What is Gastroscopy

A tube (endoscope) with a camera attached to the tip is inserted through the mouth or nose, and the doctor in charge checks the internal conditions of the esophagus, stomach, and duodenum. The mucosa can be directly observed, and if there is a suspicious lesion, a biopsy or treatment can be performed during the examination to extract the tissue.
Therefore, this examination can lead to a definitive diagnosis of a wide range of diseases.

3 Is endoscopy a painful procedure?

Endoscopies aren’t usually painful because most patients receive a sedative injection before the procedure starts. The sedative makes you sleepy or helps you relax, and it may make the entire process more comfortable, so you typically don’t feel any pain during the procedure.

4 How long does a endoscopy take?

A endoscopy typically takes about 30 minutes, depending on whether the doctor needs to remove tissue or if testing is difficult for any reason.

However, patients are required to rest at the clinic for about one hour after the procedure is finished.
This means that the total time needed for the procedure and recovery is usually about 2 hours.

5 Can I go to work after the procedure?

After the procedure, you should not go back to work or do any activities that require alertness and concentration for the rest of the day. The sedative used during the exam can affect your ability to make important decisions, drive, or operate heavy machinery. Because it can take up to a day for the full effects of the sedative to wear off. It is always best to follow the advice of your healthcare provider to ensure your safety and well-being.

6 What is the best meal after the endoscopy?

On the same day, it’s best to eat foods that are easy to digest. After confirming that there is no abdominal pain or bleeding on the next day, gradually return to a normal diet over a period of about 1 day, starting with foods that are easy to digest. It’s recommended to avoid spicy foods such as chili peppers, strong stimulants, and alcohol for about 2 days after the examination.

The recommendations may vary depending on the individual’s condition. So it’s always best to consult with a doctor after a endoscopy.
