Very high blood sugar (called Hyperglycemia) often happens in people with Diabetes when glucose levels rise far above normal. If it remains high for long periods, it can lead to serious complications.
Here are 14 symptoms that may indicate very high blood sugar levels:
1. Frequent urination
Your kidneys try to remove excess sugar from the blood through urine, causing you to urinate more often.
2. Excessive thirst
Because you lose more fluids through urination, your body signals strong thirst.
3. Extreme hunger
Even though there is plenty of sugar in the blood, your cells cannot use it properly, making you feel constantly hungry.
4. Fatigue or weakness
Without proper glucose use, the body lacks energy, leading to tiredness.
5. Blurred vision
High glucose levels can cause the lenses in your eyes to swell, affecting vision.
6. Dry mouth
Dehydration from high blood sugar can lead to a persistent dry mouth.
7. Slow-healing cuts or wounds
High glucose affects circulation and the immune system, slowing healing.
8. Frequent infections
People may experience repeated skin infections, gum infections, or urinary infections.
9. Tingling or numbness in hands and feet
Nerve damage from prolonged high blood sugar (diabetic neuropathy) can cause burning or tingling sensations.
10. Unexplained weight loss
The body may start breaking down fat and muscle for energy when glucose cannot enter cells properly.
11. Headaches
Blood sugar spikes can lead to recurring headaches.
12. Irritability or mood changes
Fluctuating glucose levels can affect mood and concentration.
13. Nausea or stomach pain
Very high sugar levels may cause digestive discomfort.
14. Fruity-smelling breath
This can be a warning sign of Diabetic Ketoacidosis, a dangerous condition that requires urgent medical care.
