Lactic acidosis

By Type

  • Type A (tissue hypoperfusion)
  • Type B (decreased utilization)
  • Type D
    • episodes of encephalopathy and metabolic acidosis typically following high carbohydrate meals in patients with short bowel syndrome
    • metabolic acidosis and high serum anion gap, normal lactate level, short bowel syn or other forms of malabsorption, and characteristic neurologic findings
      • Type D lactate is not detected with standard lactate levels
