7 Alarming Signs Your Blood Sugar Is Too High
High blood sugar (hyperglycemia) happens when there is too much glucose circulating in the blood. It is commonly associated with diabetes, but it can also occur due to illness, stress, certain medications, or other health conditions.
Some signs can be easy to overlook. Recognizing them early can help prevent complications.
1. Increased thirst
When blood sugar rises, the body tries to remove excess glucose through urine. This can lead to:
- Feeling unusually thirsty
- Drinking more fluids than normal
- Dry mouth
2. Frequent urination
High glucose levels can cause the kidneys to work harder to remove sugar from the blood, leading to:
- Urinating more often
- Waking up at night to urinate
3. Unusual fatigue
When glucose cannot enter cells effectively for energy, you may feel:
- Tired despite resting
- Weak
- Low on energy
4. Blurred vision
High blood sugar can temporarily affect the fluid balance in the eye, causing:
- Blurry vision
- Difficulty focusing
Persistent vision changes should be checked by a healthcare professional.
5. Increased hunger
Even with plenty of glucose in the bloodstream, the body may not be using it properly, leading to:
- Feeling hungry soon after eating
- Increased cravings
6. Slow-healing cuts or frequent infections
High blood sugar can affect immune function and circulation, which may contribute to:
- Cuts taking longer to heal
- Repeated skin, urinary, or yeast infections
7. Tingling or numbness in hands and feet
Over time, high blood sugar can damage nerves, causing:
- Pins-and-needles sensations
- Burning feelings
- Reduced sensation
