Hi, I’ve recently had some abnormal tests and been referred to a Nephrologist. Im concerned it may be diabetes insipidus. Ive been taking Lithium for over 10 years, so Im afraid thats what is causing this. Most symptoms and labs steer toward this diagnosis, but not all. Testing for diabetes mellitus came back normal. Does anyone know anything about DI? I’m very frustrated as I do not see the specialist for another month. Nothing else really fits….no blood or protein in urine. Urine osmality low but serum is normal. Low gfr, ,low serum potassium, slighty elevated creatinine, and several 24hr urine test results were off. I drink a lot, preferably cold drinks. Pee often, and just recently wet the bed a few times. Ive had dry mouth, thirst for years, but didn’t think anything of it until I started to get low gfr numbers recently, then thought I should seek another opinion. Im just kind of lost. Whatever it is or isnt, i just want to know. I have other health problems. Making me nervous, feel like dead weight right now, bracing for impact.
