Here's your reel-ready DKA breakdown β€” short, crisp, and easy to follow:

πŸ”΄ DKA β€” Diabetic Ketoacidosis

What is it?

A life-threatening complication of diabetes (mainly Type 1) where the body has no insulin β†’ can't use glucose for fuel β†’ burns fat instead β†’ produces ketones β†’ blood turns acidic.

The Deadly Trio

High glucose + Ketones + Acidosis

Why does it happen?

  • No insulin (missed doses, new diagnosis)
  • Infection, surgery, stress (triggers even with insulin)
  • SGLT2 inhibitors (rare euglycemic DKA)

Pathophysiology (in 4 steps)

  1. No insulin β†’ cells starve despite high blood glucose
  2. Fat breaks down β†’ free fatty acids flood the liver
  3. Liver converts them to ketones (Ξ²-hydroxybutyrate, acetoacetate)
  4. Ketones drop blood pH β†’ metabolic acidosis

Classic Symptoms

SymptomWhy
Polyuria / PolydipsiaOsmotic diuresis from hyperglycemia
Nausea, vomitingKetosis
Kussmaul breathingBody blowing off COβ‚‚ to compensate for acidosis
Fruity breathAcetone (a ketone) being exhaled
Confusion / lethargyHyperosmolarity + acidosis

Diagnosis (the numbers to know)

  • Blood glucose > 250 mg/dL
  • pH < 7.3
  • Bicarbonate < 18 mEq/L
  • Positive ketones (serum Ξ²-hydroxybutyrate elevated)
  • Anion gap metabolic acidosis
⚠️ Urine dipstick can miss Ξ²-hydroxybutyrate β€” measure serum ketones directly.

Treatment (3 pillars)

  1. IV fluids β€” correct profound dehydration
  2. Insulin drip β€” shut off ketone production, drive glucose into cells
  3. Potassium replacement β€” serum K⁺ looks normal/high but total body stores are depleted; insulin will crash it further
Bicarbonate only if pH < 7.0 β€” routine use risks cerebral edema.

Complications to watch

  • Cerebral edema (especially in kids β€” most feared)
  • Hypokalemia (as insulin is given)
  • Hypoglycemia (if glucose correction is too fast)

Key Takeaway for the Reel

No insulin β†’ body burns fat β†’ acid builds up β†’ medical emergency. Fix it with fluids, insulin, and potassium.

DKA β€” 60-Second Reel Script

What is DKA? No insulin β†’ body burns fat β†’ blood turns acidic. Medical emergency.
The Deadly Trio: πŸ”Ί High glucose Β· πŸ”Ί Ketones Β· πŸ”» pH
Spot it:
  • Fruity breath
  • Deep, rapid breathing (Kussmaul)
  • Nausea, vomiting
  • Confusion
Diagnose it: Glucose > 250 Β· pH < 7.3 Β· Bicarb < 18 Β· Anion gap ↑
Treat it β€” 3 things:
  1. πŸ’§ IV Fluids
  2. πŸ’‰ Insulin drip
  3. πŸ§ͺ Replace Potassium
Remember: Serum K⁺ looks normal β€” but total body stores are low. Give insulin β†’ K⁺ crashes. Always replace it.
Most feared complication: Cerebral edema. Avoid routine bicarb β€” it makes it worse.
No insulin. Fat burns. Acid builds. Act fast.
