Final answer:
Diabetes insipidus is caused by a deficit of Antidiuretic Hormone (ADH). ADH involves in regulating the body's water balance. This deficit can lead to frequent urination, excessive thirst, and even potentially dangerous electrolyte imbalances in severe cases.
Step-by-step explanation:
The hormonal imbalance that causes diabetes insipidus is a deficit of ADH (Antidiuretic Hormone). ADH, also known as vasopressin, is a hormone produced in the hypothalamus and released by the posterior pituitary gland. Its primary function is to regulate the body's water balance by controlling the amount of water excreted by the kidneys.
In diabetes insipidus, there is a chronic underproduction of ADH, which results in the kidneys being unable to retain water. This leads to frequent urination and increased thirst. If not managed, severe cases can lead to electrolyte imbalances due to dehydration. Regardless of the amount of water consumed, it will be lost again due to the inability of the kidneys to reabsorb water effectively because of the low levels of ADH.
