Vomiting with food and water is associated with gastroenteritis, digestive disorders, food poisoning and other factors. There are more causes of nausea, vomiting and gastrointestinal discomfort in humans. In adults, vomiting after eating is mainly considered to be caused by poor gastrointestinal or acute gastroenteritis. Infectious factors such as bacteria, viruses, salmonella and staphylococcus aureus can lead to acute gastrointestinal inflammation in the human body. Patients experience sudden abdominal pain and diarrhea, which can affect the function of the gastrointestinal tract and cause nausea and vomiting. Long-term poor dietary habits can lead to digestive tract dysfunction, abnormal peristalsis of the digestive tract, inability to be digested and absorbed after food intake, and high pressure in the gastrointestinal tract leading to food reflux, causing vomiting manifestations. If you do not pay attention to the diet, the intake of spoiled or contaminated food, resulting in harmful substances into the human gastrointestinal tract, causing stimulation of the gastrointestinal tract will cause vomiting or diarrhea.
