10.2 Constipation: Systems to Backtrace
Feline Fat-Based Metabolism (Fat-Based Metabolism)
Index page: constipation → backtrace variables → upstream food structure → related mechanism chapters.
Constipation is an observable output marked by straining, longer defecation intervals, dry hard stool, or difficult passage.
Constipation is not an independent root cause and cannot be reduced to drinking less water.
In Feline FBM, constipation belongs to Observable Output Backtrace. Backtrace should return to SGLT1-Mediated Water-Sodium Absorption, proximal small-intestinal water recovery, colonic propulsion, stool water content, and upstream food structure.
This page does not treat constipation as a cause and does not jump from output to treatment.
The degree of water recovery in the proximal small intestine affects how much water reaches the colon.
Exogenous Carbohydrate Load entry may strengthen SGLT1-Mediated Water-Sodium Absorption, increasing proximal recovery and reducing colon-available water.
Slower colonic propulsion extends residence time, further recovers water, and makes stool harder to pass.
The direct output variables are falling stool water content, higher formed density, and increased passage effort.
Food structure affects water-recovery paths and colonic propulsion through exogenous carbohydrate load, fat structure, protein and mineral structure, and feeding rhythm.
Urinary outputs backtrace Solute Load per Unit Energy; constipation backtraces the water-recovery path. The two cannot be unified as “drink more water.”
1. constipation = drinking too little water
2. constipation = add water and the problem is solved
3. constipation = too little material entering the colon
4. constipation = low residue alone
5. constipation = fiber supplement alone
6. constipation = isolated gut motility disorder
These readings skip output → water-recovery path → upstream food structure.
Marked pain, blood in stool, complete obstruction signs, or refusal to eat enter clinical handling.
Feline FBM is not a clinical diagnosis system, not a treatment protocol, and not an effect-guarantee system.
This index page lists backtrace variables and chapter entry points only.
