If you’re experiencing digestive issues like chronic stomach pain, acid reflux, or irregular bowel movements, your doctor may recommend an endoscopy or colonoscopy. Both are vital diagnostic tools, but they serve different purposes. At Alina Medical Centre, Nairobi’s leading gastroenterology clinic, we help patients understand which test they need—and what to expect.
Key Differences at a Glance
| Feature | Endoscopy | Colonoscopy |
|---|---|---|
| Area Examined | Upper GI (esophagus, stomach, duodenum) | Lower GI (colon, rectum) |
| Duration | 15–30 minutes | 30–60 minutes |
| Prep Required | Fasting (6+ hours) | Liquid diet + laxatives |
| Common Uses | Ulcers, gastritis, GERD | Polyps, colorectal cancer |
When Do You Need an Endoscopy?
An endoscopy (also called gastroscopy) is recommended if you have:
✔ Persistent heartburn/acid reflux (possible GERD or Barrett’s esophagus)
✔ Difficulty swallowing (strictures or tumors)
✔ Unexplained vomiting or nausea
✔ Black, tarry stools (signaling upper GI bleeding)
“Many patients ask, ‘Is endoscopy painful?’ The answer is no—you’ll be under mild sedation and feel nothing during the procedure.” — Dr. Eric Murunga, Gastroenterologist at Alina Medical Centre
When Is a Colonoscopy Necessary?
A colonoscopy is critical for:
✔ Screening for colorectal cancer (recommended starting at age 40–50)
✔ Blood in stool (hemorrhoids, polyps, or cancer)
✔ Chronic diarrhea/constipation (inflammatory bowel disease)
✔ Family history of colon cancer
Note: At Alina, we use gentle sedation so you sleep through the procedure.
Cost Comparison in Nairobi
While prices vary, here’s a general range:
- Endoscopy cost: KES 15,000–30,000
- Colonoscopy cost: KES 25,000–50,000
Why the difference? Colonoscopy requires more prep time and longer monitoring.
Which Test Is Right for You?
Your gastroenterologist will consider:
- Symptoms: Upper vs. lower GI issues.
- Age/History: Colonoscopies are routine after 40; endoscopies are symptom-driven.
- Risk Factors: Family history, smoking, or diet.
