Causes of Nephrogenic Diabetes Insipidus
In nephrogenic diabetes insipidus (NDI), the kidneys are unable to respond to antidiuretic hormone (ADH), leading to excessive urination.
-
Mutations in genes (inherited forms)
-
Chronic kidney disease
-
Lithium or amphotericin B use
-
Unbalanced electrolytes (e.g., high calcium and low potassium)
-
Obstructive uropathy
Symptoms of Nephrogenic Diabetes Insipidus
Symptoms include:
-
Polydipsia (excessive thirst)
-
Polyuria (frequent urination)
-
Nighttime urination (nocturia)
-
Dehydration
-
Fatigue
-
Irritability
Diagnosis of Nephrogenic Diabetes Insipidus
Diagnosis involves:
-
A review of medical history and symptoms is performed
-
Checking electrolyte levels and kidney function with blood tests
-
Osmolality and concentration tests in urine
-
Testing the body's response to fluid restriction by depriving it of water
-
If hereditary NDI is suspected, genetic testing should be conducted
Nephrogenic Diabetes Insipidus Treatment
In addition to managing symptoms, treatment may include:
-
Preventing dehydration with adequate hydration
-
Reducing urine output with a low-salt, low-protein diet
-
NSAIDs or thiazide diuretics to decrease urine volume
-
Managing underlying conditions or medication use
Prevention of Nephrogenic Diabetes Insipidus
Among the preventive measures are:
-
Those at risk should have their kidney function and electrolytes monitored regularly
-
Medication that may cause or worsen NDI should be avoided
-
Supporting kidney health through a healthy lifestyle
-
Families with hereditary NDI may benefit from genetic counseling
