Foot health is an important part of overall well-being, especially for people living with diabetes.

Understanding diabetic foot, recognizing early warning signs, and practicing regular foot care may help support long-term foot health. This article provides general educational information about diabetic foot. It is not a substitute for professional medical advice, diagnosis, or treatment. What Is Diabetic Foot? Diabetic foot is a general term used to describe a range of foot problems that may occur in individuals with diabetes. These problems can involve the skin, nerves, blood vessels, joints, and soft tissues of the feet. Not everyone with diabetes develops diabetic foot complications. However, maintaining good diabetes management and consistent foot care may help reduce potential risks. Common Symptoms of Diabetic Foot Symptoms may vary from person to person depending on the underlying condition and its severity. Common symptoms may include: Numbness or reduced sensation in the feet Tingling or burning sensations Dry or cracked skin Corns or calluses Swelling of the foot or ankle Changes in skin color Slow-healing cuts or blisters Foot pain in some individuals Changes in foot shape over time Difficulty noticing minor injuries due to reduced sensation These symptoms can also occur for reasons unrelated to diabetes. A healthcare professional can evaluate their cause. Possible Causes Several factors may contribute to diabetic foot problems, including: Reduced Nerve Function Long-term elevated blood glucose levels may affect nerves, reducing the ability to feel pain, heat, or injury. Reduced Blood Flow Changes in circulation may decrease blood supply to the feet, which can affect normal tissue health. Minor Foot Injuries Small cuts, blisters, or pressure points may go unnoticed when foot sensation is reduced. Foot Deformities Structural changes in the foot may increase pressure on certain areas, making skin problems more likely. Improper Footwear Shoes that do not fit well may create friction or pressure that can contribute to foot irritation. Risk Factors Certain factors may increase the likelihood of diabetic foot problems, including: Long-standing diabetes Reduced sensation in the feet Previous foot ulcers Poorly fitting footwear Smoking Reduced circulation Existing foot deformities Limited foot care Difficulty inspecting the feet regularly Having one or more risk factors does not necessarily mean complications will occur. Possible Complications If foot problems are not identified and managed appropriately, complications may develop in some individuals. Possible complications include: Skin infections Foot ulcers Tissue damage Changes in walking ability Bone or joint involvement in some cases The likelihood of complications varies widely among individuals. How Is Diabetic Foot Diagnosed? Healthcare professionals may assess foot health through several methods, including: Reviewing medical history Physical examination of the feet Checking skin condition Evaluating circulation Testing sensation Assessing footwear Imaging studies when clinically appropriate Laboratory testing if indicated The diagnostic approach depends on each person's symptoms and overall health. General Foot Care Tips Healthy foot care habits may help support foot health. These general practices include: Inspect your feet daily. Wash feet with mild soap and lukewarm water. Dry carefully, especially between the toes. Apply moisturizer to dry skin, avoiding between the toes unless advised otherwise. Trim toenails carefully. Wear clean socks.
