The early signs of high blood sugar and diabetes can be subtle at first. The most common early symptoms include frequent urination (especially at night), unusual thirst that doesn't go away, unexplained fatigue, and blurry vision.

Some people also notice that cuts or bruises heal more slowly than usual, or they experience tingling and numbness in the hands or feet. Unexplained weight loss can occur in type 1 diabetes, while type 2 often develops more gradually with symptoms that are easy to overlook.

The tricky part is that many people with prediabetes or early type 2 diabetes have no symptoms at all — which is why regular blood sugar testing is so important, especially if you have risk factors.

Prediabetes means your blood sugar levels are higher than normal, but not yet high enough to be classified as type 2 diabetes. It's essentially an early warning stage — and a very important one, because it's often reversible.

Prediabetes symptoms are often absent, which is why it's called a "silent" condition. Many people only discover it through a routine blood test. However, some people do experience increased thirst, mild fatigue, or darkening of skin in body creases (a condition called acanthosis nigricans).

If you're wondering "do I have prediabetes?", the most reliable way to know is a fasting blood glucose test or HbA1c test from your doctor. A fasting glucose between 100–125 mg/dL, or an HbA1c between 5.7–6.4%, indicates prediabetes. This quiz can help you assess whether testing makes sense for you.

Understanding your diabetes risk factors is the first step toward prevention. The major ones include:

Non-modifiable factors: Age (risk rises after 45), family history of type 2 diabetes, ethnicity (higher rates in South Asian, African American, Hispanic, and Native American communities), and history of gestational diabetes.

Modifiable factors: Being overweight or obese (particularly around the abdomen), physical inactivity, a diet high in refined carbohydrates and sugary drinks, high blood pressure, and abnormal cholesterol levels.

The good news? Most of the modifiable risk factors are within your control. Even modest improvements — losing 5–7% of body weight, walking 30 minutes most days — can dramatically reduce your risk.

Absolutely — and this is one of the most encouraging things about prediabetes. Research consistently shows that lifestyle changes can reduce the risk of prediabetes progressing to type 2 diabetes by 58% (and even higher in some groups).

The key strategies that work: regular physical activity (aim for 150 minutes of moderate exercise per week), reducing portion sizes and limiting sugary and ultra-processed foods, prioritizing whole grains, vegetables, and lean protein, losing even a small amount of weight if you're overweight, and improving sleep quality (poor sleep affects blood sugar regulation).

For many people, even if they do develop type 2 diabetes, early detection means the condition can be managed effectively and complications largely prevented. The most important thing you can do is get tested and know your numbers.

No — and we want to be completely transparent about this. This quiz is not a diagnostic tool. It's a screening aid based on common risk factors and symptoms, designed to help you decide whether to speak with a doctor.

Diabetes is formally diagnosed using one or more of these blood tests: a fasting blood glucose test (diabetes: ≥126 mg/dL on two separate occasions), a random blood glucose test (≥200 mg/dL with symptoms), an HbA1c test (diabetes: ≥6.5%), or an oral glucose tolerance test.

If you're wondering "how do I know if I have diabetes?", the honest answer is: only a blood test can tell you for certain. Many people feel fine and still have elevated blood sugar. If this quiz raised any flags, or if you simply haven't had blood work done recently, booking a check-up is the smartest next step you can take for your health.
