Examination of the oesophagus, stomach and upper bowel, performed personally by Dr Deepak Kejariwal, Consultant Gastroenterologist, at Cobalt Hospital, usually within one to two weeks of your enquiry.
What is a gastroscopy?
Gastroscopy is a routine, well-established procedure used to examine the lining of your oesophagus, stomach and the first part of your small bowel, and it is one of the most effective ways to find the cause of persistent digestive symptoms. Also known as an upper GI endoscopy or OGD (oesophago-gastro-duodenoscopy), the test involves a thin, flexible camera passed gently through the mouth to allow direct visual inspection of these areas, according to current NHS guidance on gastroscopy, updated in August 2026 (NHS, 2026).
Patients across Newcastle upon Tyne, Durham, North Tyneside, Gateshead and Sunderland choose to see Dr Deepak Kejariwal for private gastroscopy because of his 18+ years of consultant experience. A gastroscopy is typically recommended to investigate symptoms such as persistent indigestion, reflux, difficulty swallowing, unexplained weight loss, abdominal pain or anaemia, and it allows biopsies to be taken where needed to confirm a diagnosis. If you are also experiencing lower bowel symptoms, Dr Kejariwal can arrange a colonoscopy or wider private endoscopy assessment at the same visit.
Why timely investigation matters
Digestive symptoms are common, but persistent or worsening symptoms deserve proper investigation rather than long-term self-management with over-the-counter remedies. In 2026, NHS waiting times for routine upper GI endoscopy remain a significant concern for many patients in the North East, which is why private gastroscopy has become an increasingly popular route to fast, accurate diagnosis without a long wait. Early investigation also matters clinically: conditions such as stomach ulcers, coeliac disease and early-stage cancers are far easier to treat when identified promptly, and a gastroscopy is often the single most useful test for ruling these in or out.
Preparation
You will be asked to avoid food for around six hours before your appointment and clear fluids for two hours beforehand, to ensure the stomach is empty and the examination is as clear and safe as possible. Specific fasting instructions, along with guidance on any regular medication, are confirmed in writing with your appointment and repeated by the team on arrival at Cobalt Hospital.
If you take blood-thinning medication, have diabetes, or have any allergies, please let the team know in advance so preparation can be tailored accordingly.
What happens on the day
01
Arrival & preparation
Check in at Cobalt Hospital day unit. The team talks you through consent and any sedation choices, including a mild throat spray or, if preferred, sedation to help you relax throughout the procedure.
02
The procedure
The gastroscopy itself usually takes between 10 and 20 minutes. Dr Kejariwal performs the examination personally, carefully assessing the oesophagus, stomach and duodenum, and taking biopsies if required.
03
Recovery
A short rest in the recovery bay follows, longer if you have chosen sedation, in which case you will need someone to accompany you home and should not drive for 24 hours.
04
Results, the same day
Dr Kejariwal explains what he found before you leave, with a written report to follow to you and your GP. Biopsy results, where taken, typically follow within one to two weeks.
Risks and safety
A gastroscopy is a well-established and generally very safe procedure. As with any endoscopic examination, there is a small risk of discomfort, a sore throat, or minor bleeding, particularly if a biopsy is taken. Serious complications such as perforation are rare, occurring in roughly 1 in 10,000 procedures nationally. Dr Kejariwal will discuss the specific risks relevant to you as part of the consent process, so you can make an informed decision with confidence.
Your results
Findings are explained by Dr Kejariwal on the day where possible, with a written report sent to you and your GP. If biopsies have been taken, these results are communicated promptly by phone or in a follow-up appointment, with a clear plan for any further treatment.
Frequently asked questions about gastroscopy
What is a gastroscopy used for?
A gastroscopy is used to find the cause of upper digestive symptoms such as indigestion, reflux, swallowing difficulty, or unexplained weight loss, and to take biopsies or treat certain conditions found during the examination.
Will I be sedated for my gastroscopy?
Sedation is optional. Many patients choose a local anaesthetic throat spray only, while others prefer sedation for comfort. Dr Kejariwal will discuss the best option for you at your consultation.
How do I prepare for a gastroscopy?
Fasting from food for around six hours and clear fluids for two hours beforehand is required. Full written instructions are provided with your appointment confirmation.
When do I get my gastroscopy results?
Initial findings are usually shared with you on the same day. Biopsy results, if taken, are typically available within one to two weeks.
What does a private gastroscopy cost in Newcastle?
Costs vary depending on whether biopsies or additional tests are needed. Contact the team for a personalised quote and self-pay or insurer-recognised options.
Is gastroscopy painful?
Most patients experience mild discomfort rather than pain. The throat spray or sedation offered helps keep the procedure as comfortable as possible.
