High Blood Sugar (Hyperglycemia): 10 Warning Signs

Elevated blood glucose produces these signs:

1. Polydipsia: Unquenchable thirst (osmotic diuresis → dehydration).
2. Polyuria: Frequent urination (glucose spills into urine).
3. Blurred Vision: Lens swelling from glucose influx.
4. Fatigue/Weakness: Cellular energy deficit despite high glucose (insulin resistance).
5. Polyphagia: Increased hunger (cells "starving" without insulin).
6. Slow Healing: Impaired immunity, vascular dysfunction.
7. Unintentional Weight Loss: Catabolism of fat/muscle (insulin deficiency).
8. Paresthesias: Tingling/numbness (diabetic neuropathy).
9. Recurrent Headaches.
10. Skin Changes: Dryness, fungal infections, acanthosis nigricans.

Note: Asymptomatic hyperglycemia is common. Regular monitoring + medical management prevent complications.
