Acute gastroenteritis is common in summer and autumn, often caused by consuming unclean food. Consuming chilled watermelon or cola straight from the refrigerator can also trigger acute gastroenteritis. The primary symptoms include abdominal pain, diarrhea, nausea, and vomiting. Frequent diarrhea can lead to signs of dehydration in the body, such as sunken eyeballs and pale lips.

For acute gastroenteritis, immediate fluid replacement therapy should be administered, and antibiotics should be used to control the infection along with medications to stop diarrhea and firm up the stools.

What to do about acute gastroenteritis?

Acute gastroenteritis is considered to be caused by unclean food or bacterial and viral infections. It is important to actively provide symptomatic treatment. For nausea and vomiting, use antispasmodic and antiemetic medications; for repeated diarrhea and dehydration, use intestinal firming and antidiarrheal medications; for obvious bacterial infections, antibiotics should be used, preferably quinolones. Be sure to drink plenty of water and replenish fluids in a timely manner. During the acute phase, do not eat anything to avoid overburdening the gastrointestinal tract. After recovery, increase the consumption of vegetables to enhance nutrition and improve the body's resistance. (Please use medication under the guidance of a doctor.)

How many days to get an IV for acute gastroenteritis?

Acute gastroenteritis can be divided into bacterial enteritis and gastroenteric flu. When this condition occurs, it is first necessary to conduct relevant examinations such as routine blood tests, C-reactive protein, and routine stool tests. After identifying the specific cause, targeted treatment can be administered. Generally, for mild acute gastroenteritis, treatment can be achieved through oral medication. If symptoms of severe vomiting and diarrhea are present, and normal eating is impossible, then infusion therapy is required. As for the duration of infusion therapy, it depends on the specific situation; generally, if it is not very severe, a complete cure can be achieved in two to three days. If the inflammation is more severe, and the patient is elderly, weak, or has underlying diseases, the duration of infusion therapy may be appropriately extended.

The onset is usually sudden and often occurs in crowded places and communal dining settings. Symptoms include nausea, vomiting, abdominal pain, and diarrhea, with diarrhea being a common symptom. Children frequently exhibit vomiting, while adults are more likely to experience abdominal pain and diarrhea. Severe diarrhea can lead to dehydration, thus it is important to promptly replenish fluids and electrolytes to correct gastrointestinal dysfunction.

Causes of Acute Gastroenteritis

Acute gastroenteritis mostly occurs in summer and autumn, due to unhygienic eating habits and consumption of spoiled food. Additionally, a weak immune system or excessive fatigue can gradually lead to acute gastroenteritis. Therefore, it is important to prevent acute gastroenteritis by adopting a healthy lifestyle. This includes having meals regularly and in proper amounts, avoiding spoiled food, drinking plenty of water (preferably boiled water), ensuring the water is thoroughly boiled, maintaining a reasonable work-rest schedule, avoiding excessive fatigue, and eating less greasy and spicy food.
