Hypoglycemia Explained: Symptoms, Causes, and How to Treat Low Blood Sugar

A sudden drop in blood sugar, clinically known as hypoglycemia, can be a disorienting and alarming event. Our comprehensive guide provides the essential, life-saving information you need to navigate it safely. We clearly outline the primary causes, helping you understand the triggers behind these episodes. Crucially, we detail the full spectrum of warning signs—from mild shakiness and sweating to more severe confusion—so you can recognize and act on them immediately. Most importantly, this guide gives you clear, step-by-step instructions on effective treatment, including the "Rule of 15," so you can confidently and correctly manage a hypoglycemic event and know when it's time to seek emergency help.

What is Hypoglycemia?

Hypoglycemia occurs when your blood glucose levels drop below the normal range. For most people without diabetes, this is generally considered to be below 70 mg/dL (3.9 mmol/L). It's more common in individuals with diabetes, particularly those taking insulin or certain oral medications, but can occasionally occur in people without diabetes as well. Understanding the underlying causes and recognizing the symptoms are key to managing and preventing these episodes.

Causes of Hypoglycemia

Several factors can contribute to low blood sugar. Here's a breakdown of the common culprits:

Diabetes Medications: This is the most frequent cause. Taking too much insulin or certain oral diabetes medications can quickly lower blood sugar.
Skipping or Delaying Meals: Not eating enough carbohydrates throughout the day can lead to a drop in blood sugar.
Excessive Exercise: Physical activity uses glucose for energy. Without adequate carbohydrate intake to compensate, blood sugar can fall.
Alcohol Consumption: Alcohol can interfere with the liver's ability to release stored glucose.
Certain Medical Conditions: Rarely, medical conditions like insulinomas (insulin-producing tumors) or hormonal deficiencies can cause hypoglycemia.
Rebound Hypoglycemia: After a period of high blood sugar, the body may release extra insulin, leading to a subsequent drop in blood sugar.
Medications: Some medications, like certain antibiotics and sulfa drugs, can affect blood sugar levels.

Recognizing the Symptoms: From Mild to Severe

Symptoms of hypoglycemia can vary in severity, depending on how low your blood sugar drops and how quickly. It’s vital to be aware of these signs and act promptly.

Mild Hypoglycemia (Blood sugar between 55-70 mg/dL):
- Shakiness
- Sweating
- Dizziness
- Hunger
- Irritability
- Rapid heartbeat
- Anxiety
Moderate Hypoglycemia (Blood sugar between 40-55 mg/dL):
- Confusion
- Blurred vision
- Slurred speech
- Weakness
- Difficulty concentrating
Severe Hypoglycemia (Blood sugar below 40 mg/dL):
- Loss of consciousness
- Seizures
- Inability to eat or drink

Important Note: Some individuals, particularly those who frequently experience hypoglycemia, may lose the ability to recognize the early warning signs (hypoglycemia unawareness). Regular blood glucose monitoring is crucial in these cases.

The "Rule of 15" - Treatment for Mild to Moderate Hypoglycemia

The "Rule of 15" is a simple and effective method for treating mild to moderate hypoglycemia:

Check Your Blood Sugar: If possible, confirm your blood sugar is below 70 mg/dL.
Consume 15 Grams of Fast-Acting Carbohydrates: Examples include:
- 4 ounces (1/2 cup) of juice or regular soda (not diet)
- 1 tablespoon of honey or sugar
- 3-4 glucose tablets
- 1 tube of glucose gel
Wait 15 Minutes: Allow the carbohydrates time to raise your blood sugar.
Recheck Your Blood Sugar: After 15 minutes, check your blood sugar again.
Repeat if Necessary: If your blood sugar is still below 70 mg/dL, repeat the process (step 1-4).
Eat a Snack: Once your blood sugar is above 70 mg/dL, eat a snack containing protein and carbohydrates (e.g., crackers with peanut butter, cheese and fruit) to prevent another drop.

Treatment for Severe Hypoglycemia

Severe hypoglycemia requires immediate assistance. If someone is unconscious or experiencing seizures:

Do Not Give Anything by Mouth: They are unable to swallow safely.
Administer Glucagon: If you have been prescribed glucagon, administer it according to the instructions. Glucagon is a hormone that stimulates the release of stored glucose.
Call Emergency Services (911): Even after administering glucagon, it's crucial to seek medical attention.

Preventing Hypoglycemia

Regular Blood Glucose Monitoring: Especially important for those with diabetes.
Consistent Meal Times: Don't skip meals or delay them for long periods.
Carbohydrate Awareness: Understand the carbohydrate content of your meals and snacks.
Medication Management: Follow your doctor’s instructions carefully regarding medication dosages and timing.
Exercise Planning: Adjust your carbohydrate intake based on your activity level.
Alcohol Moderation: Consume alcohol in moderation and always with food.
Carry a Fast-Acting Carbohydrate: Keep glucose tablets, juice, or other fast-acting carbohydrates readily available.
Educate Others: Inform family, friends, and coworkers about your condition and what to do in case of a hypoglycemic episode.
