Why might endoscopy be advised?
A gastroenterologist may recommend endoscopy after reviewing your symptoms, medical history and previous tests. It can help assess inflammation, ulcers, narrowing and other upper digestive-tract concerns, and allows small tissue samples to be taken when clinically appropriate.
Preparing for the procedure
You will receive individual fasting and medicine instructions. Tell the clinical team about allergies, diabetes, pregnancy, heart or lung conditions and every medicine or supplement you take—especially blood-thinning medicines. Do not change prescribed medicines unless your clinician instructs you to.
What to expect
The endoscope is carefully passed through the mouth while you lie on your side. Throat-numbing medicine and sedation may be used depending on the plan. If sedated, arrange for a responsible adult to take you home and follow all discharge instructions.
Recovery and warning signs
Temporary bloating or a mild sore throat can occur. Seek urgent medical attention for breathing difficulty, worsening chest or abdominal pain, fever, vomiting blood, black stools or worsening swallowing problems after the procedure.
Questions patients often ask
Does an endoscopy affect breathing?+
The endoscope passes through the food pipe rather than the airway. Your clinical team monitors you throughout the procedure.
Can a biopsy be taken?+
Small tissue samples may be taken when clinically appropriate. Your doctor will explain any planned sampling and how results are reviewed.
Is endoscopy right for every patient?+
No. The decision depends on symptoms, health history, examination and alternative tests. A consultation is needed for individual advice.
