Introduction
For mild acute gastroenteritis, such as gastroenteritis caused by mild food poisoning or viral infection, most patients can recover within 3 to 7 days through adequate rest, hydration with fluids and electrolytes, and following a bland diet. During this period, avoiding greasy, spicy, and hard-to-digest foods can help accelerate the recovery process of the gastrointestinal tract.

Gastroenteritis generally refers to acute gastroenteritis. If the condition is mild, it usually takes 3-7 days for a full recovery. If the illness is more severe, it may take 7-14 days to recover. The specific duration may vary. If experiencing any discomfort symptoms, it is recommended to seek medical attention at a hospital as soon as possible and follow the doctor's instructions for treatment.

For mild cases of acute gastroenteritis, such as those caused by mild food poisoning or viral infections, most patients can recover within 3-7 days through adequate rest, hydration, electrolyte replacement, and following a bland diet. During this period, avoiding greasy, spicy, and hard-to-digest foods can help accelerate the recovery process.

Severe acute gastroenteritis caused by highly pathogenic bacteria or viruses can lead to frequent vomiting, more than 10 episodes of diarrhea per day, accompanied by high fever, dehydration, and electrolyte imbalance. Medical treatment including anti-infective therapy, antiemetics, antidiarrheals, and fluid replacement may be necessary. The overall recovery time may take 7-14 days.

During the recovery period, choose bland and easily digestible foods such as congee and noodles. Avoid greasy, spicy, and high-fiber foods that are difficult to digest in order to prevent additional strain on the gastrointestinal system.
