Glucose level of diabetes patients


Normal levels for non-diabetics 70 to 99 mg/dl
ADA proposal for diabetics 80 to 130 mg/dl

Sugar level after a meal

Normal levels for non-diabetics Below 140 mg/dl
ADA proposal for diabetics Below 180 mg/dl

HbA1c (Glycated Hemoglobin)

Normal levels for non-diabetics Below 5.7%
ADA proposal for diabetics Below 7.0%

What level of blood sugar is dangerous?

Yes, high glucose levels may be dangerous. Even though high glucose levels produce signs of too much thirst, hunger, urination, and weight loss, with time these high levels may lead to:

  •         hazy vision,
  •         paresthesias of lower extremities (“pins and needles” feelings),
  •         eye and kidney damage,
  •         greater risk of stroke and heart attack,
  •          greater risk for infections.

Very high glucose levels (1000 mg/dL or above) may lead to diabetic ketoacidosis. And, this may cause unconsciousness and is dangerous for life. The treatment for too much high blood glucose includes insulin and IV fluids.

Are low glucose levels dangerous?

Yes, low blood glucose signs may lead to problems like

  •         hunger,
  •         anxiety,
  •         too much sweat,
  •         drowsiness, and even confusion;

When left unmanaged, low blood glucose (or, hypoglycemia) might cause:

  •         convulsions,
  •         coma,
  •         unconsciousness,
  •         death.

Low glucose levels start at 70 mg/dL or below. Diabetic patients who consume an excessive medicine (insulin) or consume their standard quantity, yet consume less or exercise more might develop hypoglycemia. Even though it is rarer, hypoglycemia may occur in some non-diabetics when they:

  •         consume somebody’s medicine
  •         consume too much alcohol,
  •         experience hepatitis or insulinoma (which is a rare tumor of the pancreas).
