HbA1c and prediabetes: the number your doctor calls “borderline”
“Your result is 5,9, it’s borderline, watch your diet” — and you leave the office feeling “I got away with it.” You didn’t. 5,7-6,4% is prediabetes, a condition from which half of people progress to diabetes within 5-10 years. And at the same time — the last point when everything can be turned around with food, without a single pill, in three to six months. Section — blood sugar.
What HbA1c is
Blood sugar sticks to the hemoglobin of red blood cells, and the more sugar there is, the more “sugared” hemoglobin there is. A red blood cell lives for three months — so the number shows the average blood sugar over three months. One good morning will not fool it, and one celebration will not ruin it. This is the most honest blood sugar test, and you do not have to fast before taking it.
Ranges
| HbA1c | Average blood sugar | What it means | What to do |
|---|---|---|---|
| up to 5,3% | up to 5,7 | excellent | maintain |
| 5,4-5,6% | 5,8-6,3 | normal, but at the upper end | check fasting insulin |
| 5,7-6,4% | 6,5-7,7 | prediabetes | the method, retest in 3 months |
| 6,5% and above | 7,8+ | diabetes | doctor + method under supervision |

Why “borderline” means acting now
Prediabetes has no symptoms, and damage is already occurring: blood vessels, nerves, and kidneys suffer from blood sugar 6,5-7,5 years before diagnosis. At the same time, at this stage the pancreas is still working, and removing the burden — sugar and flour — is enough for everything to return to normal. With diabetes, some cells have already been lost, and remission is possible but more difficult. The difference between 5,9 and 6,5 is the difference between “food for six months” and “medication forever.” The swings that lead to this are blood sugar swings.
Three-month plan
Starting point
HbA1c, fasting glucose and insulin, lipid panel, ALT, waist circumference. Today.
Sugar and flour — zero
Not “less,” but zero: including juices, honey, and “healthy” cereals. This is the only lever that moves HbA1c quickly.
Three meals, a 14/10 window
Breaks allow insulin to fall. Snacks do not.
Walking after meals
15 minutes after each meal — muscles take up sugar.
Strength training twice
Muscle is the main consumer of glucose.
Retest in 3 months
HbA1c and insulin. A decrease of 0,3-0,5 works; continue until normal.
While taking medication — only with a doctor
- Metformin — compatible, dose determined by a doctor
- Sulfonylureas, insulin — risk of hypoglycemia, adjustment from the first week
- Check blood sugar at home in the morning and 2 hours after meals
- Dizziness, trembling, sweating — blood sugar is low: measure it and inform your doctor
Frequently asked questions
HbA1c 5,7 — is that already scary?
This is a reason to act, not a sentence. With the method, after 3 months it is usually 5,3-5,5. What is scary is doing nothing.
Can it be lowered without giving up bread?
With “less bread” — by 0,1-0,2. With zero — by 0,5-1. The difference is in the approach, not willpower.
Type 2 diabetes for 5 years — will the method help?
Remission is possible for a significant proportion of people, especially in the first years. Only with a doctor: medication doses decrease over weeks.
