Gastroscopy Screening in Singapore

What Is a Gastroscopy?

Gastroscopy is a procedure that helps a doctor examine the inner lining of the upper gastrointestinal (GI) tract, including the oesophagus, stomach, and the first portion of the small intestine (duodenum). This is done using a long, flexible tube with a camera (gastroscope) inserted through the mouth and threaded down into the stomach, with the purpose of diagnosing abnormalities or providing certain forms of treatment.

Singapore gastroscopy can help to detect underlying upper digestive disease that are often overlooked as abdominal pain, such as gastroesophageal reflux disease (GERD), ulcers, oesophageal stricture, coeliac disease, Barrett’s oesophagus, hiatal hernia, oesophageal varices, and stomach cancer.

Our gastroscopy doctor has close to two decades’ specialist experience in gastroscopy and general surgery.

Who Should Go for a Gastroscopy?

A gastroscopy doctor in Singapore may recommend an individual to undergo this diagnostic procedure for the following reasons:

  • Persistent abdominal pain and discomfort
  • Any abnormal findings, such as precancerous growths (polyps) or stomach ulcers
  • Suspected stomach cancer
  • Gastrointestinal bleeding or anaemia
  • Identifying the cause of symptoms, such as swallowing difficulties, inflammation, nausea and vomiting, heartburn and acid reflux, and unexplained weight loss

How to Prepare for Your Gastroscopy

For patients who will undergo gastroscopy in Singapore, they need to take some steps beforehand in preparation for the procedure, including:

  • Fasting - Refraining from eating or drinking anything for 4 to 6 hours prior to the examination is needed. Instead, patients are advised to only consume clear liquids, such as water, for up to 2 hours before the appointment as having an empty stomach is crucial in helping the doctor clearly visualise the entire GI tract.
  • Certain Medications - Avoid taking certain medications that may cause blood clotting. These include blood thinners, aspirin, and high blood (hypertension) and diabetic medications. Follow doctor’s advice or discuss the list of safe medications and dosages that can be taken before the procedure.
  • Arrange Someone to Take You Home - Since esophageal gastroscopy can sometimes be done under sedation, you may feel drowsy and disoriented afterwards and hence should arrange for someone to bring you home afterwards. However, if you only had a numbing throat spray, you can then be left to head home by yourself once the doctor has discharged you.
What to Expect During Your Gastroscopy Screening
  • Before the Procedure - Before undergoing gastroscopy screening in Singapore, patients should discuss with their doctors on when to take regular medicines, or if they are suffering from allergies or other health conditions that may affect the procedure’s result. They will also perform a final evaluation before proceeding to the operating room.
  • During the Procedure - Gastroscopy is an outpatient screening procedure that usually takes only 15 to 45 minutes. In this procedure, the doctor either administers an anaesthetic throat spray for throat numbness or an intravenous sedation. A plastic mouthpiece will be used for dental protection and to hold the mouth open. A gastroscope will be slowly inserted through the mouth and into the stomach to examine the gastric lining of the oesophagus, stomach and small intestine (duodenum) and perform biopsy (tissue sample) if any abnormalities are present.
  • After the Procedure - Once the examination is done, patients will be taken to a recovery room to rest until the sedation wears off. It is common for patients to experience mild and temporary postoperative effects, including a mild sore throat or bloating, which will resolve within a few days. The doctor will also set a follow-up appointment to discuss the procedure and findings.
A gastroscopy can detect a wide range of digestive issues so that you can commence prompt treatment.

What do my gastroscopy results mean?

A gastroscopy is used to examine digestive symptoms, such as indigestion, nausea, or swallowing problems of digestive pain. The findings may also help to identify the presence of an inflammation, ulcer, abnormal growths, or any serious health condition, such as coeliac disease or gastroesophageal reflux disease (GERD), which might affect the upper GI tract.

Is there any downtime after a gastroscopy?

Gastroscopy services require minimal downtime as patients are able to return to their normal activities within 1 to 2 days after the procedure.

How long should I stay in the hospital after a gastroscopy?

After undergoing a gastroscopy, patients will remain at the hospital for a 1- to 2-hour rest to allow the sedation to wear off. Your gastroscopy doctor will also conduct follow-up monitoring and post-procedure assessments.

How much does a gastroscopy cost in Singapore?

Gastroscopy cost in Singapore depends on factors such as the type of procedure, doctor’s fee, hospital rate, and sedation fee, among others. The patient’s insurance coverage will also further determine the final amount. Please contact the gastroscopy clinic or hospital for more personalised and accurate advice on cost.

What should I avoid after gastroscopy?

24 hours following the procedure, patients should rest at home and abstain from drinking alcohol, driving, or taking any sedatives or medications that cause drowsiness.
