Often precipitated by another problem--> infection, MI, hypovolemia, poor pos, pancreatitis, meds (steroids), PE, other physiological stress; and/or not taking insulin
May also be initial presentation w/type 1 DM
Euglycemic DKA: can occur w/sugar < 200, but with all of the other DKA manifestations; Overall, rare; Can occur in Type 1s or Type 2s on SGLT2 inhibitors
Risk Factors
Known DM
Known poor control
Acute other illness that is a precipitant
Symptoms
Polyuria, polydypsia
Fatigued/feeling poorly to confusion to unarousable
Physical Exam Findings
Often ill appearing
Tachycardia, and sometimes low BP
Tachypnea w/deep breaths (Kussmaul breathing)--> respiratory compensation for metabolic acidosis
Sometimes focal findings if there's an underlying physiologic driver (e.g. infection/sepsis, pancreatitis)
