“…Physiologically, visceral fullness sensations derive from mechanoreceptors located in the stomach that are linked to the brain via the vagus and splanchnic nerves (Janssen et al, 2011;Klatt et al, 1997;Lee, Vos, Janssens, & Tack, 2004). Following the cessation of eating, sensations of fullness may be governed by the rate of gastric emptying, which is inversely proportional to the energy content of the ingested food (e.g., Calbet & MacLean, 1997).…”

“…In a well-controlled study, Klatt et al 34 investigated whether severe obesity is related to gastric dysfunction or to abnormal perception in response to distension: 31 obese patients and 20 healthy volunteers were studied using an electronic barostat. Basal gastric tone, gastric accommodation, and perception in response to distension were not altered in obese patients.…”

The onset of obesity occurs as a result of an imbalance between nutrient consumption/absorption and energy expenditure. Gastrointestinal (GI) motility plays a critical role in the rate of consumption of foods, digestion, and absorption of nutrients. Various segments of the GI tract coordinate in a complex yet precise way, to control the process of food consumption, digestion, and absorption of nutrients. GI motility not only regulates the rates at which nutrients are processed and absorbed in the gut, but also, via mechanical and neurohormonal methods, participates in the control of appetite and satiety. Altered GI motility has frequently been observed in obese patients, the significance of which is incompletely understood. However, these alterations can be considered as potential contributing factors in the development and maintenance of obesity and changed eating behavior. Therapies aimed at regulating or counteracting the observed changes in GI motility are being actively explored and applied clinically in the management of obese patients.

“…Impaired gastric accommodation is associated with upper gastrointestinal symptoms such as early satiety (30) . Several studies did not find differences in the gastric accommodation of obese subjects compared to controls (18,19,30) , a fact that should change after v. , e 48 sujeitos que haviam sido submetidos a cirurgia bariátrica para tratamento de obesidade classe III. Utilizou-se na avaliação o teste de deglutição de água.…”

-Context -Bariatric surgery is an effective treatment for obesity; however, after surgery the patient may have difficulty in swallowing liquid and solid foods. Objectives -To evaluate liquid ingestion in patients who had undergone bariatric surgery. Method -We studied 43 volunteers with normal body mass index (BMI) (BMI: 18.5-24.9 kg/m 2 ), 55 subjects with class III obesity (BMI: >40.0 kg/m 2 ), and 48 subjects with bariatric surgery for treatment of class III obesity. The method chosen for evaluation was the water swallowing test. The subjects drank in triplicate 50 mL of water while being precisely timed and the number of swallows were counted. Results -There was no difference between subjects with normal BMI and subjects with class III obesity. During the first 2 months after bariatric surgery the patients showed an increase in the time needed to drink the entire volume, in the number of swallows, and in the inter-swallow interval, and a decrease in the volume swallowing capacity (volume/swallowing) and swallowing flow rate (volume swallowed/second). After 2 months, the results of the swallowing measurements moved in the direction of normal values. Conclusion -Bariatric surgery may cause more intense alterations of liquid bolus swallowing within 2 months after the procedure, which moved to normal values after this time. HEADINGS -Drinking.
