What is Necrotizing Colitis?
Necrotizing colitis is a serious condition that happens when part of the colon loses its blood supply and the tissue begins to die. Because the colon needs oxygen-rich blood to function properly, even a short interruption in circulation can cause severe damage.
Necrotizing colitis develops when blood flow to the colon becomes blocked or greatly reduced. Several health conditions can contribute to this problem, including:
- Colon cancer
- Twisting of the bowel (volvulus)
- Hernias that trap part of the intestine
- Severe constipation or fecal impaction
- Heart disease or abnormal heart rhythms
- Hardening of the arteries (atherosclerosis)
- Diabetes
- Smoking
- Blood clotting disorders
This condition is rare, but it is considered a medical emergency. Without prompt treatment, necrotizing colitis can lead to infection, shock, or damage to other organs.
Symptoms
Symptoms of necrotizing colitis often appear suddenly and can become severe quickly. Many people need emergency medical care right away.
Common symptoms may include:
- Severe stomach or abdominal pain
- Tenderness when the abdomen is touched
- Swollen or bloated abdomen
- Nausea or vomiting
- Fever
- Rectal bleeding
- Constipation or diarrhea
- Weakness, dizziness, or fainting
- Confusion or low blood pressure in severe cases
How is it diagnosed?
Doctors begin by reviewing your symptoms and medical history and performing a physical exam. Because necrotizing colitis can become dangerous quickly, testing is usually done right away.
Diagnostic tests may include:
- Blood tests to check for infection, inflammation, or blood loss
- CT scans or abdominal X-rays to look for bowel damage or blockage
- Ultrasound imaging in some cases
- Colonoscopy to examine the inside of the colon
Sometimes the full extent of the condition is only confirmed during surgery.
How is it treated?
Necrotizing colitis usually requires emergency surgery to remove the damaged section of the colon. If possible, surgeons reconnect the healthy parts of the bowel during the same procedure.
Treatment also focuses on stabilizing the body and preventing complications. Care may include:
- IV fluids to support blood pressure and hydration
- Antibiotics to fight infection
- Intensive care monitoring
- Blood transfusions if needed
- Breathing support in severe cases
Recovery depends on how quickly treatment begins and how much of the colon is affected. Early treatment improves the chances of recovery and lowers the risk of serious complications such as sepsis or organ failure.
