How to check diabetes insipidus

summary

Diabetes insipidus is a common disease. Patients with diabetes insipidus can usually show a series of adverse symptoms such as diabetes insipidus, polyuria, dry mouth and dry skin. Now let's talk about how to check diabetes insipidus.

How to check diabetes insipidus

First: assessment of plasma osmolality and urine osmolality. The relationship between plasma osmolality and urine osmolality was normal. If the osmolality of blood and urine measured several times in a polyuria patient falls to the right side of the shadow, the patient has central diabetes insipidus or renal diabetes insipidus.

Second: water ban test. It is a simple and feasible method to compare the urine osmotic pressure after water deprivation with that after using vasopressin to determine diabetes insipidus and to distinguish the deficiency of vasopressin from polyuria caused by other reasons. This test is used to evaluate urinary osmolality and is often used in combination with osmolality relationship 15-21.

Third: hypertonic saline test. This test is rarely used in the diagnosis of diabetes insipidus. It can be used when it is necessary to prove the change of osmotic pressure threshold of AVP release, and it has certain value in analyzing some characteristics of hyponatremia and hypernatremia.

matters needing attention

Patients with diabetes insipidus disease because of this disease seriously affected the normal life of patients, so patients found that they have this disease, to timely treatment, active treatment, so that the condition can be effectively alleviated.
