Nausea, hiccups and vomiting after meals may be related to eating too fast, indigestion and gastroesophageal reflux disease. 1. Eating too fast: If you eat too fast, it may lead to increased peristalsis of the stomach, so that the food can not be well digested and absorbed in the stomach, which may lead to nausea, hiccups, vomiting and other symptoms after meals. 2. Indigestion: For patients who suffer from gastritis, gastric ulcer and other stomach diseases, eating certain stimulating and indigestible food may cause flatulence, which may lead to nausea, hiccups, vomiting and other symptoms after meals. 3. Gastroesophageal Reflux Disease (GERD): After suffering from GERD, the stomach contents may reflux into the esophagus, and when the food is over-fermented in the stomach, a large amount of gas will be produced, which will increase the pressure in the stomach and then cause nausea, burping and vomiting after meals, but at the same time, it may be accompanied by a feeling of fullness in the abdomen, a feeling of oppression, etc. If you have frequent nausea and vomiting after meals, you may have a feeling of fullness in the stomach. If the symptoms of nausea, burping and vomiting after meals occur regularly, it is recommended to go to the hospital as soon as possible to clarify the cause and treat the cause under the guidance of the doctor.
