Hypoglycemia

Symptoms

If blood sugar levels become too low, signs and symptoms can include:

  • An irregular or fast heartbeat
  • Fatigue
  • Pale skin
  • Shakiness
  • Anxiety
  • Sweating
  • Hunger
  • Irritability
  • Tingling or numbness of the lips, tongue or cheek

As hypoglycemia worsens, signs and symptoms can include:

  • Confusion, abnormal behavior or both, such as the inability to complete routine tasks
  • Visual disturbances, such as blurred vision
  • Seizures
  • Loss of consciousness

When to see a doctor

Seek a doctor's help immediately if:

  • You have what might be hypoglycemia symptoms and you don't have diabetes
  • You have diabetes and hypoglycemia isn't responding to treatment, such as drinking juice or regular soft drinks, eating candy, or taking glucose tablets

Seek emergency help for someone with diabetes or a history of hypoglycemia who has symptoms of severe hypoglycemia or loses consciousness.
