Colitis vs Diverticulitis: Difference and Comparison

Inflammatory illnesses of the colon include colitis and diverticulitis. Colitis is the inflammation of the colon. Diverticulitis is the inflammation of the colon’s diverticula.

Key Takeaways

  1. Colitis involves colon inflammation, while diverticulitis occurs when small pouches in the colon (diverticula) become inflamed or infected.
  2. Colitis has several types, including ulcerative and infectious colitis, while diverticulitis is a specific condition.
  3. Treatment for colitis varies based on the cause, while diverticulitis treatment involves antibiotics, pain relief, and dietary changes.

Colitis vs Diverticulitis

Colitis is a medical condition caused by the inflammation of the inner lining of the colon, and can be caused by infection, allergic reactions or inflammatory bowel illness. Diverticulitis is a gastrointestinal condition that forms in the wall of the large intestine and inflames the diverticula.

Colitis vs Diverticulitis

Colitis is an inflammation of the colon’s inner lining. Infection, inflammatory bowel illness, ischemic colitis, allergic reactions, and tiny colitis are just some of the causes of colitis.

Diverticulitis, particularly colonic diverticulitis, is a gastrointestinal condition. It can form in the wall of the large intestine and can cause inflammation of the diverticula.

What is Colitis?

The colon, known as the large intestine, is inflamed in colitis. If you have colitis, you’ll have abdominal discomfort and pain that can range from mild to severe and arrive quickly.

Colitis does not have a nutritional treatment or cure. However, finding a balance between getting the nutrients, you need and avoiding foods that tend to aggravate your symptoms might help you manage the disease.

The colon is home to several microorganisms that coexist with the body and cause no symptoms. Shigella, Campylobacter, Ecoli, Escherichia, and Yersinia species are the most common bacteria that cause colitis.

Colitis treatment is determined by the underlying cause and is frequently centred on symptom reduction, supportive care, appropriate hydration, and pain control.

What is Diverticulitis?

Diverticulitis is a type of colitis, which is an inflammatory bowel illness. It can be serious and necessitate surgery if not treated promptly.

Diverticulitis develops when the thin necks of the diverticula get clogged with debris or indigestible foodstuff, and bacteria thrive in the blind sacs, unrestrained by the normal motor activity that maintains the intestine clean.

There is some indication that patients with diverticula, which is a precursor to acute diverticulitis, have low-grade chronic inflammation.

Digestion diverticulosis affects a large number of people in affluent Western countries. Although most people with the diverticular illness are asymptomatic, 10 to 25 percent of patients with diverticulosis develop diverticulitis.

Main Differences Between Colitis and Diverticulitis

  1. Inflammation in ulcerative colitis starts in the rectum and may spread to the colon. In contrast, the pain of diverticulitis is felt on the left side of your lower abdomen.
  2. A person’s cancer risk increases by around 0.5 percent to 1 percent every year after 8–10 years of having ulcerative colitis. Diverticulitis, on the other hand, is associated with a very low risk of cancer.
