Insights
Fructose malabsorption is common in children with functional bowel disorders. Dietary changes effectively reduce gastrointestinal symptoms in these patients.
Area of Science:
- Pediatric Gastroenterology
- Digestive Health
- Clinical Nutrition
Background:
- Functional bowel disorders are a common cause of abdominal pain in children.
- Fructose malabsorption is increasingly recognized as a potential contributor to these symptoms.
Purpose of the Study:
- To determine the prevalence of fructose malabsorption in pediatric patients with functional abdominal pain.
- To assess the impact of fructose intake restriction on symptom reporting and severity.
- To investigate the relationship between fructose dosage and symptom manifestation.
Main Methods:
- A fructose breath test was administered to children with unexplained abdominal pain.
- Participants received varying doses of fructose (1g, 15g, 45g) with breath hydrogen measured.
- Positive test results were defined by elevated breath hydrogen and accompanying gastrointestinal symptoms.
Main Results:
- None of the patients receiving 1g of fructose had positive results.
- Positive fructose malabsorption tests occurred in 30% (15g dose) and 61.5% (45g dose).
- Dietary restriction of fructose led to rapid and sustained improvement in gastrointestinal symptoms for most affected children.
Conclusions:
- Fructose malabsorption is a significant factor in pediatric functional abdominal pain.
- Managing dietary fructose intake is an effective strategy for alleviating gastrointestinal symptoms in children.
Objectives:
We determined the occurrence of fructose malabsorption in pediatric patients with previous diagnoses of abdominal pain caused by a functional bowel disorder, whether the restriction of fructose intake changes the reporting of symptoms, the role of fructose dosage, and the severity of resultant symptoms.
Patients And Methods:
We administered a fructose breath test to children presenting with persistent unexplained abdominal pain. Patients randomly received 1, 15, or 45 g fructose, and breath hydrogen was measured for 3 hours after ingestion. Test results were positive when breath hydrogen was 20 ppm greater than baseline and was accompanied by gastrointestinal symptoms.
Results:
A total of 32 patients was enrolled, and none of the 9 who received 1 g had positive results. Three of 10 who received 15 g and 8 of 13 who received 45 g had positive results. All patients with positive test results restricted their fructose intake. Among the group with positive results, 9 of 11 had rapid improvement of their gastrointestinal symptoms. After 2 months, all 9 patients continued to report improvement.
Conclusions:
We concluded that fructose malabsorption may be a significant problem in children and that management of dietary intake can be effective in reducing gastrointestinal symptoms.

Glucose Transporters
Facilitated diffusion-glucose transporters (GLUTs) are encoded by the solute-linked carrier (SLC) family 2, subfamily A gene family, or SLC2A. The 14 GLUT protein members are distributed into three classes:

Chronic Pancreatitis I: Introduction
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...
