We observed a striking case involving a 76-year-old woman diagnosed with cervical cancer, who was treated with nedaplatin, a platinum-based chemotherapy drug. Shortly after starting her treatment, she experienced troubling symptoms, including numbness, dizziness, and a noticeable loss of appetite.
Upon investigation, we discovered low levels of calcium and magnesium in her blood, which were likely contributing to her symptoms. Thankfully, after administering intravenous calcium and magnesium, we saw a prompt improvement in both her mineral levels and her symptoms.
The case underscores the importance of monitoring electrolyte levels during chemotherapy treatments, such as nedaplatin. By focusing on these disturbances, healthcare providers can unveil potential diagnoses even when patients present with vague symptoms. Regular follow-ups during anticancer therapies could be crucial in effectively managing side effects such as dizziness.

We observed a unique case of a 35-year-old woman experiencing non-traumatic multicanal benign paroxysmal positional vertigo (BPPV). Initially diagnosed with unilateral posterior canal BPPV, her condition evolved to include both horizontal and anterior canals over time.
Throughout 2012 to 2014, conventional treatments fell short in resolving her symptoms, despite her undergoing canalith repositioning treatments (CRTs). Remarkably, in 2015, we noted a correlation between her self-treatment of vitamin D—at a dose of 5000 IU daily—and the subsequent resolution of her vertigo symptoms.
This case stands out not just because of the uncommon progression from single-canal to multi-canal BPPV, but also highlights the potential role of vitamin D in symptom management. It suggests that vitamin D might offer benefits for those suffering from dizziness related to vertigo, particularly in cases where traditional treatments are ineffective.

We explored the connection between serum vitamin D levels and the recurrence of benign paroxysmal positional vertigo (BPPV), a leading cause of dizziness. In this study, we reviewed the medical charts of 50 patients diagnosed with BPPV, focusing on two distinct groups: those who experienced recurring episodes and those who did not.
Our findings revealed that the average serum vitamin D level in patients who had recurring BPPV was significantly lower (12.9 ng/mL) compared to those without recurrences (19.2 ng/mL). This suggests that lower vitamin D levels might be linked to a higher chance of dizziness from BPPV recurrences.
We also identified that a vitamin D level below 12.74 ng/mL was associated with a significantly higher recurrence rate of 70.5%, compared to just 22.5% for those above this threshold. This indicates that monitoring and managing vitamin D levels could be crucial for patients at risk for recurring episodes of BPPV.
In summary, our findings underline the potential importance of vitamin D in managing dizziness, particularly in individuals suffering from BPPV. It seems that keeping an adequate level of this vitamin might help reduce the risk of future vertigo episodes.

Improved dizziness

Great! Firstly, it's a substantial dosage, which makes it easy to take. Despite being a large pill, I've found it easy to swallow. The ingredients are decent and quite suitable for my age group. I feel more energetic, and my dizziness appears to have improved.

This product gave me migraines and made me very dizzy. A friend suggested taking this or the multivitamin, not both. I chose to continue with my multivitamin and discontinued this product...resulting in my migraines and dizziness going away. It just didn't suit me well.

We explored the connection between vitamin D deficiency and dizziness following a successful left-sided stapedotomy. In our case study, a 56-year-old woman who underwent the stapedotomy for otosclerosis experienced postoperative dizziness a week later. Interestingly, this dizziness occurred mainly when she turned to her left side while lying in bed.
To understand her condition better, we conducted an electrophysiological assessment of her vestibular function, which revealed a typical response associated with benign paroxysmal positional vertigo (BPPV). Notably, we found that the patient had a deficiency in vitamin D levels in her serum.
After a 7-day treatment using Epley's maneuver, which is a common approach for BPPV, the patient's symptoms resolved completely. This highlights the importance of recognizing BPPV as a potential complication after stapes surgery, especially when vitamin D levels are low.
Our findings suggest that monitoring serum levels of total calcium and vitamin D could be crucial not only for understanding dizziness but also in preventing its recurrence after such surgeries.

We observed the intriguing connection between Meniere's disease (MD) and migraine-related dizziness in our study of a 5-year-old girl. She experienced a six-month struggle with left-sided hearing loss, which evolved into daily bouts of vertigo, headaches, and vomiting, fulfilling the criteria for definite MD.
After implementing a specialized six-week migraine diet and lifestyle plan that included riboflavin and magnesium, we noted a remarkable transformation. The child became symptom-free and achieved nearly normal hearing levels, leading us to consider that MD symptoms might be linked to vestibular migraine triggers.
This suggests that young patients with MD could greatly benefit from lifestyle and dietary adjustments aimed at managing migraine symptoms. While magnesium was part of this regimen, it’s essential to look at it as one component of a broader approach. The results invite further exploration into how dietary interventions may alleviate both cochlear and vestibular symptoms in Meniere's disease.

We looked into the issue of persistent post-stapedotomy vertigo, or PSV, which can leave patients feeling dizzy for months after ear surgery. Over a span of ten years, we examined cases at a major hospital where patients reported ongoing dizziness for at least three months following their procedure.
Our findings included five patients who struggled with daily vertigo episodes, averaging 53 years old. They were treated with a combination of lifestyle and dietary changes alongside medications like nortriptyline and verapamil. Interestingly, vitamin B2 and magnesium were also part of the regimen.
After starting treatment, we noticed a remarkable turnaround. All five patients experienced a complete resolution of their vertigo over an average period of nine weeks. While magnesium was included in their treatment, we cannot definitively point to its isolated effect on dizziness, as it was used alongside other medications. Overall, our results hint that patients suffering from this type of vertigo might indeed benefit from migraine prophylaxis treatments, where magnesium could play a role, but more research is needed to isolate its impact specifically.

We investigated how Vitamin D levels impact dizziness, specifically in individuals with Benign Paroxysmal Positional Vertigo (BPPV). This condition causes sudden episodes of vertigo, often triggered by changes in head position.
In our study, we enrolled 100 patients diagnosed with BPPV and measured their Vitamin D levels. Based on these measurements, we classified participants as having deficient, insufficient, or sufficient Vitamin D levels. Those with deficiencies received Vitamin D supplementation of 2000 IU daily for six months.
Over the course of a year, we followed these patients monthly, monitoring both the frequency and severity of their BPPV episodes using the Vertigo Symptom Scale. Our findings were quite significant: those with Vitamin D deficiency experienced BPPV at a rate of 71%, compared to only 20% in those who had sufficient Vitamin D levels. Moreover, the severity of vertigo symptoms was notably higher in the deficient group.
Importantly, we observed that supplementation appeared to reduce both the incidence and severity of BPPV episodes over time. This highlights the potential role of Vitamin D in supporting vestibular health and suggests it may be a valuable component of managing BPPV. However, further controlled studies are needed to fully understand these connections and their implications for patient care.
