Study Notes

Fluids and Electrolyte Imbalances

  • Electrolyte imbalances occur when there's too much or too little of certain minerals in the body.
  • Electrolytes are electrically charged minerals dissolved in body fluids.
  • They are crucial for nerve and muscle function, fluid balance, and maintaining optimal bodily conditions.
  • Common electrolytes include sodium, potassium, chloride, calcium, magnesium, phosphate, and bicarbonate.

Electrolyte Functions

  • Sodium: Controls fluid levels, aids nerve and muscle function.
  • Potassium: Supports heart, nerve, and muscle function, moving nutrients into cells and waste products out.
  • Calcium: Helps blood vessels' contraction and expansion, stabilizing blood pressure and secreting critical hormones and enzymes.
  • Chloride: Maintains healthy blood levels, blood pressure, and bodily fluids. Supports nerve and muscle function, bone and tooth growth.
  • Magnesium: Aids nerve and muscle function, and promotes bone and teeth growth.
  • Bicarbonate: Balances acids and bases in blood (pH balance), moving carbon dioxide through the bloodstream.
  • Phosphate: Supports the skeletal system, as well as nerve and muscle function, important for cell growth and energy production.

Causes of Electrolyte Imbalances

  • Various conditions/medications that disrupt the body's natural fluid balance.
  • Kidney disease
  • Congestive heart failure
  • Hepatic cirrhosis
  • Syndrome of inappropriate ADH secretion (SIADH)
  • Adrenal insufficiency
  • Hypothyroidism
  • Excessive fluid intake (primary polydipsia)
  • Low dietary sodium intake
  • Hyperglycemia
  • Dyslipidemia

Symptoms of Electrolyte Imbalances

  • Confusion and irritability
  • Diarrhea or constipation
  • Fatigue
  • Headaches
  • Irregular or fast heart rate (arrhythmia)
  • Muscle cramps, spasms, or weakness
  • Nausea and vomiting
  • Numbness or tingling in limbs, fingers, and toes

Types of Electrolyte Imbalances

  • Hypercalcemia: Too much calcium in the blood (kidney disease, hyperparathyroidism, etc.)
  • Hypocalcemia: Too little calcium in the blood (kidney failure, hypoparathyroidism, etc.)
  • Hyperchloremia: Too much chloride in the blood (severe dehydration, metabolic acidosis).
  • Hypochloremia: Too little chloride in the blood (metabolic alkalosis, diuretics).
  • Hypermagnesemia: Too much magnesium in the blood (renal failure, excessive magnesium intake)

Types of Electrolyte Imbalances

  • Hypomagnesemia: Too little magnesium in the blood (alcohol use disorder, malnutrition)

Types of Electrolyte Imbalances

  • Hyperkalemia: Too much potassium in the blood (kidney disease, acidosis)
  • Hypokalemia: Too little potassium in the blood (diuretic use, vomiting, diarrhea)
  • Hyperphosphatemia: Too much phosphate in the blood (kidney disease)
  • Hypophosphatemia: Too little phosphate in the blood (vitamin D deficiency).
  • Hypernatremia: Too much sodium in the blood (severe dehydration)
  • Hyponatremia: Too little sodium in the blood (excessive water intake, syndrome of inappropriate secretion of ADH)

Diagnosing Electrolyte Imbalances

  • Simple blood tests measure electrolyte levels.
  • Electrolyte panel
  • Basic metabolic panel
  • Comprehensive metabolic panel
  • Arterial blood gas (ABG) test measures the pH and electrolyte balance in blood.

Treating Electrolyte Imbalances

  • Intravenous (IV) fluids (rehydration)
  • Electrolyte supplements/medications (calcium gluconate, magnesium sulfate, potassium chloride).
  • Oral medications/supplements
  • Hemodialysis
  • Correcting underlying causes

Risk Factors for Electrolyte Imbalances

  • Infants, young children, and older adults
  • Burns
  • Cancer
  • Cardiovascular diseases, heart failure, or high blood pressure
  • Dehydration
  • Overhydration
  • Eating disorders
  • Kidney disease
  • Liver disease
  • Substance use disorders
  • Medications (antibiotics, chemotherapy drugs, corticosteroids, diuretics, and laxatives)
