18 September, 2025

Has your doctor recommended an endoscopy procedure? Of course, before you embark on a medical procedure, you want to know everything about it. We understand your desire. Having familiarized yourself with what lies ahead, you will be able to prepare well (including mentally) and feel as confident as possible! Endoscopy is a safe, standard, and highly effective procedure. Doctors use it to diagnose and treat diseases of the digestive system. In this guide, we provide a detailed and accessible explanation of the features of endoscopy. You will learn how to prepare for it and what to expect at each stage.

What Is an Endoscopy Treatment?

It is a non-surgical procedure in which the doctor uses a thin, flexible tube with a light source and a camera (endoscope) to examine the inside of the upper digestive tract. It allows doctors to carefully examine the esophagus, stomach, and the first part of the small intestine (duodenum).

Doctors may recommend an endoscopy to:

  • Check for chronic heartburn, GERD, or abdominal pain.
  • Diagnose swallowing difficulties
  • Identify sources of internal bleeding.
  • Perform biopsies or remove foreign bodies.
  • Monitor ongoing gastrointestinal diseases.

Endoscopy enables the accurate identification of the patient’s problems. As a result, the doctor can prescribe effective treatment. Please do not delay your visit to a specialist.

Types of Endoscopy

Let’s examine the most common types of this procedure.

Upper Gastrointestinal Endoscopy

The most common type is when the doctor performs this procedure under light sedation. The specialist inserts the endoscope through the mouth. The examination usually takes 10-20 minutes.

Capsule Endoscopy

The patient swallows a small capsule with a camera. The camera takes pictures as it passes through the digestive tract. This is especially useful for areas inaccessible to a standard endoscope.

How to Prepare for an Endoscopy?

Proper preparation is the key to getting safe and accurate results. Therefore, take your preparation for the procedure very seriously.

  • Do not eat or drink anything for 4-8 hours before the procedure.
  • Discontinue taking any medications or supplements that your doctor has recommended.
  • Have someone drive you home if your doctor will use sedation.
  • Tell your doctor if you have any medical conditions, such as diabetes or bleeding disorders, or if you are taking blood thinners.

You will receive detailed instructions in advance. Be sure to read them carefully. and follow all of your doctor’s recommendations. Of course, you should choose a specialist you trust. At our clinic, we utilize the most advanced medical technologies and employ an individualized approach tailored to each patient. We will carefully review your medical history and select the most suitable option.

What Happens during the Procedure

The patient changes into a medical gown. The doctor administers a sedative through an intravenous catheter. Sometimes the specialist sprays a numbing spray on the throat. The doctor carefully inserts the endoscope through the patient’s mouth and through the gastrointestinal tract. The images appear on the monitor in real time. During the examination, the specialist can also perform a biopsy or minor treatment, if necessary.

While the endoscope is moving down the esophagus, you cannot speak at this time, but you can make sounds. The device does not interfere with breathing, so there is no reason to worry.

At the end of the endoscope is a miniature camera that transmits a clear image to the video monitor. The doctor carefully watches the screen to detect possible changes or abnormalities in the upper digestive tract. If necessary, the doctor takes photographs for later analysis.

A small amount of air may be supplied to the esophagus. This helps straighten the walls and makes it easier to examine the folds. The patient may feel slight pressure or a feeling of fullness, which is normal. All actions are controlled with high accuracy via a video monitor.

After the examination is completed, the endoscope is carefully removed through the mouth. On average, the procedure takes 15-30 minutes and is quick and safe. Most patients do not complain of pain, so there is no need to worry. However, after the procedure, you may experience slight discomfort in the throat that will not last long.

Recovery Time after Endoscopy

After the procedure, you will be taken to a recovery room where you can sit or lie down quietly. This usually takes about an hour. Your medical team will monitor you as the sedative wears off.

When you return home, you may experience mild discomfort:

  • bloating or gas,
  • mild cramping,
  • discomfort or sore throat.

These symptoms typically resolve on their own within a short period. However, if they become more severe or cause concern, please contact your doctor. Spend the rest of the day relaxing. Even if you feel alert and energetic, sedatives can slow down your reactions and impact your decision-making. Therefore, it is best to postpone active activities and give your body time to recover.

Abstain from driving, drinking alcohol, and making important decisions for 24 hours after sedation. Your doctor may provide preliminary results right away. Please note that biopsy results are typically provided later. Most patients return to their normal activities the same day or the next morning.

Is Endoscopy Safe?

Yes, endoscopy is widely accepted and completely safe. Complications such as bleeding, infection, or perforation of the gastrointestinal tract are rare. Your doctor will assess your risks and answer your questions before the procedure.
