General information, not an individual diagnosis. Ask a healthcare professional if you are unsure about your situation.
A gastroscopy lets the gastroenterologist examine the oesophagus, stomach and duodenum using a flexible tube with a camera. Samples may also be taken. Ask which question this already prescribed examination is intended to answer.
The doctor explains the procedure and seeks your consent. Local anaesthesia, sedation or general anaesthesia may be planned. Clarify which option applies, as it affects preparation and arrangements for getting home.
Fasting is required. Ask for precise instructions about food, drinks, smoking and medicines. Report all treatments, especially anticoagulants, allergies and illnesses; do not decide by yourself to stop a medicine.
If general anaesthesia is planned, an anaesthetic consultation takes place beforehand. Arrange for someone to accompany you home and do not drive that day. Bring the gastroscopy prescription, your medicine prescriptions and available reports.
Initial observations may be explained after the examination; final sample results take a few days. After local throat anaesthesia, wait until its effects have worn off before eating or drinking, following the instructions provided.
If you vomit blood after the examination, call 15 or 112 in France without delay. Before discharge, ask who will communicate biopsy results and when they will be reviewed. For other unusual symptoms after the examination, including abdominal or chest pain or fever, contact the doctor who performed it or seek very prompt advice from your usual doctor.
