A stomach bug is one of the most common reasons New Yorkers look for at-home care. Here is how to manage it effectively, prevent it spreading, and recognize when to call for a licensed medical clinician.
Quick answer
Prioritize hydration, rest, and isolation. Most cases improve within 1–3 days, but dehydration can develop quickly and requires evaluation.
Symptoms and timelines
A stomach bug typically starts with nausea, then progresses to vomiting, diarrhea, or both. Incubation after exposure is usually 12–48 hours. Symptoms often peak within the first 24 hours and improve steadily over 1–3 days. Maintaining hydration during this period is the most important factor in preventing complications.
What to do at home in the first 6 hours
- Begin small, frequent sips of an oral rehydration solution immediately
- Pause solid food while vomiting is active
- Rest as much as possible
- Avoid preparing food for household members
- Disinfect shared surfaces with a bleach-based cleaner
What to eat and drink
Start with oral rehydration solution, water in small sips, and clear broth. Once vomiting has settled, reintroduce bland foods gradually — crackers, toast, plain rice. Avoid alcohol, dairy, greasy foods, and caffeine until you have fully recovered.
How it spreads in NYC households
Stomach bugs spread through contaminated hands, surfaces, and shared items. Wash hands with soap and water frequently. Use bleach-based disinfectants on bathroom surfaces and high-touch areas. Wash linens and towels on a hot cycle. Avoid sharing utensils, glasses, or towels.
When to get evaluated
Get same-day evaluation from a licensed medical clinician if you cannot keep any fluids down for more than 8 hours, if you notice dehydration signs (dizziness, very dark urine, dry mouth, rapid heartbeat), if you have severe abdominal pain, blood in your stool, or a high fever. Norovirus in NYC is a common cause of stomach bug symptoms. Request a house call or call (212) 742-5329.
