Gastroscopy

This procedure is typically recommended for patients experiencing persistent or unexplained symptoms, which can include:

• Reflux and Heartburn: A persistent burning feeling in the chest or throat, often after meals, is a classic sign of GERD. This can be accompanied by regurgitation (a sour taste in the mouth), belching, and a sensation of a lump in the throat
• Upper Abdominal Pain (Dyspepsia): Pain or a burning sensation in the epigastric region (between the navel and lower chest). This is often accompanied by feelings of postprandial fullness (feeling overly full after eating) and early satiety (inability to finish a normal meal). The pain may worsen or improve with eating
• Difficulty Swallowing (Dysphagia): A sensation that food is stuck in the throat or chest, which can be a sign of strictures or tumors
• Gastrointestinal Bleeding: This can manifest as hematemesis (vomiting blood, which may look like bright red blood or coffee grounds) or melena (black, tarry stools indicating bleeding in the upper GI tract)
• Unexplained Anemia: Iron-deficiency anemia, especially when accompanied by other symptoms or in older adults, is a key indicator of potential chronic bleeding in the gut
• Nausea and Persistent Vomiting: Ongoing or unexplained nausea and vomiting that does not resolve may require endoscopic evaluation

A gastroscopy is crucial for diagnosing a range of conditions, including Gastroesophageal Reflux Disease (GERD), esophagitis, peptic ulcers, gastritis, Barrett's esophagus, and Celiac disease. It is also the primary method for detecting early-stage cancers of the esophagus or stomach.

A gastroscopy allows the doctor to examine your oesophagus, stomach, and duodenum. To obtain clear images and avoid complications, you must have an empty stomach.

• Fasting: Do not eat or drink anything for at least 6–8 hours before the procedure. This includes water, tea, coffee, and chewing gum. An empty stomach reduces the risk of vomiting and improves visibility
• Medications: Inform your doctor about all medications you take, especially blood thinners (e.g. warfarin, clopidogrel, apixaban), insulin, or iron supplements. You may need to adjust or stop some of them temporarily
• Diabetes management: If you have diabetes, discuss your insulin or oral medication schedule with your doctor to avoid hypoglycaemia during fasting
• On the day: Arrive at the clinic with a responsible adult who can drive you home, as sedation is often used and impairs your ability to drive
