6.5 Stool Water Content

Feline Fat-Based Metabolism (Fat-Based Metabolism)

Definition

Stool water content is a direct output variable for both loose stool and constipation. It should be backtraced into water recovery, colonic propulsion, colonic secretion, and upstream food structure.

Loose stool: stool water content increases and/or formation decreases. Constipation: stool water content decreases and/or output resistance increases.

Stool water content is the output layer, not a root cause. Do not jump from stool form directly to treatment.

Control Variables
1. Proximal small-intestinal water recovery

Upstream water-handling basis.

2. SGLT1-mediated water-sodium absorption

SGLT1-Mediated Water-Sodium Absorption under carbohydrate load.

3. Colonic secretion

Secretion increases luminal water.

4. Colonic propulsion

Transit time changes final water content.

5. Fat processing rate

Fat Processing Rate links digestive handling to colonic inputs.

Observable Outputs

Loose stool index and constipation index read stool water content and resistance patterns as backtrace entry points—not as diseases by default.

stool water content = drinks too little or too much

Page duty

This page defines stool water content as output variable only. Not a clinical diagnosis system, not a treatment protocol, not an effect-guarantee system.
