What is Severe Hypoglycemia and How Do You Treat It?
Severe hypoglycemia, often referred to as insulin shock or severe low blood sugar, is a dangerous condition that occurs when blood glucose levels drop to a point where a person becomes mentally or physically incapacitated and requires assistance from another individual to recover. Unlike mild or moderate hypoglycemia, which a person can often manage on their own, severe hypoglycemia poses a significant risk and necessitates immediate intervention to prevent serious complications, including seizures, coma, and even death. This article will explore the causes, symptoms, and, most importantly, the treatment of severe hypoglycemia, providing essential information for individuals with diabetes, their families, and caregivers.
Understanding Hypoglycemia and Its Progression
To fully grasp the severity of severe hypoglycemia, it's essential to understand the spectrum of hypoglycemia.
Hypoglycemia is generally defined as a blood glucose level below 70 mg/dL (3.9 mmol/L). The symptoms can vary from person to person, but common signs include:
- Mild Hypoglycemia: Shaking, sweating, anxiety, dizziness, hunger, rapid heartbeat, blurred vision.
- Moderate Hypoglycemia: Confusion, irritability, difficulty concentrating, weakness, coordination problems.
Severe Hypoglycemia: Characterized by an inability to self-treat due to significant cognitive impairment, loss of consciousness, seizures, or coma. This stage requires external assistance, such as administration of glucagon or intravenous glucose by another person.
The progression from mild to severe hypoglycemia can be rapid, especially if the initial symptoms are ignored or go unnoticed. Several factors can contribute to a rapid drop in blood sugar levels, including:
- Excessive Insulin Dosage: Taking too much insulin relative to food intake or activity level.
- Missed or Delayed Meals: Insufficient carbohydrate intake to match insulin dosage.
- Strenuous Exercise: Increased glucose utilization during and after physical activity.
- Alcohol Consumption: Alcohol can interfere with the liver's ability to release glucose into the bloodstream.
- Certain Medications: Some drugs, such as sulfonylureas, can increase the risk of hypoglycemia.
- Kidney or Liver Disease: Impaired organ function can affect glucose metabolism.
| Stage of Hypoglycemia | Blood Glucose Level (mg/dL) | Common Symptoms | Self-Treatment Possible? | | :-------------------- | :-------------------------- | :------------------------------------------------ | :----------------------- | | Mild | Below 70 | Shaking, sweating, dizziness, hunger | Yes | | Moderate | Below 70 | Confusion, irritability, difficulty concentrating | Sometimes | | Severe | Below 70 | Loss of consciousness, seizures, coma | No |
Recognizing the Signs and Symptoms of Severe Hypoglycemia
Recognizing the signs of severe hypoglycemia is critical for timely intervention. Since the individual may be unable to communicate or react normally, caregivers and family members need to be vigilant. Key indicators include:
- Unconsciousness or Unresponsiveness: The person may be unable to be roused or respond to questions or commands.
- Seizures: Uncontrolled muscle contractions or convulsions.
- Confusion and Disorientation: Extreme confusion, difficulty understanding surroundings, or inability to recognize people.
- Inability to Swallow: Making it difficult to safely administer oral treatments.
- Pale or Clammy Skin: Indicating a drop in blood sugar levels.
- Erratic Behavior: Displaying unusual or aggressive behavior due to impaired brain function.
It's important to note that not all individuals experience the same symptoms, and the presentation of severe hypoglycemia can vary. If you suspect someone is experiencing severe hypoglycemia, it's crucial to act quickly and decisively.
Treating Severe Hypoglycemia: A Step-by-Step Guide
The treatment of severe hypoglycemia requires prompt action to restore blood glucose levels to a safe range. The two primary methods for treating severe hypoglycemia are glucagon administration and intravenous glucose administration. Simple Steps To Lower Your A1C And Control Blood Sugar
1. Glucagon Administration
Glucagon is a hormone that stimulates the liver to release stored glucose into the bloodstream, raising blood sugar levels. Glucagon is available as an injectable medication and, more recently, as a nasal spray. Here's how to administer glucagon effectively:
a. Confirm the Diagnosis: Ensure that the individual is unresponsive and shows signs of severe hypoglycemia.
b. Locate the Glucagon Kit: Most individuals at risk of severe hypoglycemia should have a glucagon emergency kit readily available.
c. Prepare the Injection (if using injectable glucagon):
- Remove the cap from the glucagon vial.
- Remove the cap from the syringe containing the diluent (sterile water).
- Inject the entire contents of the syringe into the glucagon vial.
- Gently roll (do not shake) the vial to dissolve the glucagon powder completely.
- Withdraw the prescribed dose of glucagon (usually 1 mg for adults and 0.5 mg for children) into the syringe.

d. Administer the Glucagon:
- Injection: Inject the glucagon into the thigh, buttock, or arm. It can be injected through clothing if necessary.
- Nasal Spray: Insert the tip of the device into one nostril and press the plunger to deliver the dose.
e. Call for Emergency Medical Assistance (911): Glucagon is a temporary solution and medical evaluation is still necessary.
f. Monitor the Person: After glucagon administration, monitor the person closely for improvement. It may take 10-15 minutes for the glucagon to raise blood sugar levels.
g. Once Conscious, Provide Food: Once the person regains consciousness and is able to swallow, provide them with a fast-acting source of glucose, such as fruit juice, glucose tablets, or a regular (non-diet) soda, followed by a longer-acting source of carbohydrates and protein, such as crackers with peanut butter or a sandwich.
Important Considerations for Glucagon Administration:
- Check Expiration Date: Ensure the glucagon kit is not expired. An expired kit may not be effective.
- Learn Proper Technique: Practice with a healthcare professional to learn the correct glucagon administration technique.
- Inform Others: Educate family members, caregivers, and close friends about how to recognize and treat severe hypoglycemia, including glucagon administration.
- Side Effects: Some common side effects of glucagon include nausea and vomiting. Be prepared for this possibility.
- Glucagon Nasal Spray: Is an easier alternative to administer, with no mixing or injection required.
2. Intravenous Glucose Administration
Intravenous (IV) glucose is a direct way to rapidly raise blood glucose levels. This method is typically administered by healthcare professionals in a hospital or emergency medical setting.
a. Call for Emergency Medical Assistance (911): If the individual is unresponsive and you are not a healthcare professional, the primary action is to call for emergency medical assistance. Paramedics or emergency medical technicians (EMTs) can initiate IV glucose administration. Managing Diabetes The Complete Guide To Your A1C And Glucose Levels
b. Medical Professionals will: Establish an IV line and administer a concentrated glucose solution (e.g., D50W – 50% dextrose in water) directly into the bloodstream.
c. Monitor Vital Signs: Closely monitor the individual's vital signs (heart rate, blood pressure, respiratory rate) and blood glucose levels throughout the treatment process. Creating The Perfect Meal Plan To Manage Type 2 Diabetes
d. Provide Ongoing Care: Continue to provide supportive care, including monitoring blood glucose levels and adjusting insulin dosages as needed, to prevent recurrence of hypoglycemia.

Prevention Strategies for Severe Hypoglycemia
While knowing how to treat severe hypoglycemia is essential, preventing it in the first place is paramount. The following strategies can help reduce the risk of severe hypoglycemic episodes:
- Regular Blood Glucose Monitoring: Consistently monitoring blood glucose levels using a glucose meter or continuous glucose monitoring (CGM) system allows individuals to identify and address low blood sugar trends early.
- Consistent Meal and Snack Timing: Eating meals and snacks at regular intervals helps maintain stable blood glucose levels. Skipping meals or delaying snacks can lead to hypoglycemia, especially for those taking insulin or sulfonylureas.
- Carbohydrate Counting: Learning to accurately estimate the carbohydrate content of meals and snacks can help individuals match their insulin dosage to their food intake.
- Adjusting Insulin Dosages: Work closely with a healthcare provider to adjust insulin dosages based on blood glucose levels, activity levels, and other factors.
- Exercising Safely: Adjust insulin dosages or carbohydrate intake before, during, and after exercise to prevent exercise-induced hypoglycemia. Monitor blood glucose levels more frequently during and after physical activity.
- Alcohol Awareness: Be aware that alcohol can increase the risk of hypoglycemia, especially when consumed on an empty stomach. Consume alcohol in moderation and with food.
- Medication Management: Understand how different medications can affect blood glucose levels and adjust medication dosages accordingly.
- Hypoglycemia Awareness Training: Attend educational programs and workshops to learn more about hypoglycemia, its symptoms, and treatment strategies.
- Wearing Medical Identification: Wearing a medical identification bracelet or necklace that indicates the person has diabetes can alert others to the possibility of hypoglycemia in case of an emergency.
- Continuous Glucose Monitoring (CGM): CGM devices track glucose levels in real-time and can alert users to impending hypoglycemia, allowing for proactive intervention.
- Insulin Pump Therapy: Insulin pumps deliver a continuous basal rate of insulin, which can be adjusted to meet individual needs and reduce the risk of hypoglycemia.
The Importance of Education and Preparedness
Living with diabetes requires ongoing education and preparedness to manage blood glucose levels effectively and prevent complications like severe hypoglycemia. Individuals with diabetes, their families, and caregivers should:
- Attend Diabetes Education Programs: Participate in comprehensive diabetes education programs to learn about self-management strategies, including blood glucose monitoring, insulin administration, carbohydrate counting, and hypoglycemia management.
- Develop a Hypoglycemia Action Plan: Create a written action plan that outlines the steps to take in case of hypoglycemia, including when to check blood glucose levels, what to eat or drink to raise blood sugar levels, and when to seek medical assistance.
- Keep Glucagon Readily Available: Always have a glucagon emergency kit readily available at home, at work, and when traveling. Check the expiration date regularly and replace it as needed.
- Educate Family and Friends: Educate family members, caregivers, and close friends about how to recognize and treat severe hypoglycemia, including glucagon administration.
- Carry Fast-Acting Glucose: Always carry a source of fast-acting glucose, such as glucose tablets, fruit juice, or hard candies, to treat mild to moderate hypoglycemia promptly.
- Stay Informed: Stay up-to-date on the latest advances in diabetes management, including new medications, technologies, and treatment guidelines.
