Managing blood sugar is a critical part of living well with type 2 diabetes. While many people can keep their levels balanced with diet, exercise, and medication, it’s not always easy to tell when your blood sugar is slipping out of control. Recognizing the warning signs early can help you avoid serious complications and stay healthier longer. Here’s what to watch for—and when to reach out for help.
1. You’re Not Checking Your Blood Sugar Regularly
One of the most important habits in diabetes management is tracking your blood sugar with a meter. Without regular testing, you won’t have the clear picture your doctor needs to adjust your treatment plan effectively. Keeping a log of your readings lets your healthcare provider see patterns over time and make the best recommendations for your health.
2. You’re Constantly Thirsty and Need to Urinate Often
Feeling parched and running to the bathroom more than usual are classic signs of high blood sugar. When glucose levels rise, your kidneys try to flush the excess sugar from your blood, pulling water from your tissues in the process. This causes increased urination and dehydration, signaling your body to demand more fluids.
3. You’re Always Tired
Fatigue is a common symptom of uncontrolled blood sugar. When glucose stays trapped in your bloodstream and can’t fuel your cells, your muscles lack the energy they need. This can leave you feeling drained, sometimes so much that you need a nap after meals or throughout the day.
4. You Feel Dizzy or Shaky
Dizziness and shakiness can indicate low blood sugar, or hypoglycemia, which can be dangerous if untreated. Since your brain relies on glucose to function, a sudden drop can cause confusion or fainting. Drinking a glass of fruit juice may help raise your blood sugar quickly, but if these symptoms persist, consult your doctor—your medication or diet might need adjustment.
5. Your Hands and Feet Are Swollen
Swelling in your extremities can be a warning sign of kidney problems. High blood pressure combined with diabetes can damage your kidneys over time, impairing their ability to filter fluids and waste. If you notice swelling, it’s important to work closely with your healthcare team to manage your blood sugar and blood pressure.
6. You Experience Numbness or Tingling
Persistent numbness, tingling, or pain in your hands and feet can be signs of diabetic nerve damage, known as peripheral neuropathy. This condition affects sensation and can lead to unnoticed injuries or infections, especially in your feet. Regular foot check-ups with a podiatrist are crucial to prevent complications.
7. You Have Digestive Issues
Diabetes can damage the nerves that control your stomach, causing a condition called gastroparesis. Symptoms include nausea, bloating, heartburn, and a feeling of fullness even if you haven’t eaten much. Gastroparesis makes blood sugar management harder because it affects digestion and food absorption.
8. Your Vision Is Blurring or Changing
High blood sugar and hypertension can harm the delicate blood vessels in your eyes, leading to diabetic retinopathy, a leading cause of blindness in adults. Warning signs include blurred vision, seeing spots, flashing lights, or lines. Early detection through eye exams is essential to protect your sight.
9. You’re Losing Weight Without Trying
Unexpected weight loss might seem like a bonus, but if it’s unintentional, it could mean your blood sugar is dangerously high. Excess glucose spills into urine, taking calories and fluids with it, causing weight loss and dehydration.
10. You Get Frequent Infections
Recurring infections—such as gum disease, urinary tract infections, skin infections, or yeast infections—can be a red flag that your blood sugar isn’t well controlled. High glucose levels impair your immune system, making it harder to fight infections.
11. Cuts and Bruises Are Slow to Heal
If wounds linger and take a long time to heal, this could be a sign that your blood sugar is impacting your body’s ability to repair itself. Even small injuries need attention to prevent infections, which can worsen blood sugar control and create a vicious cycle.
How to Keep Your Blood Sugar in Check
The good news? You can take steps every day to manage your diabetes and reduce complications:
- Follow your doctor’s treatment plan: Take medications as prescribed.
- Monitor your blood sugar: Use a glucose meter regularly.
- Eat a balanced diet: Focus on whole foods, plenty of vegetables, lean proteins, and limited sugars and refined carbs.
- Stay active: Regular exercise helps your body use glucose more effectively.
- Manage your blood pressure: Keep it within target ranges.
- Stay hydrated: Drink plenty of water.
- Keep up with medical appointments: Regular lab tests like the A1C help track your overall control.
When to Call Your Doctor
Don’t hesitate to reach out to your healthcare provider if you experience:
- Severe dizziness or fainting
- Persistent numbness or tingling
- Blurred or double vision
- Uncontrolled vomiting
- Difficulty managing blood pressure
Early intervention can make all the difference.
In Summary: Recognizing the signs of uncontrolled blood sugar is vital in managing diabetes. From frequent thirst and fatigue to slow-healing wounds and vision changes, these symptoms signal that your body needs attention. Stay proactive with testing, healthy habits, and regular medical care to keep your blood sugar—and your health—in balance.
