Recognizing Severe Hypoglycemia: Symptoms and Emergency Actions
Severe hypoglycemia, also known as very low blood sugar, is a dangerous condition that can occur in people with diabetes. It happens when the level of glucose (sugar) in the blood drops to a point where the brain doesn't have enough fuel to function properly. Recognizing the symptoms of severe hypoglycemia and knowing how to take emergency actions is crucial, as it can prevent serious complications, including seizures, loss of consciousness, and even death. This article provides a detailed guide to understanding severe hypoglycemia, recognizing its symptoms, and taking the necessary steps to respond effectively in an emergency.
What is Hypoglycemia and Why Does it Become Severe?
Hypoglycemia, commonly referred to as low blood sugar, occurs when the glucose level in the blood drops below 70 mg/dL. It’s a frequent complication for individuals managing diabetes, particularly those who use insulin or certain oral medications that increase insulin production. While mild to moderate hypoglycemia can often be managed by consuming fast-acting carbohydrates, severe hypoglycemia requires immediate intervention because the person is unable to treat themselves due to cognitive impairment or loss of consciousness.
The severity of hypoglycemia is primarily determined by the blood sugar level and the person's ability to function. Severe hypoglycemia is characterized by a blood glucose level that is so low that the individual requires assistance from another person to recover. This often involves administering glucagon or intravenous glucose to raise blood sugar levels quickly.
Common Causes of Hypoglycemia Becoming Severe:
- Excess Insulin: Taking too much insulin relative to food intake or activity level is a leading cause.
- Skipped or Delayed Meals: Not eating enough carbohydrates, or delaying meals, can cause blood sugar to drop.
- Increased Physical Activity: Exercise increases glucose uptake by muscles, which can lower blood sugar, especially if not properly planned for.
- Alcohol Consumption: Alcohol can interfere with the liver's ability to release glucose into the bloodstream.
- Kidney or Liver Problems: These conditions can impair the body’s ability to regulate blood sugar levels.
- Certain Medications: Some medications can interact with diabetes medications, increasing the risk of hypoglycemia.
Recognizing these risk factors is essential for both individuals with diabetes and their caregivers. Proper management and awareness can significantly reduce the likelihood of experiencing severe hypoglycemia.
Symptoms of Severe Hypoglycemia: Recognizing the Warning Signs
Recognizing the symptoms of severe hypoglycemia is critical for timely intervention. Symptoms can vary from person to person, and they may develop rapidly. Being aware of the early and late signs can help prevent a mild episode from escalating into a severe one.

Early Symptoms:
Early symptoms are the body's initial signals that blood sugar is dropping. These signs are typically mild and can be easily addressed by consuming fast-acting carbohydrates.
- Shakiness or Trembling: Feeling shaky or tremulous, as if your body is vibrating, is a common early indicator.
- Sweating: Unexplained sweating, particularly when not physically active or in a warm environment.
- Dizziness or Lightheadedness: Feeling unsteady or like the room is spinning.
- Hunger: An intense feeling of hunger, even if you've recently eaten.
- Irritability or Anxiety: Feeling unusually anxious, nervous, or easily irritated.
- Rapid Heartbeat: A noticeable increase in heart rate, sometimes described as palpitations.
- Pale Skin: Loss of color in the skin, especially noticeable on the face.
Late and Severe Symptoms:
Late-stage symptoms indicate that the brain is not receiving enough glucose, leading to more severe neurological effects. These symptoms require immediate action, as they indicate the individual is unable to self-treat and needs assistance.
- Confusion: Difficulty thinking clearly, disorientation, and an inability to focus.
- Difficulty Speaking: Slurred speech or trouble finding the right words.
- Blurred Vision or Double Vision: Visual disturbances indicating reduced brain function.
- Seizures: Uncontrolled muscle contractions and loss of awareness.
- Loss of Consciousness: Unresponsiveness and inability to wake up.
- Uncoordination: Difficulty with motor skills, such as walking or grabbing objects.
- Behavioral Changes: Unusual or erratic behavior, such as aggression or mood swings, that are out of character.

It’s essential for individuals at risk of hypoglycemia and their caregivers to recognize these symptoms. Educating family members, friends, and coworkers about the signs of severe hypoglycemia can ensure a quick and effective response during an emergency. Additionally, wearing a medical identification bracelet or carrying a card can alert first responders to the condition if the individual is unable to communicate.
Emergency Actions: Responding to Severe Hypoglycemia
When severe hypoglycemia occurs, prompt and appropriate action is crucial to prevent serious complications. The primary goal is to raise the person’s blood sugar level quickly to restore normal brain function. Here are the steps to take when responding to severe hypoglycemia:
1. Confirm Unresponsiveness and Check for Medical ID:
- If the person is unresponsive, try to gently rouse them by speaking loudly or shaking them gently.
- Check for a medical identification bracelet, necklace, or card indicating they have diabetes. This will confirm that hypoglycemia is a potential cause of their condition.
2. Do Not Give Food or Drink if Unconscious:
- Never attempt to give food or liquid to an unconscious person. This can cause choking or aspiration.
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 or a nasal spray.

If Glucagon is Available:
- Follow the instructions provided with the glucagon kit to prepare and administer the injection or nasal spray.
- Inject glucagon into the thigh, arm, or buttock, or administer the nasal spray into one nostril.
- After administering glucagon, turn the person on their side in the recovery position to prevent choking if they vomit.
-
If Glucagon is Not Available:
- Call emergency services immediately.
4. Call for Emergency Medical Assistance:
- Call your local emergency number (e.g., 911 in the United States, 112 in Europe, 000 in Australia) immediately.
- Provide the operator with as much information as possible, including that the person is unconscious and may be experiencing severe hypoglycemia.
- Follow any instructions provided by the emergency dispatcher.
5. Monitor and Provide Support:
- After administering glucagon, monitor the person's condition closely.
- It may take 10-15 minutes for the glucagon to raise blood sugar levels and for the person to regain consciousness.
- If the person regains consciousness, give them a fast-acting source of glucose, such as fruit juice, regular soda, or glucose tablets, followed by a longer-acting carbohydrate snack, such as crackers with peanut butter.
6. Document the Event:
- After the emergency is over, document the details of the event, including the symptoms observed, actions taken, and the person's response.
- Share this information with the person's healthcare provider to adjust their diabetes management plan as needed.
