Mild Type 2 Diabetes ?
Aims of Mx of DM
Improve quality of life
Reduce acute symptoms
Achieve euglycemia safely
Avoid Acute &
Chronic
Complications
ADA 2015
A patient-centered communication style that incorporates
patient preferences, assesses literacy and numeracy, and
addresses cultural barriers to care should be used. B
Treatment decisions should be timely and founded on
evidence-based guidelines that are tailored to individual
patient preferences, prognoses, and co-morbidities. B
Criteria for the Diagnosis of Diabetes
A1C ≥6.5% Adults
OR
Fasting plasma glucose (FPG)
≥126 mg/dL (7.0 mmol/L)
OR
2-h plasma glucose ≥200 mg/dL
(11.1 mmol/L) during an OGTT
OR
A random plasma glucose ≥200 mg/dL (11.1
mmol/L)
ADA. I. Classification and Diagnosis. Diabetes Care 2014;37(suppl 1):S15; Table 2
Testing for Diabetes in Asymptomatic Adult Patients
• Adults of any age who are overweight / obese (BMI ≥25
kg/m2 or ≥23 kg/m2 in Asian Americans) and who have
one or more additional risk factors for diabetes.
• For all patients, particularly those who are overweight
or obese, testing should begin at age 45 years. B
• To test for pre-diabetes, the A1C, FPG, or 2-h 75-g
OGTT are appropriate B
• In those with pre-diabetes, identify and, if appropriate,
treat other CVD risk factors E
ADA. II. Testing for Diabetes in Asymptomatic Patients. Diabetes Care 2015
Testing for Diabetes in Asymptomatic Adult Individuals
• Physical inactivity
• First-degree relative with
diabetes
• High-risk race/ethnicity (e.g.,
African American, Latino, Native
American, Asian American,
Pacific Islander)
• Women who delivered a baby
weighing >9 lb or were diagnosed
with GDM
• Hypertension (≥140/90 mmHg or
on therapy for hypertension)
• HDL cholesterol level
<35 mg/dL (0.90 mmol/L) and/or a
triglyceride level >250 mg/dL (2.82
mmol/L)
• Women with polycystic ovarian
syndrome (PCOS)
• A1C ≥5.7%, IGT, or IFG on
previous testing
• Other clinical conditions associated
with insulin resistance (e.g., severe
obesity, acanthosis nigricans)
• History of CVD
*At-risk BMI may be lower in some ethnic groups.
1. Testing should be considered in all adults who are overweight
(BMI ≥25 kg/m2 or ≥23 kg/m2 in Asian Americans) and have additional risk
factors:
ADA. Testing for Diabetes in Asymptomatic Patients. Diabetes Care 2015
2. If tests are normal, repeat testing at least at 3-year
intervals is reasonable C
Consider more frequent testing depending on initial
results and risk status (e.g., those with prediabetes should
be tested yearly)
ADA. Testing for Diabetes in Asymptomatic Patients. Diabetes Care 2015
Testing for Diabetes in Asymptomatic Adult Individuals
Recommendations:Detection and Diagnosis of GDM (1)
• Screen for undiagnosed type 2 DM at the first prenatal visit in those with risk factors, using standard diagnostic criteria
B
• Screen for GDM at 24–28 weeks of gestation in pregnant women not previously known to have DM A
• Screen women with GDM for persistent DM at 6–12 weeks postpartum, using OGTT, nonpregnancy diagnostic criteria
E
• Women with a +ve history of GDM should have lifelong screening for the development of DM or pre-DM at least every 3 years B
• Women with a history of GDM found to have pre-DM should receive TLC or Metformin to prevent DM
A
Detection and Diagnosis of GDM. Diabetes Care 2015
One-step strategy (IADPSG Consensus)
• Perform a 75-g OGTT, with plasma glucose measurement when patient is fasting and at 1 and 2 h, at 24–28 weeks of gestation in women not previously diagnosed with overt diabetes.
• The OGTT should be performed in the morning after an overnight fast of at least 8 h
The diagnosis of GDM is made when any of the following plasma glucose values are met or exceeded:
• Fasting: ≥ 92 mg/dL (5.1 mmol/L)
• 1 h: ≥ 180 mg/dL (10.0 mmol/L)
• 2 h: ≥ 153 mg/dL (8.5 mmol/L)
Detection and Diagnosis of GDM. Diabetes Care 2015
Table 2.5—Screening for and diagnosis of GDM
Table 2.5—Screening for and diagnosis of GDM
Two-step strategy (2013 -NIH Consensus)
• Step 1: Perform a 50-g GLT (non-fasting), with plasma glucose
measurement at 1 h, at 24–28 weeks of gestation in women not
previously diagnosed with overt diabetes.
• If the plasma glucose level measured 1 h after the load is ≥140 mg/dL*
(7.8 mmol/L), proceed to a 100-g OGTT
NDDG, National Diabetes Data Group.
*The ACOG recommends a lower threshold of 135 mg/dL (7.5 mmol/L) in high-risk ethnic
populations with higher prevalence of GDM;
Some experts also recommend 130 mg/dL (7.2 mmol/L).
Detection and Diagnosis of GDM. Diabetes Care 2015
Two-step strategy…
• Step 2: The 100-g OGTT should be performed when the patient is fasting.
• The diagnosis of GDM is made if at least two of the following four plasma glucose levels
• (measured fasting and 1 h, 2 h, 3 h after the OGTT) are met or exceeded:
• Carpenter/Coustan or NDDG
Fasting 95 mg/dL (5.3 mmol/L) 105 mg/dL (5.8 mmol/L)
1 h 180 mg/dL (10.0 mmol/L) 190 mg/dL (10.6 mmol/L)
2 h 155 mg/dL (8.6 mmol/L) 165 mg/dL (9.2 mmol/L)
3 h 140 mg/dL (7.8 mmol/L) 145 mg/dL (8.0 mmol/L)
Table 2.5—Screening for and diagnosis of GDM
Detection and Diagnosis of GDM. Diabetes Care 2015
PREVENTION / DELAY OFTYPE 2 DIABETES
FPG 100–125 mg/dL (5.6–6.9 mmol/L): IFG
OR
2-h plasma glucose in the 75-g OGTT
140–199 mg/dL (7.8–11.0 mmol/L): IGT
OR
A1C 5.7–6.4%
For all three tests, risk is continuous, extending below the lower
limit of the range and becoming disproportionately greater at
higher ends of the range.
Pre-Diabetes
ADA. I. Classification and Diagnosis. Diabetes Care 2015
Prevention /Delay of Type 2 DM
Patients with IGT (A), IFG (E), or
an A1C of 5.7–6.4% (E)
Weight loss of 7% of body weight
Physical activity ; at least 150 min/ week
Follow-up counseling for success. (B)
Diabetes prevention is cost-effective (B)
ADA 2015
All patients should limit the amount of time
sitting to less than 90 minutes a stretch
(Avoid Sedentary Life )
Prevention /Delay of Type 2 DM
Metformin therapy may be considered in:
IGT (A), IFG(E), or an A1Cof 5.7–6.4% (E)
Especially for those with: (A)
-BMI >35 kg/m2
-Age <60 years,
-Prior GDM.
At least annual monitoring for the development
of DM in those with pre-diabetes is suggested. (E)
ADA 2015Micronutrients and Supplements
Evidence does not support recommending omega-3
supplements for people with diabetes for the prevention or
treatment of cardiovascular events.
There is no clear evidence of benefit from vitamin or
mineral supplementation in people with diabetes who do not
have underlying deficiencies. C
Routine supplementation with antioxidants, such as
vitamins E and C and carotene, is not advised due to
insufficient evidence of efficacy and concerns related to long-
term safety. C
.
ADA 2015Micronutrients and herbal supplements
There is insufficient evidence to support the routine use of
micronutrients such as chromium, magnesium, and vitamin D
to improve glycemic control in people with diabetes C
There is insufficient evidence to support the use of
cinnamon or other herbs/supplements for the treatment of
diabetes. E
Routine screening for CAD is
Not recommended
In asymptomatic patients
(It does not improve outcomes as long as CVD risk factors are treated)
(A)
Coronary Heart Disease Screening
ADA. VI. Prevention, Management of Complications. Diabetes Care 2014;37(suppl 1):S42
• To reduce risk of cardiovascular events in
patients with known CVD, use
– ACE inhibitor* (C)
– Aspirin* (A)
– Statin therapy* (A)
• In patients with a prior MI
– Beta-blockers should be continued for at least 2
years after the event (B)
Coronary Heart Disease Treatment
*If not contraindicated.
ADA. VI. Prevention, Management of Complications. Diabetes Care 2014;37(suppl 1):S42
GLYCEMIC CONTROL
1. Assessment of Glycemic control
Two primary techniques:
A : Patient self-monitoring of blood glucose
(SMBG) or Interstitial Glucose (CGM)
B : HbA1C
2. Glycemic goals in adults
ADA. V. Diabetes Care. Diabetes Care 2014;37(suppl 1):S21–S22
ADA-2015
Glycemic ControlSMBG
Tight Glycemic control : SMBG is an integral part of
the management strategy. (A)
Do SMBG ≥ 3 times a day for patients using Insulin
pump or multiple insulin injections. (B)
Patients using less frequent insulin injections or oral agents or MNT alone, SMBG is useful (E)
PP SMBG may be appropriate. (E)
Especially when getting closer to target; Lower A1c
Glycemic ControlRecommendations

Evidence –Based / Individualized Rx
HYPERTENSIONBP CONTROL
Goals
*People with diabetes and hypertension should be
treated to a (SBP) goal of <140 mmHg. A
Lower systolic targets, such as <130 mmHg, may be appropriate for
certain individuals, such as younger patients, if they can be achieved
without undue treatment burden. C
*Individuals with diabetes should be treated to a
(DBP) <90 mmHg. A
Lower (DBP) targets, such as <80 mmHg, may be appropriate for certain
individuals, such as younger patients, if they can be achieved without undue treatment burden. B
• Patients with confirmed office-based BP
>140/90 mm Hg
=
Prompt initiation of pharmacological therapy to
achieve blood pressure goals. A
HYPERTENSIONBP CONTROL
• Lifestyle therapy for elevated BP B
– Weight loss if overweight/ obese
– DASH (Dietary Approaches to Stop Hypertension) -
style dietary pattern including reducing sodium,
increasing potassium intake
– Moderation of alcohol intake
– Increased physical activity
HYPERTENSIONBP CONTROL
ADA. VI. Prevention, Management of Complications. Diabetes Care 2014;37(suppl 1):S36

ACE (-) or ARBs (Don’t combine)
or Diuretics
Monitor serum creatinine / (e GFR)
and serum potassium levels.
(E)
Hypertension MxRecommendations
Multiple Drug Therapy (≥ 2 agents) is

DYSLIPIDEMIA
Intensity Vs Targets
DIABETES CARE, VOLUME 35, SUPPLEMENT 1, JANUARY 2012
Screening
• At the time of first diagnosis
• Initial medical evaluation
• and/or at age 40 years and
Re-assessments may be repeated
periodically every 1-2 years (E)
Recommendations:Dyslipidemia/Lipid Management
DIABETES CARE, VOLUME 35, SUPPLEMENT 1, JANUARY 2012.
LipidsRx Recommendations and Goals
Lifestyle modification (TLC) has been
shown to Improve the lipid profile in
patients with diabetes. (A)
This include:
- Reduction of saturated fat, trans fat, and cholesterol intake
-Increase of n-3 fatty acids, viscous fiber and plant stanols / sterols
-Weight loss (if indicated); and increased physical activity
Lipids
ADA 2014… was
To get specified LDL target
Statin therapy should be added, regardless of
baseline lipid levels, for DM patients:
- With overt CVD.
-Without CVD who is > 40 years old and have ≥ 1 other
CVD risk factors. (A)
A reduction in LDL cholesterol of 30–40% from
baseline is an alternative therapeutic goal. (A)
Statins use is based on desired
LDL-C Intensity lowering
rather than LDL target number
Adjustment of intensity of statin therapy
may be needed based on individual patient response to
medication
(e.g., side effects, tolerability, LDL cholesterol levels). E
