Short answer
Prediabetes usually has no clear symptoms. You can feel completely normal while your blood glucose is in the prediabetes range, which is why screening and blood tests matter. Symptoms such as increased thirst or urination can occur with diabetes, but symptoms alone cannot diagnose prediabetes or diabetes.
Does prediabetes usually cause symptoms?
No. CDC and NIDDK both note that prediabetes often has no noticeable symptoms. That is one reason many people do not know they have it until a blood test is done for screening or another reason.
Feeling well is useful information about how you feel today, but it does not tell you whether your A1C or fasting glucose is in the normal, prediabetes, or diabetes range.
If I feel normal, why does testing matter?
A blood test can identify elevated glucose before symptoms appear. Finding prediabetes gives you and your healthcare team an opportunity to discuss risk factors, follow-up testing, and sustainable lifestyle changes before type 2 diabetes develops.
What if I do have symptoms that sound like diabetes?
Some people with prediabetes may have symptoms similar to diabetes, and type 2 diabetes itself can also develop without obvious symptoms. If you have new or concerning symptoms, do not use an online symptom list to diagnose yourself. Ask a healthcare professional whether blood testing is appropriate.
Who should ask about screening?
Screening decisions depend on age, weight, family history, pregnancy history, activity level, medications, and other health factors. A clinician can help decide whether and when you should be tested.
