The sudden appearance of abdominal pain, false sweating and dizziness should be considered clinically as triggered by acute gastroenteritis first. Dizziness, sweating and blackness in front of the eyes are symptoms caused by increased reflex vagal excitability after abdominal pain. If there are clinical symptoms such as increased defecation, stool mucus, intestinal tinnitus and abdominal distension, it is even more corroborative of acute gastroenteritis. It is recommended to check blood routine, stool routine, abdominal ultrasound, and also routine blood pressure and electrocardiogram, to jointly clarify the cause and choose the appropriate treatment plan according to the cause.
