Hypovolemic hyponatremia
Hypovolemic hyponatremia
Low sodium levels due to decreased blood volume from renal and non-renal causes.
Hypervolemic hyponatremia
Hypervolemic hyponatremia
Occurs when sodium is diluted in excess of water in the body.
Hypernatremia
Hypernatremia
High sodium levels, typically from excess sodium intake or body water loss.

Study Notes
Electrolyte Imbalances
- Hypovolemic Hyponatremia:
- Renal causes: adrenal insufficiency, osmotic diuresis, diuretic use
- Non-renal causes: excessive sweating (diaphoresis), vomiting (V/D)
- Characterized by low sodium levels in the blood due to lower total body water.
- Hypervolemic Hyponatremia:
- Sodium diluted in excess water
- Hypernatremia:
- Excess sodium in the bloodstream or decreased body water.
- Most common cause: decreased body water.
- Hypokalemia:
- Caused by diuretics, renal stress, metabolic alkalosis, high aldosterone levels, vomiting, diarrhea.
- Low potassium levels in the blood.
- Hyperkalemia:
- Main cause: kidney failure.
- High potassium levels in the blood.
- Hypocalcemia:
- Low calcium levels in the blood due to insufficient calcium in diet, vitamin D deficiency, or kidney disease.
- Hypercalcemia:
- High calcium levels in blood caused by elevated PTH hormone, which removes calcium from bones and puts it into the blood, or cancer as a cause of bone destruction.
- Hypophosphatemia:
- Low phosphorus; caused by decreased intestinal absorption or increased excretion by kidneys.
- Hyperphosphatemia:
- High phosphorus; caused primarily by kidney failure.
- Hypomagnesemia:
- Low magnesium levels due to sepsis, burns, laxative abuse, diarrhea, increased renal excretion, and wounds.
- Hypermagnesemia:
- High magnesium levels due to kidney dysfunction.
Complications of Electrolyte Imbalances
- Hypovolemic Hyponatremia can cause confusion, behavioral changes (common in elderly), and increased risk of falls.
- Hypervolemic Hyponatremia can result in fluid shifting from the extracellular fluid (ECF) to the intracellular fluid (ICF) causing cell swelling, potentially brain swelling leading to seizures or coma.
- Hypernatremia leads to cell dehydration and shrinkage, impacting neuron function and cell responsiveness.
- Hypokalemia can cause cardiac dysrhythmias, cardiac issues, and muscle weakness/cramps.
- Hyperkalemia results in bradycardia, dysrhythmias, and potentially cardiac arrest.
- Hypocalcemia leads to bone pain and fragility.
- Hypercalcemia can cause kidney failure, kidney stones, nervous system issues, and bone problems.
- Hypophosphatemia and Hyperphosphatemia lead to bone-related issues.
- Hypomagnesemia can cause long-term cardiovascular disease, diabetes, osteoporosis.
- Hypermagnesemia results in cardiovascular disease, low blood pressure, and arrhythmias, confusion, and lethargy.
Signs and Symptoms of Electrolyte Imbalances
- Specific symptoms for each imbalance are provided in the notes, including those related to the amount of fluid in the body.
