Seek urgent care or the ER if you have:

  • Symptoms that are sudden, severe, or rapidly worsening
  • High fever (over 103°F / 39.4°C) that doesn't respond to treatment
  • Chest pain, trouble breathing, fainting, or confusion
  • Signs of dehydration — dizziness, dark urine, unable to keep fluids down
  • Symptoms in someone who is pregnant, immunocompromised, or over 65

What diabetes symptoms could be

The most common causes a clinician considers. This isn't a diagnosis — it's the differential a provider works through with you.

Type 2 diabetes

Type 2 diabetes is one of the more common causes of diabetes symptoms. A provider can confirm with the right history, exam, or labs — and start treatment the same day when appropriate.

Prediabetes

Prediabetes is one of the more common causes of diabetes symptoms. A provider can confirm with the right history, exam, or labs — and start treatment the same day when appropriate.

Frequent urination

Frequent urination is one of the more common causes of diabetes symptoms. A provider can confirm with the right history, exam, or labs — and start treatment the same day when appropriate.

Typical workup

What a clinician usually orders or asks about when someone presents with diabetes symptoms.

  • Fasting glucose or random glucose, plus hemoglobin A1c
  • Lipid panel and comprehensive metabolic panel (kidney and liver function)
  • Urine microalbumin to screen for early kidney involvement
  • TSH if fatigue is a leading symptom

When to see a clinician

  • Symptoms have lasted more than a few days without improving, or keep coming back
  • You're not sure if this needs antibiotics, prescription treatment, or watchful waiting
  • You have a chronic condition (diabetes, heart disease, immunocompromised) that raises the stakes
  • You want a same-day plan without a trip to urgent care
