Diabetics have poor healing due to damage to blood vessels and nerves, resulting in poor blood circulation and decreased sensitivity, which complicates the healing process.
In diabetics, the high sugar level progressively damages both small and large blood vessels. This results in arteries that are somewhat clogged, less flexible, and more fragile. The result is that blood circulates poorly to certain areas, particularly the skin and extremities like the feet or legs. Poor circulation also means less oxygen and fewer nutrients, which are essential for the rapid healing of wounds. Without these essential elements delivered properly, tissues struggle to repair themselves, and wounds take longer to heal, sometimes even worsening.
What is collagen? Imagine a kind of natural glue, essential for your skin and tissues, that ensures elasticity, strength, and above all, rapid healing. Unfortunately, in diabetic individuals, the production of this magic protein is seriously slowed down. Why? Because excess sugar in the blood interferes with the specialized cells that produce this collagen. Less collagen produced means slow healing of the skin, resulting in wounds that remain open longer, leading to more complications. The result: even a small cut can become a real problem.
In diabetics, chronic hyperglycemia creates a favorable environment for infections, as bacteria love sugar; it's like their favorite buffet. With plenty of glucose available, these microbes grow faster, making healing more complicated. Additionally, when one is diabetic, immune cells (white blood cells) have a harder time moving and quickly eliminating bacteria. Therefore, a small wound is more likely to become infected, which further slows down the healing process.
Diabetics often develop neuropathy, meaning that their nerves gradually lose sensitivity. As a result, when an injury occurs, they may not even feel it. A small wound can linger for a long time without them realizing it, which further slows down the healing process. Less pain felt means less quick reaction, less immediate care, and a healing process that struggles to start properly.
The high blood sugar level (hyperglycemia) promotes a constant inflammatory state, a kind of alarm that is always activated by the body. This chronic inflammation hinders the normal healing of tissues. Essentially, your body detects this situation as a persistent threat and continuously releases inflammatory substances that prevent proper healing. This inflammatory environment slows down cellular repair and hinders an effective immune response. As a result, the wound struggles to close properly and quickly.
Among diabetic individuals, even a small cut or wound on the feet requires special attention. Indeed, peripheral neuropathy affecting the sensory nerves can temporarily mask pain, thereby delaying treatment.
Chronic diabetes often leads to a reduction in collagen production, an essential protein that allows tissues to regenerate effectively during the healing process.
Circulatory disorders caused by diabetes can affect the capillaries, the small blood vessels where the exchange of oxygen and nutrients takes place. These disorders are one of the main reasons why wounds heal slowly in diabetics.
Chronic hyperglycemia leads to a permanent inflammatory state in the body, which affects the body's natural immune response and slows down the overall healing process.
A diabetic should seek medical attention as soon as possible if a wound, even a small one, does not heal or worsens after a few days, or if there are signs of infection such as swelling, redness, discharge, or unusual pain.
Maintaining controlled blood sugar levels, ensuring rigorous hygiene, regularly inspecting the skin for injuries, and promptly consulting a doctor in case of even minor injuries are the best ways to prevent complications related to healing in the case of diabetes.
Diabetic neuropathy reduces nerve sensitivity, preventing affected individuals from fully feeling pain and injuries. This often leads to undetected injuries in their early stages, which can worsen and diminish the body's natural healing ability.
A balanced diet, rich in proteins, vitamins (notably A, C, E), and essential minerals (zinc, copper), helps to enhance the tissue reconstruction process, which is essential for faster and more effective healing in diabetics.
Persistent redness, swelling around the wound, ongoing pain, a foul odor, or unusual discharge are often the first signs of abnormal healing in a diabetic person. If any of these signs appear, it is advisable to consult a healthcare professional promptly.
