Expert Private Gastroscopy in West Yorkshire

What is a Gastroscopy?

A gastroscopy, also known as an upper endoscopy or OGD (oesophago-gastro-duodenoscopy), is a procedure that allows a specialist to examine the oesophagus, stomach, and the first part of the small bowel using a thin, flexible camera. It provides a clear, real-time view of the digestive tract and is one of the most accurate tests for diagnosing upper gastrointestinal (GI) conditions.

A gastroscopy is often performed to investigate symptoms such as acid reflux, indigestion, difficulty swallowing, persistent nausea, upper abdominal discomfort, unexplained weight loss, and iron-deficiency anaemia. It also allows treatment to be carried out during the same procedure, such as taking biopsies, removing small polyps, treating bleeding, or stretching narrow areas (strictures).

Why a Gastroscopy is Recommended

A gastroscopy may be advised to diagnose the cause of ongoing upper GI symptoms that have not improved with medication or lifestyle changes. It is used to evaluate conditions including gastritis, oesophagitis, stomach ulcers, coeliac disease, Barrett’s oesophagus, and early signs of cancer. It is also used to look for Helicobacter pylori, a common cause of inflammation and ulcers.

Monitoring of known conditions, such as Barrett’s oesophagus or gastric polyps, is another common reason for this test.

How to Prepare for a Gastroscopy

For clear views of the stomach, fasting is necessary. You will be asked not to eat or drink for at least six to eight hours before the procedure. Your hospital will provide detailed instructions about medications, including whether any adjustments to blood thinners or antacids are needed.

What Happens During a Gastroscopy

Before the procedure, the process and risks will be explained. You may choose throat spray (local anaesthetic), sedation, or occasionally no anaesthetic. You will lie on your side while a slim camera is gently guided through the mouth into the oesophagus, stomach, and duodenum. Air or carbon dioxide is introduced to open the stomach so the lining can be examined clearly. Biopsies or treatment can be performed immediately if required.

After the Procedure

You will recover in a designated area until the effects of sedation or throat spray have worn off. Eating and drinking can usually restart after about an hour. Most patients return home the same day. A mild sore throat or bloating may occur for a few hours. You must not drive for 24 hours if sedation has been used.

Biopsy results are usually ready within a few days.

Risks of a Gastroscopy

Gastroscopy is a very safe procedure. Complications are uncommon but can include bleeding (especially after biopsies or polyp removal), perforation (a rare tear in the lining, approximately 1 in 5,000–10,000 procedures), and aspiration if fasting instructions are not followed. Your surgeon will discuss these risks with you beforehand.

When to Seek Urgent Medical Advice After a Gastroscopy

You should contact the hospital or seek urgent assessment if you experience severe abdominal or chest pain, vomiting blood, passing black stools, shortness of breath, or a high temperature after the procedure.
