Vomiting with diarrhea

Definition:

* Vomiting is the forceful emptying (throwing up) of a large portion of the stomach’s contents through the mouth

* Nausea and abdominal discomfort usually precede each bout of vomiting

* Vomiting and diarrhea together is covered by this topic

Causes:

* Main Cause: Stomach and intestinal infection (gastroenteritis) from a stomach virus (eg, rotavirus). The illness starts with vomiting but diarrhea usually follows within 12 to 24 hours.

* Food poisoning from toxins produced by bacteria growing in poorly refrigerated foods (eg, Staphylococcus toxin in egg salad, Bacillus cereus toxin in rice dishes).

Severity of Vomiting:

The following is an arbitrary attempt to classify vomiting by risk for dehydration:

* Mild: 1 to 2 times a day

* Moderate: 3 to 7 times a day

* Severe: Vomits everything or nearly everything, or 8 or more times a day

* Severity relates even more to the length of time that the particular severity level has persisted. At the beginning of a vomiting illness (especially following food poisoning), it’s common for a child to vomit everything for 3 or 4 hours and then become stable with   mild or moderate vomiting.

* Watery stools in combination with vomiting carry the greatest risk for causing dehydration

* The younger the child, the greater the risk for dehydration

How to Recognize Dehydration:

* Dehydration means that the body has lost excessive fluids, usually from vomiting or diarrhea. An associated weight loss of more than 3% is required. In general, mild diarrhea, mild vomiting, or a mild decrease in fluid intake does not cause dehydration.

* Dehydration is the most important complication of diarrhea

* The following are signs of dehydration:

– Decreased urination (no urine in more than 8 hours) occurs early in the process of dehydration. So does a dark-yellow, concentrated yellow. If the urine is light straw colored, your child is not dehydrated.

– Dry tongue and inside of the mouth. Dry lips are not helpful.

– Dry eyes with decreased or absent tears

– In infants, a depressed or sunken soft spot

– Delayed capillary refill longer than 2 seconds. This refers to the return of a pink color to the thumbnail after you press it and make it pale. Ask your child’s doctor to teach you how to do this test.

– Irritable, tired out, or acting ill. If your child is alert, happy, and playful, he is not dehydrated.

– A child with severe dehydration becomes too weak to stand or very dizzy if he tries to stand.

Home Care Advice for Vomiting with Diarrhea:

1. Reassurance:

* Most vomiting is caused by a viral infection of the stomach and intestines or by food poisoning

* Vomiting is the body’s way of protecting the lower intestinal tract

* When vomiting and diarrhea occur together, treat the vomiting. Don’t do anything special for the diarrhea

2. For Bottle-fed Infants, Offer Oral Rehydration Solution (ORS) for 8 Hours:

* ORS (eg, Pedialyte, store brand) is a special electrolyte solution that can prevent dehydration. It’s readily available in supermarkets and drugstores.

* For vomiting once, continue regular formula

* For vomiting more than once, offer ORS for 8 hours. If ORS is not available, use formula.

* Spoon or syringe feed small amounts of ORS —1 to 2 teaspoons (5 to 10 mL) every 5 minutes.

* After 4 hours without vomiting, double the amount

* After 8 hours without vomiting, return to regular formula

* For infants older than 4 months, also return to cereal and strained bananas

* Return to normal diet in 24 to 48 hours

3. For Breastfed Infants, Reduce the Amount Per Feeding:

* If infant vomits once, nurse 1 side every 1 to 2 hours

* If infant vomits more than once, nurse for 5 minutes every 30 to 60 minutes. After 4 hours without vomiting, return to regular breastfeeding.

* If infant continues to vomit, switch to ORS (eg, Pedialyte) for 4 hours

* Spoon or syringe feed small amounts of ORS —1 to 2 teaspoons (5 to 10 mL) every 5 minutes.

* After 4 hours without vomiting, return to regular breastfeeding. Start with small feedings of 5 minutes every 30 minutes and increase as tolerated.

4. For Older Children (Older Than 1 Year), Offer Small Amounts of Clear Fluids for 8 Hours:

* ORS: Vomiting with watery diarrhea needs ORS (eg, Pedialyte). If child refuses ORS, use half-strength Gatorade.

* Give small amounts—2 to 3 teaspoons (10 to 15 mL) every 5 minutes

* After 4 hours without vomiting, increase the amount

* After 8 hours without vomiting, return to regular fluids

* Solids: After 8 hours without vomiting, add solids

– Limit solids to bland foods. Starchy foods are easiest to digest

– Start with saltine crackers, white bread, cereals, rice, and mashed potatoes

– Return to normal diet in 24 to 48 hours.

5. Avoid Medicines:

* Discontinue all nonessential medicines for 8 hours (Reason: usually make vomiting worse)

* Fever: Fevers usually don’t need any medicine. For higher fevers, consider acetaminophen (eg, Tylenol) suppositories. Never give oral ibuprofen (eg, Advil); it is a stomach irritant

* Call your doctor if your child is vomiting an essential medicine

6. Contagiousness: Your child can return to child care or school after vomiting and fever are gone.

7. Expected Course: Moderate vomiting usually stops in 12 to 24  hours. Mild vomiting (1 to 2 times a day) with diarrhea can continue intermittently for up to a week.

8. Call Your Doctor If:

* Vomiting becomes severe (vomits everything) longer than  8 hours

* Vomiting persists longer than 24 hours

* Signs of dehydration

* Diarrhea becomes severe

* Your child becomes worse
