Editing Constipation (section)

=== Fiber supplements ===
Soluble fiber supplements such as [[psyllium]] are generally considered first-line treatment for chronic constipation, compared to insoluble fibers such as wheat bran. Side effects of fiber supplements include bloating, flatulence, diarrhea, and possible [[malabsorption]] of iron, calcium, and some medications. However, patients with opiate-induced constipation will likely not benefit from fiber supplements.<ref name=AmericanGATReview>{{Cite journal|last1=Bharucha|first1=Adil E.|last2=Pemberton|first2=John H.|last3=Locke|first3=G.
