How long after a gastroscopy can you eat a hamburger?

Gastroscopy refers to the examination of the stomach using an endoscope. Under normal circumstances, one can eat a hamburger 2 to 24 hours after completing a gastroscopy. If discomfort symptoms such as abdominal pain, nausea, or vomiting occur after the procedure, medical attention should be sought promptly, and dietary adjustments should be made according to the doctor's advice.

If no biopsy or other procedures were performed during the gastroscopy, in general, liquid diet can be consumed 2 hours after the examination, and regular diet—including solid foods such as hamburgers and corn—can typically be resumed after 24 hours. However, if a biopsy or other interventions were performed during the gastroscopy, the fasting period should be extended appropriately. The specific timing should be discussed with the doctor and determined based on individual conditions and medical recommendations.

After gastroscopy, the mucosal lining of the digestive tract may experience some degree of trauma; therefore, meals should be mild and irritating foods—such as chili peppers, alcohol, coffee, and strong tea—should be avoided. During the first few days following the procedure, it is recommended to eat small amounts frequently, avoiding excessive food intake that could increase the burden on the gastrointestinal tract. After gastroscopy, it is important to develop healthy eating habits, maintain regular meal times, and avoid overeating.

It is important to note that after a gastroscopy, diet should gradually progress from liquids to semi-liquids, soft foods, and then back to a normal diet. Therefore, even if hamburgers are allowed, they should be eaten in moderation to prevent placing excessive strain on the gastrointestinal system.
