| Target blood glucose | Above 70 mg/dL |
| Treatment dose | 15g fast-acting carbohydrates |
| Recheck time | 15 minutes after treatment |
| Glucose tablet carbs | 4g per tablet |
| Juice serving | 4 oz = ~15g carbs |
| Onset time (tablets) | ~10 minutes |
Key Takeaways
- Treat hypoglycemia immediately with 15g of fast-acting carbohydrates
- Recheck blood sugar after 15 minutes; repeat if still below 70 mg/dL
- Glucose tablets are the gold standard β precise, portable, fast
- Always carry a treatment option; never drive with untreated low blood sugar
What Is Hypoglycemia?
Hypoglycemia (low blood sugar) occurs when blood glucose drops below 70 mg/dL. Symptoms include shakiness, sweating, confusion, and rapid heartbeat. Severe cases can cause unconsciousness and require emergency intervention.
The 15-15 Rule
The standard protocol endorsed by the American Diabetes Association: consume 15 grams of fast-acting carbohydrates, wait 15 minutes, then recheck. If blood sugar remains below 70 mg/dL, repeat the process.
Fast-Acting Treatment Options Compared
| Treatment | Carbs | Onset | Portability |
|---|---|---|---|
| Glucose tablets | 4g each | ~10 min | Excellent |
| Glucose gel | 15g/tube | ~10 min | Excellent |
| Orange juice (4oz) | 15g | ~15 min | Poor |
| Regular soda (4oz) | 13g | ~15 min | Poor |
| Hard candy (3-4 pcs) | ~15g | ~15 min | Good |
| Honey (1 tbsp) | 17g | ~15 min | Moderate |
Best Options by Situation
At Home
Keep glucose tablets or juice in an accessible location. MDS Diabetes stocks glucose tablets and emergency gel packs ideal for bedside or kitchen storage.
On the Go
Glucose tablets are the top choice β pre-measured, non-perishable, and pocket-sized. Avoid chocolate or high-fat foods, which slow glucose absorption significantly.
Severe Hypoglycemia (Unconscious Patient)
Never give food or liquid to an unconscious person. Use glucagon injection kits or nasal glucagon. Call 911 immediately. Caregivers should always have a glucagon emergency kit on hand.
What NOT to Use
- Diet sodas β contain no sugar
- Chocolate or peanut butter β fat slows absorption
- Protein bars β insufficient fast carbs
- Fruit with high fiber β slows glucose release
After Treatment
Once blood sugar returns above 70 mg/dL, eat a small snack containing protein and complex carbs (e.g., crackers with peanut butter) to prevent rebound hypoglycemia. Log the episode and review with your healthcare provider.
Emergency Preparedness Checklist
- Glucose tablets (carry 3-4 doses minimum)
- Glucagon kit at home and workplace
- Medical ID bracelet
- Emergency contact list
- Blood glucose meter with extra strips
