Diabetes Insipidus

OBJECTIVES After completing this article, readers should be able to: Describe the simple test that will establish the diagnosis of diabetes insipidus. Explain how to differentiate central diabetes insipidus from nephrogenic diabetes insipidus and compulsive water drinking. Delineate the inheritance pattern of central diabetes insipidus and nephrogenic diabetes insipidus. Describe the treatments of choice for central diabetes insipidus and nephrogenic diabetes insipidus. Definition and Epidemiology Polydipsia and polyuria with dilute urine, hypernatremia, and dehydration are the hallmarks of diabetes insipidus in infants and children. Patients who have diabetes insipidus are unable to conserve water and can become severely dehydrated when deprived of water. The polyuria exceeds 5 mL/kg per hour of dilute urine, with a documented specific gravity of less than 1.010. The hypernatremia is evidenced by a serum sodium concentration in excess of 145 mmol/L (145 mEq/L). Three conditions give rise to polydipsia and polyuria. The most common condition is central or neurogenic diabetes insipidus related to a deficiency of vasopressin. Less common is nephrogenic diabetes insipidus, including t Continue reading >>

    I guess most of these people have already given you good answers, but I want to reinforce it, since I have been a type I diabetic for almost 12 years.
    Type I diabetics can eat anything as long as they count the number of carbs in it and then take the appropriate amount of insulin to cover it. The only thing I don't do is drink regular (non-diet) pop.
    Maybe this person just happens to be diabetic and allergic to shellfish?

    Neonatal central diabetes insipidus (CDI) with or without adipsia is a very rare complication of various complex hypothalamic disorders. It is associated with greater morbidity and a high risk of developing both hypernatremia and hyponatremia, due to the condition itself or secondary to treatment with vasopressin analogs or fluid administration. Its outcomes have yet to be evaluated. All patients diagnosed with neonatal CDI in a university hospit ...

  • Why Do You Have Hypernatremia With Diabetes Insipidus?

    Print Overview Diabetes insipidus (die-uh-BEE-teze in-SIP-uh-dus) is an uncommon disorder that causes an imbalance of water in the body. This imbalance leads to intense thirst even after drinking fluids (polydipsia), and excretion of large amounts of urine (polyuria). While the names diabetes insipidus and diabetes mellitus sound similar, they're not related. Diabetes mellitus — which can occur as type 1 or type 2 — is the more common form of ...

  • Diabetes Insipidus Hypernatremia Treatment

    Hypernatremia is potentially life threatening and is caused by imbalances in water and sodium that occur from either water loss or sodium gain, often in the presence of inadequate water intake. The resultant hyperosmolarity, if acute or severe, can result in rapid shifts of water from the intracellular to extracellular space, causing intracranial hemorrhage and neurologic changes. Correction of hypernatremia through inappropriate fluid therapy c ...

    Physiology of Water and Body Fluids Disorders of sodium concentration result from a perturbation in water balance. Water is the most abundant body fluid. In lean individuals, water accounts for 60% of total body weight, with approximately two thirds residing intracellularly and one third in the extracellular space. Of the water in the extracellular space, approximately 75% is in the interstitium and 25% in the intravascular space. Because fat con ...
