- - - - Promximal dilation, distal decompress
        
        Abdominal distention by food, fluid, gas
        
        Increase intraluminal pressure
        
        Fluid sequestered into bowel
        
        Bowel oedema
        
        loss of fluid and electrolytes

        Decrease bowel's absorptive capacity
        
        Emesis
        
        Vessel compression
