Enteritis is divided into acute enteritis and chronic enteritis. The main symptoms of acute enteritis include abdominal pain, diarrhea, fever, etc., and blood tests may show an increase in white blood cells and neutrophils. The treatment mainly focuses on anti-inflammatory drugs, hydration, and antidiarrheal therapies. Generally, recovery can be achieved within a week. The main symptoms of chronic enteritis include abdominal pain, diarrhea, or constipation. Colonoscopy can reveal changes in the intestinal mucosa such as hyperemia, edema, erosion, and mucus attachment, which can diagnose chronic enteritis. In terms of treatment, Western medicine primarily involves the oral administration of probiotics to adjust the gut microbiota. It can also be combined with traditional Chinese medicine based on syndrome differentiation. Integrating Chinese and Western medicine can enhance treatment effectiveness. Additionally, the diet should primarily consist of light and easily digestible foods.

What should I do about acute enteritis?

What should be done if one suffers from acute gastroenteritis? In general treatment, the first step is to eliminate the cause, discarding some unclean food that led to the illness; Secondly, rest appropriately according to the condition, with bed rest for severe cases; Thirdly, patients with severe vomiting and diarrhea should temporarily fast, and gradually introduce some light, easy-to-digest foods as the condition improves; Fourthly, it is advocated to use oral rehydration and salt supplementation to replenish the body fluids lost due to vomiting and diarrhea. Fifthly, keep the abdomen moderately warm; record the frequency and characteristics of the stool; accurately record the amount of urine, paying attention to these aspects. In terms of medication treatment: This includes controlling intra- and extra-intestinal infections and medications that protect the gastric mucosa, as well as treatments involving microecological preparations. The third aspect is to correct dehydration and electrolyte imbalance: during the initial stages of diarrhea, at home, one can use some rice soup, or add a bit of sugar and salt, alternating with plain water and sugar to prevent dehydration. For mild or moderate dehydration, if the patient does not have vomiting or abdominal distension, oral rehydration solutions may be sufficient. In cases of severe dehydration or when the overall condition is poor, indicating potassium, sodium, chloride electrolyte imbalances, and acidosis, intravenous fluid therapy in a hospital is necessary. It is also important to note that both oral rehydration solutions and oral medications should be used correctly under the guidance of a doctor, and should not be taken without professional advice.

Is it useful to take probiotics for enteritis?

Some patients may ask if probiotics are useful for enteritis. A large number of studies have shown that dysbiosis of the gut microbiota can cause enteritis, and patients with enteritis generally experience a disruption of the gut microbiota, especially those who have had the condition for a longer period, often have this situation of gut microbiota imbalance. Therefore, appropriately taking probiotics should be beneficial for the recovery of the gut, because probiotics inhibit the growth of harmful bacteria in the gut, adhere to the intestinal mucosa to form a protective layer, and prevent attacks on the intestinal mucosa by harmful microbiomes. Additionally, probiotics can produce various enzymes involved in the digestion of food in the gut and other physiological processes; moreover, probiotics can also regulate the activity of immune factors in the gut, enhancing intestinal immunity. Thus, probiotics play a very positive role in preventing and treating symptoms that arise from enteritis. However, patients with enteritis also need to supplement appropriate probiotics under the guidance of a doctor, choosing probiotics that meet the different needs of different individuals to improve related symptoms.

How to treat enteritis in children

How to treat enteritis in children? First, it is necessary to assess whether the enteritis is caused by a virus or a bacterial infection. If it is simply viral enteritis, the first step generally involves rehydration, which can be provided through oral rehydration salts to replenish fluids and electrolytes. Additionally, probiotics such as Bifidobacterium or Lactobacillus acidophilus can be given to regulate the intestinal flora, and smectite can be used to protect the gastrointestinal mucosa. If it is viral diarrhea, antiviral medications can also be added to the treatment. If the diarrhea is considered to be caused by a bacterial infection in the intestines, some antibiotics can be administered orally, including cephalosporins or penicillin antibiotics. If the infection is severe, intravenous therapy may be necessary.

What to do if enteritis causes a fever?

Some patients with enteritis will develop fever as a complication. In treating the complication of fever in enteritis, we should actively treat it based on the cause of enteritis and manage the fever symptomatically. To reduce fever in enteritis, we can first use physical cooling methods, such as turning on the air conditioning, lowering the room temperature, or wearing less clothing. It is important to protect the abdomen from getting cold during this time. When the fever is severe, it is advisable to replenish with saline solutions, etc., to improve dehydration and balance electrolyte disturbances. It is also important to seek medical attention in a timely manner and to undergo treatment under the guidance of a doctor. For individuals who are suitable for antibiotic treatment, antibiotics should be administered based on the specific needs of the condition, and the treatment should include fever reduction, heat clearing, and anti-inflammatory measures according to the specific clinical situation.
