Support early detection and monitoring of complication risks
In its early stages, diabetes may cause few or no noticeable symptoms and can remain undetected for years. Therefore, you should not wait until symptoms appear before getting tested.
When blood glucose levels become elevated, symptoms of diabetes may include:
- Excessive thirst
- Frequent urination
- Increased hunger
- Persistent fatigue
- Blurred vision
- Unexplained weight loss
- Numbness or tingling in the hands and feet
- Recurrent skin infections
- Fungal infections or genital itching
- Slow-healing wounds.
Healthcare professionals generally recommend diabetes screening every 3 years for adults aged 35 and above who have normal screening results and no major risk factors such as overweight, obesity, or a family history of diabetes.
For individuals who have been diagnosed with prediabetes, testing is generally recommended at least once a year to detect early progression to type 2 diabetes.
No. Gestational diabetes is diagnosed using blood glucose measurements from an oral glucose tolerance test (OGTT). This is the standard test specifically used during pregnancy and is typically performed between 24 and 28 weeks of gestation.
However, current international guidelines generally recommend that pregnant women have fasting blood glucose or HbA1c testing at their first prenatal visit to identify previously undiagnosed pre-existing diabetes, particularly if they have risk factors such as overweight, a personal history of gestational diabetes, or a family history of diabetes.
