Signs and symptoms of Crohn's disease can range from mild to severe. They usually develop gradually, but sometimes will come on suddenly, without warning. You may also have periods of time when you have no signs or symptoms (remission).
The exact cause of Crohn's disease is unknown. It's thought several things could play a role, including: your genes – you're more likely to get it if a close family member has it. a problem with the immune system (the body's defence against infection) that causes it to attack the digestive system.
Most people receive a diagnosis of Crohn's disease between the ages of 15–35 years, with the average age being 29.5 years. However, some people have a silent, or asymptomatic, form of the condition, while others have it for up to 5 years before they receive a diagnosis.
It may go undiagnosed for years, because symptoms usually develop gradually and it doesn't always affect the same part of the intestine. Other diseases can have the same symptoms as Crohn's disease. But doctors can diagnose Crohn's by doing a test that looks at the inside of the intestine and doing a biopsy.
Intestinal endoscopies are the most accurate methods for diagnosing Crohn's disease and ruling out other possible conditions, such as ulcerative colitis, diverticular disease, or cancer. Intestinal endoscopies include the following: Colonoscopy.
Do You Poop a Lot With Crohn's? Some people who have Crohn's disease will go to the bathroom more often than people who don't live with a digestive disease. In severe Crohn's disease, diarrhea could occur many times a day. For some people with Crohn's disease, stools are infrequent.
Your doctor may order diagnostic testing to look for signs of Crohn's disease and rule out other possible medical conditions. Your first tests will likely include laboratory tests of your blood and stool. Further testing could include X-rays of the upper and lower GI tract.
The pain that Crohn's patients feel tends to be crampy. It often appears in the lower right abdomen but can happen anywhere along the digestive tract. “It depends on where that inflammatory process is happening,” says Nana Bernasko, DNP, gastroenterology expert with the American Gastroenterological Association.
A blood test can detect Crohn's disease but not fully diagnose it. It can only indicate if your body has inflammation and may have an IBD. With this information, your doctor can then proceed to do more tests. These other tests will make it clearer if the symptoms you're having are due to inflammatory bowel disease.
Gastroenterologists almost always recommend a colonoscopy to diagnose Crohn's disease or ulcerative colitis. This test provides live video images of the colon and rectum and enables the doctor to examine the intestinal lining for inflammation, ulcers, and other signs of IBD.
Crohn's disease can lead to serious complications, including: Abscesses: Infected pus-filled pockets form in the digestive tract or abdomen. Anal fissures: Small tears in the anus (anal fissures) can cause pain, itching and bleeding.
Individuals with so-called “silent IBD” have grossly evident intestinal inflammatory changes or complications of inflammation (eg, strictures, fistulae, abscesses) that either do not produce identifiable symptoms (including abdominal pain and bowel habit changes) and/or produce symptoms that are minimized by the ...
“Patients can have vague symptoms, such as nausea and vomiting here and there for many years,” Dr. Holmer says. “They don't know they have Crohn's disease because nobody's looking for it.
Over time, Crohn's disease can lead to other complications, including bowel obstruction, ulcers, fistulas, anal fissures, malnutrition, and other health problems. It can also increase your risk for blood clots and colon cancer. Having these symptoms doesn't automatically mean you have Crohn's.
