Do my fatigue, thirst, and blurry vision mean diabetes?

Question

Hello doctor,

I am 27, and lately I keep wondering, Does fatigue at 27 that water cannot fix point toward undiagnosed diabetes? I feel thirsty almost the whole day and keep drinking bottles of water, but my mouth still feels dry after some time.

I started waking up three to four times at night just to urinate, and now even climbing stairs at work leaves me feeling drained. My mom says maybe I am just overworking, but last week I nearly

skipped lunch because I felt shaky and weird after a meeting. I checked my sugar once on my uncle’s machine after dinner, and it showed 198, though I do not know if that means anything serious. I also noticed blurry vision sometimes while driving home. Should I get tested urgently, or could this still be something less serious?

Kindly help.

Hello,

Welcome to icliniq.com.

I understand your concern.

I would say your symptoms are concerning for possible undiagnosed diabetes, and they deserve proper evaluation soon. Persistent thirst despite drinking large amounts of water, frequent urination, especially at night, fatigue, blurry vision, and episodes of shakiness are all symptoms we commonly see when blood glucose levels are elevated.

The reading of 198 milligrams per deciliter (mg/dL) after dinner is not diagnostic on its own because blood sugar naturally rises after eating, but in the setting of your symptoms, it is significant enough that I would not dismiss it. At 27, diabetes can absolutely occur, including both type 2 Diabetes and sometimes type 1 Diabetes in adults.

You should arrange testing with a doctor promptly, ideally within the next few days. The most useful tests would include:

Fasting blood glucose.
Hemoglobin A1c (HbA1c), which reflects your average sugar levels over the past two to three months.

A urine test and basic blood work may also be done to check hydration status, kidney function, and rule out other contributing conditions such as anemia or thyroid disease.

The blurry vision and exhaustion you describe can happen when glucose levels remain elevated for some time.

I hope you are satisfied with my answer. For further queries, you can consult me at iCliniq.

Thank you.
