Perspective · Regulation · Aug 25, 2026
Permeability is not the problem. Dysregulation is.
Health lies less in maintaining a fixed state than in a system’s capacity to regulate, adapt and recover. Intestinal permeability provides a biological starting point for asking when a response is appropriate—and when regulation becomes dysregulation.

The intestinal barrier is not a wall.
Living Boundaries concerns the health of communication: how a boundary receives, sets limits and adapts according to context. The intestinal barrier is the biological starting point for that larger question.
