Introduction
Have you been dealing with ongoing stomach pain, diarrhea, or fatigue? If yes, colitis might be the culprit. Colitis is a condition that affects thousands of Americans every year, yet it's often misunderstood. In this guide, we’ll break down what colitis is, its symptoms, types, causes, and the best ways to manage it — in a way that’s easy to understand and backed by reliable medical sources.
What Is Colitis?
Colitis refers to inflammation of the colon (the large intestine). It can result from infections, chronic diseases, or autoimmune disorders. The inflammation can cause discomfort and affect nutrient absorption, leading to a variety of digestive and systemic symptoms.
Common Symptoms
-
Abdominal pain and cramping
-
Frequent or urgent bowel movements
-
Diarrhea (sometimes with blood or mucus)
-
Fatigue
-
Fever
-
Unintended weight loss
If you’re experiencing any of these symptoms regularly, it’s important to consult a healthcare provider.
Types of Colitis (Comparison Table)
| Type | Cause | Chronic? | Treatment |
|---|---|---|---|
| Ulcerative Colitis | Autoimmune (IBD) | Yes | Medication, lifestyle changes, surgery |
| Crohn’s Disease | Autoimmune (IBD variant) | Yes | Biologics, immunosuppressants |
| Infectious Colitis | Bacteria, viruses, parasites | No | Antibiotics, hydration |
| Ischemic Colitis | Reduced blood flow | Sometimes | Address underlying issue |
| Microscopic Colitis | Immune-related | Yes | Anti-inflammatory meds |
Causes of Colitis
The root cause varies by type but may include:

Poor blood supply to the colon (ischemia)
-
Certain medications (NSAIDs)

Genetics and family history
