Millions of people have Type 2 diabetes without knowing it. Here are the warning signs — and when to get tested.
General information, not medical advice — see terms of use.
Type 2 diabetes often develops gradually with no symptoms in the early stages. When symptoms appear:
Classic symptoms:
- Frequent urination, especially at night
- Excessive thirst
- Unexplained weight loss despite normal appetite
- Increased hunger
- Fatigue and low energy
- Blurred vision
- Slow-healing cuts or bruises
- Frequent infections
- Numbness or tingling in hands or feet
- Darkened skin in creases of neck or armpits (sign of insulin resistance)
Diagnosis: A fasting blood glucose of 126 mg/dL or higher, or an HbA1c of 6.5%+ on two separate tests, confirms diabetes. A level between 100–125 mg/dL fasting (HbA1c 5.7–6.4%) indicates prediabetes.
Risk factors warranting testing even without symptoms: BMI over 25, age 45+, family history, history of gestational diabetes, high blood pressure, or physical inactivity.
Follow-up questions
Can Type 2 diabetes be reversed?
Type 2 diabetes can go into remission through significant weight loss (10–15% of body weight), a low-calorie or low-carbohydrate diet, and regular exercise. Remission is most achievable early in the disease.
What is the difference between Type 1 and Type 2 diabetes?
Type 1 is an autoimmune condition where the body produces no insulin, requiring lifelong insulin therapy. Type 2 is characterized by insulin resistance and accounts for 90–95% of all diabetes cases.
How often should you be tested for diabetes?
Adults 45+ should be tested every 3 years. Adults with risk factors (overweight, family history, high blood pressure) should be tested earlier and more frequently. Testing is a simple fasting blood test or HbA1c blood test.
