WebOct 21, 2024 · Since the clinical trials defined hyponatremia as a decrease in serum sodium level identified through laboratory monitoring, this risk may not be clinically relevant. WebArginine vasopressin is produced by the posterior pituitary gland. It acts upon the kidneys to cause them to retain water. This is a very important mechanism to prevent dehydration. Too much vasopressin can cause the kidneys to hold too much water, diluting out the sodium level in the bloodstream.

ADH keeps the amount of water in your body in balance. Certain conditions can affect the amount of ADH that your body makes. These include hyponatremia, or low sodium levels in your bodily fluids. They also include diabetes insipidus. Symptoms of this condition include urinating often and being very thirsty.
WebVasopressin regulates the amount of water reabsorbed by the kidneys, and without it, the kidneys excrete large amounts of diluted urine, resulting in dehydration and electrolyte imbalances. On the other hand, SIADH is a condition in which the body retains too much water, leading to low levels of sodium in the blood.
