Consumption of food or defoaming and bubbling (derived from intestinal gas in combination with gastric juice, or bile) can cause abdominal pain, visual impairment, and affect the diagnostic accuracy. Therefore, fasting for at least 6-8 hours and/or administration of prokinetic (intravenous erythromycin) or anti-foaming (oral simethicone) drugs is recommended prior to the application of gastroscopy.

Gastrointestinal endoscopy is a method of screening and accurately detecting lesions occurring in the digestive tract that are difficult to detect with other diagnostic methods.

Simethicone preparation for upper gastrointestinal endoscopy effectively reduces foam accumulation in the esophagus, stomach and duodenum, helping to observe and diagnose small lesions more clearly and accurately. As a result, therapeutic endoscopy is performed smoothly and quickly, reducing irritation and discomfort for the patient.
