A change in fiber intake or sensitivity to an ingredient can affect digestion. Two of the US shakes described here and one bar provide 28 g fiber before your regular meal, so changing your intake suddenly may feel uncomfortable.
Introduce higher-fiber foods gradually and drink fluids regularly unless your clinician has advised a fluid restriction. If symptoms are persistent, worsening or more than mild, stop the product and seek medical advice. Do not keep using it for a fixed number of days hoping symptoms will pass. Contact us to report the issue.
