What Is an Endoscopy and Why Is It Done?

Modern technology using optical fiber and ultra-fine cameras to observe the internal organs of the human body.

What Is an Endoscopy?

An endoscopy is an advanced medical test where a high-powered camera and light attached to the end of a thin, flexible tube are inserted into the body through the mouth or another natural opening to display live internal images on a monitor.

Compared to other imaging modalities or scans (such as X-rays or ultrasounds), an endoscopy allows doctors to directly view the inner lining of the esophagus, stomach, and intestines to precisely evaluate inflammation, bleeding, or depth of lesions.

Why Do Doctors Recommend an Endoscopy?

Gastritis and Ulcers

Doctors primarily prescribe this test to confirm whether chronic indigestion, heartburn (GERD), severe abdominal pain, or ulcers are present in the stomach.

Internal Bleeding

If a patient vomits blood or passes dark black stools, this test is essential for pinpointing the exact location of bleeding in the stomach or intestines.

Biopsy and Cancer Screening

If an abnormal tumor or lesion is suspected, a tissue sample (Biopsy) is collected during the endoscopy to test for cancer or bacterial infections (such as H. Pylori).

Preparation Before the Test

6 to 8 Hours Fasting

All solid foods and liquids (including water and tea) must be avoided for at least 6 to 8 hours before the test. A completely empty stomach ensures clear visibility of the digestive tract.

Special Precautions for Medications

Inform your doctor prior to testing if you take medications for diabetes, high blood pressure, or blood thinners (such as Aspirin). Some medications may need to be temporarily paused.

Throat Numbing Spray or Sedation

Just before the procedure begins, a liquid spray is applied to numb your throat. You can also request a mild sedative injection (Sedation) so you experience no discomfort or pain.

Bring a Trusted Companion

If you undergo an endoscopy with sedation, you may feel slightly drowsy afterward. For safety reasons, it is important to bring a family member or trusted friend with you.

Overcoming Fear for Easy Disease Diagnosis

Many people believe an endoscopy is an extremely painful and scary procedure. However, with modern medical advancements, it is a very brief and simple process. The main examination usually takes only 5 to 10 minutes.

With mild sedation (Short Sedation / GA), the patient remains asleep and does not feel when the procedure is completed. Patients can return home safely within 30 to 60 minutes after the procedure and resume normal activities.
