Nausea, vomiting and diarrhea like water may be due to intestinal inflammation, food poisoning, gastrointestinal tract dysfunction and other reasons. 1. Acute bacterial inflammation of the intestinal tract may cause acute hypersecretion of gastrointestinal glands, as well as gastrointestinal smooth muscle spasm, resulting in nausea and vomiting as well as watery stools. 2. In cases of food poisoning, the gastrointestinal tract secretes large quantities of digestive fluids such as intestinal juices, which can cause watery stools and nausea and vomiting. Usually there is a history of unclean eating. 3. Gastrointestinal disorders, such as irritable bowel syndrome, can be triggered by cold and other triggers, resulting in gastrointestinal symptoms such as nausea and vomiting with watery stools. The pathologic process is unknown and may be related to immune and psychiatric factors. In conclusion, it is recommended that patients take into account their dietary and medical history as well as specialized examinations and be advised by their physicians for further treatment.
