Question
In a disease called diabetes insipidus, ADH activity is insufficient. Would a person with this disease produce more or less urine than normal? Explain.
Step 1
ADH is produced in the hypothalamus and is responsible for controlling the water levels in the body. It does this by signaling the kidneys to conserve water and reduce the amount of urine produced. Show more…

Diabetes INSIPIDUS is a disease affecting ADH secretion, in which too much urine is produced ("polyuria"). A person is constantly very thirsty and drinks ridiculous amounts of water. a. Is this too much ADH or too little ADH? b. Explain why this pathology would cause excess urine production. Be specific: talk about the reabsorption of water at the kidneys; how it is accomplished; and how ADH plays a role (and why this problem with ADH causes polyuria!)
Both diabetes mellitus and diabetes insipidus produce large urine volumes, but how would other characteristics of the urine differ between the two diseases?
Persons with uncontrolled diabetes mellitus can have very high levels of glucose in their blood. Why do such individuals have a high level of urine production?
