An endoscopy is a medical procedure that involves the use of a flexible tube with a light and camera, known as an endoscope, to examine the interior of the body. While the idea of undergoing an endoscopy might cause apprehension, understanding what to expect can alleviate concerns and empower individuals to approach the procedure with confidence

Understanding the Endoscopy Procedure

Endoscopies are versatile procedures used to examine different parts of the body. Gastroscopy focuses on the digestive tract, bronchoscopy explores the airways, and colonoscopy examines the colon, among other variations.

Endoscopies serve dual purposes – they can be diagnostic, helping identify issues, and therapeutic, allowing healthcare professionals to perform certain interventions like biopsies  during the procedure.

Preparation Before the Procedure

A pre-procedure consultation with the healthcare provider is standard. This is an opportunity to discuss any existing medical conditions, allergies, or concerns, ensuring that the medical team is well-informed.

Fasting is often required before an endoscopy, especially for procedures involving the digestive tract. This ensures a clear view of the area being examined and reduces the risk of complications.

Certain medications, particularly blood thinners, may need to be temporarily stopped or adjusted before the procedure to minimize the risk of bleeding.

The Day of the Endoscopy

  • Arrival and Registration: Arriving at the medical facility on time is crucial. The registration process involves completing necessary paperwork and confirming details with the medical staff.
  • Pre-Procedure Assessment: Before the endoscopy, individuals undergo a pre-procedure assessment, which may include checking vital signs, reviewing medical history, and ensuring that any pre-procedure instructions were followed.
  • Discussion with the Medical Team: A final discussion with the medical team occurs before the procedure. This is the time to address any last-minute questions or concerns and to reconfirm details about the specific type of endoscopy being performed.

During the Endoscopy

Administration of Sedation

Sedation is often administered before the procedure to ensure comfort. The level of sedation varies – it could range from mild sedation where individuals remain awake and relaxed to deeper sedation where they may not recall the procedure.

Use of Numbing Agents

To enhance comfort, numbing agents may be applied, especially for procedures involving the digestive or respiratory tracts. This helps minimize any potential discomfort during the insertion of the endoscope.

Placement of the Endoscope

The endoscope is gently inserted into the relevant body opening – the mouth for gastroscopy, the nose or mouth for bronchoscopy, or the anus for colonoscopy. The flexible nature of the endoscope allows it to navigate the body’s curves.

Visualization and Examination

As the endoscope progresses through the body, the camera captures live images of the internal structures. These real-time visuals allow the healthcare team to thoroughly examine the area of focus.

Biopsy or Intervention

If abnormalities or areas of concern are identified, the medical team may perform a biopsy or intervene to address issues. Biopsies involve the removal of a small tissue sample for further examination.

Communication During the Procedure

Throughout the endoscopy, open communication between the individual and the medical team is encouraged. Any discomfort, concerns, or signals of anxiety can be addressed promptly to enhance the overall experience.

Post-Procedure Care

Recovery Period

After the endoscopy, individuals are monitored in a recovery area until the effects of sedation wear off. Vital signs are closely observed to ensure stability before discharge.

Post-Sedation Effects

It’s common to experience some drowsiness or grogginess after the procedure due to the lingering effects of sedation. Having a designated companion for transportation and support during this period is essential.

Review of Findings

Depending on the type of endoscopy and findings, healthcare providers may share preliminary results and discuss any immediate concerns. A more comprehensive review may follow in a post-procedure appointment.

Potential Post-Endoscopy Considerations

Mild Discomfort

It’s normal to experience mild discomfort after an endoscopy. This may include bloating, gas, or a sore throat, depending on the specific procedure. These effects are usually temporary and subside within a short time.

Post-Biopsy Effects

If a biopsy was performed, individuals may notice a small amount of bleeding, which is generally minimal. Persistent or heavy bleeding, though rare, should be reported to the healthcare provider.

Resuming Normal Activities

In most cases, individuals can resume normal activities within a short period after the endoscopy. However, it’s advisable to avoid strenuous activities, heavy meals, or alcohol consumption on the day of the procedure.

When to Seek Medical Attention

While complications from endoscopy are rare, it’s essential to be aware of potential signs of complications, including severe abdominal pain, persistent bleeding, or difficulty breathing. If persistent symptoms, such as severe throat pain, chest pain, or continuous nausea and vomiting, occur after the endoscopy, seeking prompt medical attention is advised.


Understanding what to expect during an endoscopy involves familiarizing oneself with the pre-procedure preparations, the dynamics of the procedure itself, and the post-procedure care. The collaborative approach between individuals and healthcare providers, coupled with open communication and adherence to guidelines, contributes to a positive endoscopy experience.
