Causes of diabetes insipidus
Diabetes insipidus is a disease caused by deficiency
vasopressin, its relative or absolute deficiency.
Antidiuretic hormone (vasopressin) is produced in
the hypothalamus and, among other functions in the body, is responsible for
normalization of urination. According to etiological signs distinguish
three types of diabetes insipidus: idiopathic, acquired and

still remains unknown. Such diabetes is called –
idiopathic, they suffer up to 70 percent of patients.
Genetic is a hereditary factor. In this case
diabetes insipidus is sometimes manifested in several family members and in
generations in a row.
Medicine explains this by major changes in the genotype,
contributing to the occurrence of disruptions in the antidiuretic
hormone. Hereditary predisposition of this disease
due to a congenital defect in the structure of the intermediate and
Considering the causes of diabetes insipidus should
take into account the mechanisms of its development:
Central diabetes insipidus – develops with insufficient
vasopressin production in the hypothalamus or a violation of its release
from the pituitary to the blood, suggest that the causes are:
- Pathology of the hypothalamus, since it is responsible for the regulation

flu, sexually transmitted diseases, tuberculosis.
- Traumatic brain injury, concussion.
- Brain surgery, inflammatory
- Vascular lesions of the hypothalamic-pituitary system, which
lead to circulatory disorders in the arteries of the brain that feed
pituitary and hypothalamus.
- Tumor processes of the pituitary and hypothalamus.
- Cystic, inflammatory, degenerative kidney damage,
violating the perception of vasopressin.
- Autoimmune diseases
- Also hypertension is one of the aggravating factors
complicating the course of diabetes insipidus.
Renal diabetes insipidus – while vasopressin is produced
in normal amounts, but the kidney tissue does not respond to it
in due measure. The reasons may be as follows:
- Sickle cell anemia is a rare disease
- Congenital pathology is a hereditary factor
- Damage to the brain substance of the kidney or urinary tubules
- polycystic (multiple cysts) or amyloidosis (deposition in
amyloid tissue) kidney
- chronic renal failure
- increased potassium or decreased calcium in the blood
- medication that acts on the fabric

Лечение несахарного diabetes
Before prescribing treatment, it is necessary to clarify the diagnosis,

polyuria (increased urination) and polydipsia (thirst). For this
the patient is prescribed a comprehensive examination, including:
- Urinalysis with determination of density, sugar content
- To determine the daily amount of urine and specific gravity
(low with diabetes insipidus) conduct a test Zimnitsky
- The level of plasma antidiuretic hormone can be determined.

- For the differential diagnosis – test with dry milk.
Evaluation criteria for this sample are: the amount of urine released;
its relative density; body weight of the patient; his total
state of health; blood pressure level; pulse rate. If a
when conducting this sample, the amount of urine released
decreases, its proportion increases, blood pressure,
