What Are the Common Causes and Risk Factors?
Understanding central diabetes insipidus seniors is important for seniors and their caregivers.
Diabetes insipidus (DI)
is an uncommon condition in which the kidneys are unable to prevent the excretion of water. DI is a different disease than
diabetes
, though both share common symptoms of
excessive urination
and thirst.
Central diabetes insipidus is a form of DI that occurs when the body has a lower than normal amount of antidiuretic hormone (ADH). ADH is also called vasopressin. ADH is produced in a part of the brain called the
hypothalamus
. ADH is then stored and released from the pituitary gland. This is a small gland at the base of the brain.
ADH controls the amount of water excreted in urine. Without ADH, the kidneys do not work properly to keep enough water in the body. The result is a rapid loss of water from the body in the form of dilute urine. This results in the need to drink large amounts of water due to extreme thirst and to make up for excessive water loss in the urine (10 to 15 liters a day).
The reduced level of ADH may be caused by damage to the hypothalamus or pituitary gland. This damage may be due to surgery, infection, inflammation,
tumor
, or
injury to the brain
.
In rare cases, central diabetes insipidus is caused by a genetic problem.
What Are the Symptoms and Warning Signs?
Symptoms of central diabetes insipidus include:
- Increased urine production
- Excessive thirst
- Confusion and changes in alertness due to dehydration and higher than normal sodium level in the body, if the person is unable to drink
📖 What Are Exams and Tests?
What Are Exams and Tests?
Your health care provider will ask about your medical history and symptoms.
Tests that may be ordered include:
-
Blood sodium
and
osmolality
- Desmopressin (DDAVP) challenge
-
MRI of the head
-
Urinalysis
-
Urine concentration
and osmolality
- Urine output
📖 How Is It Treated?
How Is It Treated?
The cause of the underlying condition will be treated.
Vasopressin (desmopressin, DDAVP) is given either as a nasal spray, tablets, or injections. This controls urine output and fluid balance and prevents
dehydration
.
In mild cases, drinking more water may be all that is needed. If the body’s thirst control is not working (for example, if the hypothalamus is damaged), specific instructions to the person for a certain amount of water intake may also be needed to ensure proper hydration.
📖 What Is Outlook (Prognosis)?
What Is Outlook (Prognosis)?
The outcome depends on the cause. If treated, central diabetes insipidus usually does not cause severe problems or result in early death.
📖 What Are Possible Complications?
📖 When to Contact a Medical Professional?
When to Contact a Medical Professional?
Contact your provider if you develop symptoms of central diabetes insipidus.
If you have central diabetes insipidus, contact your provider if frequent urination or extreme thirst returns.
📖 How Is It Prevented?
How Is It Prevented?
Many of the cases may not be preventable. Prompt treatment of infections, tumors, and injuries may reduce risk.
