“Too much sugar in your body” is often used in viral headlines, but medically it usually refers to high blood glucose, especially in Type 2 diabetes or prediabetes. The signs are often gradual and easy to miss.
Here are 8 common warning signs of persistently high blood sugar:
1. Frequent urination
Your kidneys try to remove excess glucose through urine, making you pee more often (especially at night).
2. Excess thirst
Because you lose more fluid through urination, your body becomes dehydrated and you feel very thirsty.
3. Increased hunger
Cells can’t use glucose properly, so your body signals hunger even after eating.
4. Fatigue
When sugar can’t enter cells efficiently, your body lacks energy despite high blood sugar levels.
5. Blurry vision
High glucose can change fluid balance in the eyes, affecting focus.
6. Slow healing cuts or wounds
High blood sugar can damage blood vessels and reduce circulation, slowing recovery.
7. Frequent infections
Especially skin, gum, or urinary tract infections due to reduced immune response.
8. Tingling or numbness in hands/feet
Long-term high sugar can damage nerves (diabetic neuropathy).
