Be Careful: These 5 Skin Problems Could Be Signs of Diabetes
Diabetes, particularly type 2, often presents itself through various early signs on the skin. Paying attention to these signs can aid in early detection and management of the disease. Here are five skin issues that could indicate diabetes:
1. Dark Patches in Skin Folds (Acanthosis Nigricans)
Darkened patches in skin folds, commonly found around the neck, armpits, or groin, are often a warning sign of insulin resistance, which is closely linked to type 2 diabetes. These patches are usually thick, soft, and may feel slightly velvety to the touch. Although painless, these marks signal a need to check blood sugar levels.
2. Dry and Itchy Skin
Chronic high blood sugar levels can lead to dehydration, making the skin feel dry, cracked, and itchy. Reduced blood circulation due to diabetes can also impair the skin’s ability to retain moisture. Dry, flaky areas are common on the hands, elbows, and feet and may require extra hydration and attention.
3. Slow-Healing Wounds
People with diabetes may notice that small cuts or bruises take longer to heal. Elevated blood sugar levels can delay wound healing by slowing circulation and reducing immune response, increasing infection risk. Any wound that takes an unusually long time to heal, especially on the feet, should be examined by a healthcare provider.
4. Diabetic Dermopathy
Diabetic dermopathy causes light brown or reddish patches to appear, often on the shins. These patches are usually round or oval in shape and resemble age spots. Dermopathy is harmless but can be a visible indication of poor blood sugar control.
5. Yellow, Reddish, or Brown Patches (Necrobiosis Lipoidica)
This skin condition begins as small red bumps that gradually turn into patches of yellow, reddish, or brown. Over time, these areas may become shiny, with a visible blood vessel network, and the skin becomes thin and fragile. Though painless, these marks are often associated with diabetes and should prompt a medical evaluation.
