Your primary care provider (PCP) can screen you for prediabetes, confirm the diagnosis with a simple blood test, refer you to a structured lifestyle program, and prescribe medication when your risk profile calls for it. The single most important step you can take at your next visit: ask your PCP to review your A1C or fasting glucose result and discuss whether you qualify for the CDC National Diabetes Prevention Program (National DPP).

What your PCP can do for prediabetes in primary care:

• Screen and diagnose using A1C, fasting plasma glucose (FPG), or an oral glucose tolerance test (OGTT)
• Refer or enroll you in a CDC-recognized National DPP or a digital equivalent
• Prescribe metformin for selected higher-risk patients after shared decision-making
• Set a monitoring plan with annual or more frequent lab checks
• Coordinate referrals to a registered dietitian (RDN), diabetes care and education specialist, or endocrinologist when needed

Despite this clear pathway, only about 23% of patients with prediabetes had a documented treatment plan in a national ambulatory care sample. That gap means you may need to advocate for yourself at your visit.

How primary care screens and diagnoses prediabetes

Three standard blood tests define prediabetes. The ADA Standards of Care in Diabetes 2025 set the numeric thresholds below, and any one of the three is sufficient for diagnosis.

The A1C is the most common starting point in primary care because it requires no fasting and reflects average glucose over roughly three months. The OGTT is less routine in primary care offices but may be ordered when A1C results are borderline or when conditions like anemia, hemoglobin variants, or kidney disease could distort A1C accuracy. In those cases, your PCP may rely on FPG or OGTT instead.

Who should be screened? The USPSTF and ADA both recommend testing adults who meet any of the following criteria:

• Age 35–70 with overweight (BMI ≥25) or obesity (BMI ≥30)
• Any age with a first-degree relative with type 2 diabetes
• History of gestational diabetes mellitus (GDM)
• Polycystic ovary syndrome (PCOS)
• Hypertension or treatment for high blood pressure
• HDL cholesterol below 35 mg/dL or triglycerides above 250 mg/dL
• Certain racial and ethnic backgrounds (Black, Hispanic/Latino, Asian American, American Indian, Alaska Native, Pacific Islander) at lower BMI thresholds
• Prior A1C of 5.7%–6.4% or impaired fasting glucose on a previous test

Retesting intervals depend on your current result and overall risk:

1. Normal A1C with low risk factors: retest every three years
2. A1C at the lower end of prediabetes (5.7%–6.0%) with stable lifestyle: retest annually
3. A1C at the higher end (6.1%–6.4%) or rising values: retest every three to six months
4. After starting metformin or a structured lifestyle program: retest at three to six months to assess response

First-line management your PCP can offer for prediabetes

Structured lifestyle change is the first-line treatment for prediabetes, and the evidence behind it is substantial. The original Diabetes Prevention Program (DPP) trial showed that an intensive lifestyle intervention reduced progression to type 2 diabetes by about 58% over three years. That figure comes from a rigorous randomized trial, not a modeling exercise.

The CDC National DPP translates that trial into a real-world, 12-month program. The program runs 16 weekly sessions in the first six months, followed by monthly maintenance sessions. CDC-recognized programs are available in person, online, and via telehealth, which matters for patients who face transportation or scheduling barriers.

Lifestyle targets your PCP will discuss with you:

• Achieve and sustain roughly 7% of body weight lost (about 14 lbs for a 200-lb person)
• Build to 150 minutes per week of moderate activity such as brisk walking
• Shift toward higher-quality carbohydrates: non-starchy vegetables, legumes, whole grains
• Reduce portion sizes and limit sugar-sweetened beverages
• Prioritize sleep and stress management, both of which affect glucose regulation

How your PCP refers you to the National DPP:

1. Your PCP confirms prediabetes with a qualifying lab result
2. The practice generates an electronic referral to a CDC-recognized DPP supplier (in-person, digital, or telehealth-based)
3. You receive enrollment instructions and a program start date
4. Your PCP orders baseline labs (A1C, lipids, kidney function) before you begin
5. Follow-up is scheduled at three to six months to review progress

Access barriers are real. Cost, program availability, and work schedules prevent many patients from completing a full 12-month program. Medicare covers the Medicare DPP for eligible beneficiaries, and many commercial insurers cover CDC-recognized programs. For patients who cannot access an in-person program, digital DPP platforms based on the same principles have shown projected reductions in diabetes onset of roughly 28–33% in modeled analyses. Lower-intensity options like brief text-message programs have not consistently moved A1C in short trials, so higher-intensity engagement tends to produce better results.

Pro Tip: When your PCP refers you to a DPP, ask specifically whether the program is CDC-recognized. That designation means it meets the evidence-based curriculum standards from the original trial, not just a general wellness class.

When your PCP may prescribe metformin for prediabetes

Metformin is not the default first step, but it is a well-supported option for selected patients. The DPP trial showed metformin reduced the risk of progressing to type 2 diabetes by roughly 31% over three years. Extended follow-up data from the DPP Outcomes Study (DPPOS) have not demonstrated a clear all-cause mortality benefit from metformin, so the conversation with your PCP should be grounded in realistic expectations.

Patients most likely to benefit from metformin for prediabetes:

• Age under 60 with BMI ≥35
• History of gestational diabetes
• A1C at the higher end of the prediabetes range (6.0%–6.4%)
• Rising glucose values despite lifestyle efforts
• Preference for adding medication alongside lifestyle change after shared decision-making

What to expect if your PCP prescribes metformin:

• Dosing typically starts low (500 mg once daily with a meal) and increases gradually to reduce GI side effects
• Common side effects include nausea, diarrhea, and stomach upset, especially early on
• Kidney function (creatinine/eGFR) is checked at baseline and periodically
• Long-term metformin use can reduce B12 absorption; your PCP should check B12 levels after 1–2 years of use
• Metformin is generally not used when eGFR falls below 30 mL/min/1.73m²

Pro Tip: Before your appointment, note whether you have any plans for pregnancy, since metformin is sometimes used in pregnancy but the conversation changes. Also bring your most recent kidney function results if you have them, so your PCP can assess candidacy without waiting for new labs.

How your PCP monitors you after a prediabetes diagnosis

Prediabetes does not stay static. Values can improve with lifestyle change, hold steady, or progress toward diabetes. A structured monitoring plan keeps your PCP informed and allows for timely adjustments.

Recommended monitoring cadence:

1. At diagnosis: A1C or FPG, fasting lipid panel, blood pressure, kidney function, and weight
2. Three to six months after starting a lifestyle program or metformin: repeat A1C or FPG to assess response
3. Annually (minimum): A1C, weight, blood pressure, and lipid review per ADA Standards of Care guidance
4. More frequently if A1C is rising, symptoms develop (increased thirst, urination, fatigue), or you have multiple comorbidities

Thresholds that trigger a diabetes diagnosis on two separate tests (or one test with symptoms):

• A1C ≥6.5%
• FPG ≥126 mg/dL
• 2-hour OGTT ≥200 mg/dL
• Random glucose ≥200 mg/dL with classic symptoms

Once those thresholds are crossed, your PCP will shift to a diabetes management framework, which typically includes more frequent monitoring, medication review, and referrals to diabetes care and education specialists.

What your PCP checks at each follow-up visit:

• Weight and BMI trend
• Blood pressure (target generally below 130/80 mmHg for most adults with metabolic risk)
• Lipid panel and whether statin therapy is appropriate
• Kidney function if on metformin
• B12 level if on long-term metformin
• Lifestyle progress: activity minutes, dietary changes, weight trajectory

How primary care coordinates your care team

Primary care is the hub, not the ceiling. Your PCP can manage most prediabetes care directly, but several referral pathways add meaningful value.

Referral types and when your PCP uses them:

• Registered Dietitian (RDN): Medical nutrition therapy from an RDN is covered by Medicare and many commercial plans for people with prediabetes. An RDN provides individualized meal planning that goes beyond general advice.
• Diabetes Care and Education Specialist (DCES): Structured diabetes self-management education (DSME) programs help patients build skills for glucose monitoring, medication adherence, and behavior change.
• Endocrinology: Referred when glucose values are difficult to manage, when the diagnosis is uncertain (type 1 vs. type 2 vs. MODY), or when comorbidities complicate treatment.
• Behavioral health: Stress, depression, and disordered eating all affect glucose regulation. PCPs increasingly co-locate or refer to behavioral health within the primary care setting.
• CDC National DPP or digital DPP: The most common referral for newly diagnosed prediabetes. Implementation research shows that EHR-integrated electronic referrals and brief follow-up messaging improve enrollment rates compared to verbal referrals alone.

Medicare DPP eligibility requires a diagnosis of prediabetes (qualifying lab result), BMI ≥25 (≥23 for certain Asian American populations), no previous diabetes diagnosis, and no prior Medicare DPP participation. Your PCP can check eligibility and generate the referral directly.

For care coordination across your full care team, primary care remains the consistent point of contact, tracking what each specialist recommends and making sure the plan stays coherent.

How prediabetes care changes for specific groups

Not every patient with prediabetes follows the same path. Primary care clinicians adjust screening intensity, treatment goals, and monitoring cadence based on individual circumstances.

Key groups and how care is tailored:

• Adults over 70: The benefit-to-risk calculation shifts. Aggressive glucose lowering carries more risk of hypoglycemia and falls in older adults, and life expectancy affects how much long-term prevention matters. Your PCP will weigh your functional status and goals of care before recommending intensive lifestyle programs or metformin. A senior health screening checklist can help you prepare for that conversation.
• Women with a history of gestational diabetes: GDM history carries a substantially higher baseline risk of progressing to type 2 diabetes. Screening should begin earlier (within one to three years postpartum), happen more frequently, and lifestyle intervention should start promptly after diagnosis.
• People with obesity and multiple comorbidities: Hypertension, dyslipidemia, sleep apnea, and fatty liver disease often cluster with prediabetes. Your PCP may prioritize weight-focused interventions, including GLP-1 receptor agonists for weight management, and will coordinate care across conditions rather than treating each in isolation.
• Younger adults (18–35): Earlier screening is warranted when risk factors are present. Lifestyle habits established now have decades of impact ahead. For younger patients, preventive care guidance can frame what to expect from a first prediabetes conversation with a PCP.

Pro Tip: If you fall into one of these groups, ask your PCP directly: “Given my history, how often should we recheck my A1C, and is there a reason to start treatment sooner or differently than the standard recommendation?”

What telehealth primary care can do for prediabetes management

Telehealth primary care handles the large majority of prediabetes management without requiring an in-person visit. The core clinical work, including lab ordering, medication management, lifestyle counseling, and DPP referrals, translates well to a secure video visit.

What a telehealth PCP can do for you:

• Order A1C, FPG, lipid panel, kidney function, and B12 labs at a local draw site
• Review results and discuss diagnosis, risk, and treatment options via video
• Generate electronic referrals to CDC-recognized or digital DPP programs
• Prescribe and manage metformin, including titration and side-effect monitoring
• Coordinate with RDNs, DCES programs, and behavioral health via e-referral
• Review connected device data (smart scales, step trackers, continuous glucose monitors) between visits
• Schedule structured follow-up at three to six month intervals

Where in-person care may still be needed:

• The OGTT requires a two-hour supervised draw, which most telehealth practices coordinate through a local lab or clinic
• Physical exam findings (foot exam, detailed cardiovascular assessment) require an in-person visit when clinically indicated
• Certain specialist procedures cannot be performed remotely

For a practical overview of managing glucose-related care through telehealth, the workflow is more straightforward than many patients expect.

Pro Tip: Before your telehealth visit, pull together your most recent lab results (even from another provider), your current medication list, your weight over the past three to six months, and a brief note on your typical diet and activity level. A PCP who has that information at the start of the visit can move directly to a plan rather than spending the visit gathering basics.

Questions to ask your PCP about prediabetes at your next visit

Walking into a primary care appointment with specific questions produces a more useful visit. Prediabetes is often asymptomatic, which means it can be deprioritized when other concerns fill the agenda. Being prepared changes that dynamic.

Questions to ask your PCP:

• “What is my current A1C, and where does it fall in the prediabetes range?”
• “Am I a candidate for the CDC National Diabetes Prevention Program, and can you refer me?”
• “Should I see a registered dietitian for medical nutrition therapy?”
• “Is metformin appropriate for me given my risk profile?”
• “How often should we recheck my A1C, and what number would change our plan?”
• “Should we check my B12 now as a baseline before starting metformin?”
• “Are there any comorbidities (blood pressure, cholesterol, weight) we should address at the same time?”

What to bring or prepare:

• Most recent lab results, including any prior A1C or glucose values
• Current medication list, including supplements
• Family history of type 2 diabetes or cardiovascular disease
• Weight history over the past six to twelve months
• A brief note on your current diet, activity level, and any barriers you face (schedule, cost, access)

On shared decision-making: lifestyle change alone is the preferred starting point for most patients. Adding metformin is a reasonable choice for higher-risk individuals who want an additional layer of protection or who have not achieved adequate lifestyle change after three to six months. Neither path is wrong. The goal is a plan you and your PCP agree on and that you can realistically follow.

What treating prediabetes in primary care actually looks like

Prediabetes rarely comes up as the reason a patient books an appointment. It surfaces in a lab result reviewed at an annual physical, or it appears in a chart flag that the clinician catches while managing blood pressure or weight. That is the clinical reality, and it shapes how care gets delivered.

The most useful thing a clinician can do in that moment is resist the urge to simply note the finding and move on. A brief, specific conversation, even five minutes, that ends with a lab order, a DPP referral, and a follow-up date is far more valuable than a general recommendation to “eat better and exercise.” Patients respond to concrete targets. “Walk 30 minutes five days a week and aim to lose 10 pounds over the next six months” is a plan. “Be more active” is not.

Metformin comes into the conversation when lifestyle change alone seems unlikely to be sufficient, when the A1C is at the higher end of the prediabetes range, or when the patient asks about it. The evidence supports offering it in those situations. What it does not do is replace lifestyle change, and that distinction matters in how the conversation is framed.

Early action, even modest action, produces real results. That is what the data from the DPP trial and its long-term follow-up consistently show.
