Diabetes Insipidus

What is diabetes insipidus?

Diabetes insipidus occurs when your body doesn’t make enough antidiuretic hormone (ADH) or your kidneys don’t respond to it. ADH helps keep the right amount of water in your body. Normally, ADH controls how much urine your kidneys put out. This keeps you from losing too much water (being dehydrated). If you are a bit dehydrated, ADH should increase.

ADH is made by the hypothalamus, a small gland at the base of the brain. It is stored in the pituitary gland and then sent into the bloodstream as needed.

Diabetes insipidus is not related to the more common type of diabetes (diabetes mellitus).

What is the cause of diabetes insipidus?

There are several types of diabetes insipidus:

v  Central. This type occurs when the pituitary doesn’t make or send out enough ADH. It can happen if the hypothalamus or pituitary gland are damaged. This can be caused by a head wound (including surgery on the pituitary gland,) a genetic problem, and other diseases.



v  Nephrogenic. This type occurs when the kidneys don’t respond to normal levels of ADH. It can be caused by medicines or lifelong (chronic) disorders such as kidney disease or sickle cell disease.


v  Dipsogenic. This type occurs when there is damage to the mechanism that controls thirst, found in the hypothalamus. As a result you are too thirsty and drink too many fluids. This slows down ADH production.


v  Gestational. This occurs only in pregnant women. In this type, an enzyme made by the placenta destroys ADH in the mother.



What are the symptoms of diabetes insipidus?

Common symptoms may include:

l  Being very thirsty


l  Making too much urine


l  Dehydration


These symptoms may look like other health problems. Always see your healthcare provider for a diagnosis.


How is diabetes insipidus diagnosed?

Your provider will take your health history and give you a physical exam. You may also need the following tests:

ü  Urine tests


ü  Blood tests to see how your pituitary and kidneys react to dehydration (called a formal water deprivation test)



How is diabetes insipidus treated?

Your healthcare provider will figure out the best treatment for you based on:


Ø  Your age, overall health, and medical history


Ø  How sick you are


Ø  How well you handle certain medicines, treatments, or therapies


Ø  If your condition is expected to get worse



Ø  Your opinion or preference



Ø  Treatment for diabetes insipidus depends on what is causing it:


Ø  For central and gestational types, treatment may include taking modified ADH medicines or medicines to stimulate ADH production.


Ø  In nephrogenic diabetes insipidus, other medicines are used.


Ø  For all types, specific fluid intake is needed.


Ø  There is no known treatment for dipsogenic diabetes insipidus.



What are the complications of diabetes insipidus?

If you don’t drink enough fluids, you can get dehydrated. You can also have an electrolyte imbalance. This means not having the right balance of minerals in your body.

v  Dehydration can cause:


l  Dry skin


l  Dry mouth, nose, and sinuses


l  Fever


l  Rapid heart rate


l  Eyes can appear sunken


l  Weight loss


v  Electrolyte imbalance can cause:


l  Tiredness


l  Headache


l  Muscle pains



l  Feeling very tired


l  Being grouchy (irritable)


l  Irregular heartbeat



Living with diabetes insipidus

It’s important to follow your healthcare provider’s advice on medicines and fluid intake to prevent problems.


When should I call my healthcare provider?

If your symptoms get worse or you have new symptoms, call your healthcare provider right away.
