Diabetes mellitus versus diabetes insipidus and a common factor: polyuria. Case presentation

Abstract

Diabetes mellitus is a non-transmissible chronic disease, very 
frequent in the city of Matanzas, which is present in any age group, 
and is classified as type I and type II. In the type I diabetes, the 
body does not produce insulin. In the type II diabetes, the most 
common one, the body does not produce or does not use it effectively.  Without enough insulin, glucose remains in the blood, causing several complications, both acute and chronic. The diabetes insipidus is a few common disorder of the water metabolism. That means that the balance  between the quantity of water or any other fluid someone drinks does not coincide with the volume of the urinary excretion. It is due to a  lack of answer or a deficient answer to the anti-diuretic hormone  vasopressin. This hormone controls the water balance through the urine  concentration.  The patients with diabetes insipidus urinate a lot, so they need to drink many liquids to replace those they lose. It is  presented the case of a patient aged 45 years, with health antecedents, that debuted with diabetes insipidus and a year later with a concomitant type II diabetes mellitus. The complementary tests  confirmed that and the patient got better with the treatment.
