The Role of Diet in the Management of Non-ulcer Dyspepsia

Abstract

BACKGROUND

Dyspepsia is a common symptom with an extensive differential diagnosis and a heterogeneous pathophysiology. Many studies have reported that dyspeptic symptoms are associated with ingestion of some foods. Current treatments for functional dyspepsia have generally ignored the potential role of diet.

METHOD

This cross-sectional study was done at the Gastroenterology Department of Shahid Sadoughi Hospital, Yazd, Iran from September 2008 to March 2009. Based on the diagnostic criteria for functional dyspepsia symptoms presented to outpatient gastroenterology clinics, adult patients were invited to participate in this study. Upper GI endoscopy was performed in all the patients so as to rule out any gross pathology. The patients were asked about a list of nutrients including 114 foods which is commonly used in our area. Then, the effects of specific foods were identified on the relief or aggravation of the symptoms with four degrees: low, medium, high, and very high.

RESULTS

Of 384 patients, 152 were men and 231 were women with a mean ± SD age of 39.16±14 years (range: 13-80 years). The foods that caused the highest aggravation of symptoms were sausage and bolognas, pickles vinegar, soft drinks, grain, tea, salt, pizza, watermelon, red pepper, and macaroni. However, the most frequent foods that led to the alleviation of symptoms were apples, rice, rock candy, bread, caraway seed, dates, honey, yogurt, quince, and walnut.

CONCLUSION

This study shows that some foods, especially spicy, pickled, and high-fat foods, strongly induced dyspepsia and aggravated the symptoms in dyspeptic patients.
