What are the main signs and symptoms of prediabetes?

Prediabetes is an asymptomatic condition. Signs, or indications that an individual should undergo testing to determine whether they have prediabetes, include overweight or obesity in combination with at least one of the following risk factors: family history of diabetes, high-risk race/ethnicity (i.e., Black, Latino/Hispanic, Native American, Asian American, Pacific Islander), history of gestational diabetes, polycystic ovary syndrome, high blood pressure, low high-density lipoprotein cholesterol (HDL-C) levels, or elevated triglycerides.^[1][2] Universal screening irrespective of the presence of risk factors is recommended for adults at least 35 years old. If initial screening results meet the criteria for prediabetes, it is recommended to repeat screenings yearly. If the results are normal, it is recommended to repeat screenings at least every three years, or sooner if symptoms of diabetes (e.g., excessive thirst) or other risk factors (e.g., hypertension) develop. ^[1]
