20 Silent Signs You May Have Diabetes Without Knowing

4. Constant Hunger

Feeling hungry right after meals? It may mean glucose isn’t reaching your cells properly, triggering more hunger signals.

5. Extreme Fatigue

When your cells can’t use sugar efficiently, energy levels crash. You might feel tired no matter how much you rest.

6. Blurred Vision

High glucose can cause swelling in your eye lenses, leading to blurred or shifting vision.

7. Slow-Healing Wounds

Cuts, scrapes, or bruises that take longer than usual to heal can be a sign of poor blood circulation due to diabetes.

8. Frequent Infections

Diabetes weakens your immune system, making you more vulnerable to skin, urinary tract, or yeast infections.

9. Numbness or Tingling

A tingling or “pins and needles” sensation in your hands or feet can indicate nerve damage (neuropathy) from prolonged high blood sugar.

10. Dark Patches of Skin

Velvety dark spots—especially on the neck, armpits, or groin—are known as acanthosis nigricans and often indicate insulin resistance.
