Vasopressin has three main effects: 1  Increasing the water permeability of distal convoluted tubule and collecting duct cells in the kidney, thus allowing water reabsorption and excretion of more concentrated urine, i.e., antidiuresis.
Some of the complications of gastroparesis include: 1  Food that stays in the stomach too long can ferment, which can lead to the growth of bacteria.  Food in the stomach can harden into a solid collection, called a bezoar. Bezoars can cause obstructions in the stomach that keep food from passing into the small intestine.
When the body has too little enzymes available because our foods are dead, the body compensates by adding more digestive acid which can lead to gas, bloating and acid reflux. Without enough digestive enzymes food can sit in the stomach too long and contribute to bloating.
