Hylocereus Polyrhizus

Introduction: The red dragon fruit (Hylocereus polyrhizus) is a popular fruit, not only where it originated from, in Central America, but across the world including in Asia. It contains healthy minerals, vitamins and antioxidants, and has been shown to have gut motility action in animals. Methods: To determine the effect of red dragon fruit on whole gut transit time, a cross-sectional study of whole gut transit time using two different stool markers was conducted among 128 young Malaysian adults. Results: Red dragon fruit, in a half fruit serving of 225±25 grams, reduced mean whole gut transit time from 26.0±12.9 hours to 21.9±12.8 hours (p<0.001) when colour change in stools was used as an indicator. The tests also showed that 14.8-17.3% of individuals had whole gut transit time ≥40 hours with carbon as a stool marker compared to only 7.8-8.6% when red dragon fruit was consumed and used as a marker. Conclusion: This study demonstrated a laxative effect of red dragon fruit among young adults.

Colon Transit

Introduction: Functional constipation is one of the most common gastrointestinal symptoms which could affect patients’ quality of life. The colonic transit time test could be used for determining functional constipation subtypes. The aim of our study was to determine the abnormalities of the subtypes of functional constipation using CTT. Methods and Materials: This cross-sectional study was performed on 85 patients in 2011 in Shariaaty Hospital, Isfahan. All the patients received 60 radio-opaque markers, and they underwent radiological evaluation 5 days afterwards. Functional constipation was determined according to the distribution of the markers in the colon. Result: The samples consisted of 24 males and 61 females at a mean age of 42.7 ± 16.28 years. The colonic transit time results showed that 71 patients had normal transit time, 6 had a composite type, 5 had slow transit, and 3 had pelvic delay. There was no significant difference between sex and colon transit time types (P value =0.32). The mean colon transit time in our study was 51.8 ± 16.3 hours. Conclusion: Functional constipation patients should undergo CTT, especially those who use maneuvers for defecation and those who need more time for defecation.[GMJ. 2012;1(2):48-52]
