- age 40+
- first degree relative
- high risk ethnicity
- hx of pre-DM or GDM
- hx of macrosomic infant
- end organ damage (retinopathy, neuropathy, nephropathy, CV)
- vascular risk factors
- associated diseases (separate card)
- meds (separate card)

Risk factors for DM type 2
What are some vascular risk factors?
HDL <1 in males, <1.3 in females TG >1.7 HTN Obesity (esp abdo) Smoking
What are early signs of DM?
- recurrent infections (yeast, UTI)
- fatigue
- blurred vision
4 P’s:
- paresthesia
- polyuria
- polydipsia
- polyphagia
How often should screening occur for:
-risk factors?
How often should DM screening occur
- if no risk factors?
- if presence of risk factors?
Screen risk factors ANNUALLY
If no risk factors:
age 40+: q3 years
If risk factors: q6-12 months
What is the cut-off threshold for diagnosis of diabetes:
FPG:
A1C:
75 g OTT:
Random PG:
FPG: 7.0 and above
A1C: 6.5 and above
2 hr PG 75 OGTT: 11.1 and above
Random PG: 11.1
DM screening using FPG and A1C:
- if one test is in diabetic range, what is the next step?
- if both tests are in diabetic range, what is the next step?
If no hyperglycemia symptoms:
• if ONE test is in diabetes range, repeat same test on a different day for confirmatory testing
• If BOTH in diabetes range, diagnosis confirmed
*if symptomatic then do not need to confirm before initiating treatment
What is the range of FPG for impaired fasting glucose?
6.1-6.9
What is the range of A1C for prediabetes?
6.0-6.4
what tests to use for screening in elderly?
when to stop screening?
both A1C and fasting glucose
A1C progressively elevated in elderly
unlikely beneficial after age 80
symptoms of diabetes in older adults?
Dehydration (altered thirst perception, delayed fluid intake)
Incontinence
Older adults tend to have vague symptoms (of course)
Dry eyes, dry mouth, confusion, diabetic complications
Weight loss / HONK
Geriatric syndromes: pain, incontinence, cognitive impairment, depression, falls, polypharmacy
