Crohn’s Disease

« Back to Glossary Index

Crohn’s Disease is a chronic inflammatory condition that primarily affects the gastrointestinal (GI) tract, though it can involve any part of the digestive system from the mouth to the anus. It is classified under inflammatory bowel diseases (IBD), with Ulcerative Colitis being the other main type of IBD. Crohn’s Disease is named after Dr. Burrill B. Crohn, who first described the disease in 1932 along with colleagues Dr. Leon Ginzburg and Dr. Gordon D. Oppenheimer.

Causes and Risk Factors

The exact cause of Crohn’s Disease remains unknown, but it is believed to result from an interplay of genetic, environmental, and immune system factors. It occurs when the body’s immune system mistakenly attacks and destroys healthy body tissue, leading to inflammation. Risk factors include:

  • Genetics: A family history of Crohn’s increases the risk.
  • Smoking: Smoking is the most important controllable risk factor for Crohn’s Disease.
  • Environment: Living in an urban area or industrialized country may increase the risk, suggesting a role for diet or environmental factors.
  • Age: It can occur at any age, but it’s more prevalent among adolescents and young adults between the ages of 15 and 35.


Symptoms of Crohn’s Disease can range from mild to severe and may develop gradually or suddenly, including:

  • Diarrhea
  • Abdominal pain and cramping
  • Blood in the stool
  • Fatigue
  • Weight loss
  • Mouth sores
  • Reduced appetite and weight loss

Severe cases can lead to complications such as bowel obstruction, ulcers, fistulas (abnormal connections between different parts of the bowel or between the bowel and other organs), and malnutrition.


Diagnosing Crohn’s Disease involves a combination of tests and procedures since its symptoms can mimic those of other GI disorders:

  • Blood tests to check for anemia or signs of infection.
  • Stool tests to look for hidden blood in the stool.
  • Endoscopic procedures like colonoscopy or upper endoscopy to visualize the inside of the GI tract.
  • Imaging tests such as CT scans or MRI to look for evidence of Crohn’s in the intestines.


There is no cure for Crohn’s Disease, but treatments can significantly reduce its symptoms and even lead to long-term remission. Treatment options include:

  • Medication: Anti-inflammatory drugs, immune system suppressors, antibiotics, or biological therapies can be used to reduce inflammation and manage symptoms.
  • Nutrition therapy: Special diets, nutritional supplements, or feeding through a tube or IV can help ensure proper nutrition.
  • Surgery: In severe cases, surgery to remove a damaged portion of the digestive tract may be necessary.

Living with Crohn’s Disease

Living with Crohn’s Disease can be challenging due to its chronic nature and the unpredictability of flare-ups. However, with appropriate medical care, lifestyle adjustments, and support, many individuals with Crohn’s can lead active, fulfilling lives. Strategies for managing Crohn’s Disease include staying informed about the condition, adhering to prescribed treatments, maintaining a healthy lifestyle, and seeking support from healthcare professionals, support groups, or counseling if needed.

In summary, Crohn’s Disease is a complex condition with varying symptoms and degrees of severity. Its management requires a comprehensive approach involving medical treatment, nutritional support, and lifestyle adjustments to control symptoms and improve quality of life.
