If your child frequently experiences stomach pain, nausea or diarrhea before school, it may be more than ordinary morning jitters. In some cases, a cluster of stress-related gastrointestinal (GI) symptoms, known as DGBIs, disorders of gut-brain interaction may be the problem.
“These symptoms may involve changes in how the gut and brain communicate. Although they cause significant physical discomfort, routine medical testing may not reveal an underlying problem,” explains
Lesley Small-Harary, MD, a pediatric gastroenterologist at Stony Brook Children's Hospital. “Stress can play a role, particularly when school or other aspects of a child's life become overwhelming.”
Common symptoms of DGBIs include abdominal pain, diarrhea and nausea. Separately, stress can also cause headaches, dizziness, lightheadedness or heart palpitations in some children.
“While the exact etiology of DGBIs is not fully understood, we know there is a significant overlap in physical symptoms that manifest in children when they're very stressed,” says Dr. Small-Harary. “For various reasons, school is a common stressor for kids.” Stress-related symptoms can begin in early childhood but are most commonly found in teenagers.
Clues that Stress May Be Playing a Role
Because stress-related GI symptoms are real and can be just as distressing as those caused by other medical conditions, it isn't always easy for parents to know what's behind them. The following patterns may offer clues that stress is contributing.
Symptoms appear in the morning
Symptoms can occur at any time but those related to school stress tend to pop up at the start of the day. "A lot of kids feel the need to go to the bathroom and can have diarrhea and/or stool urgency from stress when they wake up” says Dr. Small-Harary.
Symptoms improve as the day progresses
Whether a child stays home or pushes through and goes to school, symptoms gradually improve.
Symptoms follow the school calendar
If you’re dealing with a DGBI, symptoms may be less severe and improve over weekends, evenings, school breaks and during the summer.
Medical Warning Signs Not to Ignore
Blood in the stool, waking overnight to have a bowel movement, unexplained weight loss, fever or significant abdominal bloating warrant further evaluation. “Bring these symptoms to your pediatrician's attention promptly,” says Dr. Small-Harary.
“When the red flag symptoms [listed above] are absent, testing often doesn't identify a cause, suggesting a possible DGBI," she explains.
When to Seek Medical Advice
If your child experiences recurring abdominal pain, nausea, diarrhea or other GI symptoms, Dr. Small-Harary suggests consulting your pediatrician. “Your child's doctor can help determine whether further testing is needed and refer you to a pediatric gastroenterologist when appropriate."
