Is Gastric Endoscopy Painful?

Many people are concerned about whether gastric endoscopy is painful. What is the answer?

Potential Causes of Pain:

  • Stress and Anxiety: These can cause the body to react adversely.
  • Gag Reflex: Nausea and vomiting may occur when the endoscope is introduced into the esophagus.
  • Additional Procedures: Auxiliary procedures like biopsies or polyp removal performed during the endoscopy can cause mild pain.

Frequently Asked Questions About “Is Gastric Endoscopy Painful?”

Does Gastric Endoscopy Induce Nausea?

Answer: Gastric endoscopy, especially the traditional method through the mouth, can trigger the gag reflex and cause nausea in some individuals. However, this sensation can be alleviated by relaxing, having a good psychological preparation, or opting for transnasal endoscopy or sedation endoscopy.

I am very afraid of gastric endoscopy. Are there alternative methods to examine the stomach?

Answer: Although gastric endoscopy is the most effective method to directly observe the stomach lining, some less invasive techniques can also be used, such as barium X-rays and ultrasound. However, these techniques may have lower accuracy in detecting small lesions.

Can I eat immediately after a gastric endoscopy?

Answer: Generally, you need to wait about 30 minutes after a conventional endoscopy before you can eat or drink again. With sedation endoscopy, your doctor may require you to fast longer until the sedative effects wear off.

The cost of pain-free gastric endoscopy?

Answer: The cost of pain-free gastric endoscopy is typically higher than conventional endoscopy. The specific price depends on the medical facility, the anesthesia technique, and any additional procedures. Costs can range from one to several million VND.
