Feeling Dizzy or Shaky? When to Check for Low Blood Sugar
Experiencing dizziness or shakiness can be alarming. While many factors can cause these symptoms, one common culprit, especially for individuals with diabetes or certain health conditions, is low blood sugar, also known as hypoglycemia. This article will explore the connection between dizziness, shakiness, and low blood sugar, helping you understand when it's essential to check your blood glucose levels and what steps to take.
Understanding Low Blood Sugar (Hypoglycemia)
Hypoglycemia occurs when the glucose (sugar) level in your blood drops below the normal range. Glucose is the primary energy source for your body, and when levels become too low, it can affect your brain and other organs. Normal blood sugar levels generally fall between 70 mg/dL and 140 mg/dL. If your blood sugar dips below 70 mg/dL, you're considered hypoglycemic and should take action.
Common Causes of Hypoglycemia
Several factors can contribute to low blood sugar:
- Diabetes Medications: Insulin and certain oral diabetes medications can sometimes cause blood sugar to drop too low if the dosage is incorrect or if you skip a meal.
- Skipping Meals or Eating Too Little: When you don't eat enough, your body doesn't have enough glucose to function properly.
- Intense Exercise: Strenuous physical activity can use up glucose rapidly, leading to hypoglycemia, especially if you aren't consuming enough carbohydrates.
- Alcohol Consumption: Alcohol can interfere with the liver's ability to release glucose into the bloodstream, potentially causing low blood sugar, especially when consumed without food.
- Certain Medical Conditions: Liver or kidney disease, hormonal deficiencies, and tumors that produce insulin can also contribute to hypoglycemia.
Why Dizziness and Shakiness Indicate Low Blood Sugar
When your blood sugar drops too low, your brain doesn't get the energy it needs to function correctly. This triggers a series of symptoms as your body tries to compensate. Dizziness and shakiness are among the most common early warning signs because:
- Dizziness: The brain's dependence on glucose means that a deficiency can lead to lightheadedness, a spinning sensation, or general dizziness.
- Shakiness: Your body releases adrenaline (epinephrine) in response to low blood sugar. Adrenaline prepares your body for a "fight or flight" response, causing your muscles to shake.
Other Symptoms of Low Blood Sugar
Besides dizziness and shakiness, other common symptoms of hypoglycemia include:
- Sweating
- Rapid heartbeat
- Anxiety or nervousness
- Irritability or confusion
- Blurred vision
- Headache
- Weakness
- Hunger
In severe cases, hypoglycemia can lead to seizures, loss of consciousness, and even coma, emphasizing the importance of prompt recognition and treatment.
When to Check Your Blood Sugar
If you experience dizziness or shakiness, especially if you have diabetes or are at risk for hypoglycemia, it's crucial to check your blood sugar levels as soon as possible.
Here's a guideline for when to check:
- Whenever you experience symptoms of low blood sugar: Don't ignore the warning signs. Even if you're not sure, it's better to be safe and check.
- Before meals: Checking before eating helps you determine if your blood sugar is within the target range and allows you to adjust your insulin or medication dosage accordingly.
- Two hours after meals: This check helps you see how your body responds to food and whether your insulin is working effectively.
- Before bedtime: This check helps prevent nighttime hypoglycemia, which can be dangerous.
- Before, during, and after exercise: Monitoring your blood sugar during physical activity allows you to adjust your food intake or insulin dosage to avoid low blood sugar.
- If you feel unwell: If you experience unexplained dizziness, shakiness, or other unusual symptoms, checking your blood sugar can help identify if hypoglycemia is the cause.
How to Check Your Blood Sugar
Checking your blood sugar involves using a blood glucose meter. Here are the basic steps:
- Wash your hands: Clean hands help prevent infection.
- Prepare your lancing device: Insert a new lancet into the lancing device.
- Insert a test strip into your meter: Make sure the meter is turned on and ready to receive a blood sample.
- Prick your finger: Use the lancing device to prick the side of your fingertip.
- Apply blood to the test strip: Gently squeeze your finger to get a small drop of blood and touch it to the test strip.
- Wait for the results: Your blood glucose meter will display your blood sugar level within a few seconds.
What to Do If Your Blood Sugar Is Low
If your blood sugar level is below 70 mg/dL, you need to take immediate action to raise it.
The "15-15 Rule" is a commonly recommended approach:
-
Consume 15 grams of fast-acting carbohydrates: These are easily absorbed by the body and quickly raise blood sugar levels. Examples include: Common Mistakes That Cause Postprandial Blood Sugar Spikes After Eating
- 4 ounces (1/2 cup) of juice or regular (non-diet) soda
- 1 tablespoon of sugar, honey, or corn syrup
- 3-4 glucose tablets or gel
- Hard candies (check the label for carbohydrate content)
-
Wait 15 minutes and recheck your blood sugar: After consuming carbohydrates, wait 15 minutes and then check your blood sugar again to see if it has risen.
-
Repeat if necessary: If your blood sugar is still below 70 mg/dL, repeat the process of consuming 15 grams of carbohydrates and rechecking after 15 minutes until your blood sugar reaches a safe level.
-
Eat a meal or snack: Once your blood sugar is back within the target range, eat a meal or snack containing protein and complex carbohydrates to help stabilize your blood sugar and prevent another drop. Good options include:
- Whole-wheat crackers with cheese
- Peanut butter sandwich on whole-grain bread
- Yogurt with fruit and granola
In severe cases of hypoglycemia, where the individual is unable to swallow or is unconscious, a glucagon injection may be necessary. Glucagon is a hormone that stimulates the release of glucose from the liver and can quickly raise blood sugar levels. Family members and caregivers of individuals at risk for severe hypoglycemia should be trained on how to administer glucagon.
