Gastrointestinal discomfort with fever symptoms should be specifically analyzed mainly according to the degree and type of fever, as well as the accompanying symptoms, which are generally common in acute gastroenteritis. Patients should immediately go to the hospital for relevant examinations to clarify the cause and then carry out symptomatic treatment. Common causes and treatment Acute gastroenteritis can be caused by diet, viral infection, bacterial infection and other factors, and can usually be accompanied by vomiting, diarrhea and other gastrointestinal symptoms. Under the guidance of professional doctors, antibiotics such as cephalosporin, norfloxacin, ciprofloxacin and other drugs should be used according to the relevant examination results, and montelukast can also be used for antidiarrheal treatment. If symptoms of dehydration occur, timely rehydration treatment is needed to prevent water and electrolyte imbalance. Patients also need to eat a light, easy-to-digest diet and drink warm water. Common tests Patients usually need to undergo stool routine, blood routine, blood biochemistry, protein test, and pathogenic examination. The stool routine can be used to make a preliminary determination of the cause of the disease based on stool characteristics, and the blood routine can be used to identify viral, bacterial or parasitic infections.
