Metabolic acidosis is primary reduction in serum bicarbonate, with compensatory tachypnea. High-anion-gap causes: lactic acidosis, ketoacidosis (DKA), renal failure, toxins (salicylate, methanol, ethylene glycol). Normal-anion-gap (hyperchloremic) causes: bicarbonate loss from diarrhea, renal tubular acidosis, and ureteral diversions. Clinical: Kussmaul deep breathing, malaise, confusion, arrhythmias. Treatment: identify and reverse cause; insulin/fluids for DKA; restore perfusion; bicarbonate only in severe acidemia.
Kussmaul breathing; malaise; nausea; confusion; abdominal pain; arrhythmias
Excess acid production, impaired renal acid excretion, or GI/renal bicarbonate loss lowers serum bicarbonate, lowering pH.
Treat underlying cause (DKA/lactic/renal/diarrhea/RTA); restore perfusion; bicarbonate in severe acidemia
Manage diabetes/renal disease; treat diarrhea promptly; monitor critically ill patients.
It is recommended to visit the Internal Medicine department; an appointment can be booked on this platform before the visit.
