Severe Hypoglycemia: A Guide to Emergency Treatment
Severe hypoglycemia, or dangerously low blood sugar, is a critical medical emergency that requires immediate action. It's a condition where the glucose levels in your blood drop to a point where your brain doesn't have enough fuel to function correctly, leading to confusion, seizures, loss of consciousness, and, in rare cases, even death. This guide provides a comprehensive overview of severe hypoglycemia, focusing on its causes, symptoms, and, most importantly, step-by-step instructions for emergency treatment. Whether you are a person with diabetes, a family member, a caregiver, or a healthcare professional, understanding how to recognize and treat severe hypoglycemia can be life-saving.
Why Severe Hypoglycemia Matters
Understanding the importance of prompt action in severe hypoglycemia is crucial. Glucose is the primary energy source for the brain. When glucose levels fall too low, the brain's functions are impaired, leading to rapid deterioration. The ability to quickly recognize symptoms and administer appropriate treatment can prevent long-term complications and potentially save a life. For individuals with diabetes, severe hypoglycemia is not just a temporary inconvenience; it's a serious health threat that needs to be managed proactively.
Understanding the Causes and Symptoms of Severe Hypoglycemia
To effectively respond to severe hypoglycemia, it's vital to understand its common causes and recognize its diverse symptoms. This knowledge helps in quick identification and appropriate intervention.
Common Causes of Severe Hypoglycemia
Severe hypoglycemia can result from various factors, especially in individuals managing diabetes. The most frequent causes include:
-
Excessive Insulin Dosage: This is the most common cause, occurring when a person injects or takes too much insulin relative to their food intake and activity level. This can happen due to dosage errors or changes in routine without adjusting insulin appropriately.
-
Missed or Delayed Meals: Skipping meals or delaying eating after taking insulin or oral diabetes medications can lead to a significant drop in blood glucose levels.
-
Increased Physical Activity: Exercise increases insulin sensitivity, causing glucose to be used up more quickly. Without proper carbohydrate adjustments, this can lead to hypoglycemia, especially after intense or prolonged physical activity.
-
Alcohol Consumption: Alcohol can interfere with the liver's ability to release glucose into the bloodstream. Consuming alcohol without food, particularly for those taking insulin or certain oral diabetes medications, can be particularly dangerous.
-
Certain Medications: Besides diabetes medications, some other drugs can interact and affect blood glucose levels. It's important to be aware of potential interactions when taking multiple medications.
-
Kidney or Liver Problems: The kidneys and liver play roles in glucose metabolism. Impaired function in these organs can affect glucose regulation and increase the risk of hypoglycemia.
-
Hormone Deficiencies: Certain hormonal disorders, like adrenal insufficiency, can affect glucose control and lead to hypoglycemia.
Recognizing the Symptoms of Severe Hypoglycemia
Symptoms of severe hypoglycemia can vary from person to person. It is important to recognize the signs early to prevent progression to a severe state. Symptoms are often classified into mild, moderate, and severe stages:
-
Mild Hypoglycemia:
- Shakiness or tremors
- Sweating
- Rapid heartbeat or palpitations
- Anxiety or nervousness
- Hunger
- Tingling or numbness around the mouth
-
Moderate Hypoglycemia:
- Confusion or difficulty concentrating
- Slurred speech
- Irritability or sudden mood changes
- Dizziness or lightheadedness
- Blurred vision or visual disturbances
- Weakness
-
Severe Hypoglycemia:
- Loss of consciousness
- Seizures or convulsions
- Inability to swallow
- Unresponsiveness
- Coma
Example Scenario: Imagine a person with diabetes who injects their usual dose of insulin but then gets delayed and misses their lunch. As the insulin starts to work, their blood sugar levels drop. Initially, they might experience mild symptoms like shakiness and sweating. If they continue to delay eating, the symptoms can progress to confusion and slurred speech. If left untreated, this could lead to loss of consciousness and severe hypoglycemia, requiring emergency intervention.
| Symptom | Mild Hypoglycemia | Moderate Hypoglycemia | Severe Hypoglycemia | | ------------------------- | ------------------------------------- | --------------------------------------- | ---------------------------------------------- | | Physical Signs | Shakiness, Sweating, Rapid Heartbeat | Dizziness, Weakness | Loss of Consciousness, Seizures | | Cognitive Changes | Anxiety, Hunger | Confusion, Irritability, Slurred Speech | Unresponsiveness, Inability to Swallow | | Neurological Symptoms | Tingling around Mouth | Blurred Vision | Coma |
Step-by-Step Guide to Emergency Treatment of Severe Hypoglycemia
When someone experiences severe hypoglycemia, prompt and correct treatment is critical. Since the individual is usually unable to self-treat due to impaired consciousness or seizures, it falls to others to intervene.
Step 1: Assess the Situation
Before taking any action, quickly assess the situation to confirm severe hypoglycemia. Look for the symptoms mentioned above (loss of consciousness, seizures). If you are unsure if it is hypoglycemia, it's generally safer to treat for hypoglycemia than to do nothing.
Step 2: Do Not Attempt Oral Treatment if Unconscious
If the person is unconscious, having a seizure, or unable to swallow, do not attempt to give them food or liquids by mouth. This could cause choking or aspiration, which can be life-threatening.
Step 3: Administer Glucagon
Glucagon is a hormone that stimulates the liver to release stored glucose into the bloodstream. It is available as an injectable medication designed for emergency use.
-
Locate the Glucagon Kit: Glucagon kits are usually prescribed to people at risk of severe hypoglycemia. Familiarize yourself with the kit's location if you are a family member, caregiver, or close contact of someone with diabetes.
-
Prepare the Injection: Follow the instructions provided in the glucagon kit. Typically, this involves mixing the powdered glucagon with the diluent provided in the syringe.

-
Administer the Injection: Inject the glucagon into the thigh, arm, or buttock. You can inject through clothing if necessary.
-
Dosage:
- Adults: Usually, a full dose (1 mg) is administered.
- Children: The dosage depends on the child’s weight. Follow the instructions in the kit or the prescribing physician’s advice. Typically, half the adult dose (0.5 mg) is given to children under 6 years or weighing less than 55 pounds.
Step 4: Call for Emergency Medical Assistance
Immediately after administering glucagon, call your local emergency number (e.g., 911 in the US) to request medical assistance. Provide them with as much information as possible:
- The person’s condition (unconscious, having seizures, etc.)
- That you suspect severe hypoglycemia
- That you have administered glucagon
- The location
Step 5: Monitor the Person
After administering glucagon, closely monitor the person's condition. It may take 5-15 minutes for them to regain consciousness.

- If the person regains consciousness: Once they are fully awake and able to swallow, give them a source of fast-acting carbohydrates, such as:
- Fruit juice
- Regular (non-diet) soda
- Glucose tablets or gel
- Follow this with a longer-acting carbohydrate source like crackers or a sandwich to stabilize blood sugar levels.
- If the person does not regain consciousness after 15 minutes: Follow instructions from the emergency responders. Do not administer a second dose of glucagon unless specifically instructed by medical professionals.
Step 6: Provide Information to Emergency Responders
When the emergency medical team arrives, provide them with all relevant information, including:
- That the person has diabetes (if known)
- The events leading up to the incident
- That you administered glucagon and the time it was given
- Any other medications the person takes
Step 7: Post-Emergency Care
After the immediate emergency, it's crucial to investigate and understand why the severe hypoglycemia occurred. This may involve:
- Consulting with a healthcare provider to review the person’s diabetes management plan
- Adjusting medication dosages
- Modifying meal timings
- Educating the person and their caregivers on preventing future episodes.
Example Scenario: Imagine you find a colleague at work unresponsive on the floor. You recognize that they have diabetes because they wear a medical ID bracelet. Following the steps above:
- You quickly assess that they are unconscious and cannot respond, suspecting severe hypoglycemia.
- You locate the glucagon kit in their desk drawer (knowing where it is because they informed you).
- You administer the glucagon injection into their thigh according to the kit's instructions.
- You immediately call 911, reporting the situation and that you have administered glucagon.
- You monitor your colleague, and after about 10 minutes, they start to regain consciousness.
- Once fully awake and able to swallow, you give them a juice box you found in the office kitchen, followed by crackers.
- You inform the paramedics about the situation when they arrive, including the time of the glucagon injection and your colleague’s usual medications.
