Feeling Shaky and Anxious? It Could Be Your Blood Sugar

04 Sep 2025 by Ramona S. DeJesus, M.D.

Feeling Shaky and Anxious? It Could Be Your Blood Sugar

Feeling shaky, anxious, or lightheaded? While stress and anxiety are common culprits, your blood sugar levels might be playing a larger role than you think. These symptoms are frequently early warning signs of fluctuating blood sugar, whether it's too high or too low. Understanding this connection is the first step toward regaining control and feeling your best. Let's explore why this happens and what you can do about it.

Understanding the Connection: Blood Sugar & Your Body

Your body relies on glucose (sugar) for energy. When you eat, your body breaks down carbohydrates into glucose, which enters your bloodstream. Insulin, a hormone produced by your pancreas, helps glucose move from your blood into your cells to be used for fuel. When this system isn’t working optimally, blood sugar levels can swing wildly, triggering a cascade of uncomfortable and sometimes alarming symptoms.

Low Blood Sugar (Hypoglycemia): A Common Cause of Anxiety & Shakiness

Low blood sugar, or hypoglycemia, occurs when your blood glucose levels drop below the normal range. This can happen for various reasons, including skipping meals, taking too much insulin (for those with diabetes), or engaging in intense exercise without proper fueling. The body responds to this sudden drop by releasing adrenaline, which can cause:

  • Shakiness: Adrenaline triggers muscle tremors.
  • Anxiety and Irritability: A sudden drop in blood sugar can mimic the physiological responses associated with anxiety.
  • Lightheadedness: Reduced glucose supply to the brain can lead to dizziness.
  • Sweating: A rush of adrenaline can cause your body to sweat.
  • Rapid Heartbeat: Your heart may race to compensate for the low glucose.

What to Do: If you suspect low blood sugar, consume 15 grams of fast-acting carbohydrates (like juice, glucose tablets, or hard candy). Recheck your blood sugar after 15 minutes and repeat if necessary. How To Stabilize Blood Sugar All Day And Avoid The Energy Crash

High Blood Sugar (Hyperglycemia): Another Potential Trigger

While low blood sugar is often the immediate suspect, high blood sugar (hyperglycemia) can also contribute to anxiety and shakiness. Chronically elevated blood sugar can damage nerves and blood vessels, leading to a range of symptoms. Though the immediate effects might not be as pronounced as with hypoglycemia, the long-term consequences of uncontrolled high blood sugar are serious.

7 Surprising Factors Affecting Blood Sugar Levels (Beyond Diet)

You might be meticulously tracking your diet and exercise, but external factors can significantly impact your blood sugar. Here are some surprises:

  • Sleep Quality: Lack of sleep disrupts hormone balance, increasing cortisol levels and reducing insulin sensitivity.
  • Daily Stress: Stress hormones like cortisol can trigger the release of glucose into your bloodstream.
  • Hydration Status: Dehydration can concentrate blood sugar levels.
  • Hormonal Shifts: Fluctuations in hormones (particularly in women) can influence glucose metabolism.
  • Medications: Certain medications can impact blood sugar levels.
  • Illness: When you're sick, your body releases hormones that can raise blood sugar.
  • Weather: Extreme temperatures can affect insulin sensitivity.

Decoding Your Blood Sugar Reading: What the Numbers Mean

Understanding what your blood sugar readings signify is essential for managing your health. Here’s a general guide:

  • Fasting (Before Meal): 70-100 mg/dL
  • 2 Hours After Meal: Less than 140 mg/dL
  • Before Bed: 80-120 mg/dL

Consistent readings outside these ranges warrant a discussion with your doctor.

Blood Sugar Management for Beginners: Simple Steps

  • Eat Regularly: Don't skip meals.
  • Choose Whole Foods: Focus on unprocessed foods.
  • Stay Hydrated: Drink plenty of water.
  • Exercise Regularly: Aim for at least 30 minutes of moderate activity most days of the week.
  • Manage Stress: Practice relaxation techniques like yoga or meditation.
  • Monitor Your Blood Sugar: If you have diabetes or pre-diabetes, regularly check your blood sugar levels.

When to See a Doctor

If you experience persistent anxiety, shakiness, or lightheadedness, and suspect your blood sugar may be involved, consult a healthcare professional. They can accurately diagnose the cause of your symptoms and recommend appropriate treatment. This is particularly important if you have diabetes or are at risk for developing the condition.
