14 Clues Your Body Might Be Struggling With High Blood Sugar

11. Darkened Skin Areas: The Insulin Resistance Indicator

Darkened areas of skin, particularly around the neck, armpits, and groin, can be an indicator of insulin resistance, a precursor to elevated blood sugar levels. This condition, known as acanthosis nigricans, results from high insulin levels stimulating skin cells to reproduce more rapidly. While these skin changes are not harmful in themselves, they can serve as a visual cue to investigate blood sugar levels and address insulin resistance before it progresses to more serious conditions.

12. Headaches: The Vascular Response

Headaches can be a common occurrence, but when they become frequent or severe, they may be linked to elevated blood sugar levels. High glucose levels can cause fluctuations in blood pressure and blood vessel function, leading to headaches. Additionally, dehydration resulting from frequent urination can contribute to headache development. Recognizing headaches as a potential sign of elevated blood sugar can prompt further investigation and help identify underlying vascular issues.
