Understanding the 'Rule of 15'
For mild to moderate hypoglycemia (blood sugar below 70 mg/dL), the universally recommended approach is the "Rule of 15". This simple, three-step process is designed to raise blood sugar levels without causing an overcorrection that leads to hyperglycemia. The steps are as follows:
- Consume a specific amount of fast-acting carbohydrates.
- Wait 15 minutes.
- Recheck blood sugar levels.
If the patient's blood sugar is still below 70 mg/dL after the initial 15-minute wait, the process is repeated. It is crucial to repeat this cycle of consuming the designated amount of carbs, waiting 15 minutes, and rechecking blood sugar until the level is back within the target range.
Examples of Fast-Acting Carbohydrates
- Fruit juice or regular soda (not diet).
- Glucose tablets.
- Sugar, honey, or corn syrup.
- Hard candies or jelly beans.
- Glucose gel.
It is vital to avoid fast-acting carbohydrate sources that also contain significant fat or protein, such as chocolate or milk, as these can slow down sugar absorption and delay recovery. Once blood sugar is stabilized, the patient should consume a balanced snack or meal containing longer-acting carbohydrates and protein to prevent another drop.
Comparison of Fast-Acting Carbohydrate Sources
| Carbohydrate Source | Considerations for Serving Size | Pros | Cons |
|---|---|---|---|
| Glucose Tablets | Follow product instructions for the appropriate amount. | Pre-measured, fast-acting, easy to carry, and reliable. | Some find the taste unpleasant; can be expensive. |
| Fruit Juice/Regular Soda | A typical serving is often used. | Readily available and palatable; works quickly. | Requires accurate measurement; may be tempting to drink more than needed. |
| Hard Candy | The amount needed varies by candy type. | Convenient to carry; can be found easily. | Varies by candy type, so counting can be inaccurate. |
| Honey/Sugar | A standard measure is often used. | Common household item; effective when dissolved. | Can be messy; requires mixing and a spoon for accurate measurement. |
| Glucose Gel | Usually comes in pre-measured tubes. | Pre-measured, portable, and very fast-acting. | Can be more expensive; may not be as readily available. |
Management of Severe Hypoglycemia
Severe hypoglycemia is a medical emergency and cannot be treated with the Rule of 15 alone, especially if the patient is unconscious or disoriented. If a patient is unable to swallow safely, do not attempt to give them food or drink, as this can cause choking. The correct action is to administer a glucagon injection or nasal spray if available and trained to do so. Glucagon is a hormone that prompts the liver to release stored glucose, raising blood sugar levels. After administering glucagon, call for emergency medical help immediately.
Important Considerations
Patient-specific factors, such as age and weight, can influence treatment. For example, children may require different amounts of carbohydrates. Individualized treatment plans are sometimes necessary for people using insulin pumps or with recurring hypoglycemia. Long-term prevention of hypoglycemia involves working with a healthcare provider to adjust diet, medication timing, and exercise habits. Regularly monitoring blood sugar is key to catching lows early. Patients who experience frequent or severe episodes of hypoglycemia should consult their healthcare team to adjust their management plan. This collaborative approach helps identify underlying causes and ensures ongoing stability.
Conclusion
Treating a conscious hypoglycemic patient correctly requires following the "Rule of 15": consuming a specific amount of fast-acting carbohydrates, waiting 15 minutes, and rechecking blood sugar levels until they return to normal. For severe cases, especially if the patient is unconscious, the use of emergency glucagon and immediate medical attention is necessary. Understanding the proper carbohydrate sources and their appropriate serving sizes is a crucial part of effective diabetes management and ensures patient safety during a hypoglycemic episode. Prompt action and a clear understanding of these guidelines can make a significant difference in preventing complications.

Key Takeaways
- Rule of 15: For mild to moderate hypoglycemia, consume the recommended amount of fast-acting carbs, wait 15 minutes, and recheck blood sugar.
- Fast-Acting Carbs: Good options include glucose tablets, fruit juice, regular soda, or honey.
- Avoid High-Fat Carbs: Foods like chocolate or milk slow down sugar absorption and should be avoided during a low.
- Severe Hypoglycemia: If a patient is unconscious, do not give food. Administer emergency glucagon and call for immediate medical help.
- Stabilize After Treatment: Once blood sugar is stable, eat a balanced meal or snack to prevent a subsequent drop.
- Individualized Plans: Treatment may need adjustment based on individual factors like age or type of diabetes management.
- Preventative Measures: Regular blood sugar monitoring and a balanced management plan can help prevent future episodes.
