Severe Hypoglycemia: Warning Signs and What to Do Immediately

Severe hypoglycemia, or critically low blood sugar, is a dangerous condition that requires immediate attention. It occurs when the glucose level in your blood drops too low to fuel your body's functions, especially the brain. Recognizing the warning signs of hypoglycemia and knowing how to respond quickly can be life-saving. This article provides a comprehensive overview of severe hypoglycemia, its signs, causes, and immediate steps to take in case of an emergency.

What is Severe Hypoglycemia?

Hypoglycemia, in general, means low blood sugar. Severe hypoglycemia is when blood sugar drops so drastically that the person becomes confused, loses consciousness, has seizures, or needs assistance from someone else to recover. It’s a serious complication typically, but not exclusively, associated with diabetes and the medications used to manage it, particularly insulin. However, it can also occur in people without diabetes under certain circumstances. The threshold for diagnosing hypoglycemia can vary, but severe cases generally involve blood glucose levels below 70 mg/dL (3.9 mmol/L) combined with noticeable symptoms.

Causes of Severe Hypoglycemia

Understanding the causes of severe hypoglycemia is essential for prevention. Common causes include:

• Excessive Insulin Dosage: This is one of the most frequent causes in individuals with diabetes. An error in dosage, injecting too much insulin relative to food intake and activity levels, can trigger a rapid and significant drop in blood sugar.
• Skipping or Delaying Meals: When you take insulin or other glucose-lowering medications, missing meals can lead to an imbalance between the medication's effect and glucose availability. This can result in blood sugar levels falling dangerously low.
• Increased Physical Activity: Exercise consumes glucose. Without adjusting medication dosages or increasing carbohydrate intake, unplanned or vigorous physical activity can deplete blood sugar stores quickly, inducing hypoglycemia.
• Alcohol Consumption: Alcohol can impair the liver’s ability to release glucose into the bloodstream. It also affects your awareness of hypoglycemia symptoms, making it harder to take timely corrective action. Consuming alcohol on an empty stomach increases the risk.
• Kidney or Liver Disease: The kidneys and liver play crucial roles in glucose metabolism and hormone regulation. If these organs are compromised, it can lead to fluctuations in blood glucose levels and increase the risk of hypoglycemia.
• Certain Medications: Apart from diabetes medications, some other drugs can interact with glucose metabolism. Medications like quinine (used to treat malaria) and pentamidine (an antimicrobial) have been linked to causing hypoglycemia in rare cases.
• Hormone Deficiencies: Hormonal disorders like adrenal insufficiency (Addison's disease) or pituitary problems can disrupt the balance of hormones that regulate blood sugar levels, increasing the likelihood of hypoglycemia.
• Reactive Hypoglycemia: Also known as postprandial hypoglycemia, this occurs in people without diabetes usually within a few hours after eating a meal. It’s caused by an exaggerated release of insulin in response to the meal.

Recognizing the Warning Signs

Early recognition of hypoglycemia is crucial to preventing a severe episode. Common warning signs of hypoglycemia include:

• Shakiness or Trembling: A sudden and uncontrollable trembling is a telltale sign of hypoglycemia. Your body's nervous system reacts to the glucose shortage by triggering adrenaline release, which can cause tremors.
• Sweating: Similar to shakiness, sweating – especially cold sweats – often accompanies low blood sugar. This is also part of the adrenaline response to low glucose levels.
• Dizziness or Lightheadedness: Glucose fuels the brain. When glucose is insufficient, it can result in a feeling of dizziness or lightheadedness due to reduced energy supply to brain cells.
• Confusion or Difficulty Concentrating: The brain relies heavily on glucose for optimal cognitive function. Low glucose levels impair cognitive processes, leading to confusion, disorientation, and difficulty concentrating.
• Irritability or Mood Changes: Hypoglycemia can disrupt neurotransmitter function and affect mood regulation. Individuals may experience sudden and unexplained irritability, anxiety, or emotional lability.
• Rapid Heartbeat (Palpitations): As the body attempts to compensate for the glucose deficiency, the heart rate increases to pump blood faster and deliver what little glucose there is to critical organs.
• Blurred Vision: Reduced glucose affects eye function, leading to temporary vision changes, like blurred vision or double vision.
• Hunger: A sudden feeling of extreme hunger, even after eating recently, is another warning sign of hypoglycemia. Your body is craving glucose, and the hunger is a signal that your blood sugar has dipped too low.
• Headache: Some people experiencing hypoglycemia report having a headache. The brain's glucose shortage can trigger tension headaches.
• Weakness: Hypoglycemia deprives muscles of their energy source, resulting in general weakness and fatigue. You may experience muscle fatigue, making it hard to perform normal tasks.

When hypoglycemia progresses to the severe stage, the signs can become more dramatic:

• Loss of Consciousness: When glucose levels fall dangerously low, the brain ceases functioning correctly, causing loss of consciousness. This constitutes a medical emergency.
• Seizures: Severely low blood sugar can induce seizures by causing abnormal electrical activity in the brain. Seizures require prompt medical treatment.
• Slurred Speech: Impaired brain function due to glucose deficiency can manifest as difficulty speaking correctly and may present as slurred speech.
• Unresponsiveness: An individual with severe hypoglycemia might not respond to attempts to wake them or communicate with them.

What to Do Immediately

If someone is experiencing severe hypoglycemia and is conscious, follow these steps: Diabetes Management 10 Simple Habits For Stable Blood Sugar

1. Provide a Quick Source of Sugar: Offer them something sweet and quickly absorbed like fruit juice, regular (non-diet) soda, glucose tablets, or a sugary snack. About 15-20 grams of fast-acting carbohydrates should be enough.
2. Check Blood Sugar: If possible, check their blood sugar level 15 minutes after providing sugar.
3. Repeat if Necessary: If blood sugar is still low (below 70 mg/dL or 3.9 mmol/L) or symptoms persist, give another dose of fast-acting sugar.
4. Follow with a Complex Carbohydrate: Once blood sugar improves, provide a longer-lasting carbohydrate snack, such as crackers, bread, or fruit, to help stabilize levels.

If the person is unconscious or having a seizure:

1. DO NOT Give Food or Drink: Trying to force food or liquid into an unconscious person could cause them to choke.
2. Administer Glucagon (if available): If the person has a glucagon kit (a prescription medication to raise blood sugar), administer it according to the instructions. Glucagon is an injection that can quickly raise blood glucose levels.
3. Call for Emergency Medical Help: Call emergency services (911 in the US) immediately. Severe hypoglycemia is a medical emergency requiring prompt treatment.
4. Turn the Person on Their Side: To prevent choking should they vomit, gently turn the person onto their side in the recovery position.
5. Stay with the Person: Remain with the person until medical help arrives to ensure their safety and be ready to provide information to the paramedics.

Prevention Strategies

Preventing severe hypoglycemia is always preferable to treating it. Effective strategies for managing and avoiding hypoglycemia include:

• Regular Blood Sugar Monitoring: Individuals at risk should monitor their blood sugar levels regularly, especially before meals, before and after exercise, and at bedtime.
• Consistent Meal Timing: Eating regular meals and snacks at consistent times can help stabilize blood glucose levels. Skipping or delaying meals can trigger hypoglycemia.
• Medication Management: Work closely with your healthcare provider to ensure proper medication management. Dosage adjustments may be needed based on your diet, activity level, and overall health status.
• Carbohydrate Awareness: Learn how different foods affect your blood sugar. Balance carbohydrate intake with medication and activity to maintain stable glucose levels.
• Exercise Planning: Adjust medication or increase carbohydrate intake before and after exercise to prevent exercise-induced hypoglycemia.
• Alcohol Moderation: Drink alcohol in moderation and always with food. Avoid alcohol if your blood sugar is already low.
• Educate Family and Friends: Ensure that family members, friends, and caregivers recognize the signs of hypoglycemia and know how to respond appropriately, including how to administer glucagon.
• Carry Identification: Wear a medical identification bracelet or carry a card indicating you have diabetes and are at risk of hypoglycemia.

Long-Term Management and Potential Complications

Effective long-term management and prevention strategies are crucial to minimizing the risk and potential long-term impact of severe hypoglycemia. Potential long-term complications from frequent episodes include: A Hopeful Guide To Blood Glucose Management For Persons With Diabetes

• Cognitive Impairment: Recurring hypoglycemia episodes can affect cognitive function over time, potentially leading to problems with memory, attention, and overall brain health.
• Increased Risk of Cardiovascular Events: Hypoglycemia can trigger cardiovascular stress, potentially increasing the risk of heart problems in susceptible individuals.
• Hypoglycemia Unawareness: Repeated episodes of hypoglycemia can lead to a condition called "hypoglycemia unawareness," where individuals no longer experience the early warning signs of hypoglycemia. This increases the risk of severe hypoglycemia.
• Anxiety and Fear: Experiencing severe hypoglycemia can induce anxiety and fear of future episodes. This anxiety can affect daily life and adherence to treatment plans.

When to Seek Professional Help

While immediate actions are essential in managing severe hypoglycemia, certain situations warrant professional medical assistance:

• Frequent Hypoglycemic Episodes: Experiencing hypoglycemia frequently, even if not severe, requires evaluation by a healthcare provider to adjust your management plan.
• Hypoglycemia Unawareness: If you notice that you no longer experience the early warning signs of hypoglycemia, seek immediate medical advice.
• Unexplained Hypoglycemia: Experiencing hypoglycemia without an obvious cause (such as missed meals, excessive exercise, or medication changes) warrants medical evaluation.
• Persistent Symptoms: If symptoms of hypoglycemia persist even after consuming sugar, seek medical help.
• Loss of Consciousness or Seizure: As stated, these are medical emergencies that require immediate intervention.

Conclusion

Severe hypoglycemia is a serious medical condition, but with awareness, prompt action, and appropriate management, its risks can be mitigated. Recognizing the warning signs of hypoglycemia, knowing how to administer immediate treatment, and implementing long-term preventive strategies are vital for individuals at risk. Consult with a healthcare provider to develop a personalized management plan and address any concerns or questions you may have.
