MDCast: DKA in Disguise | What Pregnancy Symptoms Hide
Episode 286
Thursday, 8 January, 2026
In this episode of the FlightBridgeED OB Critical Care Transport series, Dr. Mike Lauria is joined by maternal-fetal medicine specialist Dr. Liz Gartner to tackle one of the most commonly missed and dangerous metabolic emergencies in pregnancy: diabetic ketoacidosis (DKA). While DKA is familiar to most clinicians, pregnancy dramatically alters its presentation—often masking it behind symptoms that look indistinguishable from “normal” pregnancy complaints like nausea, vomiting, abdominal pain, fatigue, and polyuria.The conversation breaks down the unique physiology of pregnancy that predisposes patients to DKA at much lower glucose levels than expected. Progressive insulin resistance, hemodilution, increased renal glucose losses, accelerated starvation, and baseline respiratory alkalosis combine to create a perfect storm where euglycemic or near-euglycemic DKA can develop. The result is a high-risk condition that is easy to dismiss unless providers intentionally look for it—especially in patients with type 1 diabetes, type 2 diabetes, or gestational diabetes.From a transport and critical care perspective, the episode emphasizes early recognition, appropriate lab interpretation, and aggressive maternal resuscitation as the cornerstone of treatment. The hosts clarify that management principles remain largely unchanged from non-pregnant patients—fluids first, electrolytes (especially potassium), then insulin—while highlighting pregnancy-specific lab pitfalls and why delivery is not the treatment for DKA. Ultimately, stabilizing the mother is the most effective way to protect the fetus.Key takeawaysDKA can look like normal pregnancy: Nausea, vomiting, fatigue, abdominal pain, and polyuria should not be dismissed in pregnant patients with diabetes.Don’t be reassured by a glucose of ~200: Up to 30% of DKA cases in pregnancy are euglycemic.Pregnancy changes the labs: Baseline bicarbonate is lower, and a pH around 7.30 may represent severe acidosis.Beta-hydroxybutyrate is the gold standard for diagnosing ketosis; urine ketones and anion gap alone can miss cases.Fluids and electrolytes come first: Aggressive volume resuscitation and potassium correction are critical before insulin.Resuscitate mom to save baby: Delivery is not indicated for DKA alone and may worsen outcomes.High fetal risk: While maternal mortality is low, fetal mortality remains significant—making early recognition essential.
