Inflammatory Bowel Disease (Crohn's and Ulcerative Colitis)
What is Inflammatory Bowel Disease (Crohn's and Ulcerative Colitis)?
Inflammatory bowel disease, or IBD, is a group of chronic conditions that cause inflammation in the digestive tract. The two main types are Crohn's disease and ulcerative colitis. Both involve an overactive immune response that damages the lining of the intestines.
Crohn's disease can affect any part of the digestive tract from mouth to anus. It often creates patchy areas of inflammation that go deep into the bowel wall. Ulcerative colitis affects only the colon and rectum. It creates continuous inflammation in the innermost lining of the large intestine.
IBD is different from irritable bowel syndrome, or IBS. IBS causes discomfort but does not damage the intestines. IBD causes real tissue damage that can lead to serious complications. Both conditions are chronic and require ongoing management to reduce inflammation and prevent flare-ups.
Symptoms
- Persistent diarrhea, often with blood or mucus
- Abdominal pain and cramping
- Urgent need to have a bowel movement
- Unintended weight loss
- Fatigue and low energy
- Reduced appetite
- Fever during flare-ups
- Anemia from blood loss
- Joint pain or skin problems
- Mouth sores
Some people experience mild symptoms for years before diagnosis. Others have severe symptoms that appear suddenly. Symptoms often come and go in cycles of flare-ups and remission.

Causes and risk factors
IBD happens when the immune system mistakenly attacks the digestive tract. Researchers believe it results from a combination of genetic factors, environmental triggers, and gut bacteria imbalances. People with a family history of IBD have a higher risk. Certain genes make some people more vulnerable to developing these conditions.
Environmental factors include smoking, which worsens Crohn's disease, and diet high in processed foods. Stress does not cause IBD but can trigger flare-ups. An imbalanced gut microbiome may also contribute to inflammation. IBD typically develops before age 30, though it can occur at any age. Living in developed countries and urban areas increases risk.
How it's diagnosed
Doctors diagnose IBD through a combination of blood tests, stool tests, and imaging studies. Colonoscopy with tissue biopsy is the gold standard for confirming IBD and determining which type. Blood tests help measure inflammation levels and check for anemia or nutritional deficiencies.
Rite Aid offers testing for inflammatory markers including arachidonic acid. This omega-6 fatty acid plays a key role in the inflammatory cascade that drives IBD. Elevated levels indicate active inflammation in the intestinal lining. Testing helps monitor disease activity and response to treatment. Talk to a healthcare provider if you have persistent digestive symptoms lasting more than a few weeks.
Treatment options
- Anti-inflammatory medications to reduce intestinal inflammation
- Immune system suppressors to calm the overactive immune response
- Biologic therapies that target specific inflammation pathways
- Antibiotics for infections or complications
- Anti-diarrheal medications and pain relievers for symptom management
- Dietary changes such as eliminating trigger foods and eating smaller meals
- Omega-3 fatty acids to help balance inflammatory omega-6 fats
- Stress management through meditation, yoga, or counseling
- Adequate sleep and regular gentle exercise
- Surgery to remove damaged portions of the intestine in severe cases

Frequently asked questions
Crohn's disease can affect any part of the digestive tract and creates patchy inflammation that goes deep into tissue layers. Ulcerative colitis only affects the colon and rectum with continuous surface inflammation. Both are types of IBD but differ in location and pattern of damage.
IBD is a chronic condition without a current cure. Treatment focuses on reducing inflammation, managing symptoms, and achieving long-term remission. Many people live full lives with proper treatment and lifestyle management. Surgery can remove damaged tissue but does not prevent the disease from returning.
Arachidonic acid is an omega-6 fatty acid that fuels inflammatory processes in the intestinal lining. High levels drive the inflammatory cascade that damages the colon in IBD. Measuring arachidonic acid helps assess disease activity and inflammation severity. Balancing it with omega-3 fats may help reduce inflammation.
Common trigger foods include high-fiber raw vegetables, spicy foods, dairy products, and fatty or fried foods. Alcohol, caffeine, and carbonated drinks can worsen symptoms. Trigger foods vary between individuals, so keeping a food diary helps identify personal patterns. Work with a dietitian to create a personalized nutrition plan.
No, they are different conditions. IBD causes physical inflammation and damage to intestinal tissue visible on scans and biopsies. IBS is a functional disorder causing digestive discomfort without tissue damage or inflammation. IBD requires medical treatment to prevent complications while IBS focuses on symptom management.
Testing frequency depends on disease severity and treatment plan. Many doctors recommend blood tests every three to six months during active disease. During remission, annual or biannual testing may be sufficient. Regular monitoring helps catch flare-ups early and adjust treatment as needed.
Stress does not cause IBD but can trigger flare-ups in people who already have the condition. The gut and brain communicate through the gut-brain axis, linking emotional stress to digestive symptoms. Managing stress through relaxation techniques, exercise, and adequate sleep helps reduce flare-up frequency.
Untreated IBD can lead to intestinal scarring, strictures, fistulas, and abscesses. Chronic inflammation increases the risk of colon cancer, especially after eight to ten years with ulcerative colitis. Malnutrition, bone loss, and anemia are common from poor nutrient absorption. Early diagnosis and consistent treatment reduce complication risk.
Diet and lifestyle changes support medical treatment but typically cannot achieve remission alone. Anti-inflammatory foods, stress management, and adequate sleep help reduce symptom severity. Some people find specific diets like low-FODMAP or Mediterranean patterns helpful. Always combine lifestyle changes with prescribed medications for best results.
IBD has a genetic component but is not directly inherited. Having a family member with IBD increases your risk by about 10 to 25 percent. Multiple genes affect susceptibility, and environmental factors also play a role. Not everyone with IBD genes develops the condition, and many people with IBD have no family history.
