High glucose levels can damage blood vessels and nerves, reducing blood circulation. As a result, the skin may not receive enough nutrients and oxygen, making it susceptible to infections and other diseases.
People with diabetes often have dry skin due to dehydration. The lack of moisture causes patches of skin to peel or crack. Slow wound healing is also common, and even small cuts can become serious if left untreated.
The immune system is also affected by high blood sugar levels.
High blood sugar can lead to a variety of skin conditions that may go unnoticed at first. A common problem is fat necrosis, characterized by shiny, reddish-brown patches often found on the lower legs. These lesions often indicate underlying vascular problems.
Granuloma annulare appears as small, ring-shaped lumps on the skin. They are usually harmless but can be a concern for people with diabetes because they can be related to glucose levels.
Skin tags often appear in areas of friction and are more evident in people with insulin resistance.
Fungal infections such as thrush or yeast infections can thrive when blood sugar levels are high.
A patch of dark or velvety skin on the neck, armpits, groin or elsewhere may be a sign of prediabetes.
