Gastroscopy for polyps generally does not cause inflammation as long as it is reasonably treated. Gastroscopy for polyps is a minimally invasive surgery, after the operation, the resection site is a transient local inflammatory reaction, but under medication, these inflammations will generally disappear in a short period of time. Postoperative treatment is generally used to inhibit gastric acid and protect the gastric mucosa of the drug treatment. Omeprazole and rabeprazole can be used to inhibit gastric acid, this treatment is used to reduce the secretion of gastric acid, reduce the stimulation of gastric acid on the wound and prevent the spread of inflammation. To protect the gastric mucosa, aluminum sulfate and magnesium aluminum carbonate chewable tablets can be used, and this treatment is used to isolate the gastric acid from the wound and promote the recovery of the wound. After the above medication, the local inflammation will soon subside and will not cause widespread inflammation, so generally speaking, doing gastroscopy to cut polyps will not cause inflammation. All of the above medications should be used under the guidance of a doctor, avoid self-medication, and should be regularly reviewed and follow the postoperative medical advice.
