Severe Hypoglycemia: Recognizing a Diabetic Emergency and How to Act Fast

Hypoglycemia, often called low blood sugar, is a condition where the level of glucose in the blood drops below normal. While mild hypoglycemia can often be managed with a quick snack, severe hypoglycemia is a dangerous diabetic emergency that requires immediate intervention. This article will delve into recognizing severe hypoglycemia, its potential causes, the immediate steps to take, and the importance of prevention. We'll provide actionable information to help you respond effectively and potentially save a life.

What is Severe Hypoglycemia and Why is it a Diabetic Emergency?

Severe hypoglycemia is characterized by a dangerously low blood glucose level that results in impaired mental or physical function, requiring assistance from another person to treat. Unlike mild hypoglycemia, the affected individual is often unable to help themselves and might experience symptoms like confusion, seizures, or loss of consciousness.

Why is Severe Hypoglycemia an Emergency?

Brain Function: Glucose is the primary energy source for the brain. When glucose levels drop too low, the brain's ability to function is compromised. Prolonged lack of glucose can lead to irreversible brain damage or even death.
Seizures: Severe hypoglycemia can trigger seizures, which can be harmful and life-threatening.
Cardiovascular Stress: The body's response to low blood sugar includes the release of adrenaline, which can put extra stress on the heart. This can be particularly risky for individuals with existing heart conditions.
Loss of Consciousness: If untreated, severe hypoglycemia can lead to a loss of consciousness, increasing the risk of injury due to falls or accidents.

Typical Blood Sugar Levels

To understand hypoglycemia, it's crucial to know the normal blood sugar ranges:

| Category | Blood Sugar Level (mg/dL) | Blood Sugar Level (mmol/L) | | ------------------------------ | ------------------------- | -------------------------- | | Normal (Fasting) | 70-99 | 3.9-5.5 | | Normal (2 hours after eating) | Less than 140 | Less than 7.8 | | Hypoglycemia | Less than 70 | Less than 3.9 | | Severe Hypoglycemia (typically) | Below 40 | Below 2.2 |

Note: These values can vary slightly based on individual factors and specific guidelines from healthcare providers.

Recognizing Severe Hypoglycemia: Symptoms and Warning Signs

Early recognition of hypoglycemia can prevent it from escalating to a severe state. It's important to know the signs and symptoms associated with low blood sugar, and how they might present differently in different individuals.

Symptoms of Mild to Moderate Hypoglycemia:

Shakiness
Sweating
Dizziness or lightheadedness
Hunger
Irritability or anxiety
Confusion
Rapid heartbeat
Blurred vision
Weakness
Headache

Symptoms of Severe Hypoglycemia:

Inability to eat or drink
Confusion, disorientation, or irrational behavior
Slurred speech
Seizures or convulsions
Loss of consciousness

Important Note: Not everyone experiences the same symptoms of hypoglycemia, and some individuals may develop hypoglycemia unawareness, meaning they no longer experience the early warning signs. This can be particularly dangerous as it increases the risk of severe hypoglycemic episodes.

What Causes Severe Hypoglycemia?

Several factors can contribute to the development of severe hypoglycemia in individuals with diabetes:

Excessive Insulin or Diabetes Medication: Taking too much insulin or other medications that lower blood sugar is the most common cause of hypoglycemia. This can occur due to dosing errors, changes in medication needs, or miscalculation of carbohydrate intake.
Skipped or Delayed Meals: Failing to eat regularly, or delaying meals, can lead to a drop in blood sugar levels, especially when taking insulin or other glucose-lowering medications.
Intense Exercise: Physical activity can lower blood sugar levels, particularly if it is prolonged or strenuous. If the activity is not planned well or carbohydrates are not adjusted accordingly, hypoglycemia can occur.
Alcohol Consumption: Alcohol can interfere with the liver's ability to release glucose into the bloodstream, especially when consumed without food. This can result in significant drops in blood sugar levels.
Kidney or Liver Problems: Individuals with kidney or liver disease may be more susceptible to hypoglycemia due to impaired glucose metabolism and medication clearance.
Certain Medical Conditions: Conditions that affect the adrenal glands or pituitary gland can disrupt hormone regulation, potentially leading to hypoglycemia.
Insulin Resistance: Sometimes the body may not respond properly to insulin, leading to a drop in blood sugar.

How to Act Fast During a Severe Hypoglycemic Episode: Step-by-Step Guide

When someone is experiencing severe hypoglycemia, swift action is critical. Here's a detailed guide on how to respond effectively:

Step 1: Recognize the Situation

Identify the Symptoms: Look for the symptoms mentioned above, particularly confusion, loss of consciousness, or seizures.
Check Medical Identification: Look for a medical ID bracelet, necklace, or card indicating the person has diabetes.
Ask Others: If there are witnesses, ask if they know the person and their medical history.

Step 2: Do Not Give Anything by Mouth to an Unconscious Person

Risk of Choking: Giving food or liquid to an unconscious person can cause choking.
Need for Immediate Intervention: Unconscious individuals require interventions that bypass the digestive system, such as glucagon or intravenous glucose.

Step 3: Administer Glucagon (if Available)

What is Glucagon? Glucagon is a hormone that raises blood sugar levels by stimulating the liver to release stored glucose. It is available as an injectable medication.
How to Administer Glucagon:
1. Locate the Glucagon Kit: The glucagon kit usually contains a syringe and a vial of powdered glucagon.
2. Prepare the Injection: Follow the instructions provided with the glucagon kit, which typically involves mixing the powdered glucagon with the liquid in the syringe.
3. Administer the Injection: Inject the glucagon into the person's thigh, arm, or buttocks. You don't need to see their skin. The injection can be given through clothing if needed.
4. Stay with the Person: Turn the person onto their side (recovery position) to prevent choking if they vomit.
Important Considerations:
- Glucagon may take 10-15 minutes to work.
- Some people may experience nausea and vomiting after receiving glucagon.
- Glucagon is not effective if the person's glucose stores in the liver are depleted (e.g., after prolonged starvation or strenuous exercise).

Step 4: Call for Emergency Medical Assistance

Dial Emergency Services: Call your local emergency number (e.g., 911 in the US, 111 in the UK, 000 in Australia) immediately.
Provide Information: Tell the emergency operator that the person is unresponsive and suspected to have severe hypoglycemia due to diabetes.
Follow Instructions: Follow any instructions given by the emergency operator.

Step 5: Monitor the Person

Check for Breathing: Ensure the person is breathing adequately. If they are not breathing, start CPR if you are trained to do so.
Observe Symptoms: Continue to monitor the person's symptoms until emergency medical services arrive.

Step 6: Post-Emergency Care

Medical Evaluation: The person needs to be evaluated by a healthcare professional to determine the cause of the hypoglycemic episode and adjust their diabetes management plan.
Replenish Glucose Stores: Once the person is conscious and able to swallow, give them a quick-acting source of glucose, such as fruit juice, glucose tablets, or a sugary snack, followed by a longer-acting carbohydrate source (e.g., crackers, bread).
Review Diabetes Management: Work with the person and their healthcare team to review their diabetes management plan, including medication dosages, meal plans, and blood glucose monitoring practices.
Educate Caregivers: Educate family members, friends, and caregivers about the signs and symptoms of hypoglycemia, and how to administer glucagon if necessary.
