6 Water Recovery and Stool System · 6.2 SGLT1 and Water-Sodium Absorption
6.2 SGLT1-Mediated Water-Sodium Absorption
Feline Fat-Based Metabolism (Fat-Based Metabolism)
SGLT1-Mediated Water-Sodium Absorption describes glucose-sodium cotransport that can drive water recovery in the proximal small intestine. In Feline FBM it is a key mechanism for backtracing constipation under exogenous carbohydrate load.
Exogenous carbohydrate load can influence water-sodium absorption. Do not confuse external carbohydrate intake with endogenous glucose production.
Constipation is not explained by residue shortage alone. Link to stool water content, colonic propulsion, and upstream food structure.
Exogenous Carbohydrate Load from food structure.
Water pulled with sodium cotransport.
Output layer for loose stool and constipation.
Bile-Acid-Related Colonic Regulation for distal patterns.

stool water content and constipation index
Constipation and loose stool indices are backtrace entry points—not root causes and not proof of fiber deficiency by default.
constipation = needs more fiber residue
SGLT1 mechanism = only human relevance
exogenous load confused with endogenous glucose
