What Is Diabetes Insipidus?

5. Nephrogenic Diabetes Insipidus
Nephrogenic diabetes insipidus is the second type of this condition. It occurs when the body makes enough vasopressin, but the kidneys do not respond to it. This disconnect between the brain and the excretory system causes the kidneys to pull too much water from the blood stream and convert it to urine.
Like other forms of the illness, this type also is heritable in certain cases. Other factors that block vasopressin absorption include too much calcium or too little potassium in the blood, urinary tract blockage or kidney disease. Certain medications like lithium also can cause it.
