Crohn’s disease is inflammation of any part of the digestive tract. It is often found in the intestines where the small intestine and the colon meet, causing pain and discomfort.
While the exact cause of Crohn’s disease is unknown, this autoimmune disorder is linked to a problem with the body’s immune system response. Instead of protecting the body, the immune system’s overactive response causes chronic inflammation.
Risk Factors
Crohn’s disease may occur at any age, but typically affects people between ages 15 to 35 – especially those with these risk factors:
A stool culture may be done to rule out other possible causes of symptoms
Treatment
There is no cure for Crohn’s disease, but treatment can help control symptoms and reduce flare-ups. Many patients find relief through a combination of lifestyle changes, medication, and medical care.
Diet and lifestyle changes may include:
Eating a balanced diet with smaller meals throughout the day
Drinking water in small amounts throughout the day
Avoiding high-fiber foods such as bran, beans, nuts, seeds, and popcorn
Limiting fatty, greasy, or gas-producing foods
Managing stress through healthy coping strategies
Medications may also help manage symptoms:
Over-the-counter options like loperamide for diarrhea and pain relievers for discomfort
Fiber supplements in some cases
Prescription medications, including:
Aminosalicylates (5-ASAs) to manage mild to moderate symptoms
Corticosteroids like prednisone for moderate to severe Crohn’s disease
Immunosuppressive medications such as azathioprine or 6-mercaptopurine
Antibiotics for abscesses or fistulas
If medications do not provide relief, surgery may be recommended. A bowel resection removes damaged or diseased sections of the intestine or drains an abscess. Surgery can reduce symptoms but does not cure Crohn’s disease.
Complications
It's possible for patient of Crohn's disease to develop one or more of the following complications:
Anal fissure: A small tear in the tissue around the anus, often causing painful bowel movements and potentially leading to a perianal fistula.
Arthritis: A potential health issue associated with Crohn's disease.
Bowel obstruction: Occurs when the normal flow in the intestines gets blocked.
Blood clots: Crohn's increases the risk of blood clots in veins and arteries.
Colon cancer: If Crohn's disease affects your colon, your risk of colon cancer increases.
Fistulas: Abnormal connections between different body parts, often occurring near or around the anal area (perianal).
Gallbladder: Crohn's disease may impact the gallbladder.
Liver disease: Crohn's disease may also affect the liver.
Low iron (anemia): A potential consequence of Crohn's.
Malnutrition: Difficulty in eating or absorbing enough nutrients due to diarrhea, abdominal pain, and cramping.
Medication risks: Certain drugs used to treat Crohn's, which block immune system functions, are associated with a small risk of developing cancers like lymphoma and skin cancers, as well as an increased risk of infections.
Skin disorders: Hidradenitis suppurativa is a condition that many people with Crohn's may develop.
Ulcers: Sores that can develop on the inner lining of the digestive tract.
When to See a Doctor
You should contact a doctor if you notice ongoing changes in bowel habits or symptoms linked to Crohn’s disease. Early care can help prevent complications and improve symptom control.
Seek medical attention if you experience:
Persistent abdominal pain
Blood in your stool
Nausea or vomiting
Diarrhea lasting longer than two weeks
Unexplained weight loss
Fever along with digestive symptoms
Prompt evaluation can lead to earlier diagnosis and more effective treatment.
While Crohn’s disease cannot be prevented, certain habits may help reduce flare-ups and support overall digestive health.
Diet
Some foods can worsen symptoms during flare-ups. Keeping a food diary may help identify triggers.
Helpful dietary tips include:
Taking multivitamins if nutrient absorption is an issue, with doctor approval
Eating five or six smaller meals each day
Limiting or avoiding dairy if it worsens symptoms
Drinking plenty of water and avoiding alcohol and caffeine
Working with a registered dietitian if weight loss or food restrictions occur
Smoking
Smoking increases the risk of developing Crohn’s disease and can worsen symptoms. Quitting smoking can improve digestive health and overall well-being.
Stress
Stress does not cause Crohn’s disease, but it can trigger flare-ups.
Ways to manage stress include:
Biofeedback to promote relaxation
Light to moderate exercise to support digestion and mental health
Relaxation techniques such as deep breathing, yoga, or meditation
Managing stress and maintaining healthy habits can play an important role in long-term symptom control.
What is Crohn’s disease?
Crohn’s disease is a long-term inflammatory bowel disease. It causes swelling and irritation in the digestive tract. Common symptoms include stomach pain, diarrhea, fatigue, weight loss, and anemia. There is no cure, but treatments can help control symptoms and slow progression.
Is Crohn’s disease contagious?
No. Crohn’s disease cannot be spread from person to person.
Is Crohn’s disease genetic?
It can run in families. About 15 percent of people with Crohn’s have a close family member with the condition, but genetics alone do not explain every case.
Is Crohn’s disease an autoimmune disease?
Some experts believe it involves the immune system attacking the digestive tract, but it is not officially labeled as autoimmune. Research is still ongoing.
Causes and Risk Factors
How do you get Crohn’s disease?
The exact cause is unknown. It is likely linked to genetics and an immune system that does not work properly. Diet and stress do not cause Crohn’s, but they can worsen symptoms.
Who is at risk for Crohn’s disease?
Risk factors include:
Being under age 30 at diagnosis
Family history of Crohn’s disease
Smoking cigarettes
Regular use of certain pain relievers like ibuprofen or naproxen
Being white or of Eastern European Jewish descent
Symptoms and What It Feels Like
What does Crohn’s disease feel like?
Symptoms depend on where inflammation occurs. Common symptoms include:
Abdominal pain or cramping
Diarrhea
Fatigue
Weight loss
Nausea or vomiting
Bloating and gas
Pain can range from mild to severe and may affect the abdomen, joints, or rectal area.
What does Crohn’s disease poop look like?
Stool may appear loose, watery, hard, bloody, oddly colored, or coated with mucus. Mucus is common during flare-ups and is usually not dangerous.
What are Crohn’s disease symptoms in women?
Women may have worse symptoms during menstruation. Some experience anemia, bone loss, fertility issues, or sexual discomfort in addition to digestive symptoms.
Diagnosis and Testing
How is Crohn’s disease diagnosed?
Doctors use a combination of tests to confirm Crohn’s and rule out other conditions. These may include:
Colonoscopy or sigmoidoscopy
Endoscopy or capsule endoscopy
CT or MRI scans
Upper GI series or barium enema
Stool tests
Treatment and Surgery
Can Crohn’s disease be cured with surgery?
No. Surgery is not a cure. It removes damaged sections of the digestive tract and can fix complications like fistulas or abscesses. Symptoms often return later, usually near the repaired area. Medication after surgery helps reduce flare-ups.
Is Crohn’s disease fatal?
If untreated, serious complications can occur and may be life-threatening. With proper medical care, most people live full lives without severe complications.
Life Expectancy and Disability
What is life expectancy with Crohn’s disease?
Most people with Crohn’s have a near-normal life expectancy when the disease is well managed.
Is Crohn’s disease a disability?
Yes. Crohn’s disease qualifies as a disability under Social Security rules if medical records show severe limitations.
Diet and Nutrition
What should you not eat with Crohn’s disease?
Many people are advised to limit or avoid:
Alcohol
Fatty or fried foods
Butter, oils, and creamy sauces
Carbonated drinks
Coffee, tea, and chocolate
Corn
High fiber foods
Dairy if lactose intolerant
What can you eat with Crohn’s disease?
Diet varies by person. Commonly tolerated foods include:
Low fiber foods
Cooked vegetables like carrots
Potatoes
Yogurt
Oily fish
Cereals
Soft fruits and vegetables
A gastroenterologist can help create a personalized plan.
