Stomach pain is very common in children. Most of the time the cause is harmless, such as constipation, gas, or a stress reaction. The most important thing is to watch the child as a whole: how they look, whether they drink, eat, play, and pass urine normally.
Home care is based on calming the child, using warmth on the belly, and making sure fluids are taken in. Most stomach aches settle on their own. Seek care if the pain is strong and constant, if the child will not drink, or if the abdomen becomes hard and swollen.
The overall condition matters more than one symptom#
With a child’s stomach ache, the whole child matters more than a single symptom. Can they play, do they drink, do they pass urine, is their skin warm, and do they seem otherwise like themselves. Mild pain with normal behaviour in between is a different situation from pain that makes the child limp or withdraw.
The location and duration of the pain help, but they do not decide everything on their own. Pain in the lower right abdomen, a hard and swollen abdomen, repeated vomiting, blood in stool, or a clearly declining general condition all make assessment more sensible.
Common causes#
Constipation is the most common cause of stomach pain in children. Hard, infrequent stools can cause cramp-like pain that comes and goes. The pain is often around the navel or in the lower abdomen. Changes in diet, drinking too little, and holding back the urge to use the toilet all increase the risk.
A stomach bug causes sudden abdominal pain with vomiting or diarrhoea. It usually passes within a few days. The main issue is fluid intake. Small amounts often are better than large amounts at once.
Functional abdominal pain means repeated stomach pain without a clear physical cause. It is common in school-aged children and often links to stress, tension, or an oversensitive gut. The pain is real even when tests do not show a single clear explanation.
Food-related issues, such as lactose intolerance or coeliac disease, can also cause repeated pain. If the pain clearly follows certain foods, it is worth checking further.
Home care#
Calm reassurance and closeness often help. A warm wrap on the belly can ease cramping. Rest and light food are usually enough. Some children feel better lying on their side with knees bent, while others prefer lying on their stomach.
Hydration matters especially during a stomach bug. Small amounts often are better than large amounts. Water, diluted juice, and broth are simple options.
For constipation, fibre, enough drinking, and a regular toilet routine are important. If diet changes are not enough, a laxative may be needed, but that should be chosen according to age and situation.
For functional pain, a normal daily rhythm and being listened to help more than chasing the pain. Too much focus on the symptom can keep it going.
Common mistakes#
Child stomach pain is sometimes dismissed, especially when no clear cause is found. Functional abdominal pain is still real pain, and the child needs to feel heard. On the other hand, too much worry and repeated questioning can make the child focus on the pain more. A calm response and keeping daily life as normal as possible often help most.
Is it stomach pain or something else#
In younger children, stomach pain can also be a sign of a throat or ear infection, because a small child may not localise pain well. If fever is present, check whether there are throat or ear symptoms too. A urinary tract infection can also show up as stomach pain, especially in young girls.
When to seek care#
Seek care if the pain is strong and constant, if the child will not drink or keep fluids down, if the abdomen is hard and swollen, if vomiting and fever happen together, if the child wakes from sleep because of the pain repeatedly, or if the general condition worsens clearly. Pain in the lower right abdomen can point to appendicitis and needs urgent assessment.
