Diabetic foot: definitions, context, and key figures in 2025
Diabetic foot, a feared complication of diabetes, appears when deficient glycemic control permanently alters the nerve and vascular structures of the feet. In 2025, about 10% of the French population is affected by diabetes, a steadily increasing figure highlighting the crucial importance of awareness.
Peripheral neuropathy and lower limb arteropathy play a fundamental role in this phenomenon. According to the latest data, up to 20% of diabetic people will develop a foot disorder during their lifetime, while nearly 15,000 amputations related to these complications are still counted each year in France. Appropriate management could avoid up to 85% of these amputations.
The consequences of diabetic foot go beyond simple pain: patients face severe infections, chronic ulcers, and deformities, significantly impacting their quality of life. Specialized networks, including OrthoFrance and Bioskin, illustrate advances in multidisciplinary support, while learned societies such as Diabète et Santé emphasize active prevention.
One of the major challenges remains the dissemination of clear information to patients. As a recent consultation highlights, “a good diagnosis always starts with good listening.” This phrase illustrates the importance of communication between patients and professionals to identify early signs and avoid serious complications.

| Inappropriate shoes | 40-50% | Injuries, corns, plantar ulcer |
The biological mechanisms behind diabetic foot
At the heart of diabetic foot, two pathological mechanisms intertwine to weaken the lower limbs: peripheral neuropathy and obliterative arteropathy of the lower limbs. Understanding these processes highlights the importance of constant vigilance.
Neuropathy results from prolonged hyperglycemia that damages nerve fibers, particularly those responsible for sensation in the feet. This manifests as a decreased ability to detect pain, temperature, and touch. This sensory deficit is often the first step before the appearance of ulcers or infections because the patient does not feel injuries, which delays their management.
At the same time, diabetic arteropathy manifests as a progressive narrowing of the arteries supplying the feet. This phenomenon reduces local blood circulation, slowing wound healing and increasing the risk of necrosis. This circulatory deficiency can also be expressed by muscle cramps and a persistent cold sensation in the extremities.
These two disorders are often exacerbated by aggravating factors linked to lifestyle. Smoking, for example, increases vascular deterioration. Inappropriate footwear can cause friction or excessive pressure, promoting skin lesions. Dryness and cracks due to poor natural foot hydration create an entry point for infections.
- 🩸 Neuropathy: loss of sensation, tingling, unexplained pain
- ❄️ Arteropathy: cold feet, paleness, walking cramps
- 🔥 Aggravating factors: tobacco, poorly fitting shoes, neglect of care
- 💪 Consequences: ulcers, infections, plantar ulcer, bone deformities
| Medical mechanism | Typical symptoms | Main risks |
|---|---|---|
| Diabetic neuropathy | Loss of sensation, tingling, numbness | Ulcers, infections, plantar ulcers |
| Arteropathy | Cold feet, paleness, walking cramps | Poor healing, gangrene, amputation |
In 2025, products such as La Roche-Posay offer moisturizing creams specially designed to counter plantar dryness. Laboratoires Urgo and PodiExpert offer adapted care for healing and protection of fragile areas, while Bayer develops treatments aimed at improving blood circulation. This synergy between pharmaceutical innovations and good practices highlights the positive evolution in care management.
Main warning signs and symptoms not to ignore in diabetic foot
Vigilance regarding the first symptoms of diabetic foot is essential, as their early detection conditions the success of care and the prevention of major complications. Paradoxically, the loss of sensitivity due to neuropathy makes patients less aware of lesions at the start, increasing the risk.
The most frequent warning signs include persistent tingling, numbness, or unusual prickling sensations, and sometimes unexplained pain. Excessive skin dryness associated with cracks can quickly progress to open fissures, entry points for bacterial or fungal infections.
Bone deformities, such as claw toes or collapse of the plantar arch, are indicators of advanced fragility. The presence of corns, hyperkeratosis, or thickened areas should also alert, especially if they persist despite care.
To ensure the good condition of the feet, several simple examinations can be carried out by healthcare professionals, including the use of the monofilament to test sensitivity or palpation of peripheral pulses to check circulation. These tests are essential to assess risk and determine the frequency of podiatric follow-up.
- 👣 Numbness, tingling: first sensory signs to monitor
- 🩹 Cracks, fissures: wounds to treat quickly to avoid infection
- 🦶 Progressive deformities: claw toes, plantar collapse
- 🔍 Sensitivity tests: monofilament and pulse palpation
| Observed symptom | Interpretation | Recommended action |
|---|---|---|
| Loss of sensitivity | Developing neuropathy | Podiatrist consultation, regular monitoring |
| Slow healing | Probable vascular disorder | Vascular assessment, rapid management |
| Persistent deformities or corns | Mechanical overload or neuropathy | Orthoses, adapted shoes |
| Pain when walking | Ischemia, arteropathy | Urgent consultation, thorough examinations |
Practical care and innovations for diabetic foot management
Managing diabetic foot requires a comprehensive approach combining local care, regular monitoring, and therapeutic adaptations. The goal is to prevent minor lesions from evolving into severe complications. Speed of intervention is fundamental.
Daily careful cleaning of the feet with lukewarm water and mild soap, followed by gentle drying, limits infectious risks. Regular application of specialized moisturizing creams, sometimes offered by recognized brands like La Roche-Posay or PodiExpert, helps maintain supple skin protected against cracks.
Wearing adapted and comfortable shoes is another essential key. Specialists recommend soft models, without internal seams, and perfectly fitted – such as those offered by the Scholl brand or technical insoles from Sidas to reduce pressure points. Inspecting the inside of shoes before each use helps detect any foreign body that might cause injury.
In case of more severe lesions, advanced dressings provided by Laboratoires Urgo protect wounds and promote healing. In some cases, the use of specific orthoses, like those designed by Epitact, helps redistribute pressure and correct deformities.
- 🧼 Daily cleaning: gentle essential oils and hypoallergenic soaps
- 🧴 Regular hydration: creams adapted for sensitive and dry skin
- 👟 Adapted shoes: technical insoles, absence of internal seams
- 🩹 Dressings and medical devices: advanced healing and optimal protection
| Care or device | Recommended frequency | Main advantage |
|---|---|---|
| Visual foot inspection | Daily | Early detection of abnormalities |
| Podiatrist consultation | 1 to 6 times/year depending on risk | Prevention and specialized treatment |
| Plantar hydration | Daily | Prevention of cracks and fissures |
| Shoe replacement | According to wear or discomfort | Reduction of pressure points |
