What is a Gastroscopy?

Gastroscopy ( commonly referred as gastro-esophago-duodenoscopy, OGD) is a medical test where a doctor puts a long, flexible tube with a camera and light on the end down your esophagus. With this, it can look inside your stomach and intestines. It helps the doctor to see if there are any problems, such as ulcers, inflammation, tumors, or bleeding. The procedure is usually done under local anesthesia and takes around 15 to 30 minutes.

Why would I need a Gastroscopy?

A gastroscopy may be recommended if you have symptoms such as persistent heartburn, difficulty swallowing, abdominal pain, vomiting, or unexplained weight loss. It can also be used to diagnose and treat various conditions of the upper digestive tract, such as ulcers, inflammation, and certain types of cancer.

How should I prepare for a Gastroscopy?

Your doctor will provide you with specific instructions, but typically you will be asked to refrain from eating or drinking anything for a few hours before the procedure. Additionally, you may be required to discontinue certain medications such as blood thinner. Your doctor may also administer a sedative to help you remain calm and relaxed during the procedure.

Is Gastroscopy painful?

You may feel some discomfort or pressure during the procedure, but it is usually not painful. You doctor will give local anesthetic to numb your throat, and a sedative to help you relax. After the procedure, you may have a sore throat or bloating, but these symptoms should go away within a few hours.

Are there any risks associated with Gastroscopy?

Gastroscopy is generally a safe procedure, but like any medical procedure, there is a small risk of complications. The most common risks associated with gastroscopy include bleeding, infection, or a tear or hole in the digestive tract (perforation). However, these complications are very rare and occur in less than 1% of cases. Your doctor will discuss the risks and benefits of the procedure with you beforehand and take measures to minimize any potential risks.

Are there any alternative to Gastroscopy?

The alternative of gastroscopy depends on the specific medical situation and symptoms being evaluated. Here are some alternative diagnostic procedures that may be recommended instead of gastroscopy:

  1. Water soluble contrast study: This is a diagnostic imaging test where the patient swallows a liquid containing contrast, which coats the esophagus, stomach, and small intestine. Radiographer will  take X-ray images to evaluate the anatomy and function of these organs.
  2. CT scan or MRI scan: These are imaging tests that use X-rays or magnets to create detailed images of the internal organs. This can be helpful to diagnose certain conditions, such as tumors or inflammation, in the upper digestive tract.

  3. Capsule endoscopy: This is a diagnostic test where the patient swallows a small camera in the form of a pill, which takes pictures as it travels through the digestive tract. It may be used to diagnose conditions such as small bowel tumors or bleeding.

It’s important to note that these diagnostic procedures are not always alternatives to gastroscopy, but rather complementary tests that may be used in addition to or instead of gastroscopy depending on the specific medical situation. Your doctor will evaluate your symptoms and medical history to determine the most appropriate diagnostic test for you.

How frequent do I need a Gastroscopy?

In general, there is no specific frequency for gastroscopy. It depends on your individual medical history, symptoms, and any underlying conditions you may have. Gastroscopy is not a routine test for the general population. However, it may be recommended for certain individuals who have risk factors or symptoms of digestive tract disorders. Your doctor will evaluate your situation and recommend gastroscopy as necessary to monitor or treat any medical conditions you may have. It is important to discuss any concerns or questions you may have with your doctor to determine the best course of action for your health.

Other Endoscopy Procedures


How is the procedure performed?
During a gastroscopy, the patient is usually sedated to minimize discomfort. The gastroscope is inserted through the mouth and passed down the swallowing pipe (esophagus) into the stomach and duodenum. Your doctor can view the images on a screen and may take biopsies if necessary.
After the procedure, you may experience some temporary side effects such as a sore throat, and bloating. You should also avoid strenuous activities for the rest of the day.
Your doctor may discuss preliminary findings with you immediately after the procedure. Biopsy results (if done) may take a few days to come back, and your doctor will discuss them with you during a follow-up appointment.
No, gastroscopy and colonoscopy are different procedures. Gastroscopy examines the upper digestive tract, while colonoscopy examines the colon and rectum.
A gastroscopy procedure in Singapore can vary in cost, typically ranging from SGD$400 to SGD$3000. The cost spectrum reflects different healthcare settings, with public hospitals offering the more affordable options, thanks to government subsidies. On the other hand, private hospitals, while pricier, provide advantages such as personalized care and expedited medical services.
