Gastroenteritis refers to a gut (intestine) infection where there is diarrhea (frequent passage of loose or watery stools). The infection is frequently accompanied by vomiting which typically lasts 6 to 24 hours. The diarrhea usually lasts 2 – 4 days. Other associated features are fever, tummy ache and loss of appetite. Majority of these infections are caused by viruses.

Food poisoning is when the child develops gastroenteritis after eating food contaminated with the virus or bacteria. He may also get infected when he shares a cup or utensils with someone who has the virus. Another way your toddler may have picked up the illness is by coming in contact with contaminated toys or infected fecal matter and then putting his/her hands in her mouth.

Gastroenteritis vs Food Poisoning

How To Manage

Majority will recover with adequate rest, fever management and maintain. If you are breastfeeding, do not stop. Feed your child for a shorter time and more often. Breast milk is the best liquid for your child. If your child is vomiting, use a teaspoon or syringe to give regular sips of liquid (commercially prepared oral rehydration solution which has the right proportion of glucose and electrolytes preferred).

Starchy foods such as bread, cereals, pasta, and rice, and fresh fruits and vegetables are the best foods to give your child in small quantity. There is no need to withhold milk or switch to a lactose-free formula (e.g. soy) unless the diarrhea is more than 4-5 days.

See a doctor if your child has any of the following WARNING SIGNS:

  • not willing to drink
  • no tears when crying
  • vomiting often for more than 4 to 6 hours
  • sunken eyes
  • more than 6 large, watery diarrheas in 1 day
  • stomach pain that is severe and does not stop
  • less than 5 wet diapers in a day
  • fast breathing
  • dry skin, mouth, and tongue
  • very sleepy or very fussy
  • cool or grayish skin
  • severe head or neck pain
  • green vomitus
  • blood in the vomit or diarrhea
  • bringing the knees up to stomach and crying (suggesting severe tummy ache)
  • fever over 39°C, or 102.2°F, for longer than 12 hours
  • sunken fontanelle (the soft spot on your child’s head if he or she is less than 18 months old)

Help to lower the chances of your child getting sick

  • Wash your hands after touching raw meat, chicken, or fish.
  • Keep meats that are not being eaten or cooked in the refrigerator.
  • Do not feed your child meats that are not cooked enough, particularly chicken and hamburger.
  • Throw away eggs with cracked shells. Do not feed your child raw eggs.
  • Use different cutting boards for raw meats and other foods.
  • Teach your child how to wash her hands thoroughly with soap and warm water after every bathroom visit and before meals or touching food.
  • help your child wash up every time she comes home from daycare, a play-date, or an outing

Prevent your child’s illness from spreading

  • Keep your child at home until the vomiting and diarrhea stops.
  • Ask all who enter your home to wash their hands after changing diapers or using the toilet, after your child vomits and before making and eating food.
  • Do not let anyone share eating utensils, such as forks, knives, spoons, and chopsticks, or toothbrushes or drinking cups. If your child puts toys in the mouth, do not let him or her share toys.
