6.1 Proximal Small Intestinal Water Recovery

Feline Fat-Based Metabolism (Fat-Based Metabolism)

Definition

Proximal small-intestinal water recovery affects how much water remains available for later intestinal segments. It is an upstream water-handling control variable in constipation backtrace.

Water recovery is not the same as drinking water. Upstream intestinal recovery sets the stool water basis before colonic propulsion and secretion variables act.

Do not explain constipation only as “not drinking enough.” Link recovery to SGLT1-Mediated Water-Sodium Absorption and upstream food structure.

Control Variables
1. SGLT1-mediated water-sodium absorption

SGLT1-Mediated Water-Sodium Absorption drives cotransport-linked water recovery.

2. Exogenous carbohydrate load

Exogenous Carbohydrate Load influences proximal handling.

3. Stool water content

Downstream output variable for backtrace.

4. Colonic propulsion

Later-segment variable after proximal recovery.

Causal Chain

Observable Outputs

Constipation index and stool hardness patterns backtrace through recovery variables—not through water bowl volume alone.

constipation = drinks too little by default

proximal recovery = drinking water intake
