Whole-body aches, fever of 38°C, and stomach upset—what's going on and what should I do?

Fever generally refers to elevated body temperature, and diarrhea is also known as loose bowels. Body aches, fever of 38°C, and diarrhea may be caused by factors such as excessive fatigue, improper diet, upper respiratory tract infection, gastroenteric flu, or acute enteritis. These conditions can usually be managed through adequate rest, dietary adjustments, and medication. If symptoms persist or worsen, prompt medical attention is recommended. Below is a detailed analysis:

1. Excessive Fatigue

After prolonged work or intense physical activity, the body may experience a stress response due to overexertion, leading to decreased immunity and dysfunction of the body's temperature regulation center, resulting in symptoms such as fever and muscle soreness. Diarrhea may result from digestive system disturbances caused by fatigue. It is advised to get proper rest, ensure sufficient sleep, avoid overexertion, and maintain good dietary hygiene and balanced nutrition.

2. Improper Diet

Consuming raw, cold, greasy, or spoiled food may irritate the gastrointestinal tract and lead to diarrhea. Poor dietary habits may also reduce immune function, increasing the risk of fever and body aches. It is recommended to adjust the diet by avoiding raw, cold, greasy, and spoiled foods, and instead opting for light, easily digestible meals.

3. Upper Respiratory Tract Infection

This is mostly caused by viral infections, though some cases may involve bacterial co-infections, which can also present with symptoms including body aches, fever, and diarrhea. If body temperature exceeds 38°C, antipyretic medications such as acetaminophen tablets or ibuprofen tablets may be taken under medical guidance. Additional treatments may include Pudilan Anti-inflammatory Oral Liquid or Oseltamivir Phosphate Granules.

4. Gastroenteric Flu

Typically caused by viral infections, this condition presents with body aches, fever up to 38°C, and diarrhea. Severe cases may lead to dehydration and electrolyte imbalances. Antiviral Oral Liquid, Lianhua Qingwen Capsules, or Ganmaoling Granules may be taken as directed by a physician. Patients with severe diarrhea may require intravenous fluid replacement therapy.

5. Acute Enteritis

Often linked to consuming contaminated food, patients may develop fever, generalized body aches, and diarrhea due to inflammatory stimulation. Diagnosis can be confirmed through routine stool tests at a hospital. Under medical supervision, patients may take antibiotics such as pipemidic acid tablets or levofloxacin capsules to combat infection, along with smectite powder for diarrhea control.

During treatment, patients should drink plenty of fluids or take lukewarm baths to help reduce fever. Bed rest is recommended during febrile periods. Eating fresh vegetables and fruits, as well as easily digestible foods like millet porridge and steamed egg custard, can support recovery.
