Brief Summary

Functional constipation is a widely prevalent pediatric issue, with a prevalence in some studies as high as 32.2%. Treatment consists of a combination of behavioral and pharmacological interventions (mainly, administration of polyethylene glycol laxatives or the use of enemas). Glucomannan (GNN) is a polysaccharide of 1,4-D-glucose and D-mannose found in the soluble fiber of some plants. While studies available in the literature to date agree that mannite is a dietary supplement with safe use, the usefulness of this compound remains controversial.

Administration of supplement dietary manna

Dietary Supplement: Manna

Interventions

MannaDIETARY_SUPPLEMENT

Administration is by the oral route according to weight at a dosage of 1 g/kg/day, dissolved in a glass of water, up to a maximum of 30 g. Administration should be repeated every 24 h for 8 weeks, accompanied by plenty of hydration. In case an effective dosage is achieved (evacuation within 72 h) it will be maintained until the end of the study. If evacuation has not occurred after 72 h, evacuative enema and increased dosage to 1.5 g/kg/day will be indicated. If further evacuative enema is needed, product administration will be discontinued and classical polyethylene glycol therapy will be started as per guidelines.
