Stomach flu vomiting fever in kids is often caused by viral gastroenteritis. Parents commonly search for help when a baby is vomiting with fever from stomach flu, a toddler has vomiting and fever from a stomach bug, or a child seems suddenly sick and unable to keep much down. In many cases, vomiting starts first or around the same time as the fever, and symptoms improve with rest and careful fluids. The biggest concern is usually dehydration, especially in younger children who are vomiting often or refusing to drink.
A child vomiting with fever from stomach flu may throw up several times over a few hours and also feel warm, tired, or achy.
Many kids with a stomach virus also develop diarrhea, belly pain, or little interest in food for a day or two.
Children often seem less active than usual, but may still take small sips, rest, and gradually improve as the virus passes.
Try tiny sips of water, oral rehydration solution, or other fluids your child usually tolerates. Small amounts given often are usually easier to keep down.
If your kid is vomiting and has fever from stomach flu, focus on fluids first. Once vomiting slows, you can reintroduce simple foods as tolerated.
Pay attention to wet diapers, bathroom trips, tears, dry mouth, and whether your child is becoming more alert or more listless over time.
Call if your child has very little urine, a dry mouth, no tears, sunken eyes, unusual sleepiness, or cannot keep fluids down.
If you are wondering how long vomiting with fever lasts with stomach flu, ongoing vomiting, worsening fever, or no improvement after a day or two deserves medical advice.
Seek care sooner for severe belly pain, trouble waking your child, breathing concerns, blood in vomit or stool, or symptoms that improved and then got worse again.
Vomiting from a stomach virus often improves within about 24 hours, while fever and low energy can last a bit longer. If vomiting continues, your child cannot keep fluids down, or symptoms are getting worse instead of better, it is a good idea to contact a doctor.
Start with small, frequent sips of fluid and let your toddler rest. Avoid pushing large drinks or heavy meals right away. The main goal is preventing dehydration and watching for changes in alertness, urine output, and ability to keep fluids down.
Stomach flu often causes vomiting, fever, reduced appetite, stomach cramps, and sometimes diarrhea. It usually spreads through a household or daycare and comes on fairly quickly. Because other illnesses can also cause vomiting and fever, it helps to look at the full symptom pattern and how your child is acting overall.
Call if your child shows signs of dehydration, has severe pain, is hard to wake, has a high or persistent fever, is vomiting repeatedly without keeping fluids down, or seems to improve and then suddenly gets worse again.
