Diabetes
Prediabetes
Glucose above normal but below the diabetes threshold. The stage where what you do next genuinely changes the outcome.
What the result means
Prediabetes means insulin resistance is already established and the pancreas is compensating for it, but glucose has not yet crossed the line that defines diabetes. It is a description of where you are on a continuum, not a separate disease.
Two things follow from that. The first is encouraging: this is the point at which intervention works best, and progression is not inevitable. The second is less comfortable: the elevated cardiovascular risk that comes with diabetes has already begun. Prediabetes is not a warning of future risk so much as the early part of present risk.
What the evidence shows
This is one of the better-studied questions in medicine. In the Diabetes Prevention Program — a large randomised trial in people with prediabetes — an intensive lifestyle programme aimed at modest weight loss and regular activity reduced progression to type 2 diabetes by 58% over about three years. Metformin reduced it by 31% in the same trial. Lifestyle change outperformed the drug, and the difference persisted on long-term follow-up.
The weight loss involved was moderate, in the region of 5 to 7% of body weight, not a transformation. The activity target was around 150 minutes a week of moderate exercise — brisk walking counts. These are ordinary numbers, and that is the point.
What to do about it
The eating changes that work are not exotic and do not require imported food. They centre on the quantity and type of carbohydrate: smaller portions of rice and roti, more of the plate given over to vegetables and protein, and fewer of the refined carbohydrates and sugary drinks that spike glucose hardest. The meal plans on this site are built around food available in any Lahore market.
Activity works partly independently of weight loss — muscle takes up glucose during and after exercise regardless of what the scale says. Something most days beats an intense session once a week.
Metformin is considered in some circumstances, particularly for people who are younger, have a higher BMI, or have had gestational diabetes. It is not automatic, and it does not replace the lifestyle work.
Follow-up
Prediabetes should be rechecked at least annually — sooner if there are symptoms or if risk factors change. Blood pressure and cholesterol should be assessed at the same time, because the cardiovascular risk that comes with insulin resistance does not wait for the glucose to cross a threshold.
Common questions
- Is prediabetes actually serious?
- Yes, in two ways. A meaningful proportion of people progress to type 2 diabetes each year without intervention, and the raised cardiovascular risk is already present. It is also the stage at which action is most effective.
- Can it go back to normal?
- Often, yes. Returning glucose to the normal range is realistic with sustained weight loss and activity, and is far more achievable at this stage than after diabetes is established.
- Do I need medicine?
- Usually not at first. Lifestyle change outperformed metformin in the largest trial of this question. Metformin is considered in specific situations, and that is a decision to make with your clinician rather than a default.
