What to Expect Before the Procedure
You may receive a sedative to help you relax during the procedure. Your doctor will explain how to prepare, including fasting for several hours beforehand. Wear comfortable clothing and avoid heavy meals or liquids.
During the Procedure
A healthcare provider will insert a thin, flexible tube called an endoscope through your mouth into your stomach and duodenum. The endoscope allows your doctor to see inside these areas. If a biopsy is needed, small tissue samples will be taken for lab analysis.
Aftercare and Recovery
After the procedure, you may feel sore or have mild discomfort. You’ll likely need someone to drive you home due to the sedative. Avoid heavy meals or strenuous activity for a few hours. Follow your doctor’s instructions for any prescribed medications or follow-up tests.
Why This Test Is Performed
This test helps diagnose conditions such as stomach ulcers, acid reflux, inflammation (like gastritis), or abnormal growths (such as polyps or early signs of cancer). It can also check for signs of infection or other gastrointestinal issues.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
Clinical Significance: This procedure provides direct visualization of the stomach and duodenum, allowing for early detection of serious conditions that may not be identified through blood tests or imaging alone. Biopsies can confirm diagnoses like Helicobacter pylori infection, tumors, or chronic inflammation, guiding treatment decisions.
