Disordered small intestinal motility: a rational basis for toddlers' diarrhoea
Gut
|October 1, 1983
Summary
Toddler diarrhea, a common childhood condition, may stem from abnormal intestinal motility. Studies show children with toddler diarrhea fail to exhibit a typical motor response to dextrose, suggesting a key role in its cause.
Area of Science:
- Pediatric Gastroenterology
- Gastrointestinal Motility Research
- Childhood Diarrhea Pathogenesis
Background:
- Toddler diarrhea is the most frequent cause of chronic diarrhea in children without failure to thrive.
- The underlying mechanisms (pathogenesis) of toddler diarrhea are not well understood.
- Understanding intestinal motility is crucial for diagnosing and treating gastrointestinal disorders in children.
Purpose of the Study:
- To investigate upper small intestinal motility patterns in children with toddler diarrhea.
- To compare the motility responses of children with toddler diarrhea to those of healthy children and children with other gastrointestinal issues.
- To explore the role of the migrating motor complex in the pathogenesis of toddler diarrhea.
Main Methods:
- Studied three groups of children: healthy controls, children with other gastrointestinal pathologies, and children with toddler diarrhea.
- Assessed fasting motor patterns and the response of the migrating motor complex (MMC) to cholecystokinin and intraduodenal dextrose.
- Utilized duodenal intubation for motility studies.
Main Results:
- No significant differences were observed in the basic characteristics of the migrating motor complex (MMC) between the groups.
- The response of the MMC to an intraduodenal bolus of 5% dextrose differed significantly among the groups.
- Children with toddler diarrhea (8/8) showed a complete failure of the MMC to be disrupted by intraduodenal dextrose, unlike control groups.
Conclusions:
- The failure of the intestinal motor response to dextrose in children with toddler diarrhea is a significant finding.
- This abnormal motor response is suggested to play a major role in the pathogenesis of toddler diarrhea.
- Further research into intestinal dysmotility could lead to new diagnostic and therapeutic strategies for toddler diarrhea.

01:20Gastrointestinal Motility Disorders
Gastrointestinal or GI motility disorders are characterized by irregular gastrointestinal tract movements, disrupting food transit from the mouth to the anus. They are caused by damage or dysfunction in gut muscles or nerves. These disorders can cause symptoms such as severe constipation, diarrhea, abdominal pain, and swallowing difficulties. Disorders can affect any segment of the GI tract and range widely in severity, from common conditions like GERD to life-threatening conditions like...
01:20Drugs Affecting GI Tract Motility: Adsorbents as Antidiarrheal Agents
Diarrhea is characterized by the occurrence of frequent, watery bowel movements. Various factors can trigger diarrhea, including viral or bacterial infections, foodborne illnesses, side effects from certain medications, and underlying digestive disorders. If not adequately managed, diarrhea can lead to complications such as dehydration, electrolyte imbalances, and nutrient deficiencies. Severe diarrhea can lead to significant weight loss, malnutrition, and weakened immune function.

01:18Drugs Affecting GI Tract Motility: Antimicrobials as Antidiarrheal Agents
Acute diarrhea, a common gastrointestinal disturbance, is characterized by the rapid evacuation of fluid stools, leading to an excessive weight in fluid. This condition typically arises from disorders affecting intestinal water and electrolyte transport. It can be triggered by an increased osmotic load within the intestine, excessive secretion of electrolytes and water, mucosal exudation of protein and fluid, or altered intestinal motility. The primary risks of acute diarrhea are dehydration...
01:17Drugs for Treatment of Diarrhea-Predominant IBS
Diarrhea-predominant irritable bowel syndrome (IBS-D) is a subtype of IBS characterized primarily by frequent, loose, or watery stools, abdominal pain, and abdominal discomfort. Therapeutic approaches to managing IBS-D include dietary changes, stress management techniques, and pharmaceutical interventions.
Two specific drugs used in the treatment are alosetron (Lotronex) and eluxadoline (Viberzi). Alosetron, a 5-HT3 antagonist, works by slowing the movement of stools in the gut, reducing bowel...

01:17Irritable Bowel Syndrome I: Introduction
Irritable Bowel Syndrome (IBS) is characterized by functional disturbances in the gastrointestinal system, presenting a cluster of symptoms without evident structural or biochemical abnormalities. It primarily affects the large intestine and may cause abdominal pain, bloating, excessive gas, diarrhea, constipation, or both.
IBS is a chronic condition that can persist over a long period or recur frequently.
The pathogenesis of IBS involves a complex interplay of the following factors:

DefinitionIrritable bowel syndrome (IBS) is a functional gastrointestinal disorder characterized by recurrent combinations of abdominal pain, bloating, diarrhea, or constipation.Pathophysiology of irritable bowel syndromeIts pathophysiology is multifactorial, involving disturbances in motility, sensory processing, microbial balance, barrier integrity, and gut–brain communication. These mechanisms interact to produce symptoms that vary across IBS subtypes.Altered Motility PatternsDisordered...
