Reflux after gastric cancer resection may manifest as upwelling of gastroduodenal contents, vomiting and heartburn sensation. After gastric cancer resection, some patients may have the symptom of gastroduodenal contents surging into the pharynx or mouth without nausea and exertion, which may contain obvious sour taste. Symptoms of vomiting may occur after reflux, and the vomit contains bile. Burning pain behind the sternum or in the epigastric region can also occur due to the irritation of reflux, and the above symptoms can be aggravated after meals, lying down, bending over or when the intra-abdominal pressure increases. For people who have reflux and other uncomfortable symptoms after gastric cancer resection, comprehensive measures such as protecting gastric mucosa, acid suppression and regulating gastric motility are mostly adopted. Due to the reduction of gastric content, good dietary habits should be maintained in daily life, taking the form of appropriate small amount and multiple meals, regular and quantitative, light, nutritious and easy to digest diet, which can help to alleviate the reflux and other symptoms.
