Colitis

Colitis refers to the inflammation of the inner lining of the colon, which can result in discomfort, pain, and other digestive issues. This condition can arise from various causes, including infections, autoimmune reactions, or reduced blood flow to the colon. Colitis can be acute or chronic, with varying degrees of severity, and it requires prompt medical attention to manage symptoms and prevent complications.

Overview

What is Colitis?

Colitis is a broad term used to describe inflammation of the colon (large intestine). The condition can lead to a range of symptoms, including abdominal pain, diarrhea, and rectal bleeding. Colitis can be caused by infections, inflammatory bowel disease (IBD), ischemic conditions, or allergic reactions.

Types of Colitis

  • Ulcerative Colitis: A type of inflammatory bowel disease that causes chronic inflammation and ulcers in the colon and rectum.
  • Infectious Colitis: Caused by bacterial, viral, or parasitic infections.
  • Ischemic Colitis: Occurs when blood flow to part of the colon is reduced, often due to narrowed or blocked arteries.
  • Microscopic Colitis: A chronic condition where inflammation is only visible under a microscope, with two subtypes: lymphocytic and collagenous colitis.
  • Allergic Colitis: Typically seen in infants, caused by an allergic reaction to certain foods.

How Common is Colitis?

The prevalence of colitis varies depending on the type. For example, ulcerative colitis affects approximately 1 in 1,000 people in the United States, while infectious colitis is more common and often linked to foodborne illnesses. Colitis can affect people of all ages, but some forms, like ulcerative colitis, are more common in young adults.Common Symptoms

Symptoms and Causes

Common Symptoms

  • Persistent diarrhea, often with blood or pus
  • Abdominal pain and cramping
  • Urgency to have a bowel movement
  • Fatigue and weakness
  • Unintended weight loss
  • Fever (in cases of infection)
  • Dehydration

Common Causes

  • Infections: Bacterial infections (e.g., Salmonella, E. coli), viral infections (e.g., cytomegalovirus), and parasitic infections can all cause colitis.
  • Autoimmune Disorders: In conditions like ulcerative colitis, the immune system mistakenly attacks the lining of the colon.
  • Reduced Blood Flow: Ischemic colitis results from decreased blood supply to the colon, often due to narrowed arteries or blood clots.
  • Medications: Some medications, such as nonsteroidal anti-inflammatory drugs (NSAIDs) or antibiotics, can cause colitis as a side effect.
  • Food Allergies: In infants, colitis can result from an allergic reaction to proteins in milk or soy.
