Diagnosis and Classification of Diabetes Mellitus
Criteria for Testing for Diabetes in Asymptomatic, Undiagnosed Individuals
Testing for diabetes should be considered for all individuals age 45 and older and, if normal, should be repeated at 3-year intervals. Testing should be considered at a younger age, or be carried out more frequently, in individuals who:
- Are obese (refer to body mass index [BMI] weight table in the original guideline document)
- Have a first-degree relative with diabetes
- Are members of a high-risk ethnic population (African American, Hispanic, Native American, Asian)
- Have delivered a baby weighing >9 pounds or were diagnosed with gestational diabetes mellitus (GDM)
- Are hypertensive (blood pressure >140/90)
- Have a high density lipoprotein (HDL) cholesterol level <40 mg/dl, and/or a triglyceride level >150 mg/dl
- Had impaired glucose tolerance (IGT) or impaired fasting glucose (IFG) on previous testing
The fasting plasma glucose (FPG) is the preferred diagnostic test due to its ease of administration, convenience, acceptability to patients, and lower cost.
Diagnostic Criteria for Diabetes
An FPG >126 mg/dl (confirmed by testing on two different occasions) is diagnostic for diabetes. The new diagnostic cutpoint (FPG >126 mg/dl) is based on the observation that this degree of hyperglycemia usually reflects a serious metabolic abnormality that has been shown to be associated with serious complications. The revised criteria are for diagnosis and are not treatment criteria or goals. The glycated hemoglobin (HbA1c) is not recommended for diagnosis at this time.

1The FPG is the preferred test
for diagnosis, but any one of the three listed is acceptable. Fasting is defined
as no caloric intake for at least 8 hours.
2Casual is defined as any time of day without
regard to time since last meal. Symptoms are the classic ones of polyuria,
polydipsia, and unexplained weight loss.
3Oral glucose tolerance test should be performed using a glucose load containing the equivalent of 75 g anhydrous glucose
dissolved in water. The OGTT is not recommended for
routine clinical use.
4If casual plasma glucose >160 mg/dl, patient requires diagnostic evaluation for diabetes.
Classification of Diabetes
Type 1
Type 1 diabetes most often results from a cellular mediated autoimmune destruction of the beta cells of the pancreas. Patients with this form of diabetes are dependent upon insulin for survival and are at risk for ketoacidosis. Type 1 commonly occurs in childhood and adolescence but may occur at any age.
Type 2
Individuals with type 2 diabetes have insulin resistance and relative, rather than absolute, insulin deficiency. Primary treatment centers on weight loss, improved nutrition, and increased age-appropriate physical activity. Oral agents may become necessary if the initial treatment is unsuccessful. These patients do not need insulin to survive but may require insulin over time for optimal management, especially if oral agents become ineffective. Type 2 diabetes commonly goes undiagnosed for years because it is often asymptomatic in its early stages. Individuals with undiagnosed type 2 diabetes are at increased risk for developing macro- and microvascular complications.
IFG and IGT
A new stage of impaired glucose homeostasis called impaired fasting glucose (IFG) has been defined as a fasting plasma glucose (FPG) of > 110 mg/dl but
<126 mg/dl. The stage called impaired glucose tolerance (IGT) is defined as an oral glucose tolerance test (OGTT) value of >140 mg/dl but <200 mg/dl. Although not clinical entities in their own right (in the absence of pregnancy), they are risk factors for future diabetes and cardiovascular disease.
GDM
Gestational diabetes mellitus (GDM) is defined as any degree of glucose intolerance with onset or first recognition during pregnancy. The definition applies regardless of whether insulin or only dietary modification is used for treatment. Gestational diabetes mellitus complicates approximately 4% of all pregnancies in the U.S.; however, the prevalence is higher among some minority groups. Six weeks or more after the pregnancy ends, a woman with GDM should be tested to rule out type 1 or 2 diabetes or impaired fasting glucose/impaired glucose tolerance. Women with GDM have a higher risk for type 2 diabetes later in life.

Diabetes Medications
Oral Medications
(see original guideline document for dosages)
Regular testing of blood glucose and HbA1c is recommended to assess medication
effect.
First Generation Sulfonylureas1
- Tolbutamide (Orinase)
- Chlorpropamide (Diabenese)
- Tolazamide (Tolinase)
- Acetohexamide (Dymelor)
Second Generation Sulfonylureas1
- Glipizide (Glucotrol)
- Glipizide extended release (Glucotrol XL)
- Glyburide (Micronase, Diabeta)
- Glyburide (micronized) (Glynase PresTab)
- Glyburide/metformin (Glucovance)
- Glimepiride (Amaryl)
Meglitinides
- Repaglinide (Prandin)
- Nateglinide (Starlix)
Alpha Glucosidase Inhibitors
- Acarbose (Precose)
- Miglitol (Glyset)
Biguanides
- Metformin (Glucophage)
- Metformin extended release (Glucophage XR)
- Glyburide/metformin (Glucovance)
Thiazolidinediones2
- Rosiglitazone (Avandia)
- Pioglitazone (Actos)
1Sulfonylureas act by stimulating endogenous insulin production by the pancreas. Proper selection, dosages, and patient education are important to avoid hypoglycemic episodes. The most common side effects, aside from hypoglycemia, are gastrointestinal (GI) disturbances, which tend to be dose related and disappear when dosage is decreased. Sulfonylureas have been associated with rare occurrences of cholestatic jaundice and hepatitis; if either condition occurs, the sulfonylurea should be discontinued. All sulfonylureas are contraindicated in diabetic ketoacidosis (DKA).
2Troglitazone (Rezulin) was removed from the market in March 2000 by the U.S. Food and Drug Administration (FDA) after being linked to liver failure, liver transplants, and deaths.
Insulin
Regular testing of blood glucose and HbA1c is recommended to assess medication effect.
- Very short acting (lispro/humalog)
- Short acting (Regular)
- Intermediate acting (Neutral protamine Hagedorn [NPH]/Lente)
- Long acting (insulin glargine)
- Long acting (Ultralente)
Reduced hyperglycemia and an improvement in glucose toxicity will occur in type 2 diabetes, given sufficient doses of insulin. Individuals with moderately severe type 2 disease, defined as a fasting plasma glucose 140-200 mg/dl, will often show sufficient response to a single or twice-daily dose of insulin.
One study has suggested that bedtime administration is most effective when using intermediate-acting insulin. Another study suggested that 9:00 p.m. is a reasonable time for the single daily insulin dose when used in combination with sulfonylureas. The former study reported improved glycemic control, and the latter study reported less weight gain with the bedtime or evening insulin doses when compared to morning insulin doses.
Individuals with severe type 2 diabetes, defined as a fasting plasma glucose >200 mg/dl, or those who have proved not responsive to the above-mentioned regimens, may require frequent insulin dosing. This usually requires the addition of short-acting insulin before meals.
The total daily insulin doses for type 2 diabetes may range from 0.4-1.2 U/kg/day. Please be aware that in insulin-resistant patients, doses of >1.5 U/kg/day may be required.
Total daily dosage for people with type 1 diabetes may range from 0.3-0.5 U/kg/day.
The degree of glucose lowering is dose-related. Studies have demonstrated a lowering of fasting glucose of up to 190 mg/dl from baseline in patients with type 2 diabetes treated with insulin.
Type 2 Diabetes Treatment Approach Principles
Optimal treatment for type 2 diabetes incorporates a multiple risk factor approach including self-management counseling, medical nutrition therapy, physical activity, weight reduction if appropriate, and the use of oral glucose lowering agents or insulin if necessary. Careful consideration needs to be given to ameliorating associated cardiovascular risk factors such as hypertension, smoking, and dyslipidemia.
When setting treatment goals for individuals with type 2 diabetes, it is important to consider the person’s ability to comprehend the regimen and assess the risk for severe hypoglycemia. Consider as well other factors that may optimize or minimize the treatment’s benefit including: advanced age, end-stage renal disease (ESRD), advanced cardiovascular or cerebrovascular disease, or other co-morbidities that may lead to reduced life span.
Achievement of normal or near normal blood glucose levels requires education in self-management techniques including:
- Self blood glucose monitoring
- Recognition, treatment, and prevention of hypoglycemia
- Prevention, early detection, and treatment of chronic complications
- Medical nutrition therapy
- Regular physical activity
- Reinforcement and continuing education
For individuals who have been unable to achieve optimal blood glucose control through dietary changes and regular physical activity, the use of a single antidiabetic oral agent is recommended. Sulfonylureas, metformin, meglitinides, alpha glucosidase inhibitors, and thiazolidinediones are all approved by the U.S. Food and Drug Administration (FDA) for monotherapy. The choice of a particular agent must depend however, on the individual’s characteristics. See the original guideline document for an algorithm to assist in the choice of a pharmaceutical agent.
In case of monotherapy failure, combination therapies may be attempted. If, despite the use of oral agent combination therapy glycemic control is not achieved or maintained, insulin must be used, either alone or in combination with an indicated oral drug regimen. The total daily insulin doses range from 0.4-1.2 U/kg/day. Please be aware that in insulin resistant patients, doses of > 1.5 U/kg/day may be required.
Choice of specific agents should be based on self-monitoring of blood glucose (SMBG) profiles and physician preference. Remember to evaluate the patient’s cardiac, renal, and hepatic function as appropriate for each oral agent. The choice of an additional agent depends on the patient’s SMBG patterns and clinical scenario. See the original guideline document for an algorithm on combination therapy in type 2 diabetes.
Cardiovascular Risk Reduction Guidelines
Summary of Cholesterol Lowering Therapy
While many organizations (National Cholesterol Education Program [NCEP], American Heart Association [AHA] and others) have developed guidelines for screening and treatment of hypercholesterolemia, controversy exists over specific screening recommendations. There is, however, agreement that reduction of elevated cholesterol levels, along with attention to all modifiable cardiac risk factors, will decrease the incidence of cardiovascular disease. Aggressive treatment of diabetic dyslipidemia will reduce the risk of coronary heart disease (CHD) in patients with diabetes.

- Since men and women with diabetes are considered to have
equal coronary heart disease (CHD) risk, age and sex are not considered risk
factors.
ACE Inhibitor Therapy in Diabetes
Evidence suggests that the use of an angiotensin-converting enzyme (ACE) inhibitor in individuals who are at high risk for cardiovascular events may reduce the rates of these events. This includes people with diabetes. Reductions have been seen in myocardial infarction, stroke, coronary revascularization, cardiac arrest, heart failure, and death rates. Evidence also suggests that treatment with an ACE inhibitor slows the progression of microalbuminuria among patients with type 1 diabetes, even if normotensive. Refer also to the Hypertension and Nephropathy sections.
Aspirin Therapy in Diabetes
Both men and women with diabetes have a two- to four-fold increased risk of dying from the complications of cardiovascular disease. Evidence suggests that aspirin therapy should be prescribed as a secondary prevention strategy and, if no contraindications exist, should also be used as a primary prevention strategy in men and women with diabetes. Use of aspirin has not been studied in individuals under the age of 30.
Recommendations*
- Aspirin therapy is indicated for all persons with diabetes, unless contraindications exist.
- Use enteric coated aspirin in doses up to 325 mg, once per day.
- People with aspirin allergy, bleeding tendency, anticoagulant therapy, recent gastrointestinal (GI) bleeding, and clinically active hepatic disease are not candidates for aspirin therapy.
*There continues to be controversy in the literature regarding the interaction between aspirin and angiotensin-converting enzyme (ACE) inhibitors.
Hypertension
Introduction
Hypertension contributes to the development and progression of chronic complications of diabetes. The primary goal of therapy for adults should be to decrease blood pressure to < 130/80. Epidemiological analysis of the United Kingdom Prospective Diabetes Study (UKPDS) showed a continuous relationship between the level of systolic blood pressure and the risk of stroke, diabetes-related deaths, heart failure, microvascular complications, and visual loss.
Lifestyle modifications such as weight loss, exercise, and prudent reduction of salt and alcohol should be a major aspect of treatment of hypertension. Home blood pressure monitors also have a role in helping to manage hypertension aggressively in people with diabetes. Medications should be added to lifestyle changes if those interventions are not successful in controlling hypertension.
The criteria for identification of hypertension in diabetes has been established by the American Diabetes Association (ADA) as a systolic blood pressure (SBP) equal to or greater than 130 mmHg, or a diastolic blood pressure (DBP) equal to or greater than 80 mmHg, or taking antihypertensive medication. The determination of hypertension is based on the average of two or more readings taken at each of two more visits after an initial screening. Isolated systolic hypertension is defined as a systolic blood pressure of 140 mmHg or greater with diastolic blood pressure below 90 mmHg. When systolic and diastolic blood pressures fall into different categories, the higher category should be used to determine the individual's blood pressure status. The American Diabetes Association (ADA) criteria for hypertension differ from the National Heart, Lung and Blood Institute (NHLBI) definition, which states that the presence of diabetes is considered a coronary heart disease (CHD) risk equivalent. The presence of diabetes confers a high risk of new coronary heart disease within ten years.
Benefit of Aggressive Treatment
The results of the United Kingdom Prospective Diabetes Study (UKPDS) blood pressure study indicate that aggressive treatment of even mild-to-moderate hypertension is beneficial. Continued reduction of blood pressure into the normal range resulted in fewer complications. Both systolic and diastolic hypertension markedly accelerate the progression of diabetic nephropathy. Control of hypertension has been demonstrated conclusively to reduce the rate and progression of nephropathy and to reduce the complications of cerebrovascular disease and cardiovascular disease.
Goals of Treatment
In non-pregnant diabetic patients > 18 years of age, the primary goal for therapy is to decrease blood pressure to and maintain it at < 130 mmHg systolic and < 80 mmHg diastolic. For patients with isolated systolic hypertension of > 180 mmHg, the initial goal is to decrease the systolic blood pressure to < 160 mmHg, and to lower the systolic pressure by 20 mmHg for those with systolic pressures between 160-179 mmHg. If these initial goals are met and well tolerated, further lowering to 140 mmHg may be indicated.

ACE Inhibitor Use
Evidence suggests that the use of an angiotensin-converting enzyme (ACE) inhibitor in individuals who are at high risk for cardiovascular events may reduce the rates of these events. This includes people with diabetes. Reductions have been seen in myocardial infarction, stroke, coronary revascularization, cardiac arrest, heart failure, and death rates. Evidence also suggests that treatment with an ACE inhibitor slows the progression of microalbuminuria among patients with type 1 diabetes, even if normotensive. Refer also to the Nephropathy section.
Diabetic Nephropathy Guidelines
The earliest clinical evidence of nephropathy is the appearance of low but abnormal levels (30-300 mg/day or 20-200 micrograms/min) of albumin in the urine, referred to as microalbuminuria. Microalbuminuria, a harbinger of renal failure and cardiovascular complications in diabetes, is an albumin concentration in the urine that is greater than normal (but is not detectable with common urine dipstick assays for protein).
Screening for Albuminuria
Routine screening for microalbumin should be performed yearly in adults with type 2 diabetes. If the screening is positive for microalbumin, a quantitative measure is helpful in developing a treatment plan.
After the initial screening and in the absence of previously demonstrated microalbuminuria, a test for the presence of microalbuminuria should be performed annually.
Three methods to screen for microalbuminuria are shown below:
- Measurement of the albumin to creatinine ratio in
a random spot collection
- 24-hour urine collection with creatinine, allowing the
simultaneous measurement of creatinine clearance
- Timed (4-hour or overnight) urine collection
The first method is often preferred in an office-based setting and generally provides accurate information. There is marked day-to-day variability in albumin excretion, so at least 2 of 3 samples done in a 3- to 6-month period should show elevated levels before designating a patient as having microalbuminuria. If normal, repeat yearly.
Screening for microalbumin with dipsticks or reagent tablets may also be done if assays are not readily available. Reagents and tablets show a 95% sensitivity when performed by trained personnel. All positive tests by reagent strips or tablets should be confirmed using one of the quantitative urine assays listed below.

Several factors may influence the albumin excretion rate. Screening should be postponed in the following situations: short term hyperglycemia, exercise, marked hypertension, urinary tract infection, acute febrile illness, or heart failure. Angiotensin-converting enzyme (ACE) inhibitors or nonsteroidal anti-inflammatory drugs (NSAIDs) may also influence results.
Hypertension and Nephropathy
Both systolic and diastolic hypertension markedly accelerate the progression of diabetic nephropathy. Control of hypertension--regardless of agent used--has been demonstrated conclusively to reduce the rate and progression of nephropathy and to reduce the complications of cerebrovascular disease and cardiovascular disease. Refer also to the Cardiovascular and Hypertension sections.
In patients with underlying nephropathy, treatment with ACE inhibitors should also be part of initial therapy. Angiotensin-converting enzyme inhibitors are recommended for all type 1 patients with microalbuminuria, even if normotensive. The use of ACE inhibitors in normotensive type 2 diabetic patients is less well substantiated. For type 2 patients with hypertension or progressive albuminuria, ACE inhibitors are recommended. When ACE inhibitors are contraindicated, other antihypertensive agents should be used. Angiotensin II receptor blockers are being studied in humans with regard to renal protective effects.
Foot Inspection and Monofilament Use Guidelines
- A visual foot examination is recommended at every visit.
- A more in-depth inspection should be performed at least annually to identify high-risk foot conditions.
- An in-depth exam should include an assessment of:
- Protective sensation
- Vascular status
- Skin integrity
- Foot structure/biomechanics
Risk Identification
Amputation is most commonly the eventual result of previous minor trauma causing foot injury. The two most common causes of minor foot trauma are ill-fitting new shoes and improper cutting of toenails. The risk of ulcers or amputations is increased in people who have had diabetes >10 years, are male, have poor glucose control, smoke, or have cardiovascular, retinal, or renal complications. Four foot-related conditions are associated with amputation:
- Peripheral neuropathy
- Peripheral vascular disease (PVD)
- History of ulcers or amputation in the other limb
- Altered biomechanics
- Evidence of increased pressure (callus,
erythema)
- Limited joint mobility, bony deformity, or nail pathology
Assessing Protective Sensation
(Use either the Semmes-Weinstein monofilament or a tuning fork.)
- Have the patient look away or close his or her
eyes.
- Hold the filament perpendicular to the skin.
- Avoiding any ulcers, calluses or sores, touch
the monofilament to the skin until it bends. Hold in place for
approximately 1.5 seconds, then gently remove it.
- Randomly test the sites shown on the foot
diagram provided in the original guideline document.
- Elicit a response from the patient at each
site. Lack of sensation at any site may indicate diabetic neuropathy.
- The monofilament may be cleaned with 1:10 sodium hypochlorite solution if contaminated with blood or body fluids.
Risk Category
Low Risk
All of the following:
- Intact protective sensation
- Pedal pulses present
- No severe deformity
- No prior foot ulcer
- No amputation
High Risk
One or more of the following:
- Loss of protective sensation
- Absent pedal pulses
- Severe foot deformity
- History of foot ulcer
- Prior amputation
Management Guidelines
Low Risk
- Visual foot exam every routine diabetes
visit
- Annual comprehensive lower extremity
sensory exam
- Assess/recommend appropriate footwear
- Provide patient education for preventive
self-care
High Risk
- Conduct comprehensive lower extremity exam
every 3-6 months
- Demonstrate preventive self-care of the
feet
- Refer to specialists and diabetes educator
as indicated
- Assess/prescribe appropriate footwear
- Certify Medicare patients for therapeutic
shoe benefits
- Note "High Risk Feet" on medical
record
See the original guideline document for a list of monofilament resources.
Medical Nutrition Therapy
Purpose
To assist patients in acquiring and maintaining the knowledge, skills, and behaviors to successfully meet the challenges of daily diabetes self-management.
Without adequate nutrition advice or an individualized meal plan, patients may have difficulty achieving optimal blood glucose control.
Goals
- Achieve and maintain near normal blood glucose
levels by balancing food intake with medication and physical activity
- Achieve optimal serum lipid levels
- Provide adequate calories for attaining and
maintaining reasonable weight
- Prevent and treat the acute and long-term
complications of diabetes
- Improve overall health through optimum nutrition
Basic Education
For newly diagnosed patients or patients not recently educated about their diabetes. Basic survival skills should include:
- Relationship of food and meals to blood glucose
levels, medication, and activity
- Basic food/meal plan guidelines
- Consistent times each day for meals and snacks
- Recognition, prevention, and treatment of
hypoglycemia
- Sick day management
- Self-monitoring of blood glucose
Essential Education for Ongoing Nutrition Self-Management
For patients recently diagnosed with diabetes who have been taught basic survival skills or those who have not received current nutrition education. Others who may benefit from nutrition self-management education include patients having difficulties with diabetes management or those experiencing changes in lifestyle, medication, weight, or childbearing status. Follow-up sessions should focus on increasing the patient's knowledge, skills, and flexibility as he or she gains experience living with diabetes.
- Sources of nutrients and their effect on blood
glucose and lipid levels
