The main treatment methods for acute gastroenteritis are as follows.

Firstly, the patient should rest in bed. If the patient has persistent vomiting, or shows signs of dehydration caused by vomiting, it is necessary to promptly rehydrate the patient. Regarding the diet, it is advisable for the patient to consume liquid or semi-liquid foods, such as porridge and rice soup, to prevent dehydration.

Secondly, it is crucial to treat the symptoms. If the patient has uncontrollable vomiting, we can administer antiemetic medications to alleviate this symptom.

Thirdly, in the case of antimicrobial treatment, common gastroenteritis may involve bacterial infections, which require antibiotics for targeted treatment of infectious diarrhea. However, it is important to avoid overuse or misuse of these antimicrobial drugs.

Furthermore, attention must be paid to dietary habits. It is essential to wash hands before meals and after using the toilet, and to properly disinfect raw vegetables, fruits, and meats, which should be thoroughly cooked before consumption, to effectively prevent the occurrence of gastroenteritis.

How to treat acute gastroenteritis?

The main principles of treating acute gastroenteritis clinically are to stop vomiting, stop diarrhea, relieve spasms, replenish fluids, and rest in bed symptomatically. For mild cases, oral intake of dilute salt water can be used to replenish lost body fluids. If there is frequent vomiting or obvious dehydration, intravenous fluids are necessary to maintain water and electrolyte balance. Sensitive antibiotics should be used to treat intestinal inflammation, but it is important to prevent antibiotic abuse. With active treatment, the prognosis for acute gastroenteritis is generally good. After treatment, attention should also be paid to diet; avoid eating unclean food, and consume less raw, cold, and spicy foods, while also paying attention to personal prevention.

What tests are done for chronic gastritis?

Chronic gastroenteritis is a chronic inflammation that occurs in the mucous membrane of the gastrointestinal tract. The basic pathological change is the infiltration of a large number of neutrophils or lymphocytes in the mucosa. Examinations mainly include endoscopy and routine stool tests. Gastroscope and colonoscopy can be used to assess the extent of mucosal lesions in the gastrointestinal tract, and routine stool tests can determine the presence of occult blood positivity. If there is blood in the stool, a routine blood test can also be conducted to check for chronic blood loss anemia. Based on the results of these examinations, the severity of the lesions can be understood, and appropriate medications can be actively chosen for symptomatic treatment.

The difference between a stomach cold and gastroenteritis

Gastrointestinal colds and gastroenteritis generally have similar symptoms. Gastrointestinal colds are caused by viral infections or heatstroke, causing mild fever, runny nose, mild nausea, diarrhea, etc., typically without substantive white blood cells or pathogens in the stool. Gastroenteritis, on the other hand, involves actual pathological changes in the gastrointestinal tract, such as from Helicobacter pylori or E. coli infections, and usually does not cause fever, runny nose, or other complications. Typical symptoms include intermittent abdominal pain, diarrhea, nausea, vomiting, and other digestive system symptoms.

How to completely cure acute gastroenteritis?

Acute gastroenteritis generally occurs more frequently in the summer and autumn seasons, possibly due to exposure to cold or improper diet, typically presenting with symptoms such as abdominal pain, diarrhea, vomiting, bloating, and even fever and chills. Relevant tests, such as a complete blood count, C-reactive protein, and stool examination, can usually confirm the diagnosis. As for treatment, it depends on the cause, such as anti-inflammatory, antiviral, antidiarrheal, and rehydration measures. Most cases of acute gastroenteritis can be completely cured. During treatment, it's necessary to control the diet by consuming light, easily digestible foods, such as porridge and soft noodles, and to avoid raw, greasy, or spicy foods that might provoke recurring episodes. (Specific medications should be used under the guidance of a doctor.)
