Blood sugar
What does a dietitian do for prediabetes?
A registered dietitian turns your lab results and daily routine into an eating plan you can actually follow. Your doctor confirms the diagnosis and tracks your blood sugar; the dietitian handles the food side and checks in as you go.

What is prediabetes?
Prediabetes means your blood sugar is higher than normal but not yet in the diabetes range. An A1c of 5.7 to 6.4 falls in the prediabetes range, and so does a fasting glucose of 100 to 125.
It is common. The CDC says more than 2 in 5 US adults have it, and most do not know. It usually causes no symptoms, so it is found on a blood test.
Your doctor makes the diagnosis and may repeat the test to confirm it.
What does a dietitian actually do?
A dietitian looks at your labs, history and habits, picks the changes most worth making, and builds a plan around them. Then you meet again to see what worked.
- Go over your A1c, glucose and cholesterol results with you in plain language.
- Ask about your meals, work hours, family, cooking skills and budget.
- Choose a few specific changes, such as how to build a balanced plate or what to drink.
- Look at other things that affect blood sugar, such as sleep, stress and activity, and point you to your doctor when they need medical care.
- Review progress and adjust the plan at each visit.
What does the eating advice look like?
Common starting points are smaller portions, water instead of sweetened drinks, and plates built around vegetables, high-fiber carbohydrate foods and protein. The exact mix depends on you.
NIDDK notes that losing weight, being more active and following a reduced-calorie eating plan can lower the chance of developing type 2 diabetes. Those are the general ideas. A dietitian turns them into specific meals.
The CDC also points people to the National Diabetes Prevention Program once a doctor confirms prediabetes. A dietitian can work alongside that if you want one-on-one help.
When should you see your doctor first?
See your doctor if you have not been tested, or if you have signs of high blood sugar like constant thirst, frequent urination or blurred vision.
- You have risk factors, such as family history or extra weight, and have never had your A1c checked.
- Your A1c is 6.5 or above, which is in the diabetes range.
- You take diabetes medicine. Do not change it without your prescriber.
How do you start?
A first visit ($140, self-pay) is where to bring your latest A1c or glucose result.
For ongoing check-ins, the Personalized Care Plan is $600 a month.
What patients say about this kind of care
One patient working on prediabetes describes having gut symptoms looked at in the same plan.
“She's helping not only with my pre-diabetes, but also with previously confusing gut issues.”
One patient managing diabetes said the dietitian works to identify root causes and then creates an action plan.
“She works with you to identify the root causes and then creates an action plan.”
One patient described a first visit in which the dietitian took time to get to know them and explained the next steps.
“She took the time to get to know me and explained next steps.”

Frequently asked questions
Does prediabetes always turn into diabetes?
No. NIDDK says weight, activity and eating changes can lower the chance of developing type 2 diabetes. Your doctor can recheck your numbers over time.
Should I join the National Diabetes Prevention Program?
The CDC points people to it once a doctor confirms prediabetes. A dietitian can work alongside it if you want one-on-one help.
How often should I see a dietitian?
It varies. Many people meet more often at first, then space visits out as habits settle in.
How often should prediabetes be retested?
MedlinePlus says people with prediabetes are often retested every 1 to 2 years. Your doctor sets the schedule that fits you.
