8 Possible Signs of High Blood Sugar
1. Excessive thirst
When blood sugar is high, your kidneys try to remove excess glucose through urine, leading to dehydration and increased thirst.
2. Frequent urination
You may find yourself urinating more often, especially at night.
3. Increased hunger
Even after eating, cells may not be getting glucose efficiently, which can trigger hunger.
4. Fatigue
High blood sugar can leave you feeling tired, sluggish, or lacking energy.
5. Blurred vision
Changes in fluid balance can temporarily affect the lenses of your eyes.
6. Slow-healing cuts or wounds
Persistently elevated blood sugar can impair healing and increase infection risk.
7. Frequent infections
Some people experience recurrent skin, urinary, or fungal infections.
8. Tingling or numbness in hands and feet
Over time, high blood sugar can damage nerves, a complication known as diabetic neuropathy.
Important: These Symptoms Aren’t Specific
These signs can also occur with many other conditions. The only way to know whether high blood sugar is the cause is through testing.
Conditions associated with chronically elevated blood sugar include:
- Prediabetes
- Type 2 Diabetes
What to Do If You’re Concerned
✅ Get tested
Common tests include:
- Fasting blood glucose
- HbA1c (average blood sugar over about 3 months)
- Oral glucose tolerance test
✅ Improve lifestyle habits
- Limit sugary drinks
- Eat more vegetables, whole grains, and lean proteins
- Exercise regularly
- Maintain a healthy weight
- Get adequate sleep
✅ See a healthcare professional
Especially if symptoms are persistent or worsening.
When to Seek Prompt Medical Attention
If you have very high blood sugar along with:
- Severe weakness
- Confusion
- Vomiting
- Difficulty breathing
- Extreme dehydration
you should seek urgent medical care.
Bottom Line
The “8 signs” are real symptoms that can be associated with high blood sugar, but they are not proof that you have too much sugar in your body. A blood test is the most reliable way to determine whether your blood sugar is in a healthy range.
