So this weekend you heard from our friends @BukuRenal that mismanagement of IV fluids can cause harm.

A group we’d like to highlight who can come to serious harm from ⬆️/⬇️ fluids is patients with

💦DIABETES INSIPIDUS 💦

See below 👇

Diabetes insipidus (DI) is the inability to hold onto water due to lack of /resistance to ADH.

Remember ADH is released as serum osmolality ⬆️ to ⬆️ renal water reabsorption, but in patients with DI this doesn’t occur and so they pass large vol watery urine - can be >10L/day!🛁

Note diabetes insipidus has nothing to do with glucose/sugar like diabetes mellitus! ⛔️❌⛔️

Misunderstandings are so common (even with HCPs) that there is a campaign to change the name to "pituitary insipidus"

#NoTimeToDI

Cranial DI (ADH not released) is usually due to pituitary/hypothalamic surgery, infiltration (inflammation/malignancy - rare) or head trauma. Can also be genetic.

Pituitary adenomas themselves can cause lots of hormone dysfunction, but don't typically cause DI.

Nephrogenic DI (ADH resistance) can be caused by
- renal disease
- electrolytes (⬇️ K, ⬆️ Ca – hence why hyperCa is dehydrating)
- drugs - can be seen with up to 15% of people taking LITHIUM 💊
