Colonoscopy in Los Angeles
Gentle, thorough colonoscopy with Dr. Moshe Barnajian — the most effective way to detect and prevent colon cancer, with comfortable sedation.
The Smartest Step You Can Take for Your Colon
A colonoscopy is unique in medicine: it can find and remove precancerous growths in the same visit, stopping colon cancer before it ever starts. Dr. Barnajian performs each exam with meticulous care and a focus on your comfort.
Patients are often relieved by how easy the experience is. Under gentle sedation, the exam is painless, takes about half an hour, and you head home the same day with your results explained clearly.
Whether you are due for routine screening or have symptoms that need answers, Dr. Barnajian and his Los Angeles team make it simple to get scheduled quickly.

When Should You Be Screened?
Guidelines have changed in recent years, and knowing the right timing for your situation can be life-saving.
Age 45 and Up
Average-risk adults should begin screening at 45. If the exam is normal, it is typically repeated every ten years.
Family History
A family history of colon cancer or polyps means screening should start earlier and be repeated more often.
Warning Symptoms
Rectal bleeding, a change in bowel habits, unexplained anemia, or abdominal pain deserve prompt evaluation at any age.
Preparing for Your Exam
A clear view depends on good preparation. The day before, you will follow a clear-liquid diet and take a prescribed cleansing solution that empties the colon so Dr. Barnajian can inspect the lining thoroughly. Our team walks you through every step.
Preparation has become much easier, with lower-volume options available for many patients. Because of the sedation, plan to have someone drive you home afterward.
What Happens During the Procedure
A colonoscopy is smooth and closely monitored from start to finish, and most patients are back to normal the next day.
Gentle Sedation
You are kept relaxed and comfortable, with your vital signs monitored the entire time.
High-Definition Exam
A slim, flexible scope lets Dr. Barnajian inspect the full colon in fine detail.
Polyp Removal
Any polyps are removed painlessly during the same visit, preventing them from ever becoming cancer.
Biopsies
Tissue samples can be taken from suspicious areas and analyzed to guide any further care.
Same-Day Results
After a short recovery you go home the same day and receive your findings and next steps.

What Your Visit Looks Like
From your first phone call to your results, the goal is a calm, stress-free experience. Dr. Barnajian and his team treat every patient warmly.

Colonoscopy FAQs
Is a colonoscopy painful?
No. With gentle sedation you will feel nothing during the exam and usually will not remember it. Most patients find it far easier than expected.
When should I start screening?
Average-risk adults should begin at 45. Those with a family history, symptoms, or other risk factors should start sooner. Dr. Barnajian will advise the right timing for you.
How often do I need one?
If your exam is normal and you are average risk, screening is usually repeated every ten years. If polyps are found, it may be sooner.
How long is recovery?
Most patients rest for the remainder of the day because of the sedation and return to normal activity the next day.
Do you accept insurance?
Yes. Most PPO plans are accepted and screening is often fully covered. Our team verifies your benefits in advance. Call (424) 622-9028.
