Introduction
Every cell produces energy through oxidation — but when free radicals outnumber antioxidants, damage occurs. This oxidative stress is a key trigger for the fibrosis seen in Dupuytren’s contracture.
The Science Behind the Damage
Free radicals attack cell membranes and DNA, forcing fibroblasts into a constant “repair” mode. Over time, this creates scar-like tissue that contracts and stiffens. In Dupuytren’s, oxidative markers and low glutathione levels are common findings in tissue samples.
Research Findings
A study in Redox Biology found that fibroblasts from Dupuytren’s palms generate excess reactive oxygen species (ROS). When researchers added antioxidants, collagen production and fibroblast activation dropped significantly — suggesting oxidative stress is not just a byproduct but a driver of the disease.
Common Sources of Oxidative Stress
Smoking and alcohol
Chronic inflammation and poor diet
Environmental toxins and pesticides
Uncontrolled diabetes or metabolic dysfunction
Mitochondrial impairment from aging
Protective Strategies
Increase antioxidants (vitamin C, E, N-acetylcysteine, CoQ10).
Eat colorful produce and omega-3 fats.
Stay physically active to boost mitochondrial function.
Avoid processed oils and refined sugars.
Future Directions
Therapies that restore redox balance — including glutathione infusions, NAC supplementation, and mitochondrial nutrients — are being investigated as adjunct treatments for fibrosis. While research is ongoing, lifestyle interventions already offer a safe way to reduce damage.
Conclusion
Free radicals may be tiny, but their impact on connective tissue is massive. Protecting the body from oxidative stress is one of the most effective steps you can take to slow Dupuytren’s progression and support overall healing.
