Teenagers’ stomach pain often signals a wider burden of pain, stress and school struggles

A nationally representative Hungarian study found that persistent abdominal pain in teenagers commonly overlaps with pain elsewhere in the body, poorer wellbeing, bullying and difficulties at school.

Parents who are relieved to learn that a child’s recurring stomach ache has no obvious physical cause may still want to look more closely at the wider picture, according to new research from Semmelweis University. The study suggests that persistent abdominal pain in adolescents is often not an isolated complaint but part of a broader pattern of pain, stress and reduced wellbeing that can affect school life and daily functioning.

The findings, published in the International Journal of Pediatrics, were based on a nationally representative survey of 522 Hungarian schoolchildren aged 11 to 18. Researchers found that among teenagers diagnosed with functional abdominal pain disorder – recurring or ongoing belly pain without an organic explanation – symptoms frequently overlapped with pain elsewhere in the body. More than four in five of those affected reported pain in at least two body areas, and more than half said the abdomen was not even the main source of discomfort. Headaches, joint pain and back pain were the most common additional complaints, and in many cases the pain had lasted for at least a year.

That pattern fits with earlier paediatric research showing that multisite pain is common in children with functional abdominal pain disorders and is linked with greater illness burden. A study published in The Journal of Pediatrics found that most children in its sample had pain outside the abdomen as well, along with more frequent and severe abdominal symptoms and higher levels of anxiety and depression. Other work has suggested that some children with these disorders may also have increased visceral sensitivity, meaning the gut feels pain more easily, while psychological factors can shape how symptoms develop and persist.

Semmelweis researchers said the pain may begin after an infection or inflammation, but if it continues and is joined by stress, anxiety or other psychological strain, the body’s pain system can become sensitised. In that state, even small triggers can set off pain, and ordinary processes such as digestion after a meal may start to feel painful. That helps explain why symptoms can spread beyond the abdomen and become entrenched over time. Similar concerns appeared in a five-year follow-up study published in the Journal of Pediatric Gastroenterology and Nutrition, which identified a subgroup of children whose symptoms and impairment stayed high, particularly when anxiety, depression and difficult life events were present.

The Semmelweis study also linked functional abdominal pain with problems in school and social life. Children who reported this condition were more likely to say their classrooms felt too demanding, too noisy or unfairly managed, and they were more likely to experience exclusion or bullying by classmates. The research also found poorer quality-of-life scores across emotional, social and educational measures. Nearly 15% of those with functional abdominal pain fell into a particularly severe category, and verbal bullying such as mockery or insults was associated with that group. In practical terms, affected pupils missed more school, used painkillers more often and struggled more with concentration, participation and keeping up with lessons.

Doctors and researchers have long warned that these symptoms should not be dismissed simply because no structural disease is found. Earlier studies have shown that children with chronic non-organic abdominal pain often withdraw socially, miss school and face lasting disruption to daily life, while follow-up research has linked childhood somatic complaints with later gastrointestinal problems. The latest findings from Semmelweis underline the value of early attention, since timely support – sometimes including a change in environment or a short course of psychotherapy – may reduce the risk that pain becomes a long-term problem continuing into adulthood.
