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.
Gastroparesis is a long-term (chronic) condition where the stomach can't empty itself in the normal way. Food passes through the stomach more slowly than usual. It's thought to be the result of a problem with the nerves and muscles controlling the emptying of the stomach. If these nerves are damaged, the muscles of your stomach may not work properly and the movement of food can slow down. This page covers: Symptoms of gastroparesis.
