Hypoglycemia Symptoms & Treatment: How to Safely Raise Low Blood Sugar

Hypoglycemia, or low blood sugar, is a condition that occurs when the level of glucose (sugar) in your blood drops too low. It's often associated with diabetes treatment, but can occur in people without diabetes as well. Recognizing the symptoms of hypoglycemia and knowing how to treat it promptly are crucial for preventing serious complications. This article provides a detailed overview of hypoglycemia, its causes, symptoms, and how to effectively and safely raise low blood sugar levels.

Understanding Hypoglycemia

Hypoglycemia is defined as a blood glucose level below 70 mg/dL. While it's more common in individuals with diabetes, certain medications, medical conditions, and lifestyle factors can also cause it. Understanding the potential causes and risk factors for hypoglycemia is the first step in preventing and managing the condition.

Common Causes of Hypoglycemia

• Diabetes Medications: Insulin and certain oral diabetes medications (sulfonylureas) are designed to lower blood sugar levels. Taking too much of these medications or not eating enough after taking them can lead to hypoglycemia.
• Skipping Meals or Not Eating Enough: Insufficient food intake or prolonged periods without eating can deplete glucose stores, leading to low blood sugar.
• Excessive Exercise: Strenuous physical activity can use up glucose quickly, particularly if you haven't eaten enough beforehand.
• Alcohol Consumption: Alcohol can interfere with the liver's ability to release glucose into the bloodstream, especially if consumed on an empty stomach.
• Certain Medical Conditions: Kidney disease, liver disease, and hormone deficiencies can affect blood sugar regulation.
• Certain Medications (Non-Diabetes Related): Some medications, like quinine (used to treat malaria) or pentamidine (used to treat pneumonia), can sometimes cause hypoglycemia.
• Post-Bariatric Surgery: Changes to the digestive system after weight-loss surgery can affect how the body absorbs and uses glucose.
• Reactive Hypoglycemia (Postprandial Hypoglycemia): This occurs a few hours after eating, usually due to the body releasing too much insulin in response to a meal high in carbohydrates.

Recognizing the Symptoms of Hypoglycemia

Early detection of hypoglycemia symptoms is vital. The symptoms can vary from person to person and can range from mild to severe. Being aware of the signs will allow for prompt treatment and prevent potential complications.

Early Symptoms of Hypoglycemia

These symptoms often appear first and serve as warning signs:

• Shakiness or Trembling
• Sweating
• Rapid Heartbeat
• Anxiety or Nervousness
• Irritability or Confusion
• Lightheadedness or Dizziness
• Hunger
• Tingling or Numbness around the Mouth

If left untreated, hypoglycemia can progress to more severe symptoms, requiring immediate medical attention:

• Difficulty Concentrating
• Slurred Speech
• Blurred Vision or Double Vision
• Weakness or Fatigue
• Seizures
• Loss of Consciousness
• Coma

It's crucial for individuals at risk for hypoglycemia, especially those with diabetes, to teach family members, friends, and coworkers how to recognize the signs of low blood sugar and how to administer treatment if necessary.

Treating Hypoglycemia: A Step-by-Step Guide

The primary goal of hypoglycemia treatment is to raise blood sugar levels back to the normal range (above 70 mg/dL) quickly and safely. The specific approach depends on the severity of the hypoglycemia and the person's ability to swallow and cooperate.

The 15-15 Rule

This is the standard approach for treating mild to moderate hypoglycemia in someone who is conscious and able to swallow:

1. Check Blood Sugar: If possible, check blood sugar levels with a glucose meter to confirm hypoglycemia.
2. Consume 15 Grams of Fast-Acting Carbohydrates: Examples include:
   • 3-4 glucose tablets
   • 1/2 cup (4 ounces) of fruit juice (orange, apple, or grape juice)
   • 1/2 can of regular (non-diet) soda
   • 1 tablespoon of honey or corn syrup
   • Hard candies (check the label for carbohydrate content; approximately 3-5 pieces)
3. Wait 15 Minutes: Allow the carbohydrate to be absorbed into the bloodstream.
4. Recheck Blood Sugar: After 15 minutes, recheck blood sugar levels.
5. Repeat if Necessary: If blood sugar is still below 70 mg/dL, repeat steps 2-4.
6. Eat a Meal or Snack: Once blood sugar is back within the target range, eat a meal or snack that contains both carbohydrates and protein to prevent another drop in blood sugar. Examples include:
   • Crackers with cheese
   • Peanut butter sandwich
   • Yogurt with fruit

Treating Severe Hypoglycemia

Severe hypoglycemia, characterized by loss of consciousness or seizures, requires immediate medical intervention.

• Glucagon Injection: Glucagon is a hormone that stimulates the liver to release stored glucose into the bloodstream. It is available as an injection and can be administered by a trained family member or caregiver. Follow the instructions provided by your doctor or pharmacist. It is important to note that glucagon may not be effective if the person's glucose stores are depleted, such as after prolonged fasting or heavy exercise.
• Call Emergency Services: After administering glucagon, call emergency services (911 in the US) for further medical assistance.
• Do Not Give Food or Drink: Do not attempt to give food or drink to someone who is unconscious, as this could cause choking.

It's important to note that glucagon is not a substitute for proper diabetes management, and repeated episodes of severe hypoglycemia should be discussed with a healthcare provider to adjust the diabetes treatment plan.

Preventing Hypoglycemia

Prevention is always the best approach. Several strategies can help minimize the risk of hypoglycemia, especially for individuals with diabetes.

• Monitor Blood Sugar Regularly: Frequent blood glucose monitoring provides valuable information about how food, exercise, and medications affect blood sugar levels. This information can be used to make adjustments to prevent hypoglycemia.
• Eat Regular Meals and Snacks: Consistent meal timing helps maintain stable blood sugar levels. Avoid skipping meals or waiting too long between meals.
• Adjust Insulin Dosage: Work closely with your doctor to adjust insulin dosages based on blood sugar levels, meal plans, and activity levels.
• Be Mindful of Alcohol Consumption: Limit alcohol intake, especially on an empty stomach. When consuming alcohol, always eat a meal or snack that contains carbohydrates.
• Plan for Exercise: Check blood sugar levels before, during, and after exercise. Adjust carbohydrate intake or insulin dosage as needed. Carry a source of fast-acting carbohydrates during exercise in case of hypoglycemia.
• Wear a Medical Identification: Wearing a medical ID bracelet or necklace indicating you have diabetes and are at risk for hypoglycemia can help emergency responders provide appropriate treatment if you are unable to communicate.
• Educate Family and Friends: Teach family members, friends, and coworkers how to recognize the signs of hypoglycemia and how to administer treatment if necessary. Keep glucagon readily available and ensure they know how to use it.

Hypoglycemia in People Without Diabetes

While less common, hypoglycemia can also occur in people without diabetes. Understanding the potential causes and seeking medical evaluation is important. This can involve conditions such as:

• Reactive Hypoglycemia (Postprandial Hypoglycemia): Occurs a few hours after eating, often after consuming a meal high in sugar or refined carbohydrates. Treatment typically involves dietary changes, such as eating smaller, more frequent meals and avoiding sugary foods.
• Fasting Hypoglycemia: Occurs after prolonged periods without eating. It can be caused by various underlying medical conditions, such as hormone deficiencies, liver disease, or certain tumors.
• Non-Islet Cell Tumor Hypoglycemia: Rare type where tumors produce insulin-like substances, causing low blood sugar.

It's important for anyone experiencing recurrent episodes of hypoglycemia, regardless of whether they have diabetes, to consult with a healthcare provider for a thorough evaluation and appropriate management.

When to Seek Medical Attention

While most cases of hypoglycemia can be managed at home with the 15-15 rule, there are situations when medical attention is necessary.

• Severe Hypoglycemia: Loss of consciousness, seizures, or inability to swallow.
• Recurrent Hypoglycemia: Frequent episodes of hypoglycemia despite following a treatment plan.
• Unexplained Hypoglycemia: Hypoglycemia in individuals without diabetes, especially if the cause is unknown.
• Hypoglycemia Unresponsive to Treatment: Blood sugar levels that do not improve after following the 15-15 rule.
