Diabetes Flashcards
what is diabetes?
an elevation of blood glucose above a diagnostic threshold
what happens to average fasting plasma glucose as the age of patients increases?
it increases
what are the thresholds for diagnosis of diabetes based on?
the risk of developing diabetic retinopathy
what fasting glucose suggests normal glucose tolerance?
6.0mmol/L and below
what 2 hour glucose suggests normal glucose tolerance?
7.7mmol/L and below
what HbA1c suggests normal glucose tolerance?
41 mmol/mol and below
what fasting glucose indicates impaired glucose tolerance?
6.1 - 6.9 mmol/L
what 2 hour glucose indicates impaired glucose tolerance?
7.8 - 11.0 mmol/L
what HbA1c indicates impaired glucose tolerance?
42-47 mmol/L
what is another name for impaired glucose tolerance?
pre diabetes
what fasting glucose is diagnostic of diabetes?
7.0mmol/L and above
what 2 hour glucose is diagnostic of diabetes?
11.1mmol/L and above
what random glucose is diagnostic of diabetes?
11.1mmol/L and above
what HbA1c is diagnostic of glucose?
48 mmol/mol and above
aka 5.8% and above
what determines the thresholds for diagnosing gestational diabetes?
not based on the risk of retinopathy
determined by the risk to the foetus
what is gestational diabetes?
diabetes that comes on during pregnancy
which has higher thresholds - regular diabetes or gestational diabetes?
normal diabetes
values for diagnosis of gestational diabetes are much lower
what happens when plasma glucose is low?
alpha cells release glucagon to raise it again
what happens when plasma glucose is high?
beta cells release insulin to lower it
what can be measured to measure endogenous insulin secretion?
C-peptide
