Gastroenteritis: First aid

Treatment

Adult

  • Sip liquids. Sip a sports drink or water to prevent dehydration. Drinking fluids too quickly can make nausea and vomiting worse. Take small sips often over a couple of hours, instead of drinking a large amount at once.
  • Take note of urination. You should be urinating at regular intervals, and your urine should be light and clear. Infrequent passage of dark urine is a sign of dehydration. Dizziness and lightheadedness also are symptoms of dehydration. If any of these symptoms occur and you can't drink enough fluids, seek medical attention.
  • Ease back into eating. Try to eat small amounts of food frequently if you experience nausea. Otherwise, slowly begin to eat bland, easy-to-digest foods, such as soda crackers, toast, gelatin, bananas, applesauce, rice and chicken. Stop eating if your nausea returns. Avoid milk and dairy products, caffeine, alcohol, nicotine, and fatty or highly seasoned foods for a few days.
  • Get plenty of rest. The illness and dehydration can make you weak and tired.

Child

  • Encourage your child to rest.
  • Offer fluids. When your child's vomiting stops, begin to offer small amounts of an oral rehydration solution (Ceralyte, Enfalyte, Pedialyte). Don't use only water or only apple juice. Drinking fluids too quickly can worsen the nausea and vomiting, so try to give small frequent sips over a couple of hours, instead of drinking a large amount at once. Try using a water dropper of rehydration solution instead of a bottle or cup.
  • Introduce bland foods. Gradually introduce bland, easy-to-digest foods, such as toast, rice, bananas and potatoes. Avoid giving your child full-fat dairy products, such as whole milk and ice cream, and sugary foods, such as sodas and candy. These can make diarrhea worse.
  • Breastfeed or bottle-feed. If you're breastfeeding, let your baby nurse. If your baby is bottle-fed, offer a small amount of an oral rehydration solution or regular formula.
