Challenges with DI and Desmopressin Management
My partner, who is 31 years old, has been facing multiple health issues including urinary incontinence, Overactive Bladder (OAB), frequent urinary tract infections (UTIs), and Chronic Pelvic Pain Syndrome (CPPS). Her treatment history is extensive; she has tried botulinum toxin injections, bladder hydrodistension, a variety of medications, and ultimately received a sacral neuromodulator/stimulator after these measures failed to provide relief. In September 2025, following several weeks marked by intense thirst (polydipsia) and excessive urination (polyuria) both during the day and at night, she was diagnosed with Central Diabetes Insipidus (CDI) and AVP deficiency. At its peak, she was consuming over 11 liters of water a day and producing an even greater volume of urine without intervention. Currently, she has been prescribed Desmopressin in varying doses (0.06/0.06/0.12), which has managed to alleviate most of her night-time urination. She generally takes one tablet approximately every four hours. However, her thirst remains a significant concern, with symptoms returning strongly as the medication effects diminish, leaving her experiencing crippling thirst, frequent bathroom visits, nausea, and a sensation of impending vomiting. This has severely impacted her ability to eat, as she is often overwhelmed with liquid intake, thus struggling to find a balance between hydrating and consuming food. By 6 p.m. each day, the noticeable decline in Desmopressin's effectiveness leads to the resurgence of these distressing symptoms alongside emotional and physical fatigue. The uncertainty of managing this condition has made her increasingly anxious and irritable, heightening her sense of helplessness. There’s also a concern that the Diabetes Insipidus may be compensating for and complicating the management of her OAB, putting additional strain on her treatments. The reality of our situation has become increasingly challenging over the past six months. In her last endocrinology appointment, when she inquired about next steps, the doctor merely shrugged and admitted uncertainty, which felt incredibly disheartening. As the weeks progress, her experience is becoming more difficult, affecting both her and our life together. We have reached out to the various medical professionals and specialists who have been involved in her care in the past, seeking guidance. Additionally, we have contacted local support groups for individuals with Diabetes Insipidus in hopes of connecting with others facing similar challenges regarding the effectiveness of Desmopressin and persistent thirst. At present, we are taking each day as it comes, but we wanted to share our story here, hoping it may connect us with someone who has navigated this path before. If you have experience with similar issues, are a specialist, or know someone struggling with Diabetes Insipidus, any advice or insight would be greatly appreciated!

Thank you for sharing your partner's challenges with Central Diabetes Insipidus (CDI) and its impact on her overall well-being. It sounds like she’s dealing with a lot, and it’s perfectly understandable to feel overwhelmed by the complexities of her health situation. Here’s a structured response to address her symptoms and management strategies effectively.
Main Points:
- Ongoing management of CDI is crucial to reduce thirst and improve quality of life.
- Finding a balance between hydration needs and dietary intake is essential.
- Emotional support and further exploration of treatment options can be beneficial.
Explanation:
Central Diabetes Insipidus occurs when the body doesn’t produce enough antidiuretic hormone (ADH), which regulates water balance. Desmopressin helps retain water in the kidneys, but its effects can wane, leading to symptoms like significant thirst and urination, as you've observed. The distressing thirst and nausea she feels, especially in the evenings, can be very difficult to manage, especially when it affects her ability to eat and rest.
Specific, Prioritized Next Steps:
-
Symptom Tracking: Keep a detailed log of her symptoms, including thirst levels, urine output, and any patterns related to Desmopressin. This data will be helpful for future discussions with her healthcare team.
-
Hydration Strategy: Encourage her to focus on smaller, more frequent sips of fluid rather than large quantities at once. This may help mitigate the intense thirst while making food intake more comfortable.
-
Evaluate Desmopressin Scheduling: Discuss with her healthcare provider the possibility of adjusting the timing and dosage of Desmopressin. Some patients find subdividing doses or taking a higher evening dose can stabilize overnight symptoms.
-
Addressing Rinse and Repeat Patterns: If intense thirst is only a later-day issue, confirm whether she could manage a slight increase in fluids earlier in the day while reducing evening intake. This could help balance her hydration and possibly lessen evening symptoms.
-
Dietary Adjustments: Consider a diet that includes hydrating foods (like fruits and veggies) to help maintain hydration levels. Consulting with a nutritionist familiar with her conditions may provide tailored meal planning.
-
Emotional and Psychological Support: It’s important to address the emotional strain this condition can cause. Support groups and counseling could be beneficial not only for her but for you as a partner. Sharing experiences and coping strategies can alleviate some feelings of helplessness.
-
Follow Up with Specialists: Given your partner's complex needs, seeking a second opinion from another endocrinologist or a specialist who focuses on DI may bring new insights or treatment options. You could also inquire about referral to a pain management specialist to discuss interactions between her CPPS, OAB, and DI.
-
Shared Decision-Making: Encourage her to actively participate in her care decisions, setting goals for what she hopes to achieve with her treatment. Clear communication with her healthcare team can help ensure her concerns are addressed in a more satisfactory way.
It’s commendable that you both are dedicated to navigating these challenges together. Finding practical solutions while working closely with healthcare providers can help improve her situation. Please don’t hesitate to reach out if you have further questions or need more support.

Seeking Interim Relief for Wrist Injury
Three weeks ago, I suffered a significant sprain to my wrist after a backward fall where I extended my arm, which caused a severe backward bend of my wrist. The following day, I experienced considerable swelling and pain, prompting me to visit urgent care. Fortunately, there were no new fractures detected, but I learned that my wrist had sustained previous injuries in the past. By the third day, the pain escalated, leading me to return to urgent care and subsequently to the emergency room, as advised. The sensation in my hand was alarming, feeling like it could burst from swelling, compounded by nerve pain akin to burning or being immersed in sulfuric acid. Despite having a high tolerance for pain, I found myself reacting uncontrollably, shaking and making unusual sounds. Unfortunately, the medical team could not alleviate the pain, and I exhausted my previously saved prescription narcotics from prior injuries—leaving none for future needs. At a weight of 150 pounds, I was taking roughly 40 mg of opioids just to manage the excruciating discomfort, which is an unusually high dose, even more than what is typically required post-orthopedic surgery. At present, I am experiencing sensations of numbness, tingling, and burning from my thumb to my ring finger, with my middle finger positioned awkwardly to the side. While some movement has gradually returned, and I can somewhat perceive temperature changes, I cannot feel touch or close my index and middle fingers. For lack of a better description, they feel almost non-functional. The pain intensifies at night, making it quite unbearable. I suspect my symptoms are indicative of carpal tunnel syndrome due to median nerve compression and tendonitis. The earliest appointment I could secure with a specialist is on March 2nd. Both urgent care and the emergency room practitioners recommended over-the-counter ibuprofen or acetaminophen, but I am looking for more immediate relief. In the meantime, are there any other measures I could or should consider? I've been engaging in range of motion exercises and alternating heat and ice treatments. However, if I run or elevate my heart rate, I begin to experience throbbing and burning sensations. Any insights or suggestions would be greatly appreciated.
Seeking Help for My Sister's Unbearable Pain: 11-Year-Old in Distress
Hello everyone, I’m reaching out for advice regarding my 11-year-old sister. Over the past month, she has been experiencing intense discomfort following urination, which has now extended to random moments throughout her daily routine as well. Unfortunately, there seems to be no identifiable cause or pattern to this distress. She spent a total of two weeks in one hospital and a few more days in another, undergoing extensive testing—MRIs, ultrasounds, various blood tests, and samples for urine and stool. Despite all these efforts, no clear answers have emerged, and her condition remains unchanged. Currently, she is being treated at home while on antibiotics, as doctors suspect a severe urinary tract infection might be the issue; however, they have not led to any improvement in her condition after two weeks. Additionally, she is taking pain relief medication, specifically diclofenac, which has proven ineffective despite her persistent suffering. Her pain levels fluctuate, but she consistently reports a baseline discomfort of 7 out of 10. There are moments of acute pain spiking to levels that can only be described as extreme, with her screaming in agony. The medical professionals have suggested that her ongoing pain could stem from a lack of estrogen, considering her prepubescent status, indicating she may continue to face this pain for another 18 months to 2 years. This prospect is understandably distressing for our family. To address this hormonal issue, she has been prescribed estrogen gel, but it may take a minimum of two weeks to see any effects, and there's no guarantee of success. This ongoing ordeal has taken a toll on my mother, who is overwhelmed and at her wit's end. We urgently need solutions; we can’t endure another four weeks of this situation. The impact of my sister's pain has kept her out of school and led her to miss out on contact with friends, leaving her morale quite low, and with no foreseeable end to her suffering. Any advice or shared experiences related to similar situations would be incredibly valuable and appreciated. Thank you!
Pain on the Outside of the Foot
Hello everyone, I've been experiencing discomfort on the outer part of my foot, particularly near the base of the fifth metatarsal. What's intriguing is that during my runs, once I warm up, the pain seems to dissipate or at least significantly lessen. However, post-run, the pain intensifies, especially when I compress or narrow my foot, as if I activate the outer edge. This area is sensitive when touched. Has anyone encountered a similar issue? In particular, I find that the first few steps in the morning are quite agonizing. To provide some background, I’m an avid runner (34 years old, female), in good shape, and I haven't suffered any noticeable injuries—just a gradual emergence of this discomfort. I had an X-ray done, ruling out a stress fracture. My typical runs range from 10 to 21 kilometers, and I've been doing this for several years without prior issues. I wear HOKA shoes, which have always worked well for me. I would welcome any advice or shared experiences related to this.
Help Me Banish This Cold
I’m a 17-year-old female dealing with a persistent cold and sinusitis that's just refusing to subside. Normally, I use cetirizine 5mg whenever I find myself in this situation, and it typically clears things up in about an hour (I really appreciate cetirizine!). Unfortunately, my current symptoms have escalated and lingered for a week now. Despite taking cetirizine daily, it seems ineffective this time. I've given a steamer a shot, which provides some relief, but it’s only temporary before I’m back to feeling completely congested and struggling to breathe through my nose. I also tried my Vicks inhaler, but its effects last only a few seconds. I’m desperate for suggestions to eliminate this irritating cold, as it’s driving me crazy!
Advice Needed After Boiling Water Burn
I am a 16-year-old and just experienced an unfortunate incident while preparing tea for bed. Approximately 15 minutes ago, I accidentally spilled boiling water on the back of my left hand—I didn’t douse the entire hand, just a portion of it. Since then, I’ve been trying to gather information and advice based on what I can find under these circumstances. Currently, I have my hand immersed in a bowl of cold water, but I’m uncertain about the next steps. How can I tell when it’s safe, and what should I do after this initial treatment? I'm alone right now, but I’m able to reach out for assistance here. However, I’m finding that each time I remove my hand from the cold water, it starts to feel mildly painful again within just five seconds. The information I’ve read varies widely, which adds to my confusion. My hand is definitely red and swollen but I haven’t noticed any blisters yet. It appears the swelling has decreased a bit since the initial incident. Can someone please guide me on how to protect my hand properly and what I should do as I try to get some rest? Thank you!
