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.

What department should I go to for acute gastroenteritis?

Symptoms such as abdominal pain, diarrhea, nausea, vomiting, and fever may indicate acute gastroenteritis. It is recommended to register for the Department of Gastroenterology, as acute gastroenteritis is primarily treated within this specialty. However, if the hospital does not have a Department of Gastroenterology, you can register for the Department of Internal Medicine for further examination and treatment. But if a large number of red blood cells, white blood cells, and pus cells are found in the stool, it is likely not acute gastroenteritis but bacterial dysentery, and it is advisable to register with the Department of Infectious Diseases or proceed to an infectious disease hospital for formal treatment.

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.)

Can I eat apples with acute gastroenteritis?

Apples are one of the essential fruits in our daily life, containing a rich array of nutrients, such as minerals, fruit acids, vitamins, fiber, etc., which are greatly beneficial to our human body. Acute gastroenteritis is usually caused by exposure to cold or improper diet, primarily characterized by symptoms such as abdominal pain, diarrhea, vomiting, and sometimes fever and chills. In this case, targeted treatment should be firstly applied, and the diet should consist mainly of light and easily digestible food, such as porridge and soft noodles, while avoiding raw, greasy, spicy foods, and alcoholic beverages. Apples are relatively cold in nature; it is best to avoid eating them raw under these circumstances. If there is a real desire to eat apples, steaming them before eating should be feasible.

Is acute gastroenteritis contagious?

Acute gastroenteritis is generally considered a self-limiting disease that is not contagious. The course of the disease is about a week, after which patients will gradually recover. Most patients with acute gastroenteritis have a history of unhygienic dietary practices, and the condition is caused by viral or bacterial infections. From a symptomatic perspective, the most obvious reasons for seeking medical advice are abdominal discomfort or abnormal stools. Abdominal discomfort can manifest as abdominal pain and bloating, with paroxysmal colic being relatively common in clinical practice. Of course, some patients also experience nausea and vomiting, with the vomit consisting of gastric contents and not accompanied by hematemesis, among other symptoms. Abnormal stools are often characterized by diarrhea, typically with an increased frequency of bowel movements, watery in nature, and possibly accompanied by bloody stools. The treatment of acute gastroenteritis generally focuses on symptomatic relief, including the consumption of easily digestible and clean foods. Treatment may include the use of gastroprotective agents, antispasmodics, and modifiers of the intestinal flora. Of course, if the patient has significant diarrhea, antidiarrheal medications may be added for symptomatic treatment.
