Consumption by a dog or cat of more than 100 ml of water per kilogram of body weight per day and constant urge to urinate is the primary marker of a malfunction of the hypothalamic-pituitary system. A sharp drop in the level of antidiuretic hormone deprives the renal tubules of the ability to concentrate urine, triggering the process of rapid tissue dehydration.
The lack of timely medical intervention leads to blood clots, critical disruption of the water-electrolyte balance and hypernatremia. Early diagnosis of functional disorders of the endocrine system makes it possible to select replacement therapy and fully restore plasma osmolality.
Pathogenesis and causes of vasopressin deficiency
The central form of the disease develops against the background of mechanical damage to the pituitary gland or structural changes in brain tissues. Traumatic brain injuries, viral infections, and benign adenomas destroy the neurons responsible for peptide hormone synthesis.
In veterinary practice, a nephrogenic type of pathology is also recorded, in which hormone production remains normal, but kidney receptors lose sensitivity to it. Collecting a primary medical history requires strict fixation of the volume of liquid consumed:
- the owner isolates the animal from outdoor puddles and open reservoirs;
- within 24 hours, water is poured strictly from a measuring cup;
- the number of urinations and the volume of fluid secreted are recorded.
Accurate calculation of the amount consumed allows the veterinarian to distinguish true polydipsia from psychogenic thirst. The exclusion of diabetes mellitus and chronic renal failure is carried out before the start of specific non-targeted tests.
Differential diagnosis and monitoring of urine specific gravity
The clinical examination begins with a biochemical blood test to assess the level of creatinine, urea and electrolytes. Measurement of urine density using a veterinary refractometer demonstrates isosthenuria - the specific gravity drops below 1.008, which directly indicates the absence of filtration moisture retention.
The fluid deprivation test is performed exclusively in a hospital setting under continuous cardiac monitoring due to the risk of hypovolemic shock. The protocol includes strict steps:
- complete restriction of pet's access to water for a period of eight to 12 hours;
- hourly emptying of the bladder through a catheter to assess density;
- subcutaneous injection of a synthetic vasopressin analogue with a loss of 5 percent of body weight.
A sharp jump in urine concentration after injection of desmopressin unmistakably confirms the central genesis of the disease. The lack of reaction to the drug indicates renal immunity, requiring the use of thiazide diuretics.
Substitution therapy protocols and stabilization of the condition
Treatment of central diabetes insipidus is based on lifelong use of desmopressin in the form of eye drops, tablets or nasal spray. The starting dosage is calculated based on the weight of the pet, and then titrated by a veterinary endocrinologist until the symptoms of polyuria completely disappear. The cost of a monthly course of drugs varies from 2000 to 5000 rubles, depending on the form of release and the weight of the animal.
The owner is obliged to arrange uninterrupted access to clean drinking water, as an accidental omission of medication instantly resumes fluid loss. Dietary adjustments include switching to industrial feed with a reduced sodium content to reduce the osmotic load on the renal glomeruli.
Routine medical check-up is carried out every six months and includes ultrasound of the abdominal cavity, as well as monitoring of sodium levels in the blood serum. A well-chosen treatment regimen stops the threat of water intoxication and allows a pet to lead a full-fledged lifestyle without restrictions on physical activity.
