Gastroenteritis (Stomach Flu)

Stomach flu (viral gastroenteritis) is caused by viruses like norovirus or rotavirus and typically develops gradually over 12-48 hours after exposure. Food poisoning is caused by consuming contaminated food or water and usually causes symptoms within hours of eating. Both can cause similar symptoms including nausea, vomiting, and diarrhea. Our medical providers can help determine the likely cause based on your symptom timeline, recent exposures, and clinical presentation to guide appropriate treatment.

Most cases of gastroenteritis are viral and do not require antibiotics. According to medical guidelines, antibiotics are only appropriate for bacterial infections confirmed through testing. Our providers may recommend stool testing if your symptoms suggest bacterial gastroenteritis, such as high fever, bloody diarrhea, or recent travel to high-risk areas. Unnecessary antibiotic use can worsen diarrhea and contribute to antibiotic resistance, so proper diagnosis is essential.

IV hydration therapy is recommended when you cannot keep oral fluids down, show signs of moderate to severe dehydration (dizziness, decreased urination, rapid heart rate, dry mouth), or have been vomiting for more than 12-24 hours. Our medical providers assess your hydration status through physical examination and vital signs. IV fluids work rapidly to restore fluid balance and often provide significant relief within the treatment session, allowing you to transition back to oral hydration.

Yes, viral gastroenteritis is highly contagious and spreads through close contact with infected individuals, contaminated surfaces, or consuming contaminated food or water. According to the CDC, norovirus can spread easily in households, schools, and healthcare settings. You remain contagious for at least 48 hours after symptoms resolve. Practice strict hand hygiene, avoid preparing food for others, and disinfect contaminated surfaces with bleach-based cleaners to prevent transmission.

Start with clear liquids like water, clear broth, or oral rehydration solutions to prevent dehydration. Once vomiting subsides, gradually introduce bland foods following the BRAT diet: bananas, rice, applesauce, and toast. Add other bland foods like crackers, plain pasta, and boiled potatoes as tolerated. Avoid dairy products, caffeine, alcohol, fatty foods, and spicy foods until fully recovered. Small, frequent sips and meals are better tolerated than large amounts at once.

No appointment is necessary. We welcome walk-ins daily from 8am to 8pm at both our Palm Beach Gardens and Stuart locations. We understand that gastroenteritis symptoms can be severe and uncomfortable, so we prioritize getting you evaluated and treated promptly. Bring your photo ID, insurance card, and a list of current medications to help us provide safe, effective care.

Visit the emergency room immediately if you experience severe dehydration with confusion or inability to stand, severe abdominal pain that doesn't improve, bloody vomit or black tarry stools, signs of shock (rapid heartbeat, cold skin, rapid breathing), or inability to keep any fluids down for 24+ hours. For typical gastroenteritis symptoms with mild to moderate dehydration, urgent care provides appropriate evaluation and treatment including IV hydration therapy.

Practice rigorous hand hygiene by washing hands with soap and water for at least 20 seconds, especially after using the bathroom and before eating. Alcohol-based hand sanitizers are less effective against norovirus. Disinfect contaminated surfaces with bleach-based cleaners. Avoid preparing food for others for at least 48 hours after symptoms resolve. Wash contaminated clothing and linens separately in hot water. Avoid close contact with family members when possible during the acute illness phase.
