Diabetic foot is a serious condition associated with neuropathy, impaired circulation, infection, and delayed wound healing. Ozone therapy has been investigated as a complementary approach that may support standard diabetic foot care, particularly in local wound management and tissue oxygenation.

Key Points
- Diabetic foot requires urgent and structured medical care, including glucose control, wound care, infection management, and vascular assessment.
- Ozone therapy does not replace standard diabetic foot treatment; it may only be considered as adjunctive support in selected patients.
- Any wound, infection, color change, or circulatory problem in a person with diabetes should be evaluated by a physician.
What Is Diabetic Foot?
Diabetic foot develops when neuropathy, impaired circulation, infection, and repeated trauma contribute to chronic wounds and tissue damage. It is a major cause of preventable complications in people with diabetes.
Loss of sensation may cause small injuries to go unnoticed, while reduced blood flow and high blood glucose levels may delay tissue repair. For this reason, diabetic foot requires early recognition, regular monitoring, and coordinated medical care.
Treatment Challenges
Diabetic foot management is often complex because several factors may act together and delay healing.
- Poor circulation and reduced tissue oxygenation
- Peripheral neuropathy and loss of protective sensation
- Chronic infection or high microbial burden
- High blood glucose and metabolic imbalance
- Repeated trauma, pressure, or inadequate off-loading
- Delayed medical evaluation or insufficient wound care
When to seek care: Any wound, redness, swelling, discharge, odor, black discoloration, pain, fever, or sudden change in a diabetic foot should be evaluated promptly by a healthcare professional.
The Role of Ozone Therapy
Ozone therapy has been studied for potential supportive effects in local microbial control, wound environment regulation, microcirculation, and tissue oxygen utilization.
In diabetic foot care, ozone therapy should be considered only as an adjunct to standard treatment. It does not replace glucose control, antibiotics when indicated, debridement, vascular evaluation, pressure off-loading, or surgical treatment when necessary.
Claims regarding insulin secretion, blood sugar control, or wound closure should be interpreted cautiously and should not replace standard diabetes management.

Application Methods
Local ozone bagging: A controlled ozone-oxygen mixture may be applied to the affected area using a sealed bag in selected wound care protocols.
Ozonated water or oil: These may be used as part of cleansing or dressing protocols when clinically appropriate.
Major autohemotherapy: May be evaluated as systemic support by a physician in selected patients.
Combined wound care: Ozone-based approaches may be considered together with debridement, infection control, dressings, off-loading, vascular assessment, and diabetes management.
Note: The method, dose, frequency, and duration must be determined by a physician. Diabetic foot wounds should not be treated at home without professional supervision.
Potential Supportive Effects
-
May support the local wound environment in selected patients.
-
May contribute to microbial burden management as part of a broader wound care plan.
-
May support tissue oxygen utilization and microcirculation.
-
May be evaluated as adjunctive care in chronic diabetic foot wounds.
-
May support standard wound care protocols when used under physician supervision.
These potential effects may vary depending on wound severity, vascular status, blood glucose control, infection burden, and the patient’s general health condition.
Scientific Evidence
Clinical studies have evaluated ozone therapy in diabetic foot ulcers, with some reporting supportive effects on wound healing parameters. However, study designs, application methods, ozone concentrations, wound types, and follow-up periods vary.
For this reason, ozone therapy should not be described as a guaranteed treatment for diabetic foot. Standard diabetes care, vascular assessment, infection control, pressure off-loading, and structured wound care remain essential.
Further high-quality clinical studies are needed to define patient selection, protocol standards, and expected outcomes more clearly.
