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 disorder that slows or stops the movement of food from the stomach to the small intestine. It occurs when the vagus nerve (which controls the stomach muscles) is damaged by illness or injury so the stomach muscles can no longer function properly and digest food. The most common symptoms of gastroparesis are nausea, a feeling of fullness after only eating a small amount of food and vomiting undigested food. It can also cause issues with reflux, bloating, stomach pain and lack of appetite.
