Somogyi phenomenon presents with which symptom pattern?

• A. 6 AM blood sugar 58 mg/dL and nausea
• B. Drowsiness and disorientation after eating
• C. Abdominal pain and elevated blood pressure
• D. Headache on awakening and enuresis

Answer: (D)

Somogyi phenomenon occurs when overnight insulin causes hypoglycemia, and the body responds with counterregulatory hormones (like epinephrine, cortisol, and growth hormone) that drive glucose production up, producing morning hyperglycemia. The classic clinical clue is waking with a headache due to this rebound high glucose, and enuresis can occur from the overnight glycemic swings and resulting polyuria. So the pattern of headache on awakening with enuresis fits this rebound hyperglycemia after nocturnal hypoglycemia. Other patterns describe true morning hypoglycemia or symptoms not tied to this nocturnal rebound mechanism.
