The number of new cases of diabetes insipidus each year is 3 in 100,000. [4] Central DI usually starts between the ages of 10 and 20 and occurs in males and females equally. [2] Nephrogenic DI can begin at any age. [3] The term "diabetes" is derived from the Greek word meaning siphon. [6]
Diagnosis is based on clinical and laboratory findings of low serum osmolality and low serum sodium. [13] Urinalysis reveals a highly concentrated urine with a high fractional excretion of sodium (high sodium urine content compared to the serum sodium). [14] A suspected diagnosis is based on a serum sodium under 138.
Untreated central diabetes insipidus patients usually exhibit polyuria, nocturia, and polydipsia as a result of the initial rise of serum sodium and osmolality. [5] Patients may also experience neurologic symptoms associated with the underlying illness, such as headaches and diplopia, depending on the exact origin of the central diabetes insipidus.
What is diabetes insipidus? You’re no doubt aware of diabetes mellitus, which has type 1 and type 2 variations. It’s a disorder of water balance and control in the body, explains Christopher ...
Differential diagnosis includes nephrogenic diabetes insipidus, neurogenic/central diabetes insipidus and psychogenic polydipsia. They may be differentiated by using the water deprivation test. Recently, lab assays for antidiuretic hormone are available and can aid in diagnosis.
X-linked nephrogenic diabetes insipidus type 1 [304800] V2 receptor: Xq28: XR: Hyperthermia, polyuria, polydipsia, dehydration, inability to form concentrated urine, intellectual disability if diagnosis delayed. Symptoms in infancy: Hyperosmolar plasma, dilute urine Autosomal dominant nephrogenic diabetes insipidus type 2 [192340] AQP2: 12q13 ...
Adipsia, also known as hypodipsia, is a symptom of inappropriately decreased or absent feelings of thirst. [1] [2] It involves an increased osmolality or concentration of solute in the urine, which stimulates secretion of antidiuretic hormone (ADH) from the hypothalamus to the kidneys.
[18] [47] [48] This condition affects around 70% of the patients with WSF1 mutation (WFS2 mutation does not typically associate with diabetes insipidus). [10] [15] Diabetes insipidus occurs around the age of 14 but the condition is often diagnosed late. Therefore, there is a high variability in the onset age.
