90-95% of cases are type 2
Can be prevented to delayed
Usually type 2 pts are overweight and older
Lab tests used in the dx of diabetes
Fasting blood sugar
Casual (random) blood sugar
Glycated hemoglobin (HbgA1C)
Urine examinations to look for glucose, protein, ketones
A fasting blood sugar is collected when? and what is the diagnostic criteria for type 1 diabetes?
Usually 8 hours (no calories) and
greater than or equal to 126 mg/ mL
A casual or random blood sugar is collected because of what indication and what is the diagnostic criteria for type 1 diabetes?
It can be collected anytime and it requires symptoms
greater than or equal to 200 mg/ mL
The pt will be showing classic symptoms of hyperglycemia or hyperglycemia
Glycated Hemoglobin (HgbA1C) lab value diagnostic criteria for type 1 diabetes?
greater than or equal to 6.5%
Average blood sugar over than last 3-4 months
HgbA1C value without diabetes: 4 - 5.6%
HgbA1C that indicates a high chance of diabetes: 5.7 - 6.4%
[we like to keep the pt below 7% (150)]
Deficits in insulin can cause:
non traumatic amputation
cause CVD (which can kill you)
leading cause of blindness
can hospitalize you
How can you manage diabetes?
Exercise
Nutrition
Pharmacologic tx
Education
Monitoring - SMBG (self monitoring blood glucose) - capillary blood
The normal range of HgbA1C is?
4.0% - 5.5%
A HgbA1C elevated lab value reflects what?
Hyperglycemia in people with diabetes
What is the cause of type 2 diabetes?
