How to Identify and Treat Hypergranulation Tissue

Wound healing is a complex biological process that involves several stages, including hemostasis, inflammation, proliferation, and remodeling. Each stage plays a crucial role in restoring tissue integrity and function.

Introduction to Hypergranulation Tissue:

Hypergranulation tissue, also known as proud flesh, is a common complication that can occur during the wound healing process. It manifests as an excessive growth of granulation tissue beyond the wound margins, often protruding above the skin surface. This abnormal tissue growth can impede the normal healing process and lead to delayed wound closure. In some cases, hypergranulation tissue may also be accompanied by inflammation and infection, further complicating the healing process. Identifying and effectively treating hypergranulation tissue is essential for promoting optimal wound healing and preventing potential complications.

What Is Hypergranulation Tissue?

A. Definition and Characteristics of Hypergranulation Tissue:

Hypergranulation tissue, also known as overgranulation or proud flesh, is an excessive formation of granulation tissue that protrudes above the wound surface. It appears as a raised, beefy red or pinkish tissue with a shiny, moist surface. Hypergranulation tissue can impede the normal wound healing process, leading to delayed wound closure and increased risk of infection.

B. Visual Identification of Hypergranulation Tissue:

Visual identification of hypergranulation tissue can be done by observing the wound bed. Hypergranulation tissue typically presents as a raised, rounded mass that extends beyond the wound edges. It has a distinct appearance, often resembling raw, beefy tissue with a shiny or wet surface. Additionally, hypergranulation tissue may bleed easily upon contact and can be painful to the touch.

C. Differentiating Hypergranulation Tissue from Other Wound Types:

Hypergranulation tissue can be differentiated from other wound types based on appearance and location. Unlike healthy granulation tissue, flush with the wound surface, hypergranulation tissue protrudes above the wound bed. It may also exhibit a shiny, moist surface, in contrast to the dry appearance of necrotic tissue. Additionally, hypergranulation tissue is typically located at the edges of the wound and may extend beyond the wound margins. Proper identification of hypergranulation tissue is essential for implementing appropriate treatment strategies to facilitate wound healing.

What is The Cause of Hypergranulation?

A. Underlying Causes and Contributing Factors:

Hypergranulation tissue can result from various underlying causes and contributing factors, including:

Excessive Moisture: Prolonged exposure to moisture, such as wound exudate or urine, can contribute to the development of hypergranulation tissue by disrupting the normal wound healing process.

Infection: Bacterial or fungal infections within the wound can trigger an inflammatory response, leading to the formation of hypergranulation tissue.

Foreign Bodies: The presence of foreign bodies or debris within the wound can stimulate an exaggerated granulation tissue response, resulting in hypergranulation tissue formation.

Poor Wound Care Practices: Improper wound care techniques, such as using occlusive dressings or applying excessive pressure, can disrupt the delicate balance of wound healing and promote the development of hypergranulation tissue.

Underlying Health Conditions: Certain medical conditions, such as diabetes, peripheral vascular disease, or compromised immune function, can impair the body's ability to heal wounds properly, increasing the risk of hypergranulation tissue formation.

B. Common Medical Conditions Associated with Hypergranulation:

Hypergranulation tissue can occur in association with various medical conditions, including:

Pressure Ulcers: Prolonged pressure on the skin, especially over bony prominences, can lead to the development of pressure ulcers, which may be complicated by hypergranulation tissue formation.

Surgical Wounds: Surgical incisions or wounds that fail to heal properly may develop hypergranulation tissue due to underlying factors such as infection or poor wound closure techniques.

Burn Injuries: Severe burn injuries can disrupt the skin's normal healing process, forming hypergranulation tissue as part of the body's response to tissue damage.

Traumatic Injuries: Trauma-related wounds, such as lacerations or abrasions, may develop hypergranulation tissue in response to tissue damage and inflammation.

Chronic Wounds: Wounds that fail to heal within the expected timeframe, such as venous ulcers or diabetic foot ulcers, are at increased risk of developing hypergranulation tissue due to underlying factors such as impaired circulation or compromised immune function.

How Does Hypergranulation Tissue Stall Healing

A. Mechanisms by Which Hypergranulation Tissue Impedes Wound Healing:

Hypergranulation tissue can impede the normal process of wound healing through various mechanisms, including:

Excessive Inflammation: Hypergranulation tissue is characterized by an exaggerated inflammatory response, leading to persistent inflammation within the wound bed. This chronic inflammation can disrupt the orderly progression of wound healing phases, including hemostasis, inflammation, proliferation, and remodeling.

Delayed Epithelialization: Hypergranulation tissue can delay epithelialization, the process by which new skin cells migrate and cover the wound surface. The excessive growth of granulation tissue can create a barrier that prevents the migration of epithelial cells, prolonging the wound-healing process.

Impaired Angiogenesis: Hypergranulation tissue can impair the formation of new blood vessels, a process known as angiogenesis, essential for delivering oxygen and nutrients to the wound bed. Without adequate blood supply, the wound may become hypoxic, compromising healing.

Increased Exudate Production: Hypergranulation tissue is often associated with increased exudate production, leading to excessive moisture within the wound environment. This excessive moisture can promote bacterial growth and create a favorable environment for infection, further delaying healing.

Wound Contraction Inhibition: Hypergranulation tissue can inhibit wound contraction, the process by which the wound edges pull together to reduce wound size. This inhibition of wound contraction can result in a larger wound area and prolong the healing process.

B. Impact on Wound Environment and Healing Progression:

Hypergranulation tissue can have a significant impact on the wound environment and the progression of healing, including:

Prolonged Healing Time: Wounds with hypergranulation tissue often experience lengthy healing times due to the impediment of the normal wound healing process. Hypergranulation tissue can delay wound closure and increase the risk of complications.

Increased Risk of Infection: Excessive moisture and chronic inflammation associated with hypergranulation tissue create an ideal bacterial growth and colonization environment. This increased risk of infection can further stall healing and lead to wound deterioration.

Compromised Wound Strength: Wounds with hypergranulation tissue may have compromised structural integrity due to abnormal tissue formation. This compromised wound strength can increase the risk of wound dehiscence or reopening and delay overall healing.

Chronic Wound Status: In some cases, wounds with hypergranulation tissue may become chronic, meaning they fail to progress through the normal stages of wound healing and remain open for an extended period. Chronic wounds are challenging to manage and may require specialized treatment approaches to promote healing.

Is Hypergranulation Serious?

A. Potential Complications Associated with Untreated Hypergranulation:

Untreated hypergranulation tissue can lead to several complications, including:

Delayed Wound Healing: Hypergranulation tissue can impede the natural healing process of wounds, leading to delayed wound closure and prolonged recovery times.

Increased Risk of Infection: Hypergranulation tissue creates a favorable environment for bacterial growth, increasing the risk of wound infection. Untreated infections can lead to systemic complications and further delay healing.

Chronic Wounds: If left untreated, hypergranulation tissue can contribute to developing chronic wounds, which are difficult to heal and may require specialized care.

Wound Dehiscence: In severe cases, hypergranulation tissue can compromise the structural integrity of the wound, leading to wound dehiscence or the separation of wound edges. This can result in open wounds prone to infection and delayed healing.

B. Risk Factors for Severe Hypergranulation Tissue:

Several factors may increase the risk of severe hypergranulation tissue, including:

Poor Wound Management: Inadequate wound care practices, such as improper dressing selection or poor wound hygiene, can contribute to the development of severe hypergranulation tissue.

Underlying Health Conditions: Certain medical conditions, such as diabetes, peripheral vascular disease, or immunodeficiency disorders, can impair the body's ability to heal wounds properly, increasing the risk of severe hypergranulation tissue.

Long-Term Wound Exposure: Wounds that remain open or untreated for an extended period are more likely to develop severe hypergranulation tissue. Prolonged exposure to moisture, friction, or trauma can exacerbate tissue overgrowth.

Inadequate Blood Supply: Poor blood circulation to the wound site can impair the delivery of oxygen and nutrients necessary for proper wound healing, leading to the development of severe hypergranulation tissue.

Wound Assessment

A. Importance of Thorough Wound Assessment:

Thorough wound assessment is essential for developing an effective treatment plan and monitoring the progress of wound healing. In the case of hypergranulation tissue, accurate assessment allows healthcare providers to identify the extent of tissue overgrowth and determine appropriate treatment strategies.

B. Key Parameters to Evaluate in Assessing Hypergranulation Tissue:

When assessing hypergranulation tissue, healthcare providers should consider the following key parameters:

Tissue Appearance: Hypergranulation tissue typically appears red, beefy, and excessively granulated tissue protruding above the wound surface. Visual inspection of the wound site can help differentiate hypergranulation tissue from other wound types.

Tissue Texture: Hypergranulation tissue may have a moist or friable texture and can bleed easily upon contact. Palpation of the wound area can provide valuable information about the texture and consistency of the tissue.

Wound Exudate: Excessive exudate production is common in wounds with hypergranulation tissue. Assessing the amount, color, and odor of wound exudate can help gauge the severity of tissue overgrowth and identify signs of infection.

Wound Size and Depth: Measuring the dimensions of the wound, including length, width, and depth, allows healthcare providers to track changes in wound size over time and assess the depth of tissue involvement.

C. Utilization of Wound Assessment Tools:

Various wound assessment tools and scales are available to standardize the evaluation of hypergranulation tissue and other wound characteristics. These tools may include:

Wound Measurement Tools: Rulers, calipers, or specialized wound measurement devices can facilitate accurate measurement of wound dimensions.

Wound Assessment Scales: Scales such as the Bates-Jensen Wound Assessment Tool or the Pressure Ulcer Scale for Healing can provide a structured framework for evaluating wound characteristics, including hypergranulation tissue.

Digital Imaging: Digital photography or wound imaging systems allow for wound appearance and progression documentation over time. High-resolution images can aid in treatment planning and communication among healthcare team members.

Thorough wound assessment, including visual inspection, palpation, and measurement, and appropriate assessment tools, enables healthcare providers to accurately diagnose hypergranulation tissue and tailor treatment interventions to individual patient needs.


A. Conservative Management Strategies:

Dressing Selection and Application: Choosing appropriate dressings is crucial in managing hypergranulation tissue. Non-adherent dressings such as silicone or hydrogel can help protect the wound bed while absorbing excess exudate. Additionally, barrier creams or films may be applied to prevent maceration of surrounding healthy tissue.

Moisture Management: Maintaining an optimal moisture balance in the wound environment is essential for controlling hypergranulation tissue. Moisture-retentive dressings promote autolytic debridement and facilitate wound healing. However, excessive moisture should be avoided to prevent further tissue overgrowth.

Compression Therapy: In cases where hypergranulation tissue is associated with venous insufficiency or edema, compression therapy may be beneficial. Compression bandages or stockings help improve venous return and reduce tissue edema, promoting wound healing.

B. Surgical Interventions:

Excision of Hypergranulation Tissue: Surgical excision of hypergranulation tissue may be necessary for cases resistant to conservative management. The excess tissue is carefully removed during the procedure to expose the underlying healthy wound bed. This allows for better visualization of the wound and promotes healing.

Electrocautery: Electrocautery involves using a high-frequency electrical current to cauterize and remove hypergranulation tissue. This technique helps control bleeding and sterilize the wound bed, facilitating healing.

Cryotherapy: Cryotherapy, or freezing therapy, utilizes extreme cold to destroy hypergranulation tissue. Liquid nitrogen or other cryogens are applied to the affected area, causing cell death and subsequent sloughing off excess tissue.

C. Novel Approaches and Emerging Treatments:

Topical Medications: Topical medications such as silver sulfadiazine or metronidazole gel may be applied to the wound bed to reduce inflammation and microbial colonization. Antimicrobial agents help prevent infection and promote granulation tissue formation.

Bioengineered Skin Substitutes: Bioengineered skin substitutes provide an alternative to traditional wound dressings by promoting tissue regeneration and wound closure. These products contain living cells or biological materials that facilitate wound healing and reduce the risk of hypergranulation tissue formation.

Laser Therapy: Laser therapy has shown promise in treating hypergranulation tissue. Low-level laser therapy (LLLT) helps reduce inflammation, improve blood circulation, and stimulate tissue repair processes. It can be used as an adjunctive therapy to enhance wound healing outcomes.

D. Patient Education and Follow-Up Care:

Patient education plays a crucial role in the successful management of hypergranulation tissue. Patients should be educated about proper wound care techniques, including dressing changes, moisture management, and signs of infection. Additionally, regular follow-up appointments with healthcare providers are essential to monitor wound progress, adjust treatment plans as needed, and address any concerns or complications.

By employing conservative management strategies, surgical interventions, novel approaches, and patient education, healthcare providers can effectively treat hypergranulation tissue and promote optimal patient wound healing outcomes.


Effectively managing hypergranulation tissue is paramount in facilitating optimal wound healing outcomes. Through conservative management strategies, surgical interventions, and emerging treatments, healthcare providers can address the underlying causes of hypergranulation tissue and promote wound closure. Patient education and diligent wound assessment are crucial in this process, ensuring that individuals receive appropriate care and follow-up. By employing these comprehensive approaches, healthcare providers can mitigate the complications associated with untreated hypergranulation tissue and support patients on their journey to healing and recovery.
