Introduction
In general, symptoms such as nausea, vomiting, diarrhea, abdominal pain, fever, and loss of appetite may indicate gastroenteritis. If you experience any of these symptoms, you should seek medical attention promptly. During an episode of gastroenteritis, it is also important to maintain adequate fluid intake and avoid consuming oily or hard-to-digest foods to aid in recovery.
Generally, gastrointestinal flu refers to the gastroenteric type of common cold. Symptoms such as nausea, vomiting, diarrhea, abdominal pain, fever, and loss of appetite may suggest gastroenteric flu. If the body experiences discomfort symptoms, prompt medical attention and treatment are recommended. Detailed analysis is as follows:
1. Nausea and Vomiting
Due to irritation of the gastrointestinal tract caused by virus or inflammation, the stomach muscles contract, and patients may frequently experience nausea accompanied by vomiting.
2. Diarrhea
After the intestines become infected, increased secretions impair absorption function, leading to excessive water content in the intestinal lumen. Coupled with increased intestinal motility, stools are typically loose or watery, possibly accompanied by abdominal cramps or bloating.
3. Abdominal Pain
Abdominal pain may occur due to inflammation of the gastrointestinal mucosa caused by viral infection. It usually presents as intermittent or dull abdominal pain, often localized around the navel.
4. Fever
After the virus enters the body, it triggers an inflammatory response, leading to elevated body temperature and fever. This typically manifests as a mild to moderate fever, with body temperature generally not exceeding 39°C.
5. Loss of Appetite
Affected by the illness, patients often lose interest in food and may have no appetite even for their favorite dishes. Some patients may also experience symptoms such as postprandial fullness, belching, and acid regurgitation.
During the course of gastroenteric flu, it is important to maintain adequate hydration and avoid consuming greasy or hard-to-digest foods to promote recovery.
