10 early symptoms that can point to diabetes
The article says common warning signs can appear before diagnosis, and the CDC recommends testing adults age 35 and older.
In recognition of American Diabetes Month, the International Diabetes Federation 2026 and 2027 theme is "Early Action on Diabetes," highlighting 10 key symptoms like thirst and fatigue that may indicate undiagnosed conditions.
Testing recommendations differ slightly: the American Diabetes Association recommends screening all adults by age 35, while the U.S. Preventive Services Task Force suggests ages 35 to 70 for those who are overweight or have obesity.
Diagnostic thresholds include an A1C of 6.5% or higher for diabetes, whereas fasting plasma glucose levels between 100 mg and 125 mg indicate prediabetes, according to clinical guidelines.
For blood sugar staying at 300 mg or higher, patients should call 911, as emergency conditions like diabetic ketoacidosis and hyperosmolar hyperglycemic state require immediate medical attention.
The CDC reported 40.1 million people had diabetes in 2023, with another 115.2 million having prediabetes, underscoring the importance of recognizing symptoms such as blurry vision, frequent urination, and slow-healing sores.
