Overview
Main signs of hypoglycemia are tachycardia and ventricular arrhythmia. Neurological manifestations include altered mental status, hypotonia, focal or general motor deficit and jerks. Neonatal hypoglycemia signs include large for gestational age, hepatomegaly in Beckwith-Wiedemann syndrome and glycogen storage diseases. Ambiguous genitalia, hypertension, hyponatremia, and hyperkalemia are found in congenital adrenal insufficiency.
Physical examination
Appearance
- Macrosomia in infancy may indicate hyperinsulinism.[1]
- In older children and adults, moderately severe hypoglycemia can resemble mania, mental illness, drug intoxication, or drunkenness. In the elderly, hypoglycemia can produce focal stroke-like effects or a hard-to-define malaise. The symptoms of a single person do tend to be similar from episode to episode.
Vitals
Temperature
- Hypothermia may be present in newborns
Pulse
- Rate: Tachycardia may be present.
- Rhythm: The pulse is usually regular.
- Ventricular arrhythmia is fatal if occurred.[2]
Respiration
Skin
Eyes
- Staring, "glassy" look
- Dilated pupils
Extremities
- Cyanosis may be present in newborns
Neurologic
- Mental status may be altered[3]
- Myoclonus
- Hypotonia

Neonatal Physical examination
- Large for gestational age[1]
- Beckwith-Wiedemann syndrome signs: hemihypertrophy, hepatomegaly and macroglossia
- Congenital adrenal insufficiency: ambiguous genitalia, hypertension, hyponatremia, and hyperkalemia
- Congenital hypopituitarism: Midline facial defects and micropenis
- Glycogen storage diseases: hepatomegaly.
