Severe Hypoglycemia: Recognizing a Diabetic Emergency and What to Do

Severe hypoglycemia, often referred to as a "diabetic emergency," is a critical condition characterized by extremely low blood sugar levels, typically below 70 mg/dL (3.9 mmol/L), leading to significant cognitive impairment or unconsciousness. This condition demands immediate intervention to prevent serious complications such as seizures, coma, or even death. It's imperative for individuals with diabetes, their families, and caregivers to recognize the signs, understand the causes, and know precisely what to do in such an emergency.

Understanding Hypoglycemia and Its Severity

Hypoglycemia occurs when the level of glucose (sugar) in the blood falls too low. Glucose is the primary source of energy for the body, and the brain is particularly dependent on a consistent supply. For individuals with diabetes, managing blood glucose levels is a delicate balancing act, often involving insulin or oral medications, diet, and physical activity. When this balance is disrupted, hypoglycemia can occur.

Severity Scale:

Mild Hypoglycemia: Symptoms include shakiness, sweating, hunger, and mild confusion. The individual is usually able to treat it themselves with a quick source of sugar.
Moderate Hypoglycemia: Symptoms worsen, and may include increased confusion, irritability, difficulty concentrating, and impaired coordination. Assistance may be needed.
Severe Hypoglycemia: The individual is unable to treat themselves due to confusion, disorientation, loss of consciousness, or seizures. This requires emergency assistance from others, often involving glucagon administration or an emergency medical response.

Understanding this severity scale allows for a more informed and effective response based on the situation at hand.

Causes of Severe Hypoglycemia

Identifying the underlying causes of severe hypoglycemia is essential for prevention and management. Several factors can contribute to this dangerous condition:

1. Excessive Insulin or Medication Dosage:

Mechanism: Taking too much insulin or certain oral diabetes medications (sulfonylureas) lowers blood glucose levels more than intended.
Real-world example: A patient accidentally administers double their usual insulin dose due to a misread syringe.

2. Missed or Delayed Meals:

Mechanism: Not eating enough carbohydrates to match the insulin dose or medication taken can lead to a drop in blood sugar.
Real-world example: A person with diabetes skips lunch and then engages in physical activity, causing their blood sugar to plummet.

3. Increased Physical Activity:

Mechanism: Exercise increases the body's demand for glucose. If the insulin dose is not adjusted accordingly, or if extra carbohydrates aren't consumed, hypoglycemia can occur.
Real-world example: A runner with diabetes forgets to reduce their insulin dose before a long run and experiences a severe hypoglycemic episode mid-race.

4. Alcohol Consumption:

Mechanism: Alcohol can impair the liver's ability to release glucose into the bloodstream, especially when consumed on an empty stomach.
Real-world example: A person with diabetes drinks alcohol without eating, leading to a significant drop in blood sugar several hours later.

5. Kidney or Liver Disease:

Mechanism: These conditions can affect how insulin and medications are processed by the body, increasing the risk of hypoglycemia.

6. Hormonal Deficiencies:

Mechanism: Conditions such as adrenal insufficiency or pituitary disorders can impact glucose regulation.

7. Infections or Illness:

Mechanism: Illnesses can disrupt normal eating patterns and alter insulin sensitivity, increasing the likelihood of hypoglycemia.

8. Medication Interactions:

Mechanism: Certain medications can interact with diabetes drugs, enhancing their hypoglycemic effects.

Recognizing the Signs and Symptoms of Severe Hypoglycemia

Early recognition of hypoglycemia is crucial to prevent progression to a severe state. It's important to note that symptoms can vary from person to person. Some common signs and symptoms include:

Confusion and Disorientation: Difficulty thinking clearly, confusion, or an inability to follow simple instructions.
Loss of Consciousness: Passing out or becoming unresponsive.
Seizures: Involuntary muscle contractions and loss of awareness.
Weakness and Dizziness: Feeling unsteady or unable to stand.
Sweating and Clammy Skin: Profuse sweating, even in a cool environment.
Rapid Heartbeat: An increased heart rate, often noticeable to the individual or someone observing them.
Behavioral Changes: Uncharacteristic irritability, agitation, or aggression.

| Symptom | Mild Hypoglycemia | Moderate Hypoglycemia | Severe Hypoglycemia | | -------------------- | ---------------------- | --------------------------------- | -------------------------------------------------- | | Cognitive Function | Slightly Impaired | Noticeably Impaired | Unable to think clearly, loss of consciousness | | Coordination | Normal | Clumsy, unsteady | Possible seizures | | Skin | Normal | Sweating, clammy | Sweating, clammy | | Behavior | Anxious, irritable | More pronounced behavioral changes | Unresponsive, potential for combative behavior | | Heart Rate | Slightly Elevated | Elevated | Significantly Elevated | | Self-Treatment Ability | Able to treat self | May need assistance | Unable to treat self |

What to Do During a Severe Hypoglycemic Episode

Responding quickly and appropriately is essential to managing a severe hypoglycemic event. Here’s a step-by-step guide:

1. Assess the Situation:

Confirm Unresponsiveness: Check if the person is conscious. Gently shake their shoulder and ask if they are okay.
Look for Medical Identification: Check for a medical ID bracelet, necklace, or card that indicates they have diabetes.

2. Call for Emergency Assistance:

Dial Emergency Services: Immediately call emergency services (911 in the US, 999 in the UK, 112 in Europe).
Provide Information: Give the dispatcher details about the situation: "I have someone who is unresponsive and has diabetes. I suspect severe hypoglycemia." Include your exact location.

3. Administer Glucagon (if available):

What is Glucagon? Glucagon is a hormone that stimulates the liver to release stored glucose into the bloodstream. It is available as an injectable medication and, more recently, as a nasal spray.
How to Administer Injectable Glucagon:
- Check the Expiration Date: Ensure the glucagon kit is not expired.
- Prepare the Injection: Follow the instructions on the kit. Typically, you will need to mix the powdered glucagon with the diluent (liquid) provided.
- Administer the Injection: Inject the solution into the thigh, upper arm, or buttock. You can inject through clothing if necessary.
How to Administer Nasal Glucagon:
- Remove the device from its packaging: Follow the instructions on the packaging.
- Insert the tip into one nostril: Press the plunger to deliver the dose. You do not need to inhale.
Note: Glucagon may not work if the person has depleted their glycogen stores (e.g., due to prolonged fasting or malnutrition).

4. Position the Person Safely:

Recovery Position: If the person is breathing but unconscious, place them in the recovery position to prevent choking if they vomit. This involves rolling them onto their side, with the top leg bent at the knee and the head tilted back slightly.

5. Do Not Give Food or Drink:

Aspiration Risk: Never try to force food or liquid into the mouth of an unconscious person, as this can lead to choking or aspiration pneumonia.

6. Monitor Breathing and Circulation:

CPR if Necessary: If the person stops breathing or does not have a pulse, begin CPR if you are trained to do so. Follow the instructions provided by the emergency dispatcher.

7. Provide Information to Emergency Responders:

Medical History: When emergency medical services (EMS) arrive, provide them with all available information about the person's diabetes, medications, and the circumstances leading to the hypoglycemic episode.

Table: Glucagon Administration Steps

| Step | Injectable Glucagon | Nasal Glucagon | | ---------------- | ----------------------------------------------------------------- | ------------------------------------------------------------- | | 1 | Check expiration date on the kit. | Remove the device from its packaging. | | 2 | Prepare the injection: mix powder with diluent (follow instructions). | No preparation needed. | | 3 | Inject into thigh, upper arm, or buttock (can inject through clothing). | Insert tip into one nostril and press the plunger to deliver. | | 4 | Monitor for improvement. | Monitor for improvement. | | Important Note | Seek immediate medical attention even after glucagon is administered. | Seek immediate medical attention even after glucagon is administered. |
