Their development is the result of numerous internal and external factors, and their mechanism is related to both microcirculation disorders and the effects of toxic metabolic waste products. Here&#039;s a detailed explanation of how these hyperpigmentation forms.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Mechanisms of diabetic discoloration<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">1. Damage to blood vessels and nerves (Microangiopathy)<\/h3>\n\n\n\n<p>Prolonged high blood glucose levels lead to damage to small blood vessels, resulting in reduced blood flow to the skin. This limited supply of oxygen and nutrients to skin cells results in:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>weakening of epidermal regeneration,<\/li>\n\n\n\n<li>increased sensitivity to injuries and infections,<\/li>\n\n\n\n<li>abnormal production of melanin by melanocytes.<\/li>\n<\/ul>\n\n\n\n<p>Additionally, diabetic neuropathy, or nerve damage, disrupts communication between skin cells and the nervous system, which also affects the pigmentation process.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">2. Impact of advanced glycation end products (AGEs)<\/h3>\n\n\n\n<p>Advanced glycation end products (AGEs) are formed as a result of prolonged high blood sugar levels. These toxic compounds:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>accumulate in skin tissues, accelerating the aging process,<\/li>\n\n\n\n<li>damage collagen and elastin fibers, which affects the elasticity of the skin,<\/li>\n\n\n\n<li>stimulate the overproduction of melanin, which leads to the formation of dark pigmentation spots.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">3. Inflammation<\/h3>\n\n\n\n<p>The chronic inflammation associated with diabetes increases the activity of enzymes responsible for melanin synthesis, such as tyrosinase. As a result:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>melanocytes produce larger amounts of pigment,<\/li>\n\n\n\n<li>The skin&#039;s regenerative processes are disturbed, which perpetuates discoloration.<\/li>\n<\/ul>\n\n\n\n<p>Inflammation can also be the result of minor skin injuries, which heal much slower in diabetic patients, contributing to the development of <a href=\"https:\/\/ruedeskin.com\/hiperpigmentacja-jak-pozbyc-sie-przebarwien-ze-skory\/\">hyperpigmentation<\/a> post-inflammatory. You can read more about this in the article: <a href=\"https:\/\/ruedeskin.com\/przebarwienia-pozapalne-przyczyny-jak-je-usunac\/\">Post-inflammatory hyperpigmentation \u2013 causes, how to remove them?<\/a><\/p>\n\n\n\n<h3 class=\"wp-block-heading\">4. Hormonal changes<\/h3>\n\n\n\n<p>Diabetes affects the body&#039;s hormonal balance, which can further activate melanocytes to overproduce melanin. These changes are particularly noticeable in diabetic women who experience hormonal fluctuations during pregnancy, menopause, or when using hormonal contraception.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Location of changes<\/h2>\n\n\n\n<p>Diabetic hyperpigmentation can appear on various areas of the body, and its location is often related to mechanical skin trauma, poor blood flow, or high glucose levels. Typical locations include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Neck:<\/strong> So-called acanthosis nigricans often occurs in this area, characterized by dark brown, thickened spots.<\/li>\n\n\n\n<li><strong>Hands and feet:<\/strong> Discoloration in these areas results from impaired microcirculation.<\/li>\n\n\n\n<li><strong>Knees and elbows:<\/strong> Changes in these areas may result from excessive pressure and friction.<\/li>\n\n\n\n<li><strong>Areas under pressure:<\/strong> For example, under a watch strap, in skin folds or under clothing that causes friction.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Diabetic spots on legs \u2013 how to treat?<\/h2>\n\n\n\n<p><strong>Characteristic:<\/strong> The patches are light to dark brown in color, have sharp edges, and do not cause any discomfort\u2014they do not itch, hurt, or peel. They are more common in patients with long-term diabetes (over 10 years) and poor glycemic control.<\/p>\n\n\n\n<p><strong>Diagnostics:<\/strong> Diagnosis is based on clinical examination and a diabetic history. It should be differentiated from varicose veins, post-traumatic lesions, or melanoma. It is crucial to measure HbA1c levels and assess diabetes control.<\/p>\n\n\n\n<p><strong>Treatment:<\/strong> Optimal glycemic control (HbA1c &lt; 7%) and blood pressure are essential. Local treatments include tretinone creams, chemical peels, or laser therapy. Spots rarely disappear completely but may fade with good metabolic control.<\/p>\n\n\n\n<p><strong>Care:<\/strong> Wash your feet daily with a mild soap, moisturize with cream (avoiding the spaces between your toes), regularly inspect your feet, and protect them from injuries and sun exposure (SPF 30+). Regular diabetes checkups every 3-6 months are essential.<\/p>\n\n\n\n<p><strong>Prognosis:<\/strong> The spots are not life-threatening, but they signal the progression of vascular complications of diabetes. They are an indication for intensified treatment and more frequent medical checkups.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Risk factors for skin lesions in diabetes<\/h2>\n\n\n\n<p>Not every diabetic patient experiences skin discoloration. Factors that increase the risk of developing it include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Unregulated glycemia:<\/strong> The higher the blood sugar level, the greater the risk of vascular damage and inflammatory processes.<\/li>\n\n\n\n<li><strong>Genetic predisposition:<\/strong> Some people are more susceptible to hyperpigmentation due to genetic melanocyte activity.<\/li>\n\n\n\n<li><strong>Exposure to UV radiation:<\/strong> Prolonged exposure to the sun can worsen existing discolorations and initiate new changes.<\/li>\n\n\n\n<li><strong>Comorbidities:<\/strong> Renal failure, insulin resistance or obesity may exacerbate pigmentation changes.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">How to prevent diabetic discoloration?<\/h2>\n\n\n\n<p>Prevention is key to minimizing the risk of discoloration. Here are a few tips:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Daily sun protection:<\/strong> Creams with high <a href=\"https:\/\/ruedeskin.com\/product\/restart-spf-50\/\">SPF (50+)<\/a> protect the skin against UV radiation, which intensifies pigmentation changes.<\/li>\n\n\n\n<li><strong>Regular skin care:<\/strong> Moisturizing and using gentle cleansing products help maintain the skin&#039;s protective barrier.<\/li>\n\n\n\n<li><strong>Avoiding irritants:<\/strong> Mechanical trauma, excessive rubbing or contact with photosensitizing substances may exacerbate the changes.<\/li>\n\n\n\n<li><strong>Healthy lifestyle:<\/strong> A balanced diet rich in antioxidants, regular physical activity and adequate hydration support skin regeneration.<\/li>\n<\/ol>\n\n\n\n<h2 class=\"wp-block-heading\">How to distinguish diabetic hyperpigmentation (diabetic spots) from freckles?<\/h2>\n\n\n\n<p>Not every skin spot is the same \u2013 freckles and discoloration, while they may look similar at first glance, have completely different stories behind them.
