Current individualized regimens rely largely on higher laxative dosages-an approach with limited clinical utility. Non-pharmacological interventions, including dietary modification, physical activity, and health education, are safe and tend to have better patient adherence. The effectiveness of health education depends largely on message framing. Guided by information-framing theory, we developed an individualized non-pharmacological regimen.
