Prediabetes in Singapore: Normal Blood Sugar Levels and How to Lower Yours

Normal is below 6.1 fasting and below 7.8 at two hours, and Immority EvenOn serves this stage as a daily drink with your main meal, to act early and lower your risk.

Pre-diabetes has no symptoms (ACE), so a blood test is the only way to know you have it. The good news sits in the same guideline: a healthier diet and more activity cut the risk of type 2 diabetes by 31% to 37% over 2 to 6 years (ACE). Here are the normal numbers, the pre-diabetes ranges, the steps that lower blood sugar and where EvenOn fits.

What are normal blood sugar levels?

A normal fasting blood sugar is below 6.1 mmol/L, and a normal result two hours into an oral glucose tolerance test (OGTT) is below 7.8 mmol/L. The OGTT is a 75 g glucose drink with a blood test two hours later. Singapore’s ACE Clinical Guideline on pre-diabetes (Ministry of Health) sorts results like this:

• Normal: fasting below 6.1 mmol/L; 2-hour below 7.8 mmol/L; ACE
• Impaired fasting glucose (IFG): fasting 6.1 to 6.9 mmol/L; 2-hour below 7.8 mmol/L; ACE
• Impaired glucose tolerance (IGT): 2-hour 7.8 to 11.0 mmol/L; fasting below 7.0 mmol/L; ACE
• Diabetes: fasting 7.0 mmol/L or higher, or 2-hour 11.1 mmol/L or higher; the standard diagnostic thresholds

If a meter or website shows mg/dL, multiply mmol/L by 18: 7.0 mmol/L is 126 mg/dL. The 2-hour numbers are for the glucose drink test, not an ordinary meal, so ask your doctor what home readings after meals to aim for.

What is pre-diabetes?

Pre-diabetes means your blood sugar is higher than normal but still below the diabetes thresholds (ACE). It comes in two forms, impaired fasting glucose and impaired glucose tolerance, and it is common: around 14% of Singaporeans have impaired glucose tolerance (ACE). Left alone, it tends to move one way. Without lifestyle changes, at least 35% of people with pre-diabetes in Singapore progress to type 2 diabetes within eight years (ACE). That makes pre-diabetes the best window you will get to act: lifestyle intervention, a healthy diet and more activity, cuts the risk of developing type 2 diabetes by 31% to 37% over 2 to 6 years (ACE). Our type 2 diabetes guide explains insulin resistance and what comes after pre-diabetes.

How is pre-diabetes diagnosed in Singapore?

With fasting glucose and the OGTT, not HbA1c. In Singapore, HbA1c is not currently indicated as a diagnostic test for pre-diabetes (ACE), even though the HbA1c bands you see online, from the American Diabetes Association, put prediabetes at 5.7% to 6.4%. HbA1c may be used to screen for diabetes (MOH Circular No. 08/2019). In practice, ask your polyclinic, your GP or your Healthier SG family doctor for a fasting glucose test, and an OGTT if they advise one. Our HbA1c guide explains how to read that number.

What does high blood sugar feel like?

Often like nothing at all: pre-diabetes has no symptoms (ACE), and many people with diabetes have no signs either. When sugar runs high for longer, common signs are thirst, passing urine often, tiredness, blurred vision, slow-healing wounds, weight loss without trying, frequent hunger, numb or tingling hands and feet, dark velvety skin on the neck and skin tags. If you notice them, get tested rather than guess. If you already have diabetes, HealthHub advises seeing your doctor if your sugar stays above 16 mmol/L for over 24 hours.

How can you lower your blood sugar?

Eat to the ACE plate, swap sweet drinks for water, move at least 150 minutes a week and lose a little weight if you carry extra. In Singapore terms:

1. Build the plate: half vegetables and a small portion of fruit, a quarter lean protein, a quarter whole grains such as brown rice, oats or wholegrain bread (ACE). At the cai fan stall, pick two vegetables and one protein and ask for less rice; with chicken rice or nasi lemak, add a vegetable side.
2. Change the drink: water instead of sugar-sweetened drinks (ACE). Kopi or teh siew dai is a start, kosong is better, and bubble tea becomes a once-in-a-while drink.
3. Walk it off: at least 150 minutes of moderate exercise such as brisk walking a week, or 75 minutes vigorous, and no more than two days in a row without exercise (ACE). A walk after your biggest meal is an easy habit.
4. Trim the waist: aim for a BMI below 23, or a 5% to 10% weight loss if you are overweight (ACE).
5. Sleep and retest: keep regular sleep, and repeat the test your doctor advises so you can see the change.

Where does EvenOn fit if you have pre-diabetes?

EvenOn fits as early support next to these steps, not instead of them.

Immority EvenOn is a blood sugar balance drink from Immority. One 5 g sachet a day, stirred into water with your main meal, gives you 11 botanicals led by gymnema (25% gymnemic acid) and mulberry leaf (5% DNJ). It is halal (JAKIM) and classified as a food product by Malaysia’s NPRA, where it is made.

For pre-diabetes, the product page puts its role simply: act early and lower your diabetes risk. One sachet goes with the day’s biggest carb meal, so it works alongside that meal to ease the after-meal rise. Mulberry leaf flattens the after-meal peak, and the flyer says that for people with obesity or pre-diabetes it smooths the sugar curve at the source and improves glucose tolerance; gymnema dulls the sweet receptors, which helps with the kopi and kueh habit. The studies were on the ingredients: in a human study of mulberry leaf DNJ (Thaipitakwong et al., 2020), the blood sugar peak after a 50 g sugar drink was 59% lower than control, and a meta-analysis of 23 human trials in type 2 diabetes or pre-diabetes (Kesharwani et al., 2026) found fasting sugar, after-meal sugar and HbA1c lower. Our mulberry leaf guide goes deeper, and what Immority EvenOn is covers the full formula.

Already on medicine such as metformin, gliclazide or insulin? Keep taking it exactly as prescribed and never stop or change a dose on your own. Check your sugar more often in the first weeks, because readings may come down; people on insulin or gliclazide are the most at risk of going too low. The signs are shaking, sweating, a fast heartbeat, hunger and confusion. Below 4 mmol/L, follow the low-sugar plan your care team gave you, see your doctor if lows keep coming back (HealthHub), and tell your doctor you take EvenOn.

Frequently asked questions

Is a fasting blood sugar of 6.5 mmol/L normal? No. A fasting result of 6.1 to 6.9 mmol/L is impaired fasting glucose, one form of pre-diabetes (ACE). Ask your doctor to confirm it and plan your next test.

What is a normal blood sugar level after eating? Singapore’s guideline gives the 2-hour cut-off for the glucose drink test, below 7.8 mmol/L (ACE), not for ordinary meals. Ask your doctor what after-meal readings to aim for on a home meter.

How fast does pre-diabetes turn into diabetes? Without lifestyle changes, at least 35% of people with pre-diabetes in Singapore progress to type 2 diabetes within eight years (ACE). Lifestyle changes cut that risk by 31% to 37% (ACE).

Can EvenOn help with pre-diabetes? Yes, as early management: for pre-diabetes it helps you act early and lower your risk, alongside the ACE plate and exercise. Keep your sugar checks and tell your doctor you take EvenOn.
