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 to avoid eating with gastroenteritis

Patients with gastroenteritis need to pay special attention to their diet, especially avoiding spicy, greasy, and irritating foods. They should also avoid strong tea and coffee, as these are necessary to abstain from. It is advisable to consume more bland or easily digestible foods, such as noodles, egg custard, and rice soup. Under strict dietary control, if symptoms do not improve, medication may be necessary. Common medications include those that suppress gastric acid secretion and protect the gastric mucosa, as well as antibiotics. (Please use medication under the guidance of a doctor.)

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.

acute gastroenteritis symptoms

Acute gastroenteritis caused by catching cold is due to viral infection. This condition often accompanies symptoms of upper respiratory tract infection and acute gastroenteritis, such as fever, chills, dizziness and weakness, generalized body ache, sore throat, and other symptoms of viral infection, along with abdominal pain, diarrhea, vomiting, and other gastrointestinal symptoms. The abdominal pain is usually not very pronounced, and the stool is mainly watery. Laboratory tests generally do not show significant abnormalities. Acute gastroenteritis caused by bacterial infection can also present with fever, chills, chills, abdominal pain, diarrhea, etc. The abdominal pain is often more pronounced and typically presents as episodic periumbilical pain. The stool characteristics are often mucous or jelly-like, and may even include pus and blood. Laboratory tests often show clear abnormalities, such as elevated white blood cells, pus cells in stool, white blood cells, or occult blood, etc.

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.

Why does acute gastroenteritis cause dizziness?

Acute gastroenteritis is characterized by symptoms such as vomiting, nausea, or diarrhea. If the diarrhea is severe, there can be significant bodily dehydration, manifesting as fatigue or dizziness. It is important to promptly replenish body fluids and undergo infusion therapy. At the same time, proactive use of antibiotics and antidiarrheal medications is advised. The general treatment period lasts 3-5 days. After recovery, attention should be given to dietary adjustments, incorporating fresh green vegetables. It is advisable to eat some fruit and have meals regularly and in controlled quantities, while reducing consumption of spicy, greasy, and irritating foods. Appropriate outdoor exercises should be performed to help regulate gastrointestinal function. (Please follow the doctor's advice regarding medication use.)
