Colonoscopy Q&A

What is a colonoscopy?

A colonoscopy is a procedure to identify issues in the lower part of your gastrointestinal tract, specifically your large intestine, colon, and rectum.

Your Long Island Gastro provider may suggest a colonoscopy to diagnose or treat the cause of persistent symptoms like:

  • Diarrhea
  • Constipation
  • Rectal bleeding
  • Abdominal pain


A colonoscopy is also a preventive screening tool for colon cancer. Routine colonoscopies can identify changes in the colon that may indicate cancer. This type of test also allows your provider the opportunity to take a tissue sample for further evaluation to confirm or rule out colon cancer.

Your Long Island Gastro provider may recommend routine colon cancer screenings if you have a personal or family history of cancer, you’re over 50, or you have other risk factors for colon cancer.

What happens during a colonoscopy?

The team at Long Island Gastro provides sedation before a colonoscopy to keep you relaxed and comfortable. The team uses a skilled anesthesiologist to deliver the medications and monitor your vitals throughout your procedure.

You will lie on an exam table as your provider inserts a colonoscope — a thin, flexible tube with an attached light and camera that moves through your rectum and into your colon. The camera sends back real-time images of the inner part of your colon to a monitor that your doctor watches to identify gastrointestinal issues. To get a clearer picture of your colon, your provider may deliver some air in through the colonoscopy.

It can take 20-30 minutes to complete the exam, and you can expect a brief period of recovery before you can go home to rest.

What can I expect after a colonoscopy?

It’s common to have gas, bloating, or some abdominal discomfort following a colonoscopy. You will need someone to drive you home because of the anesthesia. Your Long Island Gastro physician provides comprehensive after-care instruction, which includes any activity or dietary limitations you have.

Your provider can discuss the results of your colonoscopy during a follow-up visit. If you also had a biopsy, it may take several days before the results come back from the lab.
