’s. Studies have shown that 5% to 20% of affected individuals have a first – degree relative (parents, child, or sibling) with one of the diseases. The risk is greater with Crohn’s disease than ulcerative colitis. The risk is also substantially higher when both parents have IBD. The disease is most common among people of eastern European backgrounds, including Jews of European descent. In recent years, an increasing number of cases have been reported among African American populations.
The environment in which you live also appears to play a role. Crohn’s is more common in developed countries rather than undeveloped countries, in urban rather than rural areas, and in northern rather than southern climates.
