FAQ Category: Flexible Sigmoidoscopy Indications

Yes. It is generally safe with very low complication rates (perforation <0.1%, bleeding <1%). Discuss risks with your doctor, especially if you have other medical conditions.

According to the CDC, screening with sigmoidoscopy every 5 years (sometimes combined with stool tests) is recommended for adults aged 50–75. High-risk patients may need earlier or more frequent testing.

Most patients undergo the procedure without sedation, though mild discomfort may occur. For anxious patients or those with severe symptoms, light sedation may be considered.

While colonoscopy examines the entire colon, flexible sigmoidoscopy is less invasive and faster. It is particularly effective for detecting rectal and sigmoid problems, but if polyps or cancer are suspected in the upper colon, colonoscopy may be required.

The most common reasons include colorectal cancer screening, rectal bleeding, chronic diarrhea, unexplained anemia, and monitoring of IBD. It’s especially valuable when symptoms are limited to the lower colon and rectum.
