Symptoms of Prediabetes

What are the Symptoms of Prediabetes?

Although most people with prediabetes have no symptoms at all, symptoms of diabetes may include:
  • Increased thirst
  • Frequent urination
  • Fatigue
  • Blurred vision
Darkened areas of skin, a condition called acanthosis nigricans, is one of the few signs suggesting you are at risk for diabetes. Common areas that may be affected include the neck, armpits, elbows, knees and knuckles.

The doctor can test your blood to find out if your blood glucose levels are higher than normal. If you are 45 years old or older, your doctor may recommend that you be tested for pre-diabetes, especially if you are overweight.

Who Should be Tested for Prediabetes?

Consult your doctor if you're concerned about diabetes or if you notice any type 2 diabetes signs or symptoms — increased thirst and frequent urination, fatigue, and blurred vision.

Being overweight is a key contributor, along with inactivity, to prediabetes. If your body mass index (BMI) is higher than 25, you are overweight. BMI is a measure of your weight relative to your height. If you’re not sure if you are overweight, ask your doctor.

Even if you are younger than 45, consider getting tested for prediabetes if you are overweight and
  • are physically inactive
  • have a parent, brother, or sister with diabetes
  • have high blood pressure or high cholesterol—blood fat
  • have abnormal levels of High-density lipoprotein (HDL) , or good, cholesterol or triglycerides—another type of blood fat
  • had gestational diabetes—diabetes that develops only during pregnancy—or gave birth to a baby weighing more than 9 pounds
  • are African American, Alaska Native, American Indian, Asian American, Hispanic/Latino, or Pacific Islander American
  • have polycystic ovary syndrome, also called PCOS
  • have a dark, velvety rash around your neck or armpits
  • have blood vessel problems affecting your heart, brain, or legs
If your test results are normal, you should be retested in 3 years. If you have prediabetes, ask your doctor if you should be tested again in 1 year.
