Modern Technology is Revolutionizing Diabetic Foot Ulcer Treatment
Peripheral Neuropathy is a condition where nerves are damaged, often leading to a loss of sensation in the feet and hands.

CHENNAI: Diabetic Foot Ulcers (DFUs) remain one of the most common and serious complications of diabetes, affecting millions of people worldwide.
The primary causes of DFUs include poor blood sugar control, calluses, foot deformities, inadequate foot care, ill-fitting shoes, peripheral neuropathy, poor circulation, and dry skin. Among these, Peripheral Neuropathy alone is responsible for nearly 50% of DFU cases.
Peripheral Neuropathy is a condition where nerves are damaged, often leading to a loss of sensation in the feet and hands. This reduced sensitivity means that even minor injuries like cuts, blisters, or ulcers can go unnoticed, often worsening over time and risking infection. Diabetic patients are also prone to severe atherosclerosis in the blood vessels of their legs and feet. This restricts blood flow, hampering wound healing and increasing the chance of infections.
The combination of neuropathy and poor circulation can lead to severe outcomes, such as gangrene. While foot ulcers are open wounds that can become infected and difficult to heal, gangrene signifies tissue death due to insufficient blood flow. In extreme cases, gangrene may necessitate amputation of the affected foot or leg.
For diabetic patients, recognizing the early signs of Peripheral Neuropathy is crucial. Symptoms like numbness, tingling, burning pain, heightened sensitivity to touch, pain when walking, and a "sock-like" sensation around the feet should never be ignored. I always advise my patients to examine their feet daily for any signs of changes or abnormalities.
Fortunately, advancements in medical technology have made diagnosing and treating DFUs more precise and effective. Early detection of neuropathy can prevent further complications. Diagnostic tools like biothesiometry gauge the severity of neuropathy, while Doppler tests evaluate the impact of diabetes on arteries and veins. Gait analysis, another valuable diagnostic tool, examines walking patterns to identify abnormalities that contribute to DFUs. By assessing gait data, we can design custom footwear to support the feet and lower the risk of recurring ulcers.
Treatment options have also progressed significantly. Hyperbaric Oxygen Therapy (HBOT), for example, uses pressurized oxygen to speed up the healing of chronic wounds. Additionally, 3D bioprinting is transforming care by creating custom tissue from a patient’s own cells, effectively restoring damaged areas. Cold Atmospheric Plasma (CAP) therapy, another innovative solution, reduces bacterial loads and accelerates healing in chronic DFUs.
Diabetic foot ulcers are preventable and treatable. Thanks to modern technology, we now have the tools to save limbs and reduce amputation rates, ensuring a better quality of life for diabetic patients. Together, we can make diabetic foot complications a thing of the past.
