16 Sneaky Symptoms That Could Mean Your Blood Sugar Is Too High

11. Skin Darkening (Acanthosis Nigricans)

Acanthosis nigricans is a skin condition commonly associated with insulin resistance and type 2 diabetes. It appears as dark, velvety patches on the neck, armpits, groin, or other folds of the skin. These areas may feel thicker or slightly raised, sometimes accompanied by mild itching. While acanthosis nigricans itself is not harmful, it serves as an early warning sign of underlying metabolic issues, such as prediabetes or obesity-related insulin resistance. Treating the root cause, including lifestyle changes to improve insulin sensitivity, can help reduce the appearance of these patches over time.

12. Irritability and Mood Swings

Fluctuating blood sugar levels can wreak havoc on emotional well-being, leading to mood swings, irritability, and even anxiety. High blood sugar levels can make patients feel agitated or sluggish, while low levels may cause nervousness or confusion. The physical strain of managing diabetes, combined with its symptoms, can further contribute to stress and emotional instability. For many patients, mood swings can strain personal relationships and decrease overall quality of life. Addressing this issue requires a holistic approach, including blood sugar management, stress reduction techniques, and, if necessary, mental health support through therapy or counseling.
