Gastroscopy Procedures: What to Expect, Preparation, and Safety

If you’re preparing for gastroscopy procedures, this guide is here to help you feel informed and confident. A gastroscopy procedure uses a thin, flexible tube with a small camera to examine the lining of your esophagus, stomach, and the first part of your small intestine. During gastroscopy procedures, you may receive sedation to help you relax. Most people report only mild discomfort and describe a gentle sensation of pressure as the scope passes through the throat. The procedure typically lasts about 15 to 30 minutes, and biopsies can be taken if something appears unusual. Afterward, you might have a sore throat or a little bloating, which usually subsides within a day. If you have concerns about sedation or medical conditions, discuss them with your healthcare team before the procedure. Preparation for gastroscopy procedures is key to safety and comfort. Your clinician will provide specific instructions, but common steps include fasting after midnight (no food or drink for a defined period before the procedure), avoiding heavy meals the day of the test, and arranging transportation home since you may not be able to drive yourself. Tell your doctor about all medications, supplements, and allergies, especially if you take blood thinners or have a history of reactions to anesthesia. On the day of your procedure, wear comfortable clothing and bring a list of medications, your insurance details, and a trusted companion if possible. If you’re exploring ways to support your gut health around medical procedures, you can learn more about at-home testing and insights through the InnerBuddies microbiome test: InnerBuddies microbiome test. Safety tips are essential for peace of mind. The risk of complications from gastroscopy procedures is generally low, but you should be aware of potential issues such as infection, bleeding if a biopsy is performed, or a reaction to sedation. Follow all fasting and medication instructions precisely, and report any worsening symptoms to your healthcare team promptly after the procedure. Aftercare typically includes resting for a short period, staying hydrated, and gradually resuming normal meals as advised. If you notice severe chest pain, persistent vomiting, fever, or signs of infection, seek medical attention right away.
