How imbalanced electrolytes can throw off everything in your body.
A client recently came to me with repeated fainting episodes and intermittent high blood pressure. I’ll call him Jim. During these episodes he became extremely dizzy and nearly lost consciousness. When checked, his blood pressure was elevated.
At the doctor’s office he was told the events were cardiovascular and a statin was offered without first doing a comprehensive cholesterol panel. Jim sought a blood chemistry session with me, where I recommended a detailed NMR lipid profile. The results were, at first glance, reassuring.
His lipids suggested he was stressed (a slight rise in LDL-P/apoB), could benefit from more omega fats (a small increase in small LDL), and was likely under-consuming calories and healthy fats (low triglycerides). Those clues—stress and under-eating—helped point the next steps.
Reviewing the broader bloodwork using functional ranges revealed a clear pattern:
- High albumin
- High hemoglobin
- High red blood cell count (RBC)
- High blood urea nitrogen (BUN)
- Low sodium
- High potassium
- Low alkaline phosphatase
This constellation of results is a classic chronic dehydration pattern often tied to long-term stress and mitochondrial dysfunction—sometimes referred to as adrenal dysfunction. In Jim’s case, chronic stress and under-fueling appear to have impaired cellular energy production and the adrenal-related regulation of sodium and potassium.
What likely happened is prolonged stress causing mitochondrial strain and reduced aldosterone production (the adrenal hormone that helps regulate sodium and potassium). With lower aldosterone, the body struggles to hold on to sodium and maintain the normal sodium-potassium balance. During an episode the body compensates, activating systems that raise blood pressure through the renin-angiotensin-aldosterone system (RAAS), which can create spikes in blood pressure and symptom episodes that repeat as long as the underlying stress and imbalance persist.
This cycle—dehydration from stress and stress from dehydration—can become self-perpetuating and progressively worsen symptoms over time.
Common signs that this pattern may be affecting you include:
- Persistent fatigue
- Anxiety or heightened stress
- Feeling overwhelmed
- Shakiness
- Frequent headaches
- Swelling or edema
- Brain fog
- Dizziness
Understanding Electrolytes
Electrolytes such as sodium and potassium play central roles in fluid balance and adrenal function. Sodium largely determines blood volume and pressure because water follows sodium; changing sodium levels shifts extracellular fluid volume and thus affects blood pressure and nutrient absorption. Sodium is primarily an extracellular ion.
Potassium is mainly intracellular—about 98% of the body’s potassium is inside cells. Potassium influences cellular pH, nerve firing, and muscle contraction, and it works together with sodium on the sodium-potassium pump. Maintaining the right balance between sodium and potassium is essential for normal cellular and cardiovascular function.
The Role of Adrenal Health in Sodium/Potassium Balance
The renin-angiotensin-aldosterone system (RAAS) regulates blood volume and pressure. When activated—by low sodium, low blood pressure, or high cortisol—RAAS increases angiotensin II and stimulates aldosterone release from the adrenals. Aldosterone promotes sodium and water retention while increasing potassium excretion, which raises blood volume and pressure. Chronic stress elevates cortisol and can therefore drive RAAS activity, linking stress to higher blood pressure.
Next Steps for Jim (and for you!)
Standard blood work can reveal the dehydration pattern, and it’s one of the more actionable findings in clinical practice. Fixing it usually involves more than water alone: the right electrolyte balance is necessary so water can properly hydrate cells and restore normal physiology.
For many people, targeted electrolyte supplementation, along with lifestyle adjustments, provides meaningful improvement. Rebalancing sodium and potassium to support cellular hydration, supporting the adrenals by reducing chronic stress, ensuring adequate calorie and healthy fat intake, and stabilizing daily routines are critical elements of recovery.
In Jim’s case, skipping meals, a fast-paced lifestyle, and a low-sodium diet likely made his symptoms worse. He benefited from correcting electrolyte intake, prioritizing nourishing meals with healthy fats, and reducing constant high-level stress. These changes aim to restore mitochondrial function, support aldosterone balance, and break the cycle of dehydration and pressure spikes.
Addressing electrolytes and underlying stressors is often a straightforward, effective approach to improving symptoms like dizziness, fatigue, and blood-pressure lability. If you suspect a similar pattern, consider discussing a focused bloodwork review and a plan that includes electrolyte balance, consistent nutrition, and stress reduction with a qualified practitioner.
Try improving hydration with a balanced approach to electrolytes, eat regular nutrient-dense meals, and prioritize rest and stress management to support long-term recovery.
