Gastrointestinal Symptoms with Mild Fever: Is It a Stomach Flu?

Slightly elevated body temperature and gastrointestinal discomfort?

Hello, I have had a slightly elevated body temperature of over 37.5°C in the past two days, and I experienced a fever up to 38.5°C.
I feel lethargic, have slight abdominal bloating, and am having difficulty with bowel movements, but I do not have a cough or runny nose.
I would like to know if this could be classified as a gastrointestinal flu? Thank you.

Hello! Gastrointestinal flu is a colloquial term that primarily refers to illnesses characterized by gastrointestinal discomfort.
It is advisable to review your travel history and exposure history.
If there is a risk of exposure or if your condition shows no signs of improvement, it is recommended that you seek medical attention for screening and treatment as soon as possible.
Additionally, for gastrointestinal discomfort, a light diet should be adopted.
Wishing you a speedy recovery.

More Info

When experiencing gastrointestinal symptoms accompanied by a mild fever, it is understandable to wonder if this could be a case of "stomach flu," which is commonly referred to as viral gastroenteritis. However, it's important to clarify that "stomach flu" is a colloquial term and does not refer to influenza, which primarily affects the respiratory system. Instead, viral gastroenteritis is an inflammation of the stomach and intestines caused by various viruses, leading to symptoms such as diarrhea, vomiting, abdominal cramps, and fever.

In your case, you mentioned having a slight fever (ranging from 37.5°C to 38.5°C), a feeling of lethargy, mild abdominal bloating, and difficulty with bowel movements, but no respiratory symptoms like coughing or a runny nose. These symptoms could indeed suggest a gastrointestinal issue, but they do not definitively indicate viral gastroenteritis.
Several factors could contribute to your symptoms. For instance, dietary choices, such as consuming raw fish, steak, or hot pot, could lead to foodborne illnesses, which can present with similar symptoms. Additionally, gastrointestinal discomfort can arise from other conditions, including gastritis, peptic ulcers, or even stress-related gastrointestinal disturbances.
Given the absence of severe symptoms like persistent vomiting, diarrhea, or significant abdominal pain, your condition may not be severe at this moment. However, the presence of a fever and gastrointestinal discomfort warrants attention. It is advisable to monitor your symptoms closely. If your fever persists, or if you experience worsening symptoms such as severe abdominal pain, persistent vomiting, or signs of dehydration (such as dry mouth, decreased urination, or dizziness), seeking medical attention would be prudent.

In the meantime, consider adopting a bland diet that avoids spicy, fatty, or acidic foods, which could further irritate your gastrointestinal tract. Staying hydrated is crucial, so drink plenty of fluids, preferably water or electrolyte solutions, to maintain hydration levels. Over-the-counter medications like antacids may help alleviate discomfort, but it is essential to consult a healthcare professional before starting any medication, especially if you have underlying health conditions or are taking other medications.

In summary, while your symptoms could suggest a mild gastrointestinal issue, they do not definitively indicate viral gastroenteritis. It is essential to monitor your condition and seek medical advice if symptoms worsen or do not improve. Your health is paramount, and early intervention can often lead to better outcomes.
