Severe Hypoglycemia: Emergency Signs and What to Do When Blood Sugar Crashes

Hypoglycemia, commonly known as low blood sugar, occurs when the level of glucose in your blood drops below normal. While mild hypoglycemia can often be managed with a quick snack, severe hypoglycemia is a dangerous condition that requires immediate attention. Understanding the emergency signs and knowing what to do when someone experiences a significant blood sugar crash can be life-saving. This article will provide detailed information on recognizing, responding to, and preventing severe hypoglycemic episodes.

Understanding Hypoglycemia: A Quick Overview

Before diving into severe hypoglycemia, it’s essential to understand the basics of blood sugar regulation. Glucose is the primary source of energy for your body, derived from the food you eat. Insulin, a hormone produced by the pancreas, helps glucose enter your cells for energy use. In people with diabetes, the balance between insulin and glucose can be disrupted, leading to either hyperglycemia (high blood sugar) or hypoglycemia.

| Factor | Normal Range | Hypoglycemic Range | | ------------------ | ------------------------------------------ | ------------------------------------------ | | Blood Sugar Level | 70-100 mg/dL (fasting) | Below 70 mg/dL | | Common Causes | Balanced diet, regular exercise, proper medication | Skipping meals, excessive insulin, intense exercise | | Symptoms (Mild) | Shakiness, sweating, hunger | Confusion, dizziness, loss of consciousness |

Severe hypoglycemia occurs when blood sugar levels drop so low that the individual becomes unable to treat themselves and requires assistance from another person.

Recognizing the Emergency Signs of Severe Hypoglycemia

Severe hypoglycemia can manifest in various ways, and recognizing the signs early is critical. The symptoms can range from mild to severe, and they can sometimes mimic other medical conditions, making prompt recognition essential.

Common Emergency Signs:

Loss of Consciousness: This is one of the most alarming signs. The individual may become unresponsive, making it impossible for them to treat themselves.
Seizures: Low blood sugar can disrupt normal brain function, leading to seizures, which are characterized by uncontrolled muscle contractions and loss of awareness.
Confusion and Disorientation: Extreme confusion, difficulty speaking, or an inability to follow simple instructions are common signs of severe hypoglycemia.
Severe Weakness or Incoordination: The person may be unable to stand or walk without assistance due to profound muscle weakness.
Behavioral Changes: Unusual irritability, aggression, or irrational behavior can occur due to the brain being deprived of glucose.

It’s important to note that not everyone will experience all of these symptoms. Some individuals may exhibit only one or two signs, while others may experience a combination of symptoms. Being aware of these potential indicators is crucial for timely intervention.

Real-Life Scenario:

Imagine you are at a family gathering and notice that your grandfather, who has diabetes, is acting strangely. He seems confused, is having difficulty speaking, and is unusually irritable. You ask him if he feels okay, but he doesn't seem to understand your question. This could be a sign of severe hypoglycemia, and immediate action is necessary.

Immediate Actions to Take When Blood Sugar Crashes

When someone shows signs of severe hypoglycemia, prompt and appropriate action is essential. The primary goal is to raise their blood sugar levels quickly and safely.

Step-by-Step Guide to Responding to Severe Hypoglycemia:

Check for Responsiveness: Gently try to wake the person and see if they respond to your voice or touch. If they are conscious and able to swallow, proceed to step 2. If they are unconscious, proceed to step 4.
Administer Fast-Acting Carbohydrates (if conscious): Give the person a source of quick-acting carbohydrates, such as:
- Glucose Tablets: Follow the instructions on the package, usually 3-4 tablets.
- Glucose Gel: Apply the gel inside their cheek if they have difficulty swallowing.
- Juice or Regular Soda: Offer about 4 ounces (120 ml) of juice or non-diet soda.
- Hard Candies: If other options are not available, give them a few hard candies to suck on.
Wait and Monitor: After administering the carbohydrates, wait about 15 minutes and recheck the person’s blood sugar if a meter is available. If they are feeling better and their blood sugar is rising, offer a snack containing both carbohydrates and protein (e.g., crackers with peanut butter) to stabilize their blood sugar.
Administer Glucagon (if unconscious or unable to swallow): Glucagon is a hormone that stimulates the liver to release stored glucose into the bloodstream. If the person is unconscious or unable to swallow, do not attempt to give them anything by mouth. Instead:
- Locate the Glucagon Kit: If the person has diabetes, they should have a glucagon emergency kit. Check their belongings or ask family members if they have one.
- Prepare the Glucagon Injection: Follow the instructions in the kit to prepare the glucagon injection. Typically, you will need to mix a powder with a liquid.
- Administer the Injection: Inject the glucagon into the thigh muscle, following the kit’s instructions.
- Call for Emergency Medical Assistance: Immediately call emergency services (911 in the US) or your local emergency number, and provide them with the person's location and condition.
Monitor and Provide Support: After administering glucagon, the person should regain consciousness within 5-15 minutes. Once they are awake and able to swallow, give them a source of carbohydrates and protein to stabilize their blood sugar.
Seek Medical Attention: Even if the person recovers after receiving glucagon, it’s crucial to seek medical attention. Severe hypoglycemic episodes can have underlying causes that need to be addressed by a healthcare professional.

| Action | When to Perform | Important Considerations | | --------------------------------------- | --------------------------------------------------- | --------------------------------------------------------------------------------------------------- | | Administer Fast-Acting Carbohydrates | Person is conscious and able to swallow | Avoid overfeeding, as this can lead to a rapid spike in blood sugar. | | Administer Glucagon | Person is unconscious or unable to swallow | Follow kit instructions carefully. Glucagon may cause nausea or vomiting upon regaining consciousness. | | Call Emergency Medical Services (EMS) | Person is unconscious, has seizures, or does not improve | Provide accurate information about the person’s condition and medical history. |

Common Mistakes to Avoid:

Forcing Food or Drink into an Unconscious Person: This can cause choking and be extremely dangerous.
Delaying Action: The longer the brain is deprived of glucose, the greater the risk of complications. Act quickly and decisively.
Assuming Recovery is Complete: Even if the person appears to recover, it’s essential to seek medical attention to identify and address the underlying cause of the hypoglycemia.

Preventing Severe Hypoglycemia: Long-Term Strategies

While knowing how to respond to severe hypoglycemia is crucial, preventing it in the first place is even more important. Implementing the following strategies can significantly reduce the risk of severe blood sugar crashes.

Strategies for Preventing Severe Hypoglycemia:

Regular Blood Sugar Monitoring: People with diabetes should monitor their blood sugar levels regularly, as recommended by their healthcare provider. Keeping track of blood sugar readings can help identify patterns and potential triggers for hypoglycemia.
Medication Management: Work closely with your healthcare team to ensure your diabetes medications are appropriately dosed and timed. Avoid skipping doses or taking more medication than prescribed.
Meal Planning: Eat regular, balanced meals and snacks to maintain stable blood sugar levels. Avoid skipping meals or drastically reducing carbohydrate intake.
Exercise Management: Exercise can lower blood sugar levels, so it’s important to monitor your blood sugar before, during, and after physical activity. Adjust your medication or carbohydrate intake as needed to prevent hypoglycemia.
Alcohol Consumption: Alcohol can interfere with blood sugar control, especially when consumed on an empty stomach. If you choose to drink alcohol, do so in moderation and always eat food at the same time.
Hypoglycemia Awareness: Learn to recognize the early symptoms of hypoglycemia and take action promptly. Educate family members, friends, and coworkers about hypoglycemia and how to assist you if needed.
Carry Identification: Wear a medical identification bracelet or necklace that indicates you have diabetes. This can alert first responders to your condition in case of an emergency.
