Assessment of Gastric Emptying in Non-obese Diabetic Mice Using a [13C]-octanoic Acid Breath Test
Published on: March 23, 2013
Summary
High osmolality foods, not just acid, can trigger esophageal pain in sensitive individuals. This study highlights solution osmolality as a key factor in acid-sensitive esophagus pain, impacting heartburn triggers.
Area of Science:
- Gastroenterology
- Esophageal Physiology
- Clinical Nutrition
Background:
- Heartburn is commonly linked to specific foods.
- Food-induced esophageal discomfort may stem from lower esophageal sphincter effects or direct irritation.
- The role of solution osmolality in esophageal pain is not fully understood.
Purpose of the Study:
- To investigate the impact of solution osmolality on esophageal pain production.
- To differentiate the pain response to osmolality in acid-sensitive versus non-acid-sensitive individuals.
Main Methods:
- Subjects were categorized into acid-positive and acid-negative groups via the Bernstein test.
- Pain perception was evaluated using hypertonic saline and sucrose solutions (630 mOsm/kg water).
Main Results:
- A significant majority of acid-positive subjects (54-82%) experienced pain when exposed to hypertonic solutions.
- Only one acid-negative subject reported pain (p < 0.01), indicating a clear difference between groups.
Conclusions:
- High osmolality solutions are a significant cause of esophageal pain in acid-sensitive individuals.
- Dietary factors with high osmolality may be responsible for pain in the acid-sensitive esophagus.
- Osmolality should be considered alongside acidity in understanding food-triggered esophageal symptoms.

02:40Osmosis and Osmotic Pressure of Solutions
A number of natural and synthetic materials exhibit selective permeation, meaning that only molecules or ions of a certain size, shape, polarity, charge, and so forth, are capable of passing through (permeating) the material. Biological cell membranes provide elegant examples of selective permeation in nature, while dialysis tubing used to remove metabolic wastes from blood is a more simplistic technological example. Regardless of how they may be fabricated, these materials are generally...
01:30Other Disorders of Digestive System
The gastrointestinal tract is susceptible to various disorders. If the lower esophageal sphincter is damaged, stomach acid can flow back into the esophagus, causing irritation and inflammation of the lining. This condition is called gastroesophageal reflux disease (known as heartburn) and may cause chest pain and difficulty swallowing. In the stomach, prolonged use of nonsteroidal anti-inflammatory drugs like aspirin, chronic alcohol consumption, bacterial infections such as Helicobacter...
01:25Regulation of Water Intake
Osmolality refers to the number of solute particles per kilogram of solvent in a solution. Plasma osmolality specifically indicates the total number of solute particles per kilogram of water in blood plasma. This value reflects the body's hydration status and is tightly regulated through mechanisms controlling water intake and output. While water consumption is a conscious decision, the body has intrinsic regulatory systems to maintain fluid balance. Dehydration, a state of water deficit...
01:29Gastroesophageal Reflux Disease I: Meaning and Pathophysiology
Gastroesophageal Reflux Disease (GERD) involves the recurrent backflow of the stomach or duodenal contents into the esophagus, leading to troublesome symptoms and potential esophageal mucosal damage. Although GERD is often referred to as a disease, it is more accurately described as a syndrome, as it encompasses a range of symptoms and complications rather than a singular pathological entity, impacting a large number of individuals as the most prevalent upper gastrointestinal problem. Roughly...
01:21Hyperosmolar Hyperglycemic State
Hyperosmolar Hyperglycemic State, or HHS, is a serious and life-threatening complication of type 2 diabetes mellitus. It is characterized by three main features: severe hyperglycemia, profound dehydration, and elevated serum osmolality, all occurring without significant ketoacidosis.HHS typically develops in older adults or individuals with limited access to fluids. This may result from illness, cognitive impairment, or medications such as diuretics or corticosteroids. These factors reduce...
01:11Pyloric 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...
