Oily food is more difficult to digest in the stomach and can be a burden to the digestive system, especially for people who have a weak spleen and stomach themselves, eating oily food can cause nausea and vomiting, so you can take Gastric Relief Tablets. The main function of the tablets is to improve the bloating and indigestion caused by the weakness of the spleen and stomach, to enhance the gastric power, to promote the emptying of food in the stomach, and to avoid nausea and vomiting. Morpholine is a gastric motility drug, which can also coordinate the movement of stomach and duodenum to avoid the retention of food in the stomach, and can enhance the tone of esophageal sphincter, which has the effect of inhibiting vomiting. Greasy food entering the stomach will stimulate the gastric glands to secrete gastric acid, and too much gastric acid will cause nausea and vomiting due to irritation of the stomach wall, which can be treated with omeprazole.
