Abstract

Background/Aims

Postprandial symptoms of fullness and abdominal discomfort are common after fatty meals. Gastric lipases hydrolyze 10% to 20% of dietary triglycerides during the stomach trituration period of digestion. The aim of this study was to evaluate the effects of acid-resistant lipase on upper gastrointestinal symptoms, including fullness and bloating, as well as on gastric myoelectrical activity after healthy subjects ingested a high-fat, liquid meal.

Methods

This study utilized a double-blind, placebo-controlled, crossover design with 16 healthy volunteers who ingested either a capsule containing 280 mg of acid-resistant lipase or a placebo immediately before a fatty meal (355 calories, 55% fat). Participants rated their stomach fullness, bloating, and nausea before and at timed intervals for 60 minutes after the meal. Electrogastrograms were obtained to assess the gastric myoelectrical activity.

Results

Stomach fullness, bloating, and nausea increased significantly 10 minutes after ingestion of the fatty meal (p<0.01), whereas normal gastric myoelectrical activity decreased and tachygastria increased (p<0.05). With lipase, reports of stomach fullness were significantly lower compared with placebo (p<0.05), but no effect on gastric myoelectrical activity or other upper gastrointestinal symptoms was observed.

Conclusions

The high-fat meal induced transient fullness, bloating, nausea, and tachygastria in healthy individuals, consistent with post-prandial distress syndrome. Acid-resistant lipase supplementation significantly decreased stomach fullness.

Functional gastroduodenal disorders.

R Heading, V Stanghellini, Lisa Koch … (1999)

While widely used in research, the 1991 Rome criteria for the gastroduodenal disorders, especially symptom subgroups in dyspepsia, remain contentious. After a comprehensive literature search, a consensus-based approach was applied, supplemented by input from international experts who reviewed the report. Three functional gastroduodenal disorders are defined. Functional dyspepsia is persistent or recurrent pain or discomfort centered in the upper abdomen; evidence of organic disease likely to explain the symptoms is absent, including at upper endoscopy. Discomfort refers to a subjective, negative feeling that may be characterized by or associated with a number of non-painful symptoms including upper abdominal fullness, early satiety, bloating, or nausea. A dyspepsia subgroup classification is proposed for research purposes, based on the predominant (most bothersome) symptom: (a) ulcer-like dyspepsia when pain (from mild to severe) is the predominant symptom, and (b) dysmotility-like dyspepsia when discomfort (not pain) is the predominant symptom. This classification is supported by recent evidence suggesting that predominant symptoms, but not symptom clusters, identify subgroups with distinct underlying pathophysiological disturbances and responses to treatment. Aerophagia is an unusual complaint characterized by air swallowing that is objectively observed and troublesome repetitive belching. Functional vomiting refers to frequent episodes of recurrent vomiting that is not self-induced nor medication induced, and occurs in the absence of eating disorders, major psychiatric diseases, abnormalities in the gut or central nervous system, or metabolic diseases that can explain the symptom. The current classification requires careful validation but the criteria should be of value in future research.

Dyspepsia and dyspepsia subgroups: a population-based study.

N J Talley, A R Zinsmeister, C D Schleck … (1992)

It has been proposed that patients with dyspepsia can be classified into symptom groupings that may represent different pathophysiological entities; however, it remains to be shown that distinct symptom subgroups exist. To estimate the prevalence of dyspepsia (defined as upper abdominal pain) and dyspepsia subgroups, an age- and sex-stratified random sample of Olmsted County, Minnesota, residents, aged 30-64 years, were mailed a valid self-report questionnaire; 82% responded (n = 835). Subgroups were as follows: those with symptoms suggestive of peptic ulceration (ulcerlike dyspepsia), those with gastric stasis (dysmotilitylike dyspepsia), those with gastroesophageal reflux (refluxlike dyspepsia), and the remainder (unspecified dyspepsia). Ulcerlike dyspepsia was the commonest subgroup (prevalence, 16.0/100; 95% confidence interval, 13.4-18.5), but 43% of subjects with dyspepsia could be classified into more than one subgroup. Nearly one third of dyspeptics also had irritable bowel symptoms, but these were not confined to any particular dyspepsia subgroup. Although dyspepsia is very common in the community and the majority have ulcerlike symptoms, there is such overlap among the dyspepsia subgroups that a classification based on symptoms alone in uninvestigated patients may not be useful.

Role of impaired gastric accommodation to a meal in functional dyspepsia.

B Coulie, Geert Janssens, H Piessevaux … (1998)

Impaired accommodation of the proximal stomach to a meal has been reported in functional dyspepsia, but its relevance to symptoms is unclear. The aim of this study was to test the hypothesis that impaired gastric accommodation causes early satiety. A gastric barostat was used to study postprandial fundus relaxation in 35 healthy subjects and 40 patients with functional dyspepsia. Gastric emptying, Helicobacter pylori status, sensitivity to gastric distention, and a dyspepsia symptom score were obtained from all patients. In addition, the effect of sumatriptan, a fundus-relaxing 5-hydroxytryptamine1 agonist, on gastric accommodation and on early satiety in dyspeptic patients was studied. Impaired gastric accommodation to a meal was found in 40% of the patients. In univariate analysis, this was associated with early satiety and weight loss but not with hypersensitivity to gastric distention, presence of H. pylori, or delayed gastric emptying. In a multivariate analysis, only early satiety was associated with impaired gastric accommodation. Sumatriptan restored gastric accommodation, thereby significantly improving meal-induced satiety. Impaired relaxation of the proximal stomach to a meal is present in a high proportion of patients with functional dyspepsia. It is associated with symptoms of early satiety. Restoring gastric accommodation with a fundus-relaxing drug improves early satiety.
