Hypoglycemia, often called low blood sugar, is a condition where the level of glucose in your blood drops below normal. Glucose is your body's primary source of energy, so when it gets too low, it can lead to a variety of symptoms, some mild and others severe. Understanding hypoglycemia and knowing how to react appropriately is crucial for anyone at risk, including individuals with diabetes, those on certain medications, or people who experience reactive hypoglycemia. It’s a condition that can be both frightening and disruptive, but with the right knowledge and prompt action, you can manage it effectively. This article aims to equip you with the practical knowledge and steps to react appropriately to an episode of hypoglycemia.

Why Is It Important to Know How to React to Hypoglycemia?

Prevent Severe Episodes: Mild hypoglycemia, if left unchecked, can escalate into severe episodes requiring medical intervention, potentially leading to loss of consciousness, seizures, or coma. Knowing how to respond at the first sign can prevent these severe situations.
Immediate Relief of Symptoms: Prompt action provides immediate relief from the unpleasant and disorienting symptoms, improving the person’s comfort and ability to function.
Avoidance of Complications: Repeated or severe hypoglycemia can contribute to other health problems. Early intervention helps minimize any associated risks.
Maintain Daily Routine: Managing hypoglycemia proactively means being able to continue regular activities without severe interruption, allowing for greater independence and confidence in managing one’s health.

Recognizing the Symptoms of Hypoglycemia

The symptoms of hypoglycemia can vary from person to person and can also differ in intensity. It’s vital to be able to recognize the signs early to initiate quick and effective action. Symptoms can be grouped into mild to moderate and severe, each needing specific responses.

Mild to Moderate Symptoms

These are usually the initial indicators and are easier to manage:

Shakiness or Trembling: This is a common early sign, often felt in the hands, but can affect the whole body.
Sweating: Often unprovoked, this can include excessive sweating, clamminess and a sense of being damp.
Dizziness or Lightheadedness: A feeling of spinning, instability, or being about to faint.
Confusion or Difficulty Concentrating: You might feel fuzzy headed, struggle to think clearly, make simple errors and become forgetful
Rapid Heartbeat: An increased heart rate or a feeling of pounding in your chest may occur.
Irritability or Anxiety: Experiencing unexplained mood swings or nervousness.
Hunger: Feeling excessively hungry or developing cravings.
Tingling or Numbness: Numbness in the lips, tongue, or fingers is possible.
Pale Skin: A noticeably pale or ashen complexion.

Severe Symptoms

These indicate a significant drop in blood sugar, requiring immediate medical intervention:

Loss of Consciousness: Fainting, unresponsiveness, or a significant reduction in awareness.
Seizures or Convulsions: Uncontrolled body spasms or fits.
Difficulty Speaking or Slurred Speech: Trouble communicating clearly, making speech difficult to understand.
Inability to Swallow: Trouble getting food down is not only serious, but also hinders any effective treatment options
Extreme Weakness: Profound lethargy or inability to move normally.

Note: The symptoms of hypoglycemia can also mimic other medical conditions. It is best to have any unusual symptoms checked if they persist or worsen

Symptom Category	Common Signs	Immediate Action Required
Mild to Moderate	Shakiness, Sweating, Dizziness	Consume quick sugar source
Mild to Moderate	Confusion, Rapid Heartbeat, Irritability	Test blood glucose level
Mild to Moderate	Hunger, Tingling, Pale skin	Check for symptoms after 15 minutes
Severe	Loss of Consciousness, Seizures	Seek Emergency Medical help
Severe	Slurred speech, Difficulty speaking or swallowing	Administer glucagon and seek help immediately
Severe	Extreme weakness	Wait for help and stay responsive

The 15-15 Rule for Mild Hypoglycemia

When experiencing mild to moderate symptoms of hypoglycemia, the “15-15 Rule” is an essential guideline to follow. This rule provides a structured approach for how to raise blood sugar levels quickly and effectively.

What is the 15-15 Rule?

Consume 15 Grams of Fast-Acting Carbohydrates: The first step involves eating or drinking something that will raise blood sugar levels rapidly. Suitable options include:
- 4-6 ounces (120-180 ml) of fruit juice (not diet).
- 4-5 glucose tablets.
- 1 tablespoon of honey or sugar.
- 1 tube of glucose gel
- 6-8 hard candies that are not sugar-free.
- ½ can of sugary soft drink (Not Diet).
Wait 15 Minutes: Following the consumption of a fast-acting carbohydrate source, wait 15 minutes before checking blood glucose levels again. It is important to give your body the chance to respond without any outside interference, in order to gauge its reaction.
Recheck Blood Glucose Levels: Use a glucose meter to measure your blood sugar levels. The aim should be a level above 70 mg/dL.
Repeat if Necessary: If blood sugar is still below 70 mg/dL after 15 minutes, repeat steps one and two (Consume a further 15 g of carbohydrates and recheck after another 15 minutes.)
Eat a Meal or Snack: Once blood glucose is within target range, eat a meal or snack that includes longer-acting carbohydrates and proteins. This can be a meal that you normally would have or it can be a nutritious snack such as a piece of wholemeal toast with a cheese portion, or a handful of nuts and a glass of milk. This will help to stabilise your blood glucose and prevent it from dropping again.

Why 15 Grams of Fast-Acting Carbs?

Fast Absorption: These sources are chosen because they can be absorbed into the bloodstream quickly, raising blood sugar promptly,
Consistent Measure: Using a set amount, like 15 grams, helps standardize the approach, reducing guesswork.
Balance: Using less carbohydrate would not have a fast enough effect and more carbohydrate would elevate blood sugar too high, causing its own issues.

Step	Action	Timing	Rationale
Step 1: Treat	Consume 15 grams of fast-acting carbohydrates	Immediate	Provides rapid glucose supply to elevate blood sugar.
Step 2: Wait	Wait 15 minutes	15 mins	Allows enough time for carbohydrates to take effect.
Step 3: Recheck	Check blood glucose level	+15 mins	Verify if blood sugar has reached a safe level.
Step 4: Repeat	Repeat Step 1 and 2 if glucose is still below 70 mg/dL	If needed	Provides additional glucose if blood sugar hasn’t responded adequately.
Step 5: Meal/Snack	Eat a longer-lasting meal or snack	After Blood Sugar has stabilized	Prevents future lows by providing sustained energy.

Note: If blood sugar does not come up after two attempts at the 15-15 rule, it may indicate another health problem or medication interaction, please seek medical assistance at your earliest opportunity.

Responding to Severe Hypoglycemia

Severe hypoglycemia is a medical emergency and requires prompt action. A person experiencing severe symptoms may be unable to treat themselves. Therefore, those around a person at risk need to know what to do.

Key Actions During Severe Hypoglycemia:

Do not leave the person alone: Maintain their position, don’t move them if not necessary.
Do not force liquids or food: Trying to get an unresponsive person to swallow will risk choking them and can potentially cause permanent lung damage if aspiration occurs.
Administer Glucagon if Available: If the person uses glucagon, it should be given as per their instructions (This is usually as an injection but in some places, nasal forms are used). Glucagon is a hormone that raises blood sugar by stimulating the liver to release stored glucose into the bloodstream. Check the expiration date and make sure that it is still usable.
Call for Emergency Medical Help Immediately: Dial emergency services (911 or local emergency number), clearly stating the emergency, and that it involves suspected or known hypoglycemia.
Provide Information: If someone can talk to you clearly, ask whether they have diabetes or take medication for diabetes. Make a note of anything you have given the person and at what time. Tell the paramedics or emergency personnel any medications that you know the person takes and any recent history or events that may have caused the drop in blood sugar.
Monitor and Support: Wait with the person until the emergency help arrives. Keep them as comfortable as possible, loosen tight clothing and remove anything from around the neck.
Document the Episode: Note down what you saw and what treatment you gave. Any episodes of severe hypoglycemia should be reported to their medical professional so that any underlying problems can be found.
Educate others: Help others understand what hypoglycemia is, so that if an episode should occur, they know what to look for and know what action to take.

Glucagon Administration: Key Points

Location: Inject glucagon into the thigh, arm, or abdomen. The person who can best help them with this injection should perform the injection.
Preparation: If necessary, reconstitute (mix) glucagon powder with liquid, then use it immediately. Always follow the specific instructions that are given by the manufacturer
After Use: After administering glucagon, monitor the person closely for any changes, document the injection, and note what time it was given.
Follow up: Following use, ensure to check with a medical professional so that the hypoglycemia episode can be recorded, the effects can be monitored, and future actions can be put in place.

Post-Severe Episode Care:

Hospital Assessment: Those who experience severe hypoglycemia should seek an urgent medical assessment at their nearest hospital, to monitor and find the cause.
Medical Team Follow-Up: Follow up with the healthcare team to investigate the cause of the hypoglycemia and find a plan to minimize any reoccurrences.
Changes: Reassessment of medication and dosage, and discussion of dietary needs may need to happen in response to a recent severe event.

Action	Immediate Steps	Why?
Safety	Do not leave the person alone, do not give oral food, call for medical help	Prevents further harm, ensures prompt and qualified treatment.
Glucagon	Administer glucagon as instructed, then note what was done and when	Provides the hormone to release stored glucose into the bloodstream.
Emergency Contact	Call for emergency services immediately	Guarantees rapid professional intervention.
Communication	Provide available information	Supports healthcare professionals in determining the cause and planning care effectively.
Monitoring	Stay with the person, keep calm, wait for emergency medical help	Helps stabilize the person and reassures the individual
Post-Event Care	Document the event and follow-up care with the medical professional	Provides a future treatment plan

Preventive Measures: Minimizing the Risk of Hypoglycemia

Prevention is the key when it comes to hypoglycemia. Understanding risk factors and taking preventive actions can minimize episodes:

Tips to Prevent Hypoglycemia:

Regular Monitoring: Regularly check blood glucose levels if you are prone to hypoglycemia, at the frequency recommended by your doctor. Maintain and follow any records given to you.
Medication Management: Follow your prescribed medication schedule precisely. Do not miss doses or adjust dosages without consulting your healthcare provider. If your medication is causing hypoglycemia, discuss possible medication changes with your medical team
Meal Planning: Plan meals and snacks to maintain regular intake, paying special attention to carbohydrate intake, complex and simple sugars. Talk with a dietitian if needed.
Carbohydrate Balance: Pair your carbohydrate intake with protein and healthy fats to stabilize blood glucose levels for a longer duration.
Exercise Planning: Plan exercise routines, ensuring there is sufficient food and monitoring throughout exercise. Also note that vigorous exercise can cause dips in blood glucose levels for several hours afterwards. Always have snacks and sugars on hand and close by.
Alcohol: If consuming alcohol, eat some food beforehand, and be aware that alcohol can reduce the effects of certain medications or increase the risk of hypoglycemia. Limit how much alcohol you consume, especially when managing blood sugar levels. Avoid drinking alcohol on an empty stomach.
Illness: Be mindful that illness can alter how your body responds to certain medications and meals. Consult a medical professional if you are experiencing severe changes to your appetite, digestion, or routine.
Wear Identification: Always wear an ID bracelet or carry a card that indicates your condition and includes emergency contact information. Ensure to have a full understanding of your healthcare records and any plans relating to your personal situation.
Keep a Supply: Always have a supply of easily accessible glucose tablets, gels, or sugar available in all your usual locations such as bags, vehicles, and work areas.
Continuous Glucose Monitoring: If you are at a high risk of frequent or severe hypoglycemia, speak to your medical team to discuss the possible option of using continuous blood glucose monitoring devices, that can offer real-time alerts to problems with blood glucose levels.
