🩺 What to Do After a
High Blood Sugar or Pre-Diabetes Result

Pre-diabetes is not diabetes. It is a window of opportunity — the body is showing signs of insulin resistance, but the damage is still reversible. Studies show that 5–10% weight loss and regular exercise returns the majority of pre-diabetic people to normal blood sugar within 12 months.

What This Result Actually Means

Pre-diabetes means your blood glucose is higher than normal but not yet in the diabetic range: fasting blood glucose between 6.1–6.9 mmol/L (impaired fasting glucose), or HbA1c between 42–47 mmol/mol (6.0–6.4%). This indicates insulin resistance — your cells are not responding efficiently to insulin, so more insulin is needed to process the same amount of glucose. Left unchecked, pre-diabetes progresses to Type 2 diabetes in 30–50% of people within 5 years. The good news: with intentional lifestyle change, a significant proportion of pre-diabetic individuals return to normal.

Your Next Steps — In Order

1
Confirm the result — get a repeat fasting glucose and HbA1c
A single elevated reading can be a laboratory error or reflect a stressful week. Confirm pre-diabetes with at least one repeat test. HbA1c is particularly useful as it reflects average blood sugar over 3 months and is unaffected by a single bad day.
2
Set a weight loss target if you are overweight
Losing 5–10% of body weight is the single most evidence-based intervention for pre-diabetes. For a 90 kg person, that means 4.5–9 kg. This sounds difficult but is achievable over 3–6 months with consistent effort. Weight loss primarily improves insulin sensitivity in the liver and muscles.
3
Change what you eat — reduce refined carbohydrates
Replace white rice, white bread, eba, and fufu with smaller portions of complex carbohydrates: brown rice, whole-wheat bread, oats, unripe plantain, boiled yam (in smaller portions). Add more vegetables. Reduce fruit juice (high sugar load despite being natural). Stop highly processed snacks and sugary drinks. You do not need to eliminate carbohydrates — you need to reduce quantity and choose lower glycaemic index options.
4
Exercise for at least 150 minutes per week
Walking briskly for 30 minutes five days a week lowers blood sugar independently of weight loss by improving muscle glucose uptake. Resistance training (bodyweight exercises, gym) additionally improves insulin sensitivity. Even breaking up prolonged sitting with a 10-minute walk after each meal reduces post-meal blood sugar spikes significantly.
5
Consider metformin if lifestyle change alone is insufficient
For high-risk pre-diabetic individuals (HbA1c at the upper end of the pre-diabetic range, significant family history, previous gestational diabetes, or obesity), metformin use alongside lifestyle change reduces progression to diabetes by an additional 31% beyond lifestyle alone. Discuss this option with your doctor — it is safe, inexpensive, and well-tolerated.
6
Retest in 3–6 months to track progress
Book a repeat fasting glucose and HbA1c in 3–6 months. Seeing your numbers improve is motivating and confirms the lifestyle changes are working. Consistently normal results for 12 months mean you have achieved pre-diabetes remission — though annual monitoring should continue.

Frequently Asked Questions

Can pre-diabetes be fully reversed?
Yes — this is one of the most encouraging facts in medicine. Pre-diabetes is not inevitable progression to full diabetes. With sufficient weight loss, dietary change, and regular exercise, many people return their blood glucose to the completely normal range and maintain it there. The key variable is timing: the earlier pre-diabetes is detected and addressed, the greater the chance of full reversal. People who achieve remission still have a lifetime increased risk of diabetes and need annual monitoring.
What foods should I avoid with pre-diabetes in Nigeria?
Focus on reducing rather than eliminating. Priority reductions: sugary drinks (Fanta, Malt, Lucozade, even fresh juice), white rice in large portions (a cup of dry white rice has a very high glycaemic load), heavily processed snacks (chin chin, biscuits, pastries), eba and fufu in large quantities (very high carbohydrate), and alcohol (especially beer and palm wine). Priority additions: more vegetables with every meal, more fish and lean protein, more legumes (beans, lentils), smaller portions of complex carbohydrates, and water as the primary drink.
My fasting glucose was 6.7 — do I have diabetes?
6.7 mmol/L falls in the impaired fasting glucose range (6.1–6.9 mmol/L) — pre-diabetes, not diabetes. The diabetes threshold is 7.0 mmol/L on two occasions. However, 6.7 is at the higher end of pre-diabetes and warrants an HbA1c to confirm, and prompt lifestyle intervention. Do not wait to address it.
Does pre-diabetes cause any symptoms?
Usually not — this is what makes it a silent risk. Some people notice increased thirst, slightly increased urination, or fatigue, but these are vague and easily attributed to other causes. The majority of pre-diabetic individuals feel completely well, which is why screening is so important: a fasting blood glucose test at age 35–40 (or earlier with a family history or obesity) could catch the condition before any damage is done.
