How to Support Someone Experiencing Severe Hypoglycemia Safely

Hypoglycemia, often called low blood sugar, can be a frightening experience, especially when it becomes severe. Knowing how to respond quickly and effectively can make a crucial difference in helping someone experiencing a hypoglycemic episode. This article provides detailed, actionable advice on how to support someone safely through severe hypoglycemia, recognizing symptoms, administering treatment, and understanding post-episode care.

Understanding Hypoglycemia and Its Severity

Before delving into support strategies, it's important to understand what hypoglycemia is and why it becomes a medical concern. Hypoglycemia occurs when the level of glucose (sugar) in the blood drops too low. This can happen for various reasons, most commonly in people with diabetes taking insulin or certain oral medications. Severe hypoglycemia is a medical emergency because the brain relies on glucose for energy, and a significant lack of glucose can lead to confusion, seizures, loss of consciousness, and even death if not treated promptly.

Recognizing the Signs and Symptoms of Severe Hypoglycemia

Prompt recognition is key to providing timely support. Symptoms of hypoglycemia vary from person to person, but some common indicators to look for include:

  • Confusion and Disorientation: Difficulty thinking clearly or understanding surroundings.
  • Loss of Coordination: Stumbling, slurred speech, or difficulty with motor skills.
  • Sweating and Shakiness: Unexplained and excessive sweating accompanied by tremors.
  • Irritability or Anxiety: Sudden mood changes, restlessness, or agitation.
  • Seizures: Involuntary muscle contractions and loss of awareness.
  • Loss of Consciousness: Unresponsiveness to stimuli.

It's important to note that not all individuals will experience all of these symptoms, and symptoms can sometimes mimic other medical conditions. However, in someone known to have diabetes or exhibiting a combination of these signs, suspect hypoglycemia.

Step-by-Step Guide to Assisting Someone Experiencing Severe Hypoglycemia

Here's a structured approach to help someone experiencing a severe hypoglycemic episode:

  1. Assess the Situation and Ensure Safety: First, quickly assess the immediate surroundings to ensure the person is in a safe place, away from hazards such as traffic or sharp objects. If the person is conscious but confused, try to gently guide them to a safe location.

  2. Determine Level of Consciousness: Try to rouse the person by speaking to them loudly or gently shaking their shoulder. Determine if they are able to respond to simple commands.

  3. If Conscious and Able to Swallow: Administer Fast-Acting Glucose:

    • Give Glucose Tablets or Gel: If available, give the person glucose tablets or glucose gel according to the package instructions. Typically, this involves 15-20 grams of fast-acting carbohydrates.
    • Provide a Sugary Drink: If glucose tablets or gel aren't available, offer a sugary drink such as juice (not diet) or regular soda (not diet). Avoid drinks high in fat, like milk, as these can slow down glucose absorption.
    • Offer Hard Candies: As a last resort, give hard candies to suck on.
    • Re-check Blood Sugar: If a blood glucose meter is available, check the person's blood sugar level. If it is below 70 mg/dL (or as defined by their doctor) continue with the fast-acting sugar.
  4. Wait 15 Minutes and Re-evaluate: After providing a source of quick sugar, wait 15 minutes and reassess the person's symptoms. If they are improving and can swallow, provide another serving of fast-acting glucose. If you checked blood sugar originally, check it again at the 15 minute mark.

  5. If Unconscious or Unable to Swallow: Administer Glucagon (If Available):

    • Locate the Glucagon Kit: If the person has a glucagon emergency kit, locate it immediately. Glucagon is a hormone that helps raise blood sugar levels by stimulating the liver to release stored glucose. Familiarize yourself with how to use a glucagon kit if you know someone at risk for hypoglycemia. Instructions vary with different brands.

    • Administer Glucagon: Follow the specific instructions that come with the glucagon kit. Typically, this involves injecting the glucagon into the thigh or upper arm.

    • Call for Emergency Medical Assistance (911 or local equivalent): Immediately after administering glucagon, call for emergency medical services. Explain that the person is experiencing severe hypoglycemia and has been given glucagon. Provide the operator with the person's medical history (if you know it), current symptoms, and any other relevant information.

  6. Position the Person Safely (If Unconscious): If the person is unconscious, place them on their side in the recovery position to prevent choking should they vomit.

  7. Do NOT Give Food or Drink to an Unconscious Person: Never attempt to give food or liquid to someone who is unconscious, as this could lead to choking.

  8. Monitor Vital Signs: While waiting for emergency medical personnel to arrive, continue to monitor the person's breathing and pulse. Diabetes Management A Daily Checklist For Stable Blood Sugar Levels

What to do after Glucagon is Administered?

Even after administering glucagon, it’s essential to still seek immediate medical attention. Glucagon is a temporary fix, and its effects are not always sustained. The underlying cause of the hypoglycemia needs to be investigated and properly managed by medical professionals. Expect that paramedics will administer additional glucose intravenously.

Post-Episode Care and Prevention

After the hypoglycemic episode has resolved, the following steps are important:

  • Consult with a Healthcare Provider: Encourage the person to follow up with their doctor or diabetes educator to review their diabetes management plan. This is essential for identifying the cause of the hypoglycemia and preventing future occurrences. The doctor will look at medication adjustments or insulin delivery timing.

  • Identify the Cause: Determine the factors that contributed to the low blood sugar. Common causes include:

    • Missed Meals or Snacks: Especially important when taking insulin or certain diabetes medications.
    • Excessive Insulin Dose: Too much insulin relative to food intake or activity level.
    • Unplanned Physical Activity: Exercise increases insulin sensitivity and glucose utilization.
    • Alcohol Consumption: Alcohol can interfere with the liver's ability to release glucose.
  • Adjust Diabetes Management Plan: Based on the identified causes, work with a healthcare provider to adjust medication dosages, meal timing, or exercise routines. Hypoglycemia Signs How To Recognize And Treat Low Blood Sugar

  • Educate Family and Friends: Ensure that family members, friends, and caregivers are educated about hypoglycemia, its symptoms, and how to respond in an emergency. Show them where glucagon is kept.

  • Wear a Medical ID: Encourage the person to wear a medical identification bracelet or necklace indicating that they have diabetes. This will alert first responders to their condition in an emergency.

Key Considerations for Assisting Someone with Hypoglycemia

Here are some additional points to keep in mind when supporting someone with severe hypoglycemia:

  • Stay Calm: Remain calm and reassuring, as your composure will help the person stay calm as well.
  • Communicate Clearly: Speak clearly and concisely, providing simple instructions.
  • Avoid Judgement: Do not judge the person or ask accusatory questions about their diabetes management. Focus on providing support.
  • Respect Privacy: Maintain the person's privacy and dignity throughout the episode.

Common Mistakes to Avoid

It's also important to be aware of common mistakes that can occur when assisting someone with hypoglycemia:

  • Delaying Treatment: Waiting too long to provide glucose or glucagon can worsen the condition.
  • Giving Insulin: Never administer insulin to someone experiencing hypoglycemia, as this will lower their blood sugar further.
  • Forcing Food or Drink: Do not force food or liquid into an unconscious person's mouth, as this could cause choking.
  • Assuming the Person is Intoxicated: Do not assume that the person is simply drunk or impaired. Look for other signs of hypoglycemia and take appropriate action.

Summary

Action Description Importance
