If using fiber supplements, take them at least 2 hours apart from other medications and meals. Start with low doses and increase gradually. Ensure adequate fluid intake (8+ glasses of water daily) to prevent GI obstruction. Monitor for worsening nausea, bloating, or constipation.
Why this interaction occurs
Soluble fiber supplements like psyllium husk significantly delay gastric emptying and slow intestinal transit. Semaglutide independently delays gastric emptying through GLP-1 receptor agonism. The combined effect can cause severe bloating, constipation, GI discomfort, and in rare cases, esophageal or intestinal obstruction. Fiber may also interfere with oral medication absorption timing.
Evidence
Evidence level: moderate.
