Often, prediabetes has no signs or symptoms.
One possible sign that you may be at risk of type 2 diabetes is darkened skin on certain parts of the body. This condition is called acanthosis nigricans. Common areas that may be affected include the neck, armpits, elbows, knees and knuckles.
Classic pre diabetes symptoms that suggest you’ve moved from prediabetes to type 2 diabetes include:
Increased thirst
Frequent urination
Fatigue
Blurred vision
When to see a doctor
Consult your doctor if you’re concerned about pre diabetic symptoms or if you notice any type 2 diabetes signs or symptoms — increased thirst and frequent urination, fatigue, and blurred vision.
Ask your doctor about blood glucose screening if you have any risk factors for prediabetes, such as:
You’re overweight, with a body mass index above 25
You’re inactive
You’re age 45 or older
You have a family history of type 2 diabetes
You’re African-American, Hispanic, American Indian, Asian-American or a Pacific Islander
You developed gestational diabetes when you were pregnant or gave birth to a baby who weighed more than 9 pounds (4.1 kilograms)
You have polycystic ovary syndrome — a condition characterized by irregular menstrual periods, excess hair growth and obesity
You have high blood pressure
Your high-density lipoprotein (HDL) cholesterol is below 35 milligrams per deciliter.
