Effect of Zinc Supplementation on the Frequency and Consistency of Stool in Children with Acute Diarrhea

Introduction Acute diarrhea in young children is a prevalent and distressing pediatric illness. The role of zinc therapy in the improvement of stool consistency and the shortening of the duration of diarrhea is still controversial. The aim of this study is to assess the effect of oral zinc supplementation in acute diarrhea. Methods Children of age 28 days till five years presenting in the outpatient department with acute diarrhea were included. Oral zinc supplementation was included in the anti-diarrheal regime of half of the children (n=50); the other half (n=50) were not given zinc. Mean body weight and the frequency and consistency of stool were noted for both groups on Days 1 and 3. Results The zinc group showed a significantly reduced frequency of diarrheal episodes on the third day of intervention (p<.00001). More children in the zinc group had soft to firm stool consistency than in the non-zinc group (p=.01). Conclusion Oral zinc supplementation has a promising role in reducing the duration of diarrhea and improving stool consistency in children with acute diarrhea. Oral zinc supplementation should be made a mandatory part of the anti-diarrheal regime for Pakistani children.
