Insights

Obesity is linked to abnormal gallbladder and gastric motility, starting in pre-adolescence and worsening in adulthood, but not in newborns. Functional ultrasonography can detect these early motility changes.

Area of Science:

  • Gastroenterology
  • Pediatrics
  • Metabolic Disorders

Background:

  • Obesity is linked to impaired gallbladder and gastric motility in adults.
  • The exact timing of when this dysfunction appears is not well understood.

Purpose of the Study:

  • To investigate the age-related appearance of gallbladder and gastric motility dysfunction in obesity.
  • To assess if obesity affects motility in newborns, pre-adolescents, and adults.

Main Methods:

  • Noninvasive functional ultrasonography was used to assess gallbladder and gastric motility.
  • Studies included 50 newborns, 18 pre-adolescents, and 99 adults, categorized as lean or obese.
  • Motility was evaluated in fasting and postprandial states following milk or a test meal.

Main Results:

  • Obese newborns showed no differences in motility compared to lean newborns.
  • Obese pre-adolescents exhibited larger fasting gallbladder volume and slower gastric emptying than lean counterparts.
  • Obese adults displayed the most significant dysfunction, with larger residual gallbladder volumes and slower gastric emptying.

Conclusions:

  • Abnormal gallbladder and gastric motility patterns in obesity emerge in pre-adolescents and worsen with age.
  • These motility abnormalities are absent in obese newborns.
  • Functional ultrasonography is effective in detecting early stages of altered cholecysto-gastric motility, likely due to fat accumulation and insulin resistance.

Gastric Motility01:16

Gastric Motility

Gastric motility is the coordinated contraction and relaxation of stomach muscles that convert ingested food into chyme, a semi-liquid substance ready for further digestion in the intestines. The process begins with the vagus nerve inducing the relaxation of the smooth muscles in the fundus and body of the stomach, allowing these regions to expand and accommodate up to approximately 1.5 liters of food and liquid.

Gastrointestinal Motility Disorders01:20

Gastrointestinal 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...
Pyloric Obstruction01:11

Pyloric Obstruction

Pyloric obstruction, also referred to as gastric outlet obstruction, is a condition characterized by narrowing or blockage at the pylorus—the muscular valve regulating the flow of stomach contents into the duodenum. When this passage becomes impaired, the stomach cannot effectively empty its contents into the small intestine. This disruption leads to a range of gastrointestinal symptoms, including early satiety, bloating, epigastric pain, postprandial nausea, persistent vomiting, and...
Gastric Emptying01:16

Gastric Emptying

Gastric emptying occurs when the stomach gradually releases chyme into the duodenum. When the stomach is distended, it triggers the release of gastrin, a hormone that promotes gastric acid secretion to aid in digestion. Additionally, stomach distension contributes to peristaltic waves that propel gastric contents toward the pyloric region. The gastroenteric reflex, on the other hand, primarily stimulates peristalsis in the intestines, facilitating the movement of contents further along the...
Cholecystitis01:20

Cholecystitis

Cholecystitis is inflammation of the gallbladder, most commonly caused by obstruction of the cystic duct. This blockage prevents bile from draining, leading to gallbladder distension, inflammation, and potentially serious complications. This condition may present acutely or chronically and can happen with or without gallstones.EtiologyAbout 95% of cholecystitis cases are calculous, caused by gallstones blocking the cystic duct, leading to bile accumulation and inflammation of the gallbladder...

Pharmacokinetics in Pediatric Patients: Overview and Drug Absorption

Understanding the physiological differences in the pediatric population is crucial for effective pharmacotherapy. Neonates, infants, and children exhibit significant variations in gastric pH, gastric emptying time, intestinal transit time, and biliary function. These variations profoundly affect oral drug absorption, necessitating a nuanced approach to pediatric dosing.Neonates present with a unique physiological profile, having a gastric pH greater than 4 and faster and more irregular gastric...
