Gastroenteritis

Gastroenteritis, commonly known as the stomach flu, is an infection or inflammation of the stomach and intestines, leading to symptoms such as diarrhea, vomiting, abdominal cramps, and fever. It is usually caused by viruses, bacteria, or parasites and spreads through contaminated food, water, or direct contact with an infected person.

Causes of Gastroenteritis

1. Viral Infections (Most Common)

   • Rotavirus – Common in infants and young children.

   • Norovirus – Highly contagious, often spreads in crowded places.

   • Adenovirus & Astrovirus – Affect children and immunocompromised individuals.

2. Bacterial Infections

   • Salmonella – Found in undercooked meat, eggs, and contaminated produce.

   • E. coli – Contaminated food or water.

   • Shigella – Spreads through poor hygiene.

   • Campylobacter – Found in raw poultry and unpasteurized dairy.

3. Parasitic Infections

   • Giardia lamblia – Contaminated water.

   • Cryptosporidium – Common in recreational water sources (pools, lakes).

4. Food Poisoning

   • Caused by consuming contaminated or spoiled food.

Symptoms of Gastroenteritis

• Watery diarrhea (may contain mucus or blood in bacterial infections).

• Nausea and vomiting.

• Abdominal cramps and bloating.

• Mild to high fever.

• Dehydration – Dry mouth, dizziness, reduced urination.

Diagnosis of Gastroenteritis

• Clinical evaluation based on symptoms.

• Stool tests – To detect bacteria, parasites, or viruses in severe cases.

• Blood tests – To check for dehydration or infection.

Treatment for Gastroenteritis

• Hydration is key – Drink plenty of fluids (oral rehydration solutions, water, clear broth).

• Rest and light diet – Eat bland foods like rice, toast, bananas, and applesauce.

• Medications

  • Antibiotics (only if a bacterial infection is confirmed).

  • Anti-nausea drugs (if vomiting is severe).

  • Probiotics – Help restore gut bacteria balance.

When to Seek Medical Help

• Severe dehydration (dry skin, confusion, very low urine output).

• Persistent vomiting or diarrhea lasting more than 3 days.

• High fever (above 102°F or 39°C).

• Bloody stools or severe abdominal pain.

Prevention of Gastroenteritis

• Practice good hygiene – Wash hands regularly with soap and water.

• Avoid contaminated food and water – Ensure proper food handling and drink safe, purified water.

• Vaccination – Rotavirus vaccine for infants helps prevent severe gastroenteritis.

• Proper sanitation – Keep kitchen surfaces clean and avoid cross-contamination.

Most cases of gastroenteritis are mild and resolve within a few days with proper rest and hydration. However, in severe cases, medical attention is necessary to prevent complications like severe dehydration and malnutrition.
