When to Seek Medical Advice After Colonoscopy
Colonoscopy is a commonly performed procedure and is generally considered safe. However, as with any medical procedure, there are potential risks and side effects.
Common Side Effects After Colonoscopy:
- Mild bloating or gas
- Mild abdominal discomfort or cramping
- Small amounts of bleeding, particularly if a biopsy was taken or a polyp was removed
When to Seek Medical Attention:
- Severe or worsening abdominal pain
- Fever or chills
- Persistent vomiting
- Dizziness or fainting
- Feeling increasingly unwell after the procedure
Although uncommon, these symptoms may indicate a complication that requires medical assessment.
Colonoscopy Results & Follow-Up
Some findings may be discussed shortly after the procedure. However, if tissue samples (biopsies) are taken or polyps are removed, laboratory analysis may be required before the final results are available.
A normal colonoscopy means that no visible abnormalities were identified in the colon and rectum during the examination. Depending on your symptoms, personal risk factors, and screening history, your doctor may still recommend future screening or follow-up assessments.

Frequently Asked Questions About Colonoscopy
What do my colonoscopy results mean?
A colonoscopy may identify abnormalities such as polyps, inflammation, bleeding, or other changes within the colon and rectum. If tissue samples (biopsies) are taken or polyps are removed, they are typically sent to a laboratory for analysis. Your doctor will explain the findings and advise whether further treatment, monitoring, or follow-up colonoscopy is required.
Is colonoscopy painful?
A colonoscopy is typically performed under sedation to help ensure comfort during the procedure. While most patients do not experience significant pain, some may notice temporary bloating, cramping, or abdominal discomfort afterwards. Individual experiences can vary.
FIT or colonoscopy: which should I choose?
FIT is a stool test for hidden blood; colonoscopy directly examines the colon and may allow biopsy or polyp removal. Choice depends on age, symptoms, risk and doctor advice.
What happens if polyps are found during a colonoscopy?
Not all polyps are cancerous. If suitable, certain polyps may be removed during the colonoscopy and sent for laboratory analysis. The results help determine whether further treatment, surveillance, or follow-up colonoscopy is required.
Can polyps be removed during colonoscopy?
Yes. Certain polyps can be removed during the procedure using specialised instruments passed through the colonoscope. Removed tissue is typically sent for laboratory testing to determine whether any additional follow-up is needed.
Is there any downtime after a colonoscopy?
Most of the time, patients will only experience some temporary bloating afterwards. If the procedure involves removal of polyps, full recovery may take a week and patients should avoid strenuous activities during that period of time.
How often should I repeat colonoscopy?
The recommended interval depends on factors such as your age, family history, previous colonoscopy findings, bowel preparation quality, and overall risk profile. Your doctor will advise when a repeat colonoscopy may be appropriate.
Is colonoscopy in Singapore covered by insurance?
Yes, a colonoscopy is generally covered by private insurance, the amount depending on the policy purchased. Additionally, the procedure is also covered by Medisave for Singaporean citizens and PRs.
