Gastroscopy Procedures in Singapore


Patient FAQs about Gastroscopy Singapore

Q: Is gastroscopy painful?


A: Patients are typically sedated during the procedure, so they should not feel any pain. Some patients may experience mild discomfort or bloating afterward, but this usually subsides quickly.


Q: How often should I have a gastroscopy?


A: The frequency of gastroscopy screenings depends on factors such as age, medical history, and symptoms. Your healthcare provider can help determine the appropriate screening schedule for you.


Q: What should I expect after a gastroscopy?


A: After the procedure, patients may experience some throat discomfort or bloating. These symptoms usually resolve within a few hours, and patients can resume normal activities the same day.


Q: Can I eat immediately after a gastroscopy?


A: Patients are generally advised to wait until the effects of the sedative wear off before eating or drinking, which typically takes a few hours. Starting with clear liquids and then gradually moving to more solid foods as tolerated is recommended.


Q: Are there any risks associated with gastroscopy?


A: Gastroscopy is considered a safe procedure with a low risk of complications. However, as with any medical procedure, there are potential risks, albeit rare, such as reactions to the sedative, bleeding, or perforation (a tear) of the stomach or esophagus wall.

Gastroscopy in Singapore

In Singapore, where gastrointestinal health is a priority for many, gastroscopy is a procedure for diagnosing and treating various gastrointestinal conditions. In this guide, we will explore the ins and outs of gastroscopy, shedding light on its procedure, benefits, risks, and frequently asked questions.

What is Gastroscopy?


Gastroscopy, also known as Oesophago-Gastro-Duodenoscopy (OGD), is a minimally invasive procedure used to examine the lining of the upper digestive tract, including the esophagus, stomach, and duodenum. In Singapore, where digestive disorders are prevalent due to dietary habits and lifestyle factors, gastroscopy plays a role in diagnosing conditions such as gastritis, ulcers, and even early-stage cancers.


Gastroscopy is performed using a thin, flexible tube called an endoscope. This instrument contains a tiny camera and light source, allowing the gastroenterologist to visualize the internal structures of the digestive tract in real-time.


How is Gastroscopy Done?


During a gastroscopy procedure, patients are typically sedated to ensure comfort and minimize discomfort. Sedation is administered intravenously or through a combination of medications, depending on the patient's medical history and preferences. A local anesthetic spray will be used to numb your throat.


Sedation helps relax the patient and reduce gag reflexes, making the procedure more tolerable.


The examination takes about 10-20 minutes to complete. You may experience mild bloating or belching as air is inflated to distend the stomach. It is a procedure that is painless, and has no effect on your breathing.


Once sedated, the gastroenterologist gently inserts the endoscope through the mouth and guides it down the esophagus into the stomach and duodenum. Throughout the procedure, the gastroenterologist carefully examines the lining of the digestive tract, looking for abnormalities such as inflammation, polyps, ulcers, or tumors. If necessary, tissue samples (biopsies) may be taken for further analysis.


Gastroscopy is commonly performed as an outpatient procedure in Singapore. Patients are usually able to resume normal activities shortly after the procedure, although they may experience some mild throat discomfort or bloating.


What are the Benefits of Gastroscopy?


Gastroscopy enables early detection and diagnosis of various gastrointestinal conditions, including ulcers, inflammation, polyps and tumors. In Singapore, where early intervention is key to managing digestive disorders effectively, gastroscopy plays a crucial role in facilitating timely diagnosis and treatment.


In addition to diagnosis, gastroscopy allows for therapeutic interventions such as the removal of polyps, control of bleeding, and dilatation of strictures. These interventions can help alleviate symptoms and improve the overall health and well-being of patients in Singapore.


Gastroscopy is also used as a screening tool for detecting early-stage cancers of the upper digestive tract, including esophageal and gastric cancers. Regular screening is particularly important where the incidence of digestive cancers remains a significant health concern.


Are there any Risks in Gastroscopy?


While gastroscopy is generally considered safe, it carries some risks, including:

  • Perforation: In rare cases, the endoscope may cause a perforation or tear in the lining of the digestive tract. This complication requires immediate medical attention and may necessitate surgical repair.


  • Bleeding: There is a small risk of bleeding, particularly if a biopsy or therapeutic intervention is performed during the gastroscopy procedure. Most cases of bleeding are minor and can be managed conservatively.


  • Adverse Reactions: Some patients may experience adverse reactions to the sedative medications used during the procedure, such as respiratory depression or allergic reactions. These reactions are rare but should be monitored closely by healthcare providers.




Gastroscopy is a valuable tool for maintaining digestive health and diagnosing gastrointestinal conditions in Singapore. By understanding the procedure, its benefits, risks, and what to expect, individuals can make informed decisions about their healthcare.
