Patient Education Guide
Comprehensive patient guide to understanding chronic wounds including diabetic ulcers, venous leg ulcers, pressure sores, arterial ulcers, and non-healing surgical wounds. Learn about healing stages, why some wounds don't heal, risk factors, and what to expect during treatment.
A chronic wound is any wound that has not healed within the expected timeframe—typically 4 to 12 weeks—despite receiving standard wound care treatment. Unlike acute wounds (cuts, scrapes, or surgical incisions) that heal predictably, chronic wounds become "stuck" in the healing process and may persist for months or even years without proper intervention.
While chronic wounds can be frustrating and challenging, most chronic wounds CAN heal with the right specialized treatment approach. Advanced wound care therapies and regenerative treatments have dramatically improved healing outcomes.
Chronic wounds can develop for various reasons. Understanding the type of wound helps determine the best treatment approach.
Open sores or wounds that develop on the feet of people with diabetes, often due to nerve damage (neuropathy) and poor circulation.
Common causes: Neuropathy, pressure, poor footwear
Risk factors: High blood sugar, smoking, foot deformities
Wounds that occur on the lower legs when veins don't properly return blood to the heart, causing pooling and pressure buildup.
Common causes: Venous insufficiency, varicose veins
Risk factors: Age, obesity, previous blood clots
Wounds caused by prolonged pressure on the skin, typically over bony areas, cutting off blood flow to the tissue.
Common causes: Immobility, friction, moisture
Risk factors: Wheelchair/bedbound, malnutrition
Wounds resulting from poor blood flow (arterial insufficiency), often affecting the feet, ankles, and lower legs.
Common causes: Peripheral artery disease, atherosclerosis
Risk factors: Smoking, diabetes, high cholesterol
Surgical incisions that fail to heal properly, becoming dehiscent (reopening) or developing complications.
Common causes: Infection, poor blood flow, diabetes
Risk factors: Obesity, malnutrition, smoking
Injuries from accidents, burns, or trauma that fail to heal due to tissue damage, infection, or underlying health conditions.
Common causes: Severe tissue damage, burns, crush injuries
Risk factors: Infection, foreign bodies, poor circulation
Unlike a simple cut that scabs over in days, chronic wounds face obstacles that interrupt the natural repair process. Let's examine what goes wrong.
Bacteria in chronic wounds don't float freely—they organize into slimy protective communities called biofilms. Think of it as a fortress wall that shields bacteria from antibiotics, immune cells, and topical treatments. Standard wound care can't penetrate this barrier.
Why it matters: Over 60% of chronic wounds contain biofilm. Even after antibiotic treatment, biofilm regenerates within 24 hours if not physically removed through sharp debridement.
Healing requires a highway of blood vessels delivering oxygen, nutrients, and immune cells to the wound. Diabetes, arterial disease, and chronic venous insufficiency damage this supply line. Without adequate blood flow, tissue starves and healing stalls.
The impact: Diabetic patients with poor circulation face 10-15 times longer healing times. Arterial ulcers with compromised blood flow often require vascular intervention before any wound treatment can succeed.
Normal wounds experience brief inflammation as part of cleanup. Chronic wounds become trapped in endless inflammation—the wound environment floods with destructive enzymes (proteases) that eat away new tissue faster than the body can build it. It's like trying to construct a building while a wrecking crew tears it down.
The science: Matrix metalloproteinases (MMPs) in chronic wounds are 10-50 times higher than normal, actively destroying growth factors and collagen scaffolding needed for healing.
Slough (yellow fibrous tissue) and eschar (black necrotic tissue) cover many chronic wounds like a suffocating blanket. This dead material prevents healthy tissue from growing underneath, harbors bacteria, and hides the true wound depth. The body can't clear this debris on its own in chronic wounds.
Treatment necessity: Wounds with more than 25% necrotic tissue coverage have near-zero chance of healing without aggressive debridement. Removal of this dead tissue is non-negotiable.
Diabetes impairs white blood cell function and damages blood vessels. Autoimmune diseases attack the body's own healing processes. Malnutrition deprives wounds of protein building blocks. Kidney disease creates toxic buildup that inhibits cell growth. These systemic issues sabotage healing from within.
Critical point: You can apply the most advanced wound dressing in the world, but if blood sugar is uncontrolled (HbA1c >9%) or albumin is critically low, the wound won't close. Treating the whole patient is essential.
Every step on a diabetic foot ulcer causes microtrauma that tears newly forming tissue. Pressure sores on bedsores experience constant pressure from body weight crushing fragile blood vessels. Repeated injury—even minor—keeps restarting the healing clock back to day zero.
Offloading imperative: Studies show 90% healing rates with proper pressure relief (CAM boot, special mattress) versus 30% without. Eliminating mechanical stress is often the difference between healing and amputation.
Each chronic wound faces its own combination of obstacles. Healix360's specialists identify and address every barrier systematically with advanced treatments.
Connect With a SpecialistUnderstanding how wounds normally heal helps you recognize when a wound has become chronic and needs specialized care.
Timeline: Seconds to minutes after injury
Blood vessels constrict and platelets form a clot to stop bleeding. This creates a temporary seal and releases growth factors that signal the next phase of healing to begin.
What you see: Bleeding stops, scab forms
Timeline: 1-4 days after injury
White blood cells arrive to fight infection and clear debris. The wound area becomes red, warm, and swollen as immune cells work to clean the wound. This is a normal and necessary part of healing.
What you see: Redness, warmth, swelling, some clear or yellow drainage
Timeline: 4 days to 3 weeks after injury
New tissue (granulation tissue) fills the wound bed. Blood vessels regrow, bringing oxygen and nutrients. New skin cells (epithelial cells) multiply and migrate across the wound surface to close the gap. Collagen fibers form to strengthen the new tissue.
What you see: Pink/red granulation tissue, wound edges pulling together, wound getting smaller
Timeline: 3 weeks to 2 years after injury
The wound continues to strengthen and mature. Collagen fibers reorganize to increase tensile strength. The scar gradually fades and flattens. Even after the wound is closed, it continues to strengthen over many months.
What you see: Wound fully closed, scar tissue forms and gradually lightens in color
Chronic wounds get stuck in the inflammatory phase (Stage 2) and never progress to the rebuilding phase. They remain in a cycle of persistent inflammation and tissue breakdown, preventing new healthy tissue from forming. This is why specialized treatment is needed to "reset" the wound and restart the healing process.
Effective chronic wound treatment addresses the underlying barriers to healing while promoting tissue regeneration. Modern advanced wound care uses a multifaceted approach tailored to each patient's specific wound and medical conditions.
The cornerstone of chronic wound care. Debridement removes dead tissue, biofilm, and bacteria that prevent healing. This "resets" the wound environment and stimulates the growth of healthy new tissue.
Methods: Sharp surgical debridement, enzymatic debridement, biological debridement (medical-grade maggots)
Advanced biological treatments that provide growth factors, proteins, and cellular components to jumpstart healing and rebuild tissue.
Examples: Skin substitutes, amniotic membrane allografts, growth factor therapies, cellular and tissue-based products
Specialized dressings maintain optimal moisture balance, manage drainage, reduce bacterial load, and create the ideal environment for healing.
Types: Hydrocolloids, hydrogels, alginates, foam dressings, antimicrobial dressings, collagen dressings
A vacuum device that applies controlled suction to the wound, removing excess fluid, increasing blood flow, and drawing wound edges together to accelerate healing.
Best for: Large wounds, surgical wounds, wounds with significant drainage
Removing pressure from the wound area is critical. Specialized boots, cushions, wheelchair modifications, and repositioning schedules prevent ongoing trauma.
Essential for: Diabetic foot ulcers, pressure ulcers, heel wounds
Controlling diabetes, improving circulation, optimizing nutrition, and addressing other medical issues that impair healing. This holistic approach is essential for long-term success.
May include: Blood sugar control, compression therapy, vascular interventions, nutritional support
Every chronic wound is unique. Effective treatment requires a personalized approach that addresses your specific wound type, underlying health conditions, lifestyle factors, and healing goals. Our wound care specialists create individualized treatment plans that combine the most effective therapies for your situation.
Understanding the treatment process helps you know what's normal and what to expect on your healing journey.
Complete medical history, wound evaluation, photos, measurements, and vascular assessment
Blood work, wound cultures, or vascular studies to identify underlying issues
Your provider will explain your specific wound issues and outline the recommended treatment approach
Wound cleaning, debridement if needed, application of advanced dressings
Most patients require weekly or bi-weekly visits initially, then less frequently as healing progresses. Each visit typically includes:
Progress Monitoring: Measuring wound size and depth
Debridement: Removing any dead tissue or biofilm
Dressing Changes: Applying appropriate dressings
Adjustments: Modifying treatment based on response
The wound may look worse before it looks better. Debridement removes dead tissue, which can temporarily make the wound appear larger. This is normal and necessary for healing.
You should start seeing healthy pink/red tissue (granulation) filling the wound bed. The wound should begin getting smaller, less deep, and have less drainage.
The wound continues to close from the edges. New skin begins to cover the surface. You may transition to less intensive treatments.
Most chronic wounds achieve complete closure within 3-4 months with proper treatment. Some complex wounds may take longer, but should show steady progress.
Healing rates vary based on wound size, depth, location, and your overall health. Some wounds heal faster, others take longer. The key is consistent progress—your wound should show measurable improvement every 2-4 weeks.
If you notice any warning signs, contact your wound care provider immediately. Early intervention can prevent serious complications like infection or sepsis.
