Severe Hypoglycemia: Warning Signs and Emergency Treatment
Severe hypoglycemia, a critical complication of diabetes, occurs when blood glucose levels drop to dangerously low levels, often requiring assistance from another person for treatment. Understanding the warning signs, risk factors, and having a well-defined emergency treatment plan is crucial for individuals with diabetes and their caregivers. This article provides an in-depth look at severe hypoglycemia, covering early warning signs, emergency treatment protocols, preventive strategies, and long-term management.
Understanding Hypoglycemia and its Severity
Hypoglycemia, commonly known as low blood sugar, happens when the glucose level in your blood drops below what is healthy for you. For many people with diabetes, this means a blood sugar level less than 70 mg/dL (3.9 mmol/L). While mild to moderate hypoglycemia can often be managed independently, severe hypoglycemia can lead to significant health risks, including seizures, loss of consciousness, and even death.

Why is Glucose Important? Glucose is the primary source of energy for the body, especially the brain. Without enough glucose, the brain cannot function properly, leading to a range of symptoms.
Severity Levels: - Mild Hypoglycemia: Recognizable symptoms like shakiness or sweating, manageable with quick-acting carbohydrates. - Moderate Hypoglycemia: More pronounced symptoms like confusion or difficulty concentrating, requiring carbohydrate intake and possibly assistance. - Severe Hypoglycemia: Characterized by an inability to self-treat due to confusion, unconsciousness, seizures, or other neurological impairments, necessitating external help.
| Level | Blood Glucose (mg/dL) | Symptoms | Treatment | |----------------|-----------------------|-----------------------------------------------------|---------------------------------------------------------------------------------| | Mild | 60-70 | Shakiness, sweating, hunger, irritability | 15-20 grams of fast-acting carbohydrates | | Moderate | 40-60 | Confusion, difficulty concentrating, slurred speech | 15-20 grams of fast-acting carbohydrates; assistance may be needed | | Severe | <40 | Unconsciousness, seizures, inability to self-treat | Glucagon injection or intravenous glucose by emergency responders or healthcare professionals |
Recognizing the Warning Signs of Severe Hypoglycemia
Early recognition of hypoglycemia is critical in preventing it from escalating into a severe episode. While initial symptoms can vary from person to person, understanding the common warning signs can enable timely intervention.
Early Warning Signs:
- Shakiness and Trembling: One of the first noticeable signs.
- Sweating: Often accompanied by a feeling of clamminess.
- Dizziness: Lightheadedness or a sensation of spinning.
- Hunger: An intense craving for food, even after recently eating.
- Irritability or Mood Changes: Unexplained feelings of anxiety, frustration, or sudden mood swings.
- Confusion or Difficulty Concentrating: Trouble focusing or making simple decisions.
- Rapid Heartbeat: A sensation of the heart racing or pounding.
- Pale Skin: Noticeable paleness in the face.
Signs Progressing to Severe Hypoglycemia:
- Loss of Coordination: Difficulty walking or performing simple tasks.
- Slurred Speech: Inability to speak clearly.
- Vision Changes: Blurred or double vision.
- Seizures: Uncontrolled muscle spasms or convulsions.
- Unconsciousness: Inability to respond to stimuli, loss of awareness.
Nocturnal Hypoglycemia
Hypoglycemia that occurs during sleep can be particularly dangerous because individuals are unaware of the symptoms. Can You Feel When Your Blood Sugar Is High The Telltale Signs
Signs of Nocturnal Hypoglycemia:
- Nightmares or Restless Sleep: Unusual and disturbing dreams.
- Sweating During Sleep: Waking up with damp sheets or pajamas.
- Headache Upon Waking: Persistent headache in the morning.
- Feeling Unusually Tired: Despite getting adequate sleep.
Immediate Treatment for Severe Hypoglycemia
When severe hypoglycemia strikes, time is of the essence. Immediate action can prevent serious complications. Treatment primarily involves raising blood glucose levels using either a glucagon injection or intravenous glucose, administered by healthcare professionals.
Glucagon Injections
Glucagon is a hormone that stimulates the liver to release stored glucose into the bloodstream. It’s typically administered via injection and is a critical tool for treating severe hypoglycemia outside of a hospital setting.
When to Use Glucagon:
- The person is unconscious or unable to swallow.
- They are having a seizure.
- They are too confused to eat or drink.
Steps for Administering Glucagon:

- Check the Expiration Date: Ensure the glucagon kit hasn’t expired.
- Prepare the Injection:
- Locate the glucagon kit and remove the cap from the syringe and the vial containing the powdered glucagon.
- Inject the liquid from the syringe into the vial.
- Gently roll (do not shake) the vial to mix until the glucagon is completely dissolved.
- Withdraw the dissolved glucagon back into the syringe.
- Administer the Injection:
- Inject the glucagon into the thigh, buttock, or upper arm muscle.
- Hold the syringe steady while injecting to ensure the full dose is administered.
- Call for Emergency Help: Immediately call emergency services (911) after administering the glucagon.
Post-Injection Care:
- Turn the Person on Their Side: To prevent choking if they vomit.
- Monitor Their Breathing: Ensure they are breathing normally.
- Check Blood Glucose Levels: After they regain consciousness.
- Provide a Carbohydrate Snack: Once they can swallow, give them a snack like crackers or fruit juice to stabilize blood sugar.
Intravenous Glucose
In a hospital setting, healthcare professionals administer glucose directly into the bloodstream through an IV line. This method is faster and more precise than glucagon injections. Mastering Your Blood Sugar A Comprehensive Guide To Diabetes Control
When IV Glucose is Preferred:
- The person is already in a hospital or medical facility.
- Glucagon is unavailable or ineffective.
- There is a known contraindication for glucagon use.
Procedure:
- Establish IV Access: Insert an IV line into a vein.
- Administer Glucose Solution: Infuse a concentrated glucose solution (usually 50% dextrose) directly into the bloodstream.
- Monitor Blood Glucose Levels: Continuously monitor blood glucose levels to ensure they stabilize.
Important Considerations for Emergency Treatment
- Educate Family and Friends: Ensure that family members, caregivers, and close friends know how to recognize the signs of severe hypoglycemia and how to administer glucagon.
- Keep Glucagon Accessible: Always have a glucagon kit on hand at home, work, and when traveling. Check the expiration date regularly.
- Carry Identification: Wear a medical ID bracelet or carry a card indicating that you have diabetes and may experience hypoglycemia.
- Train Caregivers: Regularly review the proper glucagon administration technique with caregivers to ensure they are comfortable and competent.
Risk Factors for Severe Hypoglycemia
Several factors can increase the risk of developing severe hypoglycemia. Identifying and addressing these factors is essential for proactive management.
Common Risk Factors:
- Intensive Insulin Therapy: Tightly controlled insulin regimens increase the risk of hypoglycemia.
- Missed or Delayed Meals: Skipping meals or delaying carbohydrate intake can lead to low blood sugar.
- Increased Physical Activity: Exercise can lower blood glucose levels, particularly if not properly balanced with carbohydrate intake.
- Alcohol Consumption: Alcohol can impair the liver's ability to release glucose, leading to hypoglycemia, especially when consumed without food.
