Treat immediately, then call for help if you can't:

  • Blood sugar under 70 mg/dL — take 15 g fast-acting carbs (juice, glucose tabs)
  • Recheck in 15 minutes; repeat if still low
  • If unconscious or unable to swallow — call 911 or use glucagon
  • Frequent lows warrant a same-week medication review

What shaky, sweaty, and dizzy could be

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

Hypoglycemia / low blood sugar

Hypoglycemia / low blood sugar is one of the more common causes of shaky, sweaty, and dizzy. A provider can confirm with the right history, exam, or labs — and start treatment the same day when appropriate.

Type 2 diabetes

Type 2 diabetes is one of the more common causes of shaky, sweaty, and dizzy. 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 shaky, sweaty, and dizzy.

  • Focused history: timing, triggers, severity, and prior treatments related to "shaky, sweaty, and dizzy"
  • Targeted physical exam of the involved system
  • Rule-in / rule-out workup for the most likely causes: Hypoglycemia / low blood sugar, Type 2 diabetes
  • Labs, imaging, or referral only when the answer will change management

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
