Crohn’s disease is a chronic inflammatory bowel disease (IBD) that can affect any part of the digestive tract, causing a range of symptoms and complications. If you are experiencing symptoms like persistent diarrhea, abdominal pain, weight loss, and fatigue, it’s crucial to seek help from a healthcare professional. While a primary care physician can be a starting point, effectively managing Crohn’s disease often requires the expertise of a specialist – a Crohn’s disease doctor. This article will guide you through the diagnosis and treatment process, highlighting the importance of finding the right medical expert to manage your condition and improve your quality of life.
Diagnosing Crohn’s Disease: The Role of Your Doctor
There’s no single test to definitively diagnose Crohn’s disease. Instead, a Crohn’s disease doctor, typically a gastroenterologist, will use a combination of strategies to rule out other conditions and confirm a diagnosis. This comprehensive approach is necessary because symptoms of Crohn’s can mimic other digestive disorders.
Lab Tests: Initial Steps in Diagnosis
Your Crohn’s disease doctor may start with several lab tests to get a clearer picture of your overall health and identify potential indicators of inflammation or infection.
-
Blood Tests: These are crucial in checking for anemia, a common complication of Crohn’s due to blood loss and nutrient malabsorption. Blood tests can also reveal signs of infection, inflammation levels in the body, and assess liver function. Additionally, they can screen for inactive infections like tuberculosis and evaluate your immunity against infections, which is important before starting certain Crohn’s medications.
-
Stool Studies: Analyzing a stool sample helps your Crohn’s disease doctor identify potential causes of your symptoms, such as infection-causing bacteria or parasites. Stool studies can also detect blood in the stool, a common sign of Crohn’s. Furthermore, measuring stool markers of inflammation, like calprotectin, can be a valuable tool in assessing the level of inflammation in your digestive tract.

Procedures: Visualizing and Confirming Crohn’s
To directly visualize the digestive tract and obtain tissue samples, your Crohn’s disease doctor will likely recommend one or more of the following procedures:
- Colonoscopy: This is a key procedure in diagnosing Crohn’s disease. A Crohn’s disease doctor uses a colonoscope, a flexible tube with a camera, to examine the entire colon and the terminal ileum (the end of the small intestine). During a colonoscopy, the doctor can identify inflammation, ulcers, and other abnormalities characteristic of Crohn’s. Crucially, biopsies, small tissue samples, are taken during the procedure and sent to a lab for microscopic analysis. The presence of granulomas, clusters of inflammatory cells, in these biopsies strongly suggests Crohn’s disease.

-
CT Scan: A CT scan is a specialized X-ray that provides detailed images of the bowel and surrounding tissues. A Crohn’s disease doctor may use a CT scan to assess the extent and location of inflammation, as well as to look for complications outside the bowel. CT enterography, a specific type of CT scan involving oral and intravenous contrast material, offers even clearer images of the small bowel and has become a standard imaging technique for Crohn’s.
-
MRI: MRI scans utilize magnetic fields and radio waves to create detailed images of soft tissues and organs. MR enterography, an MRI with contrast fluid, is particularly valuable for evaluating the small intestine and detecting complications like fistulas, especially around the anal area. A Crohn’s disease doctor may use MR enterography to monitor disease activity and progression, and it’s often preferred over CT enterography for younger patients due to the reduced radiation exposure.
-
Capsule Endoscopy: This less invasive procedure involves swallowing a small capsule containing a camera. As the capsule travels through the small intestine, it takes thousands of images, which are recorded and later reviewed by your Crohn’s disease doctor. Capsule endoscopy is useful for visualizing areas of the small intestine that are difficult to reach with traditional endoscopy. However, it may not always provide tissue samples for biopsy, and there’s a small risk of capsule retention, especially in patients with known strictures (narrowing) in the small bowel. Therefore, a Crohn’s disease doctor will carefully assess if capsule endoscopy is appropriate for each patient.
Treatment Strategies Guided by Your Crohn’s Disease Doctor
While there is currently no cure for Crohn’s disease, effective treatments are available to manage symptoms, reduce inflammation, and improve long-term outcomes. A Crohn’s disease doctor will develop a personalized treatment plan based on the severity and location of your Crohn’s, as well as your individual needs and preferences. The primary goals of treatment are to achieve remission, reduce flare-ups, and prevent complications.
Medications: Cornerstones of Crohn’s Disease Management
Medications are the mainstay of Crohn’s disease treatment. Your Crohn’s disease doctor will choose from a range of medications depending on your specific situation.
-
Anti-inflammatory Medicines: These are often the first line of treatment.
- Corticosteroids: Drugs like prednisone and budesonide are powerful anti-inflammatories that can quickly reduce inflammation and induce remission. However, due to potential side effects, they are typically used for short-term management of flare-ups. A Crohn’s disease doctor will carefully monitor your corticosteroid use and gradually taper the dosage as your condition improves.
- Oral 5-Aminosalicylates (5-ASAs): Medications like mesalamine and sulfasalazine can be effective for mild to moderate Crohn’s, particularly when the colon is involved. However, they may be less effective for small bowel Crohn’s.
-
Immune System Suppressors (Immunomodulators): These medications work by dampening the overactive immune response that drives inflammation in Crohn’s disease.
- Azathioprine and Mercaptopurine: These are commonly used immunomodulators for long-term management of Crohn’s. They require regular monitoring by your Crohn’s disease doctor to check for side effects like liver inflammation and increased susceptibility to infections.
- Methotrexate: This medication is sometimes used for patients who don’t respond well to other immunomodulators. Close monitoring for side effects is also necessary with methotrexate.
-
Biologics: These advanced medications target specific proteins in the immune system that contribute to inflammation.
- TNF Inhibitors (Infliximab, Adalimumab, Certolizumab pegol): These biologics block tumor necrosis factor (TNF), a key inflammatory protein.
- Ustekinumab: This biologic targets interleukins, another type of inflammatory protein.
- Vedolizumab: This medication prevents immune cells from migrating to the intestinal lining, reducing inflammation specifically in the gut.
- Risankizumab: A newer biologic that targets interleukin-23.
- Biosimilars: These are synthetic versions of original biologics, offering potentially more affordable treatment options. Your Crohn’s disease doctor can discuss if biosimilars are suitable for you.
-
Janus Kinase (JAK) Inhibitors: These newer small molecule medications, like upadacitinib, target specific enzymes involved in inflammation. They are taken orally and may be considered for Crohn’s that hasn’t responded to other treatments. However, JAK inhibitors are not recommended during pregnancy.
-
Antibiotics: While not directly treating Crohn’s inflammation, antibiotics like ciprofloxacin and metronidazole can be helpful in managing complications like fistulas and abscesses. Some research suggests they may also help reduce harmful bacteria in the gut.

Nutrition Therapy and Surgery: Additional Treatment Options
In addition to medications, your Crohn’s disease doctor may recommend other therapies.
-
Nutrition Therapy: Special diets, including enteral nutrition (liquid diet given orally or via feeding tube) or parenteral nutrition (nutrients delivered intravenously), can improve nutritional status and allow the bowel to rest, reducing inflammation. A Crohn’s disease doctor may use nutrition therapy short-term, often in combination with medications, especially before surgery or when medications are not effectively controlling symptoms. Low-residue diets may also be recommended to reduce the risk of bowel obstruction in patients with strictures.
-
Surgery: If medications and other treatments are not sufficient to control symptoms or manage complications, surgery may be necessary. A surgeon can remove damaged sections of the digestive tract and reconnect healthy portions. Surgery can also address fistulas and abscesses. It’s important to note that surgery is not a cure for Crohn’s, and recurrence is common. Therefore, a Crohn’s disease doctor will typically recommend post-surgery medication to minimize the risk of relapse.
Lifestyle Adjustments and Coping Strategies
Managing Crohn’s disease effectively involves not only medical treatment but also lifestyle modifications and coping strategies. Your Crohn’s disease doctor and other healthcare professionals can provide guidance in these areas.
-
Dietary Changes: While diet doesn’t cause Crohn’s, certain foods can trigger or worsen symptoms. Keeping a food diary can help identify trigger foods. General dietary recommendations include limiting dairy, eating smaller meals, staying hydrated, and considering multivitamins. Consulting a registered dietitian can be beneficial, especially if you are experiencing weight loss or dietary restrictions.
-
Smoking Cessation: Smoking worsens Crohn’s disease, increasing the risk of flare-ups, medication needs, and surgery. Quitting smoking is crucial for improving digestive health and overall well-being.
-
Stress Management: Stress can exacerbate Crohn’s symptoms. Techniques like exercise, biofeedback, relaxation exercises, and meditation can help manage stress levels and potentially reduce flare-ups.
-
Coping and Support: Living with Crohn’s disease can be emotionally challenging. Being well-informed about the condition, joining support groups, and talking to a therapist can provide emotional support and practical advice for managing the challenges of Crohn’s.
