What is heartburn and acid reflux?

"Heartburn" is sometimes used interchangeably with "acid reflux" and it is the burning sensation felt in the chest when stomach acid splashes up from the stomach into the oesophagus.


A gastroscopy (or gastrointestinal endoscopy) is a procedure where a thin, flexible tube, called an endoscope, is used to look inside the oesophagus, stomach and first part of the small intestine. The endoscope has a light and a camera at one end, which sends images of the inside of your oesophagus, stomach and duodenum to a monitor.

A gastroscopy can be used to investigate problems such as: difficulty swallowing or persistent abdominal pain. It is also used to diagnose conditions such as stomach ulcers or gastro-oesophageal reflux disease (GORD), as well as treat conditions such as: bleeding ulcers, a blockage in the oesophagus, non-cancerous growths (polyps) or small cancerous tumours.

When a gastroscopy is used to check symptoms or confirm a diagnosis, it is known as a “diagnostic gastroscopy”. When a gastroscopy is used to treat a condition, it is known as a “therapeutic gastroscopy”.

Frequently Asked Questions

How long does the procedure take?

About one hour

How long will I be in hospital?

Dr. Marr does most of his gastroscopies under conscious sedation in his rooms. This means that you go home the same day, you just need someone to drive you as you will feel drowsy after the procedure.

How, what and when can I eat after the procedure?

You will come to the procedure having not eaten from midnight the night before. You will be able to eat and drink normally after the procedure unless you have had to have a lesion removed, in which case you might have to have soft foods for a few days.

When can I resume normal activities?

You can go back to normal activities as soon as you have recovered from the conscious sedation.

When can I go back to work?

The next day.

How long will I have pain?

A gastroscopy is not normally painful unless a lesion or polyp is removed, in which case you may have pain and need painkillers for three to five days.

Will I need a follow-up visit?

You will not need a follow-up visit for the gastroscopy unless a biopsy is taken. You should probably have a routine annual check-up to review your symptoms and medication with Dr. Marr.
