Recognizing Low and High Blood Glucose Levels

Last updated 4 years ago

Part of managing diabetes is keeping blood glucose levels in a target range. Having blood glucose that is too high or too low can cause dangerous effects. Watch this video to learn about blood sugar levels that fall outside of the target range.

Hyperglycemia is another term for high blood glucose. In the short term, hyperglycemia can cause nausea, excessive thirst, and dehydration. Long-term hyperglycemia can cause damage to kidneys, eyes, blood vessels, and nerves. Hypoglycemia is low blood glucose. When it occurs, it causes confusion, dizziness, sweating, and, in some cases, unconsciousness.

Both hyperglycemia and hypoglycemia can be medical emergencies, so talk to your endocrinologist about treating your highs and lows and when to go to Northside Hospital in St. Petersburg for emergency services. For a referral to a physician who can help with your diabetes care or for more information about our hospital, call (888) 598-9586.
