Hyperbaric Oxygen Therapy for Diabetic Foot Ulcers in Sub-Saharan Africa: A Critical Review of Clinical Evidence, Health-System Feasibility and Public Health Implications.
Diabetic foot ulcers are a serious complication of diabetes that can lead to infection and amputation if not treated properly. Hyperbaric oxygen therapy (HBOT) involves breathing pure oxygen in a pressurized chamber, which may help wounds heal by increasing oxygen delivery to tissues. This review examined studies on HBOT for diabetic foot ulcers in sub-Saharan Africa, where the burden of diabetes is high and resources are limited. The researchers looked at clinical evidence, health-system feasibility, and public health implications. They found that while HBOT shows promise in improving healing rates (some studies reporting over 80% healing), the evidence is limited and of low quality, with few randomized controlled trials. They also noted significant challenges in implementing HBOT in this region, including high costs, lack of equipment, and trained personnel. The review highlights the need for more robust research and careful consideration of feasibility before widespread adoption. For patients, this means that HBOT is not a guaranteed cure, but it may be an option in certain settings, and its use should be discussed with a healthcare provider.
Key takeaways
- HBOT may improve healing of diabetic foot ulcers by delivering more oxygen to the wound, potentially reducing amputation risk.
- Evidence for HBOT in sub-Saharan Africa is limited and low quality; more randomized trials are needed.
- Implementation challenges include high cost, equipment scarcity, and lack of trained staff in many regions.
- Patients should ask their doctor if HBOT is appropriate for their wound and what the expected benefits and risks are.
- HBOT is not a substitute for standard care like infection control and proper wound dressing; it's an add-on therapy.

Editor's note
Think of hyperbaric oxygen therapy like giving your wound a supercharged oxygen boost—it's like opening up a highway for oxygen to reach the healing cells, especially when blood flow is poor. If you've been told that your wound may never heal or that amputation is the only option, this research suggests that oxygen therapy might tip the balance in your favor, helping some stubborn wounds to finally close. In China, specialist diabetic foot centers do offer HBOT as part of a comprehensive treatment package, but it's not a magic bullet—it's used alongside other proven methods like surgical debridement, infection control, and offloading. For you as an international patient, this means that in China you have access to a full range of advanced treatments, including HBOT, which might not be available in your home country. It's worth asking the specialist team straight out: 'Could hyperbaric oxygen help my wound, and what is your protocol for using it?' They will be able to tell you if it's a good fit for your particular situation.
