Acute Gastroenteritis
What are the symptoms of acute gastroenteritis?
Acute gastroenteritis is one of the common diseases in gastroenterology, especially prevalent in the summer and autumn seasons. It is usually caused by exposure to cold or contaminated food. The main symptoms include abdominal pain, vomiting, and diarrhea. Depending on the cause, symptoms can vary; for instance, a viral infection causing gastroenteric flu often accompanies symptoms such as dizziness, headache, fatigue, body aches, sore throat, or fever. Infections caused by contaminated food often lead to abdominal pain and diarrhea, with stools frequently appearing mucous or containing blood and pus. Lab tests often show an elevated white blood cell count.
Is acute gastroenteritis serious?
Acute gastroenteritis is quite severe, as it can cause significant vomiting and diarrhea. Severe diarrhea can lead to symptoms of dehydration. Additionally, acute gastroenteritis can lead to decreased appetite, weight loss, and lethargy, affecting normal life and work. For acute gastroenteritis, treatment primarily involves medication, mainly antibiotics and antidiarrheal drugs. During treatment, it is recommended to eat smaller, more frequent meals. For severe diarrhea, it is advisable to refrain from eating and rely mainly on intravenous fluids for nutrition. Moreover, meals should be regular and controlled in quantity, avoiding overly spicy or greasy foods. (Medication should be used under the guidance of a doctor.)
What is acute gastroenteritis?
Acute gastroenteritis often has a history of consuming unclean food, with an incubation period that usually ranges from several hours to several days, most commonly one to two days. The onset of acute gastroenteritis is typically characterized by abdominal pain, diarrhea, urgent and increased bowel movements, nausea, vomiting, fever, and even convulsions. The frequency of bowel movements may increase to 10-30 times a day, and the patient may experience mild fever among other symptoms. Severe diarrhea can be accompanied by stools containing pus and blood, along with vomiting. In severe cases, patients may also experience dehydration and even shock. Therefore, patients with acute gastroenteritis should try to replenish energy, avoid exacerbation of the illness due to electrolyte imbalance, and prevent severe dehydration.
What to eat for acute gastroenteritis
Acute gastroenteritis is particularly common in clinical practice, and its treatment in gastroenterology and emergency departments generally involves two steps. The first step is general treatment, where patients are advised to rest, eat easily digestible, liquid foods such as thin porridge and rice soup, and avoid spicy and irritating foods, such as chili peppers. The second step, if dietary treatment is not effective, involves the use of specific medications. For abdominal pain, pain relievers can be used, and for diarrhea, medications to stop diarrhea and regulate the intestinal flora can be used. Of course, the symptoms of acute gastroenteritis are varied, including abdominal pain, diarrhea, nausea, vomiting, and even fever. Therefore, if there is fever, it is generally recommended to take some antibiotics orally. If there is only diarrhea, it is only necessary to take medications to stop the bleeding and regulate the intestinal flora, and there is no need for anti-inflammatory drugs. Thus, the treatment plans vary depending on the different diseases and symptoms, but all medications should be used under the guidance of a doctor.
What to do about acute gastroenteritis?
Acute gastroenteritis is considered to be caused by unclean food or bacterial and viral infections. It is important to actively provide symptomatic treatment. For nausea and vomiting, use antispasmodic and antiemetic medications; for repeated diarrhea and dehydration, use intestinal firming and antidiarrheal medications; for obvious bacterial infections, antibiotics should be used, preferably quinolones. Be sure to drink plenty of water and replenish fluids in a timely manner. During the acute phase, do not eat anything to avoid overburdening the gastrointestinal tract. After recovery, increase the consumption of vegetables to enhance nutrition and improve the body's resistance. (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.
Can acute gastroenteritis cause shock?
Acute gastroenteritis often manifests as symptoms such as vomiting, abdominal pain, and diarrhea, sometimes accompanied by fever, dizziness, fatigue, etc., often caused by factors such as exposure to cold or improper diet. These include what we refer to as viral enteritis and bacterial enteritis. In most cases, symptoms gradually alleviate after symptomatic treatment, and some may improve without treatment. However, a few patients, such as those with uncontrollable vomiting and diarrhea, coupled with an inability to eat, may experience worsening dizziness, significant fatigue, dry mouth, poor skin elasticity, and reduced urine output. These symptoms indicate the development of hypovolemic shock, which requires attention.
Causes of Acute Gastroenteritis
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.
How to treat gastroenteritis?
The treatment of gastroenteritis primarily depends on the cause and specific symptoms to determine the treatment plan. Exposure to cold or improper diet may cause acute gastroenteritis. In such cases, it is recommended to first check routine blood tests, C-reactive protein, stool routine, etc., to identify the cause. Gastroenteric flu can be treated with antiviral drugs and astringent antidiarrheal medications to achieve satisfactory results. Infectious diarrhea caused by bacterial infection generally uses antimicrobial drugs combined with antidiarrheal medications to also achieve satisfactory effects. Commonly used drugs include cephalosporins or quinolones anti-inflammatory. At the same time, it is important to pay attention to a light and easily digestible diet, and if diarrhea is severe, infusion treatment may be necessary to prevent dehydration.
What should I do about acute gastroenteritis?
Acute gastroenteritis typically presents with symptoms such as abdominal pain, diarrhea, and vomiting, and sometimes accompanied by fever and chills. In such cases, it is important to rest, keep warm, avoid cold, and follow a diet that is light and easy to digest, such as rice porridge, soft noodles, etc. It is advisable to avoid raw, greasy, spicy, and alcoholic foods. Treatment should be based on the specific cause. For viral infections causing gastroenteric flu, antiviral and antidiarrheal astringents are commonly used. For bacterial infections causing infectious diarrhea, antibacterial and antidiarrheal treatments are needed, typically involving cephalosporins or quinolones. Generally, symptoms will gradually ease.
