In short
- Three ways to be diagnosed. Fasting glucose 100 to 125 mg/dL, HbA1c 5.7 to 6.4 percent, or a two hour glucose of 140 to 199.
- Roughly 5 to 10 in 100 progress each year to type 2 diabetes if nothing changes.
- The intervention that works is specific. 7 percent weight loss and 150 minutes of activity a week cut progression by 58 percent in two landmark trials.
- Weight and blood sugar drive each other. Which is why they are treated together, not one at a time.
- Medication exists for higher risk. Usually metformin, after a proper trial of the rest.
Condition Overview
Prediabetes means blood sugar is above the normal range but below the threshold for type 2 diabetes, usually identified by HbA1c or fasting glucose. It often appears alongside weight gain around the abdomen, and the relationship runs both ways: rising weight worsens insulin resistance, and high insulin makes weight harder to lose.
Most patients feel entirely well and are surprised by the result. Others notice tiredness after meals or slower recovery from training. A private consultation is appropriate because this stage needs interpretation and a plan rather than a repeat test in a year. Left alone, a meaningful proportion of patients progress. Treated, many return to normal. The starting point is usually a metabolic weight loss program.
When to See a Doctor
- You have been told your HbA1c or fasting glucose is borderline or in the prediabetic range.
- Your weight has increased over the same period that your blood sugar has drifted upward.
- A close family member has type 2 diabetes and your own results are moving in that direction.
- You had gestational diabetes in a previous pregnancy, which raises later risk substantially.
- You want the result acted on now rather than repeated in twelve months to see what happened.
- You have marked thirst, frequent urination, blurred vision or unintended weight loss, which suggest diabetes rather than prediabetes and need prompt assessment.
- You have chest pain or breathlessness on exertion alongside these results, which needs cardiac assessment before any weight programme.
How Dr. Felix Assesses This
-
1
Goals and history
Your previous blood results and when they changed, your weight history over the same period, family history of diabetes, gestational diabetes if relevant, alcohol, sleep, shift work and how you currently eat and train.
-
2
Medical review
Examination, blood pressure, waist measurement and body composition, with blood work covering HbA1c, fasting glucose, a full lipid profile, liver, kidney and thyroid function, and further testing where the picture justifies it.
-
3
Suitability decision
Dr. Felix explains exactly where your numbers sit relative to the diagnostic thresholds, how much of the problem is weight driven, and whether treatment should be lifestyle led, medication supported or both.
-
4
Personal plan
A written plan targeting blood sugar and weight together: protein and carbohydrate structure, resistance training, sleep and alcohol, any medicine agreed with its dose steps, and a dated retest of HbA1c.

Why Early Treatment Can Matter
Prediabetes is one of the clearest examples of a condition where the stage you treat it at changes the outcome. Blood sugar in this range frequently returns to normal with weight reduction, resistance training and better sleep, and the improvement tends to hold while those changes hold.
Once type 2 diabetes is established, the target changes from reversal to control, and treatment usually becomes lifelong. There is no emergency here and no need for alarm. It simply means a consultation now is aimed at a better outcome than the same consultation after the threshold is crossed.

Numbers can return to normal
Blood sugar in the prediabetic range often normalises with weight and training changes.
What progression means
Type 2 diabetes brings lifelong treatment and additional cardiovascular and kidney risk.
Treat two problems once
Weight and blood sugar respond to the same plan when addressed together.
Cost & Consultation Investment
The consultation includes examination, body composition and the blood work needed to place your results accurately, since a single reading is rarely enough to act on. What follows depends on whether medication forms part of the plan and how closely you want the numbers followed. The pricing page carries current figures and describes what the first appointment covers.
Frequently Asked Questions
A fasting glucose of 100 to 125 mg/dL, an HbA1c of 5.7 to 6.4 percent, or a two hour glucose of 140 to 199 mg/dL after a glucose load. Any one of the three is enough to make the diagnosis.
Roughly 5 to 10 in 100 adults with prediabetes progress to type 2 diabetes each year without intervention. Having both an impaired fasting glucose and an impaired two hour value carries higher risk than either alone.
Frequently, yes. Returning blood sugar to the normal range is a realistic target at this stage, which is the reason for taking a borderline result seriously rather than filing it.
The trials used 7 percent of body weight. For a 95 kg person that is about 6.5 kg. Combined with 150 minutes of weekly activity, that reduced progression to diabetes by 58 percent.
150 minutes a week was the trial target, and resistance training is included here because muscle is the main destination for glucose. Walking counts towards the minutes but does not build muscle.
It is usually considered after about a year of proper lifestyle work, for people at higher risk of progressing: an HbA1c around 6 percent or above, a history of gestational diabetes, or several risk factors together. It can also be discussed earlier if you prefer.
That has not been clearly shown. Trials prove that diabetes is prevented or delayed, but neither lifestyle change nor medication has clearly reduced cardiovascular events or deaths in this group. Blood pressure and lipids are therefore treated on their own merits.
Yes, considerably. It raises long term risk of type 2 diabetes and is one of the factors that moves you into the higher risk group where medication is considered sooner.
HbA1c at around three months while you are making changes, since it reflects that period, then every three to six months and at least annually once things are stable.
Digestive upset is common early and is dose related, which is why it starts at 500 mg once daily with the evening meal and builds up. Long term use can lower vitamin B12, so that is checked periodically.
Where obesity is the dominant problem, that is often the more logical route, and it is a reasonable alternative to metformin. Which one fits is decided with you at the consultation.
It depends on the investigations you need and whether medication becomes part of the plan, so a single figure would be misleading. You get the full cost in the consultation before anything starts.
