Hypoglycemia Symptoms

How to tell your blood glucose level is low

When glucose drops below normal levels, you may develop symptoms of low blood sugar (low blood glucose). Your body needs the right amount of glucose to operate efficiently, and low blood glucose can lead to a variety of symptoms affecting different parts of your body (e.g., eyes and heart).

Possible symptoms of hypoglycemia include:

  • Anxiety
  • Blurred vision
  • Confusion
  • Dizziness
  • Fatigue, sleepiness, weakness
  • Heart palpitations
  • Hunger
  • Nervousness
  • Nightmares
  • Shakiness
  • Sweating
  • Tremors

We should point out that some people have no hypoglycemia symptoms at all.

Hypoglycemia should trigger the release of epinephrine (adrenaline), a stress hormone produced by your adrenal glands. Epinephrine causes the symptoms listed above in reaction to low blood sugar, alerting you that something is wrong.

If hypoglycemia symptoms are ignored and not treated, hypoglycemia can occur again and again until, the body cannot identify when a low blood glucose occurs. This is called hypoglycemia unawareness.

Severe low blood sugar can lead to loss of consciousness, so it is important to treat promptly.

Sometimes symptoms associated with hypoglycemia are the same or similar to those caused by other conditions. That is one reason why it is important to talk to you doctor or endocrinologist for a proper diagnosis.
