No wound treatment works well if blood sugar stays high. Elevated glucose sabotages healing through multiple mechanisms simultaneously. It weakens immune cells so they can't fight infection. It damages blood vessels reducing oxygen delivery. It feeds bacteria helping them multiply faster. It interferes with collagen production needed for new tissue. Even the best wound spray can't overcome the damage high blood sugar causes. Getting glucose under control isn't optional—it's the absolute foundation for any wound to heal. Combine good sugar management with proper wound care for success.
