Diarrhea, nausea and vomiting may be caused by food poisoning, acute gastrointestinal infections or tumors, but also due to systemic diseases such as hepatic and renal insufficiency, adverse reactions to medications, etc., and you need to consult a doctor in a timely manner to determine the cause of the disease.
1. Food poisoning: after eating spoiled and expired food or food containing toxins, such as poisonous mushrooms, long soaked fungus, etc., the toxins or pathogenic microorganisms multiply in the human body to produce enterotoxins or release endotoxins, which stimulate the intestinal wall cells to absorb sodium and water, leading to excessive secretion of intestinal fluids and chlorine ions, causing gastrointestinal dysfunction, producing nausea, vomiting, diarrhea and other symptoms.
2. Acute gastrointestinal infection: nausea, vomiting and diarrhea may be caused by acute gastrointestinal infection, due to unclean diet, leading to bacterial, viral and other pathogens infections, such as Escherichia coli, rotavirus, norovirus, etc., which enter into the digestive tract and reproduce in the digestive tract, inflammatory infections of digestive tissues, gastrointestinal and digestive dysfunction, and in severe cases, can lead to dehydration and even shock.
3. Tumor: this kind of situation is more special, and the patients themselves have more serious underlying diseases. For example, if the condition of patients with intestinal tumor is aggravated, the tumor cells spread and the barrier function is damaged, nausea, vomiting, diarrhea and other symptoms will appear.
It should be noted that the above are only common causes of nausea, vomiting and diarrhea, but also intestinal dynamics diseases, systemic diseases (such as liver and kidney failure), adverse drug reactions, etc. can cause gastrointestinal discomfort.
When diarrhea, nausea and vomiting, it is recommended to go to the hospital to check the cause of the disease, according to the cause of the disease and actively cooperate with the doctor’s treatment.
