When the skin shows the following five signs, it may indicate that blood sugar is out of control:
Persistent skin itching, especially in private areas, may be due to high blood sugar causing microcirculation disorders, slowing down the skin healing process.
Skin becomes unusually dry, accompanied by peeling and cracking, which may be due to high blood sugar levels interfering with the skin's natural moisturizing ability.
Because the immune function of diabetes patients may be affected, skin infections such as folliculitis, cellulitis, or paronychia may be more difficult to control.
The appearance of brown patches on the legs may be skin pigmentation, a skin lesion caused by diabetes known as diabetic dermopathy.
The appearance of spider veins or telangiectasia on the legs may be due to vascular lesions caused by diabetes, affecting the skin's microvessels.
