Dietary fat intake can worsen dyspeptic symptoms, particularly fullness and nausea. Reducing fatty food consumption may be beneficial for managing functional dyspepsia (FD), but further research is needed.
Area of Science:
- Gastroenterology
- Human Nutrition
Background:
- Functional dyspepsia (FD) is a common gastrointestinal disorder.
- The role of dietary fat in triggering dyspeptic symptoms is not fully understood.
Purpose of the Study:
- To review existing literature on the relationship between dietary fat intake and functional dyspepsia.
Main Methods:
- A systematic literature search was conducted on PubMed.
- Keywords included FD, dietary fat, dyspeptic symptom, energy intake, and nutrients.
- 19 relevant English papers published between 1992 and 2012 were analyzed.
Main Results:
- Fatty foods are anecdotally linked to dyspepsia.
- Laboratory studies show fat intake increases fullness, bloating, and nausea in FD patients.
- Lipids, especially long-chain triglycerides, exacerbate gastric distension hypersensitivity more than glucose.
Conclusions:
- Dietary fat intake appears to exacerbate dyspeptic symptoms in individuals with FD.
- Reducing fatty food consumption may offer symptomatic relief.
- Further clinical evaluations are recommended to confirm the efficacy of dietary fat reduction.
