Electrolyte & Acid–Base Disorders

Electrolyte and acid–base disorders occur when the body’s fluids contain abnormal levels of essential minerals or when blood acidity becomes unbalanced. Electrolytes such as sodium, potassium, calcium, magnesium, chloride, and bicarbonate are vital for nerve activity, muscle contraction, heart rhythm, and cellular function. Disturbances may develop because of dehydration, kidney disease, gastrointestinal losses, hormonal disorders, medications, or severe illness.

Common electrolyte abnormalities include hyponatremia, hypernatremia, hypokalemia, hyperkalemia, hypocalcemia, and hypercalcemia. Symptoms vary according to the affected electrolyte and may include weakness, fatigue, muscle cramps, confusion, nausea, abnormal heart rhythms, or seizures in severe cases.

Acid–base disorders occur when the blood becomes excessively acidic or alkaline. They are broadly classified as metabolic or respiratory acidosis and alkalosis. Conditions such as diabetic ketoacidosis, kidney dysfunction, prolonged vomiting, severe diarrhea, and respiratory diseases can contribute to these abnormalities.

Diagnosis generally involves blood electrolyte measurements, kidney function tests, blood gas analysis, and assessment of the underlying cause. Treatment focuses on correcting the imbalance safely while addressing its source. Depending on severity, management may include fluids, electrolyte replacement, medication adjustment, or emergency medical treatment. Early recognition is important because significant electrolyte and acid–base disturbances can affect vital organs and become life-threatening.
