SIADH vs Diabetes Insipidus DI | Endocrine System Nursing NCLEX

Share this:

SIADH vs Diabetes Insipidus (DI) for nursing endocrine system lecture exams and NCLEX review. This easy explanation on SIADH vs DI helps simplify the pathophysiology of diabetes insipidus and Syndrome of Inappropriate Anti-diuretic hormone. The key to understanding diabetes insipidus and SIADH is how the anti-diuretic hormone (ADH) works on the body. The ADH hormone is produced in the hypothalamus and secreted/stored in the posterior pituitary gland. ADH is responsible for retaining water in the body and constricting blood vessels. In SIADH, there is hypersecretion of ADH and hypo-secretion of ADH in Diabetes Insipidus. Learn more about the signs and symptoms and nursing interventions/management for SIADH and DI.

The pathophysiology of SIADH vs. DI both revolve around trauma to the pituitary.
SIADH, syndrome of antidiuretic hormone, is a condition where the body has stopped urinating leading to classic signs and symptoms of a swollen body, hemodilution (low serum osmolality “low liquidy labs”), and thick dark urine (high spec gravity).

DI, diabetes insipidus, is the opposite, where the body can not stop urinating, leading to classic signs and symptoms of dry body, hemoconcentration (high serum osmolality “high and dry labs”), and light diluted urine (low specific gravity).

This 7 part video series on endocrine medical surgical adult health nursing is intended to help registered nurse RN students and LPN students with NCLEX memorization tricks. In this video series Michael Linares, RN from Simple Nursing helps explain the nursing pathophysiology, signs and symptoms, causes, pathology, treatment options for various diagnosis, which are expected to know for the NCLEX, HESI, ATI, and Kaplan proctor exams.

  3. Shelly Morgan

    You have been a life saver! I'm studying for our Med Surg 1 final exam right now (REALLY dreading this test) & have been running through your videos because re-reading takes too long & it's impossible to remember everything in these textbooks. I only wish I knew about your channel before nursing school started. Thank you so much for taking the time out of your day to make these videos for us. So many students & nurses I've met all use you to help us get through this program. Thank You!

  4. Captain Velveeta

    Another good way to remember is;
    SIADH (lots of letters…lots of ADH…lots of water)
    DI (very few letters…very "few" ADH…very "few" water)
    …not grammatically correct but it helped me…good luck!

  5. Xavier Cobb

    You have gotten me through nursing school. I wish I could repay my student loans to you. Just want to say I really appreciate you.

  6. Andrew D. Harris

    They said I may have insipidus today, and I'd certainly believe it. I've survive some crazy stuff including traumatic brain injury. They sent me to an endocrinologist because I sweat, urinate, and drink so much. You should only need a sip of dis, but I'm so very thirsty. Thanks for your video. I'd first read of insipidus several years ago and said I needed to get checked because I have some problems. But, I couldn't get the nurse at the jail to read the grievances seriously, and then I forgot

  7. J J

    You’re helping me graduate. Been doing this for 3 years now and am almost done

  8. Into the Wilderness

  9. esther mumba

  10. Kang Sameda

    When you said that teas promote voiding, are you referring to all tea, or just tea with caffeine in it?

  11. Eagle775

    For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life. John 3:16 KJV, Jesus Christ is the only way……

  12. Carley Miller

    I find these videos so helpful, I review the material prior to my lecture class then just pay attending in class and watch these videos that cover what I’m learning to help reinforce all the information! Can you do a video on Dwarfism and Gigantism?

  13. Skorzeny

    Great content as always, can't tell you enough how helpful this is, so thanks!

  14. demp shin

    Hi, I am grateful for people such as yourself who take the time and (hopefully enjoy) teach the concepts – THE MNEMONICS ARE EXTREMELY HELPFUL with nursing school. There are many videos out here regarding these topics but yours are much easier to grasp for me. I am definitely a visual and auditory learner. Thank you!
    P.S. my textbooks suck when explaining these concepts.

  15. Kevin Cordovi

    you are the reason i pass my exams. marry me

  16. Benito Flores

    I tried to listen to other’s lectures but very complicated. Your explanation is amazing. It is easy to understand every detail. Your nclex package is really deserve the best. I am glad to find you. Thank you

  21. shanzel love

    Can you please explained the BMR TEST PLEASEEEE

  22. Captain Velveeta

    A way I like to remember is use the number of letters in the name:
    SIADH = lots of letters = lots of ADH = lots of water
    DI = less letters = less ADH = less water

  23. Divya Vadinkar

    In SIADH, if we add the sodium, isnt it gonna help retain more fluid into system? totally got confused.
    2) if desmopressin hold the U/O how its gonna cause hyponatramia?

  24. J C

    Coming back to this video again. How do you give it a double like? 😉

  25. Longlivechinny

    You don’t restrict your water intake on desmopressin right?

  26. DraTrix

    All videos helped a lot! Thank you

  27. April Thrasher

    For the last question you said further education would be needed for a patient that says "this drug is used to decrease my frequent urination," but I think that is a correct statement.

  28. jasmine wolf

    How would you cite this video using APA format?

  29. raven knight

    For the last question on desmopressin, isn’t option number three (3) excepted because the drug helps to retain fluid? This means the client don’t need further teaching right?

  30. Justin Charles

    at 14:55 you skipped I will make sure to restrict water intake" — with DI, this would be FALSE, because you are DI – Dry inside, you would want to increase water intake???? please reply thanks

  31. Matthew Ramirez

    So wait.. for the education 'pressin' question, Isnt the 3rd answer correct? Why would we select that one?

  32. Dilini Nandasena

    If salt follows water and water is retained by the body in siadh, why is there low sodium?

  33. Tan Tan

    Great resource for NCLEX!! But the last question confused me, my answer was 1,2,4 and 6. You skipped the 2 and chose 3 instead which is correct for DI. Anyway thank you for this video!!

  34. aly be

    I’m taking my NCLEX tomorrow and you just helped me lol, so let’s see how I do.
