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.
Points to Remember. 1  Gastroparesis, also called delayed gastric emptying, is a disorder that slows or stops the movement of food from the stomach to the small intestine. 2  Gastroparesis can occur when the vagus nerve is damaged by illness or injury and the stomach muscles stop working normally. Food then moves slowly from the stomach to the small intestine or stops moving altogether.
