What is Crohn’s Disease?

Crohn’s Disease is a chronic Inflammatory Bowel Disease (IBD) that causes inflammation of the digestive tract. Unlike Ulcerative Colitis, it’s not isolated to one area, it can affect any part of the GI tract from the mouth to the anus. However, it typically affects the small intestine and colon. 

Crohn’s Disease mostly affects adolescents and young adults, ages 15 to 35. An estimated 3 million people in the U.S. are affected by Crohn’s Disease, which equals about 50% of inflammatory bowel disease (IBD) cases. 

Causes of Crohn’s Disease

The exact cause of Crohn’s Disease isn’t well known, but many doctors believe it has a lot to do with family history and environmental factors. Things such as your diet and stress can aggravate or trigger Crohn’s Disease, but never cause it in the first place. 

According to the Crohn’s & Colitis Foundation of America, 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. 

Bacteria that aid in digestion, which are harmless to your body, reside in your GI tract. Normally, your immune system doesn’t bother these bacteria, but for people with IBD and Crohn’s Disease, the immune system creates inflammation in the areas where those bacteria reside as a natural response. 

Symptoms of Crohn’s Disease

Symptoms specific to GI tract inflammation include: 

  • Abdominal cramps 
  • Urgent bowel movements 
  • Persistent diarrhea 
  • Rectal bleeding 

 

Other symptoms of Crohn’s Disease and most IBD conditions: 

  • Fever 
  • Fatigue 
  • Weight loss 
  • Loss of appetite 
  • Night sweats 

 

Sometimes, people with Crohn’s Disease may not experience many symptoms, but they can be triggered by specific foods. While digestive issues can be a symptom of numerous GI problems, talk to your doctor if specific foods give you these symptoms, as it may be a sign of Crohn’s Disease. 

Treatment for Crohn’s Disease

Medication

This is the primary form of immediate treatment for Crohn’s Disease. Medication won’t cure Crohn’s Disease, but the goal is to suppress it. As symptoms are suppressed, it allows time for your GI tract tissue to heal properly from any damage done to the lining which ultimately will increase the time between flare-ups.

Nutrition

An easy way to control flare-ups and triggers is to change your diet and nutritional intake. You will be advised on what foods to avoid and what to eat.

Surgery

Surgery is only necessary if medicine and diet changes can’t control flare-ups. However, nearly 70% of people with Crohn’s Disease end up needing surgery at some point in their life. This is because Crohn’s Disease can lead to the creation of a fissure, fistula, or some intestinal obstruction. A portion of the affected area may also need to be removed, which is called a resection.

Frequently Asked Questions

Common trigger foods include high-fiber vegetables, dairy products, spicy foods, and fatty or fried items. A low-residue diet may help reduce symptoms during flare-ups.
Crohn’s Disease is diagnosed through a combination of blood tests, stool tests, colonoscopy, and imaging studies such as CT scans or MRIs to evaluate inflammation and rule out other conditions.
Crohn’s Disease is a lifelong condition with no cure. However, symptoms can be managed effectively through medication, lifestyle changes, and sometimes surgery to maintain remission and reduce flare-ups.
While stress doesn’t cause Crohn’s Disease, it can exacerbate symptoms or trigger flare-ups. Stress management techniques like meditation and exercise can help alleviate these effects.
Treatment options include anti-inflammatory drugs, immune system suppressors, biologics, antibiotics, and surgery. Your doctor may also recommend dietary adjustments and nutritional supplements.
Common signs of Crohn’s Disease include abdominal pain, chronic diarrhea, loss of appetite and weight loss, bloody stool (rectal bleeding), mouth ulcers or pain in your mouth or gums, fever & fatigue, and abscesses of infections around your anal canal.

Crohn’s Disease can also cause symptoms in body parts outside of your digestive tract, including joint pain, rashes, eye inflammation, kidney stones, osteoporosis, skin tags (usually around the anus), and inflammation in bile ducts.
Crohn’s Disease can cause complications that may require more treatment or surgery, such as Abscesses, Anal fissures, Fistulas, Bowel obstructions, Malnutrition, and Anemia.
Risk factors include age (late teens through early 30s), family history, smoking, stress, and appendectomy.
