Most people blame their diabetic wounds not healing on poor blood sugar alone, but there's usually a hidden cause. Constant pressure on the wound reopens it every time you walk. Biofilm—a bacterial shield invisible to the eye—blocks healing. Dry wound edges prevent new skin cells from moving. Using the wrong products slows tissue growth. Not treating the wound consistently leaves gaps in protection. These factors sabotage healing even when blood sugar is controlled. Finding and fixing the real problem—not just blaming diabetes—gets stubborn wounds finally closing.
