Overview

An endoscopy is a procedure where a healthcare provider uses a specialized tool called an endoscope—a thin, flexible tube equipped with a light and a high-definition camera at the tip—to view the internal structures of the body on a digital monitor. Depending on the symptoms, it can examine different areas, such as the upper digestive tract (Upper GI Endoscopy) or the large bowel (Colonoscopy). Beyond viewing, doctors can pass tiny instruments through the endoscope to take tissue samples (biopsies) or perform immediate treatments.

A physician typically recommends an endoscopy if a patient experiences persistent or unexplained symptoms. You should consider discussing this procedure with your healthcare provider if you experience:

• Chronic heartburn, acid reflux, or difficulty swallowing.

• Persistent abdominal pain, nausea, vomiting, or unexplained weight loss.

• Unexplained changes in bowel habits or blood in the stool.

• A personal or family history requiring routing screenings (such as colon cancer screenings).

Proper physical preparation is vital to ensure a safe procedure and a clear field of vision for the doctor. While you must always follow your specific clinic’s instructions, standard Endoscopy Prep protocols include:

• Fasting: You must completely avoid food and liquids (remain NPO) for at least 6 to 8 hours before the procedure to ensure an empty stomach.

• Medication Adjustments: Inform your provider about all supplements and medications you take, especially blood thinners or diabetes medications, as some may need to be temporarily paused.

• Transportation arrangements: Because you will likely receive a mild sedative or anesthesia to maximize your comfort, you must arrange for a responsible adult to drive you home safely after the appointment.
