An endoscopy is a technique or a medical procedure that uses a tiny camera at the end of a long, flexible tube to visually examine your digestive tract. This treatment is used by a gastroenterologist. They diagnose and treat conditions that affect the oesophagus, stomach, and small intestine (duodenum).

You may be recommended an endoscopy exam if

You have digestive issues like nausea, vomiting, abdominal pain, swallowing difficulty, or any gastrointestinal bleeding.

The conditions like anaemia, bleeding, inflammation, diarrhoea, or cancers if detected can also require endoscopy

There are other signs one has to watch post the endoscopy like-


Chest pain

Breathless or Shortness of breath

Bloody, black or very dark coloured urine

Difficulty swallowing

Severe or continuous abdominal pain

Vomiting ( bloody vomit or coffee coloured)

One is required to get in emergency care if any of these symptoms occur post the endoscopy.


Endoscopy is one of the safest procedures carried out. Although it is a surgery and hence can have rare complications. These include-

Bleeding– If the process involves taking a piece of tissue for testing (biopsy) or treating a digestive system disease, your risk of bleeding issues is higher. This bleeding may encourage a person to go for a blood transfusion.

Infection– Endoscopies usually consist of a visual examination and a biopsy, with a low risk of infection. You are at the risk of getting infected if any other additional procedure is performed. Antibiotics can be used to treat a wide range of ailments. Your doctor may prescribe antibiotics before your surgery to avoid any infection.

Gastrointestinal tract tears– If you have a tear in your oesophagus or any section of your digestive tract, you may need to be admitted to the hospital and have surgery to repair it. This complication is extremely rare.


The process of diagnosis involves preparation before the endoscopy. These are done after you’re asked to rest on the table comfortably. The procedure will start after the person is comfortable. It involves-

Monitors or cameras will be attached to your body. It will help the doctors to keep a track of your breathing, blood pressure and heart rate.

Sedatives are given- the medicines like sedatives are given and patients are examined after the effect. It is given via the arm or forearm. You’ll feel relaxed

Anesthetic is given inside the mouth- This drug will numb your throat in preparation for the long, flexible tube to be inserted (endoscope). To keep your mouth open, you may be requested to wear a plastic mouthguard.

Endoscope insertion- you’ll be required to swallow the tube inside. The discomfort and pressure can be felt but is painless.

The noises can be made but you won’t be able to talk while the diagnosis is made.


Treatment is the procedure after knowing all your vitals are working and pre-medical conditions. You’ll be undergoing the surgery and will have the following-

Images are transmitted to a video monitor in the exam room via a tiny camera at the tip. This monitor is monitored by your doctor to check for anomalies in your upper digestive tract. If problems in your digestive tract are discovered, your doctor may take photos to examine later.

To expand your digestive tract, gentle air pressure may be supplied into your oesophagus. The endoscope may now move around freely. It also makes it easier for your doctor to observe the folds of your digestive tract. You may feel a sense of pressure or fullness as a result of the additional air.

Your doctor will use the endoscope to take a tissue sample or remove a polyp by passing special surgical equipment through it. To direct the tools, your doctor monitors the video display.

After your endoscopy, you’ll be transported to a recovery area where you can sit or rest quietly. You can rest there for an hour and the doctors will also get the chance to see any other after-effects post the endoscopy.

Following an endoscopy, you may feel some mildly unpleasant indications and symptoms at home, such as:

Bloating and gas


Sore throat

This is normal.
