Several measures can help prevent or delay skin breakdown: Having an interface that fits well Maintaining a stable body weight (even small changes in weight can affect fit) Eating a healthy diet and drinking lots of water (to control body weight and maintain healthy skin) For patients with diabetes, monitoring and controlling their blood sugar level (to help prevent vascular disease and thus maintain blood flow to the skin) For patients with a lower-limb prosthesis, maintaining body alignment (eg, wearing only shoes with a similar heel height) However, even with a good fit, problems can occur.
