Acute Diarrhea and Vomiting: Gastroenteritis Symptoms Causes Guide
Summary
Gastroenteritis, often called the "stomach flu," is a common condition that affects your stomach and intestines. It's usually caused by a virus, leading to symptoms like diarrhea, vomiting, and stomach cramps. Most cases are mild and resolve in 24-48 hours. The main concern is dehydration, so staying hydrated is crucial. This handout will guide you on managing symptoms, knowing what's normal, and when to seek medical help.
What Is This & Why It Matters
Gastroenteritis is an inflammation of the stomach and intestines. It's often caused by viruses, but can also be due to bacteria or food poisoning. Symptoms include diarrhea, vomiting, nausea, and stomach cramps. While unpleasant, it's typically not serious. The condition often spreads through contact with infected people or contaminated food and water. Practicing good hygiene can help prevent its spread.
What You Should Do
- Drink plenty of fluids to stay hydrated; water, broth, or oral rehydration solutions are best.
- Eat small, light meals as tolerated; foods like bananas, rice, applesauce, and toast can be soothing.
- Wash your hands frequently with soap and water to prevent spreading germs.
- Rest as much as possible; your body needs energy to fight the infection.
- Monitor urine output; it should be light in color if you're well-hydrated.
- Use over-the-counter medications like acetaminophen for fever or aches if needed.
What You Should NOT Do
- Do not drink alcohol or caffeinated beverages as they can dehydrate you further.
- Avoid dairy products until you feel better; they can make symptoms worse.
- Don't eat spicy or fatty foods; these can irritate your stomach.
- Do not ignore signs of dehydration such as dark urine or dizziness.
- Avoid sharing utensils or towels with others to prevent spreading the infection.
