Understanding Hypoglycemia: What It Is and Why It Happens

Hypoglycemia occurs when your blood glucose level falls below a healthy range, typically below 70 mg/dL (3.9 mmol/L). It’s most common in people with diabetes, especially those taking insulin or certain oral medications, but it can also affect individuals without diabetes, though less frequently.

Diabetes Medications: Taking too much insulin or certain oral diabetes medications.
Skipping Meals: Not eating enough or missing meals can lead to a drop in blood sugar.
Excessive Exercise: Physical activity can lower blood sugar, especially if you haven't eaten enough beforehand.
Alcohol Consumption: Alcohol can interfere with the liver's ability to release glucose.
Certain Medical Conditions: Some medical conditions, such as kidney or liver disease, can contribute to hypoglycemia.
Reactive Hypoglycemia: This occurs a few hours after eating a normal meal and is thought to be related to an exaggerated insulin response.

Recognizing the Signs: Early vs. Severe Symptoms

The "Rule of 15": Treating Mild Hypoglycemia

The "Rule of 15" is a simple, effective method for treating mild hypoglycemia. Here's how it works:

Check Your Blood Sugar: If possible, confirm your blood sugar is below 70 mg/dL (3.9 mmol/L).
Consume 15 Grams of Fast-Acting Carbohydrates: Examples include:
- 4 ounces (1/2 cup) of juice or regular soda (not diet)
- 1 tablespoon of honey or sugar
- Glucose tablets (follow package instructions)
- Hard candies (about 3-4)
Wait 15 Minutes: Allow the carbohydrates to be absorbed into your bloodstream.
Recheck Your Blood Sugar: After 15 minutes, check your blood sugar again.
Repeat if Necessary: If your blood sugar is still below 70 mg/dL (3.9 mmol/L), repeat steps 1-4.

Important: After your blood sugar has returned to a safe range, eat a snack or meal containing protein and carbohydrates to help stabilize your blood sugar and prevent another drop.
