Nausea and Vomiting, Age 11 and Younger

Overview

Vomiting occurs when a child's stomach contents are forced up the esophagus and out of the mouth. Nausea is a sick feeling in the pit of the stomach. Although nausea may come with vomiting in adults and older children, children younger than age 3 usually can't tell you if they have it. Most of the time vomiting isn't serious. Home treatment will often ease your child's discomfort.

Vomiting in a baby should not be confused with spitting up. Vomiting is forceful and repeated. Spitting up may seem forceful. But it usually occurs shortly after feeding, is effortless, and causes no discomfort.

Causes of vomiting

A baby may spit up for no reason at all. Overfeeding, not burping your baby after feeding, intolerance to milk or formula, and exposure to tobacco smoke are other reasons why your baby may spit up.

Most vomiting in children is caused by a viral stomach illness (gastroenteritis). A child with a stomach illness also may have other symptoms, such as diarrhea, fever, and stomach cramps. With home treatment, the vomiting usually will stop within 12 hours. Diarrhea may last for a few days or more.

Rotavirus is a virus that can cause severe vomiting and diarrhea. The rotavirus vaccine helps protect against rotavirus disease.

Vomiting can also be caused by an infection in another part of the body. Examples are strep throat, pneumonia, and urinary tract infections. In rare cases, vomiting can be a symptom of a serious condition. These include a blockage of the digestive tract (pyloric stenosis), an infection (meningitis) of the fluid (cerebrospinal fluid) and tissues (meninges) that surround the brain and spinal cord, and Reye syndrome.

When a toddler vomits, it's important to make sure that he or she has not swallowed medicines, household liquids, or other poisons. Look around the house for empty containers and spills. There may be pills in your child's vomit. Or the vomit may have an odd appearance, colour, or odour.

A child who falls down and forcefully hits his or her head or belly may vomit because of an injury to those areas. Check your child's body for bruises and other injuries.

Symptoms to watch for

If your baby is under 3 months of age and is vomiting, call 811 or your doctor.

Babies aged 3 to 12 months also need special attention if they continue to vomit. They can quickly become dehydrated. It is important to replace lost fluids when your child is vomiting. Watch your child carefully, and pay close attention to the amount of fluid they're able to drink. Look for early symptoms of dehydration:

  • Peeing less often than usual:
    • 3 to 5 months - dry diaper for more than 4 hours.
    • 6 to 23 months - dry diaper for more than 8 hours.
    • 2 years and older - no urine for more than 10 hours.
  • Low activity level (e.g., you can't distract them with play).
  • Not as responsive (e.g., they want to sleep more than they're awake, or they wake up only with stimulation).
  • Will not smile.
  • Dry lips but moist mucous membranes (inner cheek).
  • Few tears with crying.
  • Pale skin (may be flushed if they have a fever).

Also, be sure to notice the colour of the vomit, and count the number of times your child vomits. If your child vomits so often that you can't get them to drink, or if your child vomits every time they take a drink, the risk of dehydration is greater.

The medical assessment of symptoms is based on the body parts you have.

  • If you are transgender or non-binary, choose the sex that matches the body parts (such as ovaries, testes, prostate, breasts, penis, or vagina) you now have in the area where you are having symptoms.
  • If your symptoms aren’t related to those organs, you can choose the gender you identify with.
  • If you have some organs of both sexes, you may need to go through this triage tool twice (once as "male" and once as "female"). This will make sure that the tool asks the right questions for you.

Many things can affect how your body responds to a symptom and what kind of care you may need. These include:

  • Your age. Babies and older adults tend to get sicker quicker.
  • Your overall health. If you have a condition such as diabetes, HIV, cancer, or heart disease, you may need to pay closer attention to certain symptoms and seek care sooner.
  • Medicines you take. Certain medicines, such as blood thinners (anticoagulants), medicines that suppress the immune system like steroids or chemotherapy, or natural health products can cause symptoms or make them worse.
  • Recent health events, such as surgery or injury. These kinds of events can cause symptoms afterwards or make them more serious.
  • Your health habits and lifestyle, such as eating and exercise habits, smoking, alcohol or drug use, sexual history, and travel.

Try Home Treatment

You have answered all the questions. Based on your answers, you may be able to take care of this problem at home.

  • Try home treatment to relieve the symptoms.
  • Call your doctor if symptoms get worse or you have any concerns (for example, if symptoms are not getting better as you would expect). You may need care sooner.

Repeated vomiting: The child vomits nearly every time he or she tries to drink something. This type of vomiting makes it impossible to keep down any fluids or solid food, which greatly increases the chance of becoming dehydrated. The child has an even greater chance of dehydration if he or she also has diarrhea.

Occasional vomiting: Some young children vomit every once in a while for no clear reason. This usually does not increase the risk of dehydration or other problems as long as the child can keep down fluids between vomiting. The more time that passes between episodes of vomiting, the less serious it probably is. But if the vomiting continues, it may be important to find the cause.

Colic is an extreme type of crying in a baby between 3 weeks and 3 months of age. All babies cry, but a colicky baby will cry for hours at a time, no matter what you do.

During a crying episode, a colicky baby may cry loudly and continuously and be hard to comfort. The baby may get red in the face, clench the fists, and arch his or her back or pull the legs up to the belly.

Certain health conditions and medicines weaken the immune system's ability to fight off infection and illness. Some examples in children are:

  • Diseases such as diabetes, cystic fibrosis, sickle cell disease, and congenital heart disease.
  • Steroid medicines, which are used to treat a variety of conditions.
  • Medicines taken after organ transplant.
  • Chemotherapy and radiation therapy for cancer.
  • Not having a spleen.

If you're not sure if a child's fever is high, moderate, or mild, think about these issues:

With a high fever:

  • The child feels very hot.
  • It is likely one of the highest fevers the child has ever had.

With a moderate fever:

  • The child feels warm or hot.
  • You are sure the child has a fever.

With a mild fever:

  • The child may feel a little warm.
  • You think the child might have a fever, but you're not sure.

Babies can quickly get dehydrated when they lose fluids because of problems like vomiting or fever.

Symptoms of dehydration can range from mild to severe. For example:

  • The baby may be fussy or cranky (mild dehydration), or the baby may be very sleepy and hard to wake up (severe dehydration).
  • The baby may have a little less urine than usual (mild dehydration), or the baby may not be urinating at all (severe dehydration).

You can get dehydrated when you lose a lot of fluids because of problems like vomiting or fever.

Symptoms of dehydration can range from mild to severe. For example:

  • You may feel tired and edgy (mild dehydration), or you may feel weak, not alert, and not able to think clearly (severe dehydration).
  • You may pass less urine than usual (mild dehydration), or you may not be passing urine at all (severe dehydration).

Severe dehydration means:

  • The baby may be very sleepy and hard to wake up.
  • The baby may have a very dry mouth and very dry eyes (no tears).
  • The baby may have no wet diapers in 12 or more hours.

Moderate dehydration means:

  • The baby may have no wet diapers in 6 hours.
  • The baby may have a dry mouth and dry eyes (fewer tears than usual).

Mild dehydration means:

  • The baby may pass a little less urine than usual.

Severe dehydration means:

  • The child's mouth and eyes may be extremely dry.
  • The child may pass little or no urine for 12 or more hours.
  • The child may not seem alert or able to think clearly.
  • The child may be too weak or dizzy to stand.
  • The child may pass out.

Moderate dehydration means:

  • The child may be a lot more thirsty than usual.
  • The child's mouth and eyes may be drier than usual.
  • The child may pass little or no urine for 8 or more hours.
  • The child may feel dizzy when he or she stands or sits up.

Mild dehydration means:

  • The child may be more thirsty than usual.
  • The child may pass less urine than usual.

It is easy for your diabetes to become out of control when you are sick. Because of an illness:

  • Your blood sugar may be too high or too low.
  • You may not be able take your diabetes medicine (if you are vomiting or having trouble keeping food or fluids down).
  • You may not know how to adjust the timing or dose of your diabetes medicine.
  • You may not be eating enough or drinking enough fluids.

An illness plan for people with diabetes usually covers things like:

  • How often to test blood sugar and what the target range is.
  • Whether and how to adjust the dose and timing of insulin or other diabetes medicines.
  • What to do if you have trouble keeping food or fluids down.
  • When to call your doctor.

The plan is designed to help keep your diabetes in control even though you are sick. When you have diabetes, even a minor illness can cause problems.

Symptoms of serious illness in a baby may include the following:

  • The baby is limp and floppy like a rag doll.
  • The baby doesn't respond at all to being held, touched, or talked to.
  • The baby is hard to wake up.

Symptoms of serious illness may include:

  • A severe headache.
  • A stiff neck.
  • Mental changes, such as feeling confused or much less alert.
  • Extreme fatigue (to the point where it's hard for you to function).
  • Shaking chills.

Temperature varies a little depending on how you measure it. For children up to 11 years old, here are the ranges for high, moderate, and mild according to how you took the temperature.

Oral (by mouth), ear, or rectal temperature

  • High: 40° C (104° F) and higher
  • Moderate: 38° C (100.4° F) to 39.9° C (103.9° F)
  • Mild: 37.9° C (100.3° F) and lower

A forehead (temporal) scanner is usually 0.3° C (0.5° F) to 0.6° C (1° F) lower than an oral temperature.

Armpit (axillary) temperature

  • High: 39.5° C (103° F) and higher
  • Moderate: 37.5° C (99.5° F) to 39.4° C (102.9° F)
  • Mild: 37.4° C (99.4° F) and lower

Note: For children under 5 years old, rectal temperatures are the most accurate.

A baby that is extremely sick:

  • May be limp and floppy like a rag doll.
  • May not respond at all to being held, touched, or talked to.
  • May be hard to wake up.

A baby that is sick (but not extremely sick):

  • May be sleepier than usual.
  • May not eat or drink as much as usual.

Many non-prescription and prescription medicines can cause nausea or vomiting. A few examples are:

  • Antibiotics.
  • Antidepressants.
  • Aspirin, ibuprofen (such as Advil or Motrin), and naproxen (such as Aleve).
  • Medicines used to treat cancer (chemotherapy).
  • Opioid pain medicines.
  • Vitamins and mineral supplements, such as iron.

Starting a new medicine or increasing the dose can cause nausea and vomiting. Nausea and vomiting also may mean that there is too much medicine in your body, even if you took it properly.

Self-Care

Caring for your baby who has nausea and vomiting

Here are some tips for caring for newborns and babies younger than 1 year of age who have nausea and vomiting.

  • Don't let your baby get dehydrated.

    Don't wait until you see signs of dehydration in your baby. These signs include having fewer or no wet diapers and a dry mouth and dry eyes (fewer tears than usual).

    • If you breastfeed your baby, nurse him or her more often. Offer each breast to your baby for 1 to 2 minutes every 10 minutes.
    • If you use a bottle to feed your baby, increase the number of feedings to make up for lost fluids. The amount of extra fluid your baby needs depends on your baby's age and size. For example, a newborn may need as little as 30 mL (1 fl oz) at each extra feeding. A 12-month-old baby may need as much as 90 mL (3 fl oz) at each extra feeding.
    • Ask your doctor if you need to use an oral rehydration solution (ORS) if your baby still isn't getting enough fluids from formula or the breast. The amount of ORS your baby needs depends on your baby's age and size. You can give the ORS in a dropper, a spoon, or a bottle.
    • If your baby has started eating cereal, you may replace lost fluids with cereal. You also may feed your baby strained bananas and mashed potatoes if he or she has had these foods before.

Caring for your child who has nausea and vomiting

Here are some tips for caring for a child age 1 to 11 years who has nausea and vomiting.

  • Don't let your child get dehydrated.
    • Make sure that your child is drinking often. Frequent, small amounts work best.
    • Allow your child to drink as much fluid as he or she wants.
    • Encourage your child to drink extra fluids or suck on flavoured ice pops, such as Popsicles.
    • Don't give your child fruit juice or soda pop. They contain too much sugar and not enough of the essential minerals (electrolytes) that are being lost. Diet soda pop lacks calories that your child needs.
    • Cereal mixed with milk or water may also be used to replace lost fluids.
    • If your child still isn't getting enough fluids, you can try an oral rehydration solution (ORS).
  • Bit by bit, start to offer your child regular foods after 6 hours with no vomiting.
    • Offer solid foods if your child was eating solids before. Offer crackers, toast, broths, mild soups, mashed potatoes, rice, and breads to your older child.
    • Avoid high-fibre foods, such as beans, and foods with a lot of sugar, such as candy and ice cream.

When to call for help during self-care

Call a doctor if any of the following occur during self-care at home:

  • New or worse dehydration.
  • Severe vomiting.
  • New or worse belly pain.
  • Vomit contains blood or yellow or green liquid (bile).
  • Symptoms occur more often or are more severe.
