What do I do when a diabetic's blood sugar is low

 When a diabetic’s blood sugar is low (hypoglycemia), it’s important to act quickly and appropriately. Here’s a clear step-by-step guide:


🚨 Step-by-Step: What to Do for Low Blood Sugar

✅ 1. Recognize the Symptoms

Common signs include:

  • Shakiness or trembling

  • Sweating

  • Hunger

  • Irritability or mood changes

  • Dizziness or confusion

  • Weakness or fatigue

  • Rapid heartbeat

  • Headache

If blood sugar is below 70 mg/dL (3.9 mmol/L), it’s considered low.


✅ 2. Give Fast-Acting Sugar (15-15 Rule)

If the person is conscious and able to swallow:

Give 15 grams of fast-acting carbohydrates, such as:

  • 4 glucose tablets

  • 1/2 cup (4 oz) of fruit juice (like orange or apple)

  • 1/2 can of regular (non-diet) soda

  • 1 tablespoon of sugar or honey

  • 5–6 hard candies (like Life Savers)

🕒 Wait 15 minutes, then recheck blood sugar.

  • If it’s still below 70 mg/dL, repeat the 15g treatment.

  • If it’s above 70, give a snack with protein and carbs (like crackers with peanut butter) if the next meal is more than an hour away.


⚠️ 3. If the Person is Unconscious or Can't Swallow

DO NOT give food or drink.

  • Call emergency services immediately (911 or local emergency number).

  • If trained and available, administer a glucagon injection or nasal spray.

    • Many diabetics carry a glucagon emergency kit or Baqsimi (nasal glucagon).


📌 4. Stay With the Person

  • Monitor closely until they are alert and stable.

  • Once they recover, encourage them to discuss the event with their doctor to adjust their treatment plan if needed.
