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.
Other health issues that can cause stomach distension are celiac disease, diverticulitis, abdominal tumor, intestinal disorder, cyst in the ovary, cancerous growth in the ovary, fibroids in the uterus, and increase in the accumulation of fluid inside stomach, increased acidity and malnutrition.
