Hypoglycemia, commonly known as low blood sugar, can be a dangerous condition that requires immediate attention. For people with diabetes or those on specific medications, hypoglycemia can occur when blood sugar drops below normal levels. This can lead to symptoms such as shakiness, confusion, sweating, and even loss of consciousness. Knowing how to recognize and treat a hypoglycemia attack is essential for both individuals affected and their caregivers. In this article, we’ll discuss what to do in the event of a hypoglycemia attack, the causes of low blood sugar, and how to prevent it from happening.
Understanding Hypoglycemia
What Is Hypoglycemia?
Hypoglycemia is defined as having a blood glucose level that is lower than normal. In most cases, hypoglycemia is defined by blood sugar levels below 70 mg/dL (3.9 mmol/L). However, individual targets may vary depending on personal health conditions, medications, and doctor recommendations.
Causes of Hypoglycemia
Hypoglycemia can be triggered by several factors, including:
Medications: People with diabetes often use insulin or other medications to control blood sugar. If too much insulin is administered, or if certain medications are taken without sufficient food intake, blood sugar can drop dangerously low.
Skipping Meals: Going for extended periods without eating can lead to a drop in blood sugar levels, especially if you are on medications like insulin or sulfonylureas, which increase insulin production.
Excessive Physical Activity: Engaging in vigorous exercise without adjusting food intake or medication can cause blood sugar to plummet.
Alcohol Consumption: Alcohol, particularly when consumed on an empty stomach, can interfere with the liver’s ability to release glucose into the bloodstream, resulting in hypoglycemia.
Medical Conditions: Certain medical conditions, such as adrenal or pituitary gland disorders, liver disease, or pancreatic tumors (insulinoma), can also cause low blood sugar.
Symptoms of Hypoglycemia
Recognizing the early symptoms of hypoglycemia is crucial for preventing severe complications. Common symptoms include:
- Shakiness
- Sweating
- Irritability
- Confusion or difficulty concentrating
- Weakness
- Dizziness
- Blurred vision
- Fast heartbeat (palpitations)
- Headache
- Slurred speech
Severe hypoglycemia can lead to:
- Loss of consciousness
- Seizures
- Coma
Immediate action is needed if severe symptoms occur.
What to Do for a Hypoglycemia Attack
1. Recognize the Symptoms Early
The first step in managing a hypoglycemia attack is to recognize the signs. As soon as symptoms like shakiness, sweating, or confusion begin, it’s important to act quickly.
2. Check Blood Sugar Levels
If possible, check your blood sugar level with a glucometer. This will give you a clear idea of how low your blood sugar is and help guide your treatment plan. If your blood sugar is below 70 mg/dL (3.9 mmol/L), you need to take immediate action to raise it.
3. Follow the “15-15 Rule”
The “15-15 Rule” is a commonly recommended strategy for treating mild to moderate hypoglycemia. This involves consuming 15 grams of fast-acting carbohydrates and then waiting 15 minutes to recheck your blood sugar. If your blood sugar is still below 70 mg/dL after 15 minutes, repeat the process. Here’s how to apply the 15-15 rule:
Foods Containing 15 Grams of Fast-Acting Carbohydrates:
- 4 glucose tablets
- 1 tube of glucose gel
- 1/2 cup (120 mL) of regular (non-diet) soda
- 1 tablespoon (15 grams) of sugar, honey, or corn syrup
- 1/2 cup (120 mL) of fruit juice
- 6 to 7 hard candies
4. Avoid Fatty Foods
While it may be tempting to eat a candy bar or a pastry during a hypoglycemia attack, avoid high-fat foods such as chocolate or ice cream. These foods can slow down the absorption of glucose and may delay the recovery process. Instead, opt for fast-acting carbohydrates, as listed above.
5. Monitor Symptoms
After consuming carbohydrates, it’s crucial to monitor how your body responds. Check your blood sugar after 15 minutes and assess your symptoms. If your blood sugar remains low or if symptoms persist, take another 15 grams of fast-acting carbohydrates. Repeat until blood sugar reaches a safe level, typically above 70 mg/dL.
6. Eat a Balanced Snack or Meal
Once your blood sugar returns to normal, it’s important to eat a balanced snack or meal to stabilize your blood sugar levels. This is particularly important if your next meal is more than an hour away. A balanced snack should include both carbohydrates and protein to provide long-lasting energy. Examples include:
- A peanut butter sandwich
- Cheese and crackers
- Yogurt with fruit
- A small apple with a handful of nuts
7. Seek Emergency Help for Severe Hypoglycemia
In cases of severe hypoglycemia where the person becomes unconscious, unable to swallow, or experiences seizures, emergency intervention is required. Here’s what to do:
Glucagon Injection: If you or a loved one has been prescribed a glucagon emergency kit, use it as directed. Glucagon is a hormone that stimulates the liver to release glucose into the bloodstream, raising blood sugar levels quickly. After administering the injection, contact emergency services immediately.
Call for Emergency Assistance: If glucagon is not available or the person does not respond to treatment, call for emergency medical assistance. Severe hypoglycemia can be life-threatening, and immediate help is needed.
Preventing Future Hypoglycemia Attacks
1. Adjust Medications
If hypoglycemia is a frequent occurrence, it’s important to work with your healthcare provider to adjust your diabetes medications. This may involve:
Lowering Insulin Doses: Reducing the amount of insulin you take may help prevent low blood sugar episodes.
Adjusting Other Medications: If you’re on medications that increase insulin production, your doctor may adjust the dosage or timing to prevent hypoglycemia.
2. Monitor Blood Sugar Regularly
Frequent blood sugar monitoring is key to preventing hypoglycemia. Aim to check your blood sugar at regular intervals, particularly before meals, after exercise, and before bedtime. Continuous glucose monitors (CGMs) can also provide real-time glucose readings and send alerts when blood sugar drops too low.
3. Eat Regularly
Eating regular, balanced meals can help maintain stable blood sugar levels throughout the day. Avoid skipping meals, especially if you’re on insulin or other blood sugar-lowering medications. Eating small, frequent meals may also help prevent dips in blood sugar.
4. Adjust Physical Activity
Exercise can affect blood sugar levels for hours after the activity. To prevent hypoglycemia, follow these guidelines:
Check Blood Sugar Before and After Exercise: This helps you understand how your body responds to physical activity.
Adjust Carbohydrate Intake: If you plan to engage in prolonged or intense exercise, you may need to eat extra carbohydrates or reduce your insulin dose. Consult your healthcare provider for specific recommendations.
5. Avoid Excessive Alcohol
Alcohol can interfere with the liver’s ability to release glucose into the bloodstream, leading to hypoglycemia. If you choose to drink alcohol, do so with food, and monitor your blood sugar closely afterward. Limit alcohol intake, particularly if you are at risk of hypoglycemia.
6. Carry Emergency Supplies
Always be prepared for a hypoglycemia attack by carrying emergency supplies with you. This can include:
Glucose Tablets or Gel: These are easy to carry and provide a fast source of sugar.
Snacks: Carry snacks like crackers or a granola bar to prevent blood sugar dips when meals are delayed.
Medical ID: Wearing a medical alert bracelet or carrying a card in your wallet can inform others of your condition in case of an emergency.
7. Educate Loved Ones
Make sure that your family, friends, and coworkers are aware of your condition and know what to do in case of a hypoglycemia attack. Educating them on how to recognize the symptoms and administer glucagon (if needed) can be life-saving.

Conclusion
Hypoglycemia attacks require prompt action to prevent serious health consequences. Recognizing the symptoms early, using the “15-15 rule,” and having a solid plan in place are essential for managing low blood sugar effectively. Beyond immediate treatment, taking steps to prevent future attacks through medication adjustments, regular blood sugar monitoring, and lifestyle changes can help maintain stable blood sugar levels and reduce the risk of hypoglycemia. If you experience frequent or severe hypoglycemia, consult your healthcare provider to develop a tailored treatment and prevention plan that works for you.
