One of the tests that cannot be missed in health checkups or digestive disease diagnosis is gastroscopy no see.

But what more people are curious about than the prosecutors is Fasting time for gastroscopy no see.
Failure to follow the correct fasting method may affect the test results.

In severe cases, the test itself may be canceled! I've seen several people around me have had their tests canceled because they didn't fast properly.

 

In this article, we will cover everything from the 12-hour fasting period for gastroscopy to food and water intake the day before and precautions for general anesthesia.
Let's summarize the most frequently asked questions.

 

Why is fasting necessary for gastroscopy?

 

Gastroscopy is a test that observes the stomach and duodenum by inserting an endoscopic camera through the mouth or nose.

If there is food left in the stomach at this time, the field of vision is obstructed, making an accurate diagnosis difficult.
Especially when under general anesthesia, food may reflux into the airway, creating a dangerous situation.

 

Therefore, it is generally recommended The minimum fasting time for gastroscopy is 8 hours.
To be safe, it is best to fast for 12 hours before the gastroscopy.

 

 

Food the day before gastroscopy

 

So what should I eat the day before the test?

The day before your gastroscopy, you should choose foods that are mild and easily digestible.

 

Recommended foods

- White porridge, rice cake soup
- Clear broth
- Soft tofu, steamed eggs

 

 

Foods to avoid  

- Red pepper powder, oily foods
- Fruits with seeds (melons, watermelons, etc.)
- Seaweed (wakame, laver, etc.)

 

 

These foods may take longer to digest or leave residue in the stomach, which may interfere with the examination.

 

Can I drink water after an upper gastrointestinal endoscopy?

 

Many people ask, “Can I drink water after a gastroscopy?”
A small amount of water is okay, but you should avoid drinking water for two hours before the test.

especially milk, coffee, juice The back covers the stomach mucosa and stimulates gastric acid secretion.
It should be avoided as it interferes with accurate examination.

 

👉That is, during the gastroscopy fasting period, Water supply is also stopped 2 hours before testing. It is safe to do so.

 

 

Precautions during gastroscopy under general anesthesia

 

To reduce examination anxiety and receive the examination comfortably Gastroscopy with sedation is often chosen.

But in this case, the gag reflex is weakened due to the anesthesia,
If food remains in the stomach, it can pass into the airway, which can be dangerous.

 

Therefore, if you are under general anesthesia, you must fast for 12 hours before the gastroscopy.
Until just before the inspection Strictly prohibit consumption of water or food Must do.

 

 

Meals after gastroscopy

 

When can I eat after the test is over?

After gastroscopy, eating is usually done after the examination. 1~2 hours later, It is safe to begin after the anesthesia in the neck has worn off.

At first, it is recommended to eat small amounts of soft, non-stimulating foods such as soup or porridge.
It is recommended to avoid spicy foods and alcohol for at least one day as they can put a strain on the stomach lining.
