Colonoscopy or Sigmoidoscopy: Which Test is Right for You?
Published: Sep 12, 2024
If you’ve experienced minimal BRBPR, you might wonder about diagnostic testing options. Understanding whether a colonoscopy or sigmoidoscopy is best can help you make informed decisions.
Understanding the Tests
Colonoscopy examines the entire colon and is the gold standard for detecting lesions. It requires full bowel preparation and is often done under sedation. Sigmoidoscopy, however, only examines the lower part of the colon and can be done with minimal preparation.
When to Choose Which
Age and symptoms guide the choice between these tests. Colonoscopy is recommended for those over 50 or with risk factors. Sigmoidoscopy might be sufficient for younger patients without additional symptoms.
Pros and Cons
Colonoscopy is thorough but more demanding in terms of preparation and recovery. Sigmoidoscopy is less invasive but may miss issues in the upper colon. Weighing these factors can help you decide the appropriate approach.
