Gastroscopy Singapore: Here’s what to Expect after the Procedure

Gastroscopy is usually performed by qualified endoscopists. It should take less than 15 minutes but may take longer if you're getting it to treat a condition.

To prepare for this procedure, the endoscopist, helped by nurses, will spray a local anaesthetic to numb your throat. Alternatively, you may be treated with a sedative injection to help you relax during the procedure.

Usually, your General Practitioner (GP) will recommend gastroscopy if they’ve noted symptoms of a possible condition that may be diagnosed by this procedure. If your GP has recommended gastroscopy in Singapore, get in touch with Dr Ganesh (General Surgeon in Singapore)- Gallbladder Removal, Hernia Surgery, Colonoscopy, Gastroscopy.

He will advise you on the important things you may need to observe before gastroscopy. From the appointment, you will also know what to expect during the procedure.

Is it Normal to have Stomach Pain after Gastroscopy?

You will not necessarily experience much stomach pain after gastroscopy. Instead, you will experience bloating or sore throat, which is normal and may last for around 24 to 48 hours following your treatment.

Therefore, a mild stomach or abdominal pain after gastroscopy is normal. You should not overlook severe stomach pain though. Importantly, you should get in touch with the endoscopy unit or your GP if you experience severe or worsening abdominal or stomach pain. 

You will also need to contact the endoscopy unit or doctor if you experience high temperatures averaging 38ºC or more, vomit blood or experience persistent vomiting, shortness of breath and if you pass ‘tar-like’ or dark stool, which may be a sign of extensive internal bleeding. It is important to note that if you consented to a sedative injection, apart from keeping you relaxed, it would also make you feel drowsy.

Due to the effect of the sedative medication, you will be required to avoid most activities, including driving. Most notably, you will need to have someone who will pick you up from the facility and keep an eye on you for at least one day. 

Here are a Few more things you can Expect after Gastroscopy in Singapore

If you had just an aesthetic sprayed on your throat, you could expect to go back home soon after your gastroscopy in Singapore. Before being discharged, you may get the results of your gastroscopy. 

There are, however, instances, for example, if tissue samples were taken for biopsy where you may need to schedule an appointment at a later date to discuss your results. You may also need to make subtle changes to your diet after gastroscopy in Singapore. Your provider will let you know about this before you’re discharged from the facility.

What do you do after a Gastroscopy?

You can always eat food and drinks normally after the aesthetic used to numb your throat has worn off—usually one hour after the procedure. However, you will need to avoid drinking alcohol or taking tranquillisers, sedatives, and sleeping pills for the first 24 hours after your gastroscopy in Singapore.

Regarding the specific types of foods you can eat after gastroscopy, it is recommendable that you eat small meals that majorly consist of soft and easily digestible foods. Some of the foods you can enjoy in this case, therefore, include soups, juices, and eggs, etc. You can always resume your regular diet when you feel that you’re back to normal.

What Preparation is needed for Gastroscopy?

Even though gastroscopy isn’t really complicated, it requires careful preparation to get the best results and also minimise the risks of possible complications. Therefore, it is imperative that you carefully follow the preparation instructions for gastroscopy in Singapore. 

When preparing for gastroscopy in Singapore, you will also need to understand and acknowledge the risks of this exam. It is mostly safe but comes with a few risks and complications you may need to understand before consenting for the assessment.

For instance, you may experience bleeding, especially if it will involve taking tissue samples for biopsy. This bleeding is usually not severe and should subside within just a few days after your treatment.

Other than bleeding, the other complications that may also come up but very rare include adverse reactions to the sedatives used during this procedure, aspiration whereby liquid or food drops into the lungs and tearing. You can significantly avoid these risks by preparing adequately for the procedure and following your doctor’s guidelines.

Here are some of the preparation basics you may need to observe before having this procedure;

  • Spicy foods, chocolate alcohol, seeds, and nuts. It would be better to avoid these types of food for around two days before gastroscopy.
  • Your last ‘heavy’ meal should be taken no later than 6 PM on the day before having gastroscopy in Singapore. It is prudent that you observe this recommendation to ensure that you get accurate results from your examination. This is because; the results from gastroscopy exams are usually dependent on the stomach being empty. If there are food particles in your stomach at the time of the procedure, chances are high they may conceal essential hints that can help in diagnosing certain conditions.
  • On the day of your examination, you will need to avoid taking any food or beverage. The only exception is a little water, which you should only take not later than 2 to 4 hours before the procedure.
  • If you had been taking any medication for chronic conditions in pills or capsules, you might also need to discontinue taking them to avoid the risks of foreign objects in your stomach distorting the results of this exam. You will also need to discontinue medications that may increase your risks for bleeding. Some of the medications in this category include; warfarin, anti-inflammatory drugs, aspirin, heparin, and any blood thinning medication or supplement.
  • Be sure to inform your doctor about any allergic reactions you could be having. This will be even more important if your allergic reactions are linked to drugs. As mentioned early, you may be given anaesthetic medication to minimise discomfort and suppress the gag reflux you may experience when the endoscopist inserts the endoscope into your throat for this examination. If you develop allergic reactions to certain drugs, your doctor will need to confirm that you’re safe to get the anaesthesia medications.
