Hypoglycemia vs Hyperglycemia

Hypoglycemia vs Hyperglycemia


Americans who have been diagnosed with diabetes has grown a great deal over the last six decades and remains the 7th leading cause of death in the United States. Those diagnosed with diabetes are at risk for a number of conditions, including both Hyperglycemia or Hypoglycemia.

Hyperglycemia and hypoglycemia are both dangerous conditions involving blood sugar. While these conditions can happen to anyone, it’s a major concern for those diagnosed with diabetes. Below is information about hypoglycemia and hyperglycemia, and the symptoms you need to look out for.


Hypoglycemia occurs when there is not enough glucose in your blood and usually comes on suddenly. It can happen for several reasons, but waiting too long to eat and strenuous exercise are common culprits.

Symptoms of Hypoglycemia

Shakiness, dizziness, weakness
Rapid pulse
Irritability (“hangry”)
Difficulty concentrating


Unlike hypoglycemia, hyperglycemia (too much sugar in your blood) usually occurs slowly, over the course of several hours or days.

Symptoms of hyperglycemia

Increased fatigue
Difficulty concentrating
Blurred vision
Intense thirst
Increased urination
Involuntary weight loss
Excessive hunger

To prevent these conditions, it’s important to keep an eye on your blood sugar levels. Schedule a doctor’s appointment if your blood sugar remains above 240 mg/dl consistently, or if you have severe symptoms of hypoglycemia.
