DM background Flashcards
Type 1 DM
deficiency of insulin secretion as result to destruction of pancreatic B-cells (autoimmune or virus–> rubella, coxsakievirus B, cytomealvirus, adenovirus, mumps)
Type 2 DM
insulin resistance in muscles and adipose tissue
decline in pancreatic insulin secretion
unrestricted hepatic glucose production
over 90% of all DM cases
S&S of Hyperglycemia
polyuria, polydypsia, polyphagia (loosing weight)
Type 2 DM risk factors
overweight
sedentary lifestyle
fam hx
cardiovascular dz
previously had an impaired glucose tolerance or impaired fasting glucose
HTN
DM screening
BMI greater than 25 Kg/M
if test is negative, test again in 3 yrs
A1C
hemoglobin carries glucose in blood, testing A1C can give you an idea how much glucose the hemoglobin has been picking up in the past 3 months (3 mo=life of RBC)
Normal A1C
less than 5.7%
Pre-Diabetic AIC
between 5.7-6.4%
A1C thats diabetic
greater than 6.5%
Normal fasting plasma glucose
less than 100mg/dL
Pre-Diabetic Fasting plasma glucose
100-125mg/dL
Diabetic Fasting plasma glucose
over 126
Oral glucose tolerance test–> 2 hrs post
used to Dx gestational diabetes
Normal 2 hrs post oral glucose tolerance test
less than 140mg/dL
Pre-Diabetes 2 hrs post oral glucose tolerance test
140-199 mg/dL
Diabetes 2 hrs post oral glucose tolerance test
over 200 mg/dL
Tx goals in Dm
keep A1C below 7%
keep fasting under 100 mg/dL
keep before meal blood glucose level between 7–130mg/dL (which lets you know how well the previous meal was covered)
Tx of Pre-Diabetes
metformin can be used esp if they have a BMI of greater than 35kg/m2, and are under 60
Macrovascular Complications of DM
coronary artery dz
HTN
dyslipidemia
Microvascular Complications of DM
retinopathy
neuropathy
nephropathy
Management of complications of CAD w/DM
men over 50, women over 60 with DM and atleast 1 other risk factor (fam hx of CVD, HTN , Smoking, dyslipedemia, albumenemia)
given 81mg ASA
Management of HTN with Dm
goal 140/80
use ACE-I or ARB (angiotinsen II receptor blocker) (these are first line tx because they protect kidney)
Management of Dyslipidemia with Dm
Goal: LDL under 100
Tx with statin (esp with Hx of MI)
management of retinopathy with DM
manage HTN and glucose
