GLP-1 receptor agonists (such as Wegovy and Ozempic), currently dominating the headlines as weight loss medications, have been found to significantly lower the risk of mortality in patients with diabetic foot. A research team from the University of Montpellier in France reached this conclusion after analyzing the health outcomes of 133,791 patients suffering from diabetic foot complications.
Diabetic foot ulcers are among the most dangerous complications of diabetes. Wounds on the feet—caused by poor circulation and peripheral neuropathy (nerve damage)—struggle to heal and are highly susceptible to infection. In severe cases, this leads to amputation.
In South Korea, it is estimated that 5,000 to 6,000 people undergo foot or leg amputations annually. Remarkably, 70–80% of these cases are attributed to diabetic foot ulcers, far outnumbering amputations caused by traffic accidents, industrial trauma, or malignant bone tumors. This data underscores just how life-threatening this complication can be.
Beyond Glucose Management
The study revealed that patients using GLP-1 drugs showed a statistically significant reduction in mortality risk compared to those who did not. Interestingly, the research team noted that this difference cannot be attributed to blood sugar control alone.
GLP-1 drugs trigger a cascade of physiological benefits, including weight loss, systemic inflammation reduction, and improved vascular function. It is likely that these multifaceted effects work together to improve overall survival rates in high-risk patients.
[Frequently Asked Questions]
Q1. Do GLP-1 drugs directly heal diabetic foot ulcers?
A1. No. GLP-1 is not a direct wound-healing agent. Instead, it lowers the risk of death and further complications by improving the patient’s underlying health—specifically by reducing inflammation and improving the health of blood vessels.
Q2. Why is diabetic foot considered so dangerous?
A2. Because of reduced sensation (neuropathy), patients often do not notice when a wound occurs. Combined with poor circulation, healing is incredibly slow. If an infection reaches the bone (osteomyelitis), amputation often becomes inevitable. Critically, the five-year survival rate following a major amputation is lower than that of several types of cancer, making it a fatal turning point for many.
Q3. What is the most important step in preventing diabetic foot?
A3. Daily foot inspections are essential to catch wounds or blisters early. Alongside strict blood sugar management, patients should keep their feet clean and dry, never walk barefoot, and always wear well-fitting shoes to prevent even minor trauma.
