Acute gastroenteritis is quite common in everyday life. If the symptoms are mild, the harm is not particularly great, and symptoms can include abdominal pain, diarrhea, and physical weakness. By using medication, recovery can generally be gradual over 2-3 days. If the symptoms are more severe, such as long-term recurrent diarrhea, it can lead to body dehydration, sunken eye sockets, dizziness, and headaches. Further dehydration can cause shock symptoms, such as decreased blood pressure and a thin pulse. It is necessary to visit a hospital in a timely manner, hydrate according to the type of dehydration, and treat with intestinal solidifiers, antidiarrheal, and antibiotic medications. (Please follow medical advice when using medications.)
