Q

who should you consider screening for diabetes

A

all adults who are OVERWEIGHT (BMI >25) and have one or more additional risk factors:

  • physically inactive
  • first-degree relative with T2DM
  • member of high risk community (African American, Latinx, Native American, Asian American, Pacific Islander)
  • given birth to a baby >9lbs (4kg) or h/o GDM
  • HTN
  • low HDL<35 and/or elevated triglycerides >250
  • PCOS
  • A1c >5.7%, impaired glucose tolerance, or impaired fasting glucose on prior testing
  • other signs associated with insulin resistance such as obesity, acanthosis nigricans
  • CVD

Q

(3) different lab tests that can be used to diagnose diabetes

A
  • plasma glucose (fasting or random - cheapest test)
  • OGTT (most expensive, least convenient)
  • A1c (looks at average glycemic control over 3 months, convenient, cheap)

low
70
weight impact: SGLT2 inhibitors (empagliflozin, canagliflozin, dapagliflozin)
loss
71
adverse effects: SGLT2 inhibitors (empagliflozin, canagliflozin, dapagliflozin)
GU infections (candida, UTI), dehydration this is because you are peeing out sugar the sugar is leaving the body attached to water, so it can cause dehydration --> be wary with older adults who don't drink water
72
cost consideration: SGLT2 inhibitors (empagliflozin, canagliflozin, dapagliflozin)
expensive
73
compelling indication: SGLT2 inhibitors (empagliflozin, canagliflozin, dapagliflozin)

79
of all medication classes in diabetes, which will always give you the best A1c reduction?
insulin and you can titrate up as much as you need
80
hypoglycemia risk: insulin
high
81
weight impact: insulin
gain
82
adverse effect: insulin
hypoglycemia
83
cost consideration: insulin
expensive (NPH and regular insulin are less expensive, but not used as commonly anymore)
84
compelling indication: insulin
when 2 or more drugs (including insulin releasers) are no longer adequate to maintain glycemic control, this is a marker of beta cell failure and must supplement with exogenous insulin
85
when to consider starting your T2DM patient on insulin?
once they are no longer meeting therapeutic goals on 2 or more antidiabetic medications (including an insulin releaser), this is an indication of possible beta cell failure and requires supplementation with exogenous insulin
86
who needs insulin in T1DM?
EVERYONE! they would die without exogenous insulin
87
general rule of insulins: % bolus vs. % basal
50% basal | 50% bolus
88
with whom should you consider starting insulin right off the bat with new T2DM diagnosis?
if A1c >9% and/or with symptoms (polys, visual changes, etc.) short course of insulin for 2-3 weeks (also concurrent metformin) can help achieve normoglycemia, and then see if they can come off
