Although regular #2 toilet visits are a feature after this surgery, the frequency does reduce over time. Any weight that you lose after the surgery is easily regainable if your structure your diet to "slightly over your usual number of daily cals" - maybe 2250-2300 instead of a normal 2000.
The liquidity of your motoins can be lessened by eating a high fibre diet (to include pulverised fresh fruit + bran, pulverised fresh beg + bran, wholemeal bread etc etc). I liken this to mopping up a liquid spillage on the kitchen floor by throwing sawdust on the liquid in order to make it more semi-solid etc.
Removal of the colon is a big operation but I suspect that the discomfort and inconvenience of the operation will - over your lifetime - prove worthwhile compared to the propsect of "feeling less than 100%" due to chronic constipation.
