Low Blood Sugar (Hypoglycemia): What You Should Know and Do

Low blood sugar, or hypoglycemia, is a condition that occurs when the level of glucose (sugar) in your blood drops too low. This can be a serious issue, particularly for individuals with diabetes, but it can also affect people without diabetes in certain circumstances. Understanding the causes, symptoms, and management of hypoglycemia is crucial for maintaining your health. In this comprehensive guide, we will delve deep into this common condition, providing you with actionable information.

Understanding Hypoglycemia

Your body needs a consistent level of glucose to function correctly, especially the brain, which relies almost exclusively on it. When blood glucose levels drop below 70 mg/dL, it is generally considered hypoglycemia. The severity can vary, ranging from mild to severe, and prompt action is essential to restore blood sugar levels to a healthy range.

Here’s why maintaining healthy glucose levels matters:

• Energy Supply: Glucose is your body's primary source of energy.
• Brain Function: The brain relies heavily on glucose for its operations, so when sugar levels fall too low, cognitive functions are immediately impaired.
• Cellular Processes: Cells need the energy derived from glucose to carry out their regular activities.

Blood Glucose Level (mg/dL)	Condition	Implication
Less than 70	Hypoglycemia	Requires immediate intervention to raise blood glucose
70-100	Normal (Fasting)	Ideal fasting blood glucose level
100-125	Pre-Diabetes	Elevated glucose, risk of developing diabetes
126 or more	Diabetes	Significantly elevated blood glucose requiring management

Causes of Hypoglycemia

Hypoglycemia can occur due to various reasons, and pinpointing the cause is key to preventing future episodes. Here are some major triggers:

For Individuals with Diabetes:

• Insulin Overdose: Taking too much insulin or other diabetes medications can cause blood sugar to plummet.
• Missed also known as blood sugar or Delayed Meals: Skipping meals or not eating enough carbohydrates after taking insulin can lead to hypoglycemia.
• Increased Physical Activity: Unplanned exercise can rapidly deplete blood sugar, especially if medication adjustments are not made.
• Alcohol Consumption: Alcohol can interfere with the liver’s ability to release glucose into the bloodstream, particularly when consumed on an empty stomach.

For Individuals Without Diabetes:

• Reactive Hypoglycemia: Occurs within a few hours after a meal. The body overreacts to glucose consumption by releasing excessive insulin.
• Fasting Hypoglycemia: Often due to an underlying condition, it occurs when the body doesn’t produce or use glucose properly.
• Medical Conditions: Conditions like kidney disease, liver disease, and adrenal or pituitary gland issues can sometimes cause hypoglycemia.
• Certain Medications: Certain drugs, even if not diabetes-related, can have side effects that may lead to low blood sugar.
• Post-Gastric Bypass: After certain bariatric surgeries, there’s a higher risk of low blood sugar.

Understanding these causes helps to put the condition into perspective and create more targeted prevention and management plans.

Symptoms of Hypoglycemia

Recognizing the symptoms of hypoglycemia early is essential to treat it promptly and avoid more severe complications. Symptoms may differ from person to person, but here are some of the most commonly experienced ones:

Mild to Moderate Hypoglycemia Symptoms:

• Shakiness or Trembling: A sudden, uncontrollable trembling.
• Sweating: Unexplained, excessive perspiration.
• Dizziness or Lightheadedness: Feeling faint or unstable.
• Confusion: Difficulty concentrating or remembering things.
• Rapid Heartbeat: Increased or noticeable heart rate.
• Irritability or Anxiety: Sudden feelings of agitation or nervousness.
• Hunger: Extreme and sudden hunger, even if you've recently eaten.
• Weakness: Feeling tired and drained without exertion.
• Pale Skin: Noticeably paler than usual skin tone.

Severe Hypoglycemia Symptoms:

• Loss of Consciousness: Fainting or inability to stay awake.
• Seizures: Uncontrollable jerking movements.
• Confusion and Disorientation: Extreme difficulty understanding what is happening or where you are.
• Difficulty Speaking: Slurred speech or inability to speak.

It’s important to note that not everyone will experience all symptoms and some people complications of high blood sugar levels might feel completely different, for example, just feeling slightly dizzy. Furthermore, people with long-term diabetes may experience hypoglycemia unawareness, where they no longer recognize the early warning signs. Therefore, having regular checks of blood sugar levels is crucial, especially for individuals with a diabetes diagnosis or those at risk.

How to Treat Hypoglycemia

Treatment for hypoglycemia aims at raising the blood glucose level back to a safe range. The approach depends on the severity of the low blood sugar. It is always wise to err on the side of caution.

For Mild to Moderate Hypoglycemia:

1. The 15-15 Rule: Consume 15 grams of fast-acting carbohydrates and wait 15 minutes.
   • Examples of 15 grams of quick-acting carbs:
     • Glucose tablets (follow instructions on the packaging)
     • 4 ounces (1/2 cup) of regular (not diet) soda or juice.
     • 1 tablespoon of honey or sugar
     • 8 ounces of low-fat milk
     • 4-5 hard candies
   • Recheck blood sugar after 15 minutes. If it's still below 70 mg/dL, repeat the above steps.
   • Once blood sugar is back in range, eat a small snack to stabilize levels like half a sandwich, some cheese and crackers, or a piece of fruit.
2. Don’t Over-treat: Excessively treating a low glucose can result in hyperglycemia (high blood sugar), and can make things difficult. Aim to bring the glucose back into the optimal range.

For Severe Hypoglycemia:

• Glucagon Administration: If the person is unconscious or having a seizure, administer glucagon if available and if you have been trained on its use. Glucagon is a hormone that increases blood sugar.
• Seek Emergency Help: Call 911 or emergency services if glucagon is unavailable or ineffective, or if the person has severe symptoms.

Here’s a table summarizing the treatment:

Severity	Symptoms	Treatment
Mild to Moderate	Shaking, sweating, dizziness, hunger	15 grams of fast-acting carbs, recheck in 15 min. Repeat as needed. Snack after.
Severe	Loss of consciousness, seizures, disorientation	Glucagon injection, emergency medical help needed

Special Considerations:

• Hypoglycemia Unawareness: Individuals who don't feel the early symptoms may need to monitor their blood glucose more often.
• Personalized Plan: Work with a healthcare provider to develop an individualized management plan.
