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.

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.)

Where to massage for acute gastroenteritis?

Acute gastroenteritis is a common clinical symptom, and we can usually alleviate this clinical symptom through massage. For the massage, we can choose some acupoints on the abdomen, such as Zhongwan, Xiawan, Liangqiu, and the Tianshu points beside the navel for massage. The massage technique should go from light to heavy. If it’s difficult to massage on the stomach, we can choose some acupoints on the distal limbs, including Zusanli, Liangqiu, Shang Juxu, and Xia Juxu, which are very good for relieving acute gastroenteritis. The duration for the massage at each acupoint is about 2-3 minutes. After the massage, we can further choose other acupoints based on differentiation; for example, if the person has excessive liver heat, the Taichong acupoint can be selected for massage to relieve some of the clinical symptoms of acute gastroenteritis.

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.

Acute gastroenteritis causes and symptoms

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.
