Stomach pain in children

It is very common for children to have stomach ache. Children may have a stomach ache for many different reasons, but usually it is not dangerous. Often, stomach pain goes away by itself, but sometimes the child may need treatment.

This text is about children who have stomach ache. For adolescent adolescents, stomach pain can sometimes have causes that are more common in adults.

Children cannot always say where it hurts

It can be difficult for a toddler to feel and describe exactly where in the stomach the pain comes from.

Children up to about three years of age often point to the stomach if you ask where they are in pain, even if the pain comes from some other part of the body. Older children may also have difficulty saying where it hurts. Up to six to seven years of age, children almost always point to the belly of the navel when you ask where it hurts. With increasing age, the child can better describe the pain and can indicate if it hurts more on the right or left side, or if the pain is high or low.

When and where should I seek care?

Most children who get stomach upset without other symptoms do not need to seek care. The trouble usually goes by itself.

If a child has had a problem for a long time or if the problems come back, contact a health care center or pediatrician.

If it is a weekend, you can wait until it is everyday. You can contact many receptions by logging in.

If it’s in a hurry

If the child has one or more of the following problems, immediately contact a health care center or on-call clinic:

  • The child has both stomach pain and other symptoms, such as fever, swelling of the groin, sore throat, black and loose poop or poop containing fresh blood, more than just occasional streaks.
  • The baby has a stomach ache that is clearly swollen, and neither poop nor gases come out.
  • The child is tired and brought on by the pain.
  • Pain that does not pass, becomes more severe, is very intense or seems to move towards one side.
  • The child is in pain at clear intervals.
  • The baby is very sore on one side of the stomach.
  • The child has abdominal pain and burning when they are kissing.

If it is closed at the health center or on-call reception, seek care at an emergency room.

Call telephone number 911 for medical advice. Then you can get help to assess symptoms or help with where you can seek care.

Investigations and investigations

The child may need to be assessed and examined by a physician to find out why they are in pain and how the problems can best be treated.

It is not always easy for the doctor to determine the cause of the pain. It is therefore important to describe the symptoms as carefully as possible. Usually, it is precisely the description of the trouble that gives the most important clues.

Prepare the child or yourself using the following questions:

  • How did the trouble start and has it gotten better or worse since then?
  • Exactly where does it hurt? Always in the same place?
  • How long has it been going on?
  • Exactly where does it hurt? Always in the same place?
  • Are there other symptoms at the same time?
  • When does it hurt? Is it most in the evening, in the middle of the night, at school, on weekends?
  • Does it hurt all the time or does the pain come at intervals?
  • What improves and worsens the hassles? Food? Going to the toilet? To lie still or to think of something else?
  • Does anyone in the family have or have had similar symptoms?
  • Any treatments that have been tried and worked or not worked?

It is important to include information on how the child has grown and developed for the visit to the doctor. Therefore, bring your health card from the child care center or from the school health care if your child is of school age.

The doctor examines the stomach and takes samples

The doctor also examines the child by, among other things, feeling the stomach. Often, the child may pass urine, stool and blood tests. Sometimes the child may also need to be examined with ultrasound or x-ray. The child may sometimes need to stay in hospital so that doctors can monitor how the child is feeling and can safely exclude certain reasons why it hurts.

Children should be able to participate

There is no age limit for when a child can have influence over their care. The child’s ability to participate is related to the child’s maturity.

The older the child, the more important it is for them to be involved in their care. In order to be active in the care and to make decisions, it is important that you as an adult and the child understand the information you receive from the healthcare staff.

You have the opportunity to interpret other languages ​​if one of you does not speak Swedish. You also have the option of interpreting assistance if, for example, one of you has a hearing impairment.

The baby often aches with soreness around the navel, and sometimes the soreness can move to the right lower part of the abdomen where the appendix is ​​located. The child often gets a little higher body temperature, up to 38-38.5 degrees.

Similar disorders occur in the so-called glandular or glandular abdomen.

Functional gastrointestinal disorders

The most common cause of prolonged and recurrent stomach pain is called functional gastrointestinal disorders. Another term for some of these disorders is irritable bowel disease, IBS.

The problems can vary, but usually they last for longer than two months and come at least once a week. Other symptoms may include acid reflux, vomiting, constipation or diarrhea. Sometimes, the trouble can increase during periods of stress.

Colds and other viral infections

In preschool children, it is not uncommon for a cold to cause stomach pain. This is probably due to the fact that the infection settles in parts of the intestinal mucosa and causes the intestines to move worse than usual and that more gases are formed.

Gastroesophageal reflux disease

It is common for infants to vomit. But when a child with copious, prolonged vomiting gets stomach upset or does not gain weight, it can be called gastroesophageal reflux disease.

The child usually gets abdominal pain suddenly, becomes pale and quiet, and sometimes gets screaming attacks. The pain comes and goes in intervals. The time between the pain attacks is getting shorter until the child is in pain all the time. Intestinal blockage causes the child to feel ill and vomit, and that neither poop nor gas can come out.

It is unusual, but the risk of invagination may increase some of the rotavirus vaccine.

Glandular Stomach

Glandular or glandular is thought to be due to the fact that swollen lymph nodes in the stomach cause the bowel to move worse than usual. It causes pain when the gut does not pass through the intestine. Often, the gland is due to a viral infection, which at the same time can cause more or less high fever. Sometimes the problems of the gland after an infection can be quite prolonged.

The gland can be mistaken for appendicitis.

Lactose intolerance

Many children of extra-Nordic origin develop lactose intolerance from early childhood and upwards. That means the gut bacteria ferment milk sugar, lactose, in the diet. It gives rise to gases and diarrhea, which can lead to stomach pain.


Groin hernia in children is usually congenital and is then seen as a rounded bulge at the groin or in the scrotum. Groin hernia is due to a part of the peritoneum and intestine being pushed through the abdominal wall so that a sac is formed under the skin.

Urinary infection

In the case of urinary tract infection, it often fades when the baby is peeing. The baby kisses more often than usual, can pee and often get a stomach ache. There may be some blood in the kiss, which may smell bad.
