Syndrome of inappropriate antidiuretic hormone (SIADH) and diabetes insipidus (DI) can confuse anyone because they are both endocrine disorders that involve the antidiuretic hormone (ADH).
It is easy to assume that diabetes insipidus is part of the diabetes mellitus family, but it is not. However, this endocrine disorder is caused by the hyposecretion of ADH. On the other hand, SIADH is caused by the body releasing an excess amount of ADH.
Would you be able to look at a lab value of serum sodium and see if it is consistent with SIADH? Do you know the treatment priority for diabetes insipidus?
To lose the confusion, here’s Sarah from RegisteredNurseRN.com giving a clear insight on the comparison of diabetes insipidus and SIADH.
