There are many causes of gastroenteritis, and whether it can be contagious depends mainly on the pathogen involved. For example, if gastroenteritis is caused by an infection with bacterial dysentery leading to gastrointestinal symptoms, this situation can be spread via the digestive tract and is contagious. However, if the gastroenteritis symptoms arise from exposure to air conditioning and getting a chill, this situation is not contagious. Therefore, patients with gastroenteritis must undergo routine blood and stool tests to identify the cause of the infection.

Which department should I go to for acute gastroenteritis?

Acute gastroenteritis should be treated in the gastroenterology department of the hospital. Acute gastroenteritis is mostly caused by unclean food or excessive fatigue, with the main symptoms being abdominal pain and diarrhea, accompanied by signs of dehydration in the body. Treatment mainly involves the use of antibiotics to control the infection and antidiarrheal medications to treat diarrhea. It is important to promptly replenish fluids and water if there is significant dehydration. During treatment, a light diet should be maintained, eating small meals frequently, and avoiding spicy, stimulating, and greasy foods. (Medication should be used under the guidance of a doctor.)

Symptoms of acute gastroenteritis caused by Norovirus

Symptoms of acute gastroenteritis due to norovirus infection primarily involve gastrointestinal dysfunction and infection. 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.

Can acute gastroenteritis cause shock?

Acute gastroenteritis, if it causes severe vomiting and frequent diarrhea, can lead to obvious dehydration and may cause shock. During shock, symptoms such as a drop in blood pressure, pale complexion, lethargy, and physical weakness appear, and timely fluid replenishment therapy is necessary. Additionally, proactive use of anti-inflammatory and anti-infection medications, as well as drugs that stabilize the intestines and stop diarrhea, can reduce symptoms of diarrhea. Moreover, during treatment, it is important to adjust the diet, eat smaller and more frequent meals, and consume more vegetables and fruits to supplement plant-based fibers.

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. (Please use medication under the guidance of a doctor.)

How many days does acute gastroenteritis last?

The course of acute gastroenteritis generally lasts about 7 to 10 days. Patients typically have an acute onset, presenting with abdominal discomfort, nausea, vomiting, and abnormal stools. The abdominal discomfort is usually centered around the navel or the lower abdomen, predominantly characterized by intermittent cramping pain. Vomiting usually occurs more severely after eating and generally involves expelling stomach contents, without accompanying hematemesis or bile, and recurs frequently. Abnormal stools commonly involve more frequent bowel movements, colloquially known as diarrhea. Along with an increase in stool frequency, the stool tends to be looser in texture, and some patients may have watery stools, thus typically it presents as an acute episode. General treatment involves diet adjustment and, when necessary, the addition of some oral medications. Generally, conditions gradually improve over about 7 to 10 days. (Please take medication under the guidance of a professional physician.)
