How does diabetes and obesity affect wound healing?
Obese people also have lower levels of the protein hormone adiponectin. In addition to impacting glucose regulation, adiponectin helps regulate wound healing through keratinocyte proliferation and migration, so decreased levels can impair perfusion and re-epithelialization of the wound.
How does obesity affect skin integrity?
The skin's ability to manage transepidermal water loss is altered in the obese population. With increased fat stores the transepidermal water loss is increased, resulting in dryness and delayed skin repair. Additionally, sebaceous channels are blocked, leading to an increase in oils and resulting in acne.
Which of the following explains why obesity is a risk factor for poor healing?
Decreased tissue perfusion and oxygenation. Blood supply to adipose tissue is usually compromised, which diminishes the oxygen and nutrients necessary to prevent breakdown and promote healing. Peripheral vascular diseases are often an important contributing factor due to low tissue oxygen levels.
How does obesity affect recovery from surgery?
Obese patients who undergo surgery are at greater risk for surgical site infection and slower healing because of reduced blood flow in fat tissue.
Why do overweight people get sores?
Retained moisture in body folds encourages the growth of bacteria and fungi, leading to skin rashes and potential breakdown and a variety of infections, such as intertrigo. Finally, the foot may develop corns and calluses due to the increased weight.
Why is obesity associated with increased risk of wound infection and dehiscence?
Poor perfusion and oxygenation of subcutaneous adipose tissue can predispose obese individuals to infection. Why? In a setting wherein there is insufficient oxygen, leukocytes are able to ingest bacteria but are unable to kill them, leading to infection which significantly impacts wound healing.
Is obesity a risk factor for wound infection?
Obesity is a risk factor for surgical site infection (SSI) after abdominal procedures; however, data characterizing the risk of SSI in obese patients during abdominal procedures are lacking. We hypothesized that obesity is an independent risk factor for SSI across wound classes.
How does obesity increase risk of infection?
Obesity is associated with an altered immune response [4] and chronic inflammation [5], which can lead to an increased risk of infection. Excessive weight also stresses the respiratory system, increases soft tissue burden, and impairs skin and urinary tract hygiene [6, 7].
How does obesity cause pressure ulcers?
Immobility is a risk factor for pressure ulcers in hospitalized patients. Obesity contributes to immobility in the ICU and subsequent pressure on skin surfaces. Helping obese patients change their position in bed to relieve sites of increased skin pressure is a challenge for caregivers.
Why do obese people need to lose weight before surgery?
But if you are obese and facing surgery, losing weight before your procedure can be even more important. Losing weight lowers your risk for serious surgery-related complications such as infection, blood clots, and heart attack.
Does fat make surgery harder?
The more fat you have, the more difficult the operation is for the surgeon. Excessive fatty tissue impairs access to the surgical site. It can also make the surgery itself — the cutting of tissue — more complex.
Why does your BMI matter for surgery?
Improved Recovery Often, people who are determined to be obese due to a high BMI have a weakened immune system and chronic inflammation. This can slow down your recovery rate, increase pain and inflammation after surgery, and increase the risk of infection or complications after your procedure.
Does obesity cause skin discoloration?
A body that carries too much weight can lead to insulin resistance. When this happens, darkened, velvety patches called acanthosis nigricans can form, especially in areas where skin folds and overlaps like the knees, elbows, groin, armpits, and neck. Patches may appear grey, brown, or black.
Does obesity cause red skin?
Conclusions. Characteristics of obesity-associated skin were (A) reduction of the barrier and moisturizing function accompanied by intercellular lipid imbalance, (B) increased redness accompanied by hemodynamic changes, and (C) surface roughness.
Does obesity cause acne?
Acne is clearly exacerbated by obesity-associated disorders. In obese individuals androgens (male hormones), insulin, growth hormone, and insulin like growth factors are raised. These are all known risk factors for acne.
Does obesity cause eczema?
We found evidence of a small overall association between atopic eczema and being overweight or obese. However, there was no association with obesity among those with the most severe eczema.
What are the challenges of being obese?
Obese (bariatric) patients also face numerous challenges in maintaining their skin integrity. Common dermatological conditions include acanthosis nigricans, skin tags, hyperandrogenism , striae distensae , plantar hyperkeratosis, and candidal intertrigo. These health complications and skin integrity challenges also place the bariatric patient at increased risk for surgical complications and delayed wound healing. The risk factors and potential complications increase with the severity of obesity.
What is obesity?
Obesity is defined as a body mass index of greater than 30 kg/m2 and morbid obesity as a BMI of greater than 40 kg/m2. Common health complications related to obesity include type 2 diabetes, hypertension, coronary artery disease, osteoarthritis of weight-bearing joints, respiratory problems, gastroesophageal disease, depression, infertility, and urinary stress incontinence.
How can clinicians help and care for bariatric patients?
With these challenges to skin integrity in mind, it is necessary to plan for the provision of safe and effective assessment and care for the bariatric patient. Obese individuals should receive dignity and respect during care with the same access to technical excellence, accessibility, and acceptability as others. Keen attention to nutritional needs, skin/wound assessment, cleanliness, skin fold assessment/management, perigenital care, odor management, perioperative management, and effective pressure redistribution is an integral component of skin and wound care for the bariatric individual.
What causes low oxygen levels in the adipose tissue?
Blood supply to adipose tissue is usually compromised, which diminishes the oxygen and nutrients necessary to prevent breakdown and promote healing. Peripheral vascular diseases are often an important contributing factor due to low tissue oxygen levels. Oxygenation of the bariatric patient is also impacted by a decreased lung volume, exertional dyspnea, obstructive sleep apnea, and obesity hypoventilation syndrome.
What is skin integrity?
Skin integrity is impacted by adequate nutrition, and complications in the bariatric patient are often exacerbated by nutritional deficits in protein, vitamin, or mineral stores. Proper equipment and resources for care delivery. Standard care equipment, such as beds, side chairs, toilets, and lifting aids, are just a few items typically rated ...
What is the role of adiponectin in wound healing?
Adiponectin aids in stimulating angiogenesis (new blood vessel formation) as well as promoting the proliferation and migration of keratinocytes to close wounds. 5.
Why does the circulatory system become stressed?
Several things occur as we gain weight. First, the demands on the circulatory system are stressed due to the increased amount of adipose (fat) tissue. The vascular system becomes overwhelmed and can’t supply the required oxygen and nutrients, resulting in chronic inflammation. 4 Decreased tissue oxygenation also negatively affects the ability of fibroblasts to produce collagen, a vital component for healing and wound tensile strength. 5
Do you need protein for wound healing?
It is well known that an adequate supply of vitamins, minerals and protein are necessary for wound healing. 2 A proper assessment of the obese individual’s dietary requirements may reveal the need for protein supplements.
What are the causes of wounds?
Wound Factors: Obesity and Malnutrition. Malnutrition is a common occurrence in both obese individuals and frail, underweight adults. It is defined as any nutritional imbalance that is an over and under consumption of calories and nutrients. Overweight or obese individuals who experience a traumatic event or severe acute illness benefit ...
Can you eat meat if you are obese?
Recommending the obese individual who has wounds embark on a restricted very low calorie diet is not appropriate until the skin is healed. Rather, the focus should be on incorporating lean meats, poultry, fish, eggs, low fat cheese and dairy products, beans, legumes, fresh fruits, and vegetables either cooked without added fat or raw. If the diet is lacking in the adequate vitamins and minerals, then it is appropriate to suggest a multivitamin with minerals. Remember that being overweight does not equate with being well nourished.
What are the factors that affect wound healing?
The factors discussed include oxygenation, infection, age and sex hormones, stress, diabetes, obesity, medications, alcoholism, smoking, and nutrition. A better understanding of the influence of these factors on repair may lead to therapeutics that improve wound healing and resolve impaired wounds.
Why is oxygen important for wound healing?
Oxygen is important for cell metabolism, especially energy production by means of ATP, and is critical for nearly all wound-healing processes. It prevents wounds from infection, induces angiogenesis, increases keratinocyte differentiation, migration, and re-epithelialization, enhances fibroblast proliferation and collagen synthesis, and promotes wound contraction (Bishop, 2008; Rodriguez et al., 2008). In addition, the level of superoxide production (a key factor for oxidative killing pathogens) by polymorphonuclear leukocytes is critically dependent on oxygen levels.
How do macrophages help heal wounds?
In the early wound, macrophages release cytokines that promote the inflammatory response by recruiting and activating additional leukocytes. Macrophages are also responsible for inducing and clearing apoptotic cells (including neutrophils), thus paving the way for the resolution of inflammation. As macrophages clear these apoptotic cells, they undergo a phenotypic transition to a reparative state that stimulates keratinocytes, fibroblasts, and angiogenesis to promote tissue regeneration (Meszaros et al., 2000; Mosser and Edwards, 2008). In this way, macrophages promote the transition to the proliferative phase of healing.
What are the roles of T lymphocytes in wound healing?
T-lymphocytes migrate into wounds following the inflammatory cells and macrophages, and peak during the late-proliferative/early-remodeling phase. The role of T-lymphocytes is not completely understood and is a current area of intensive investigation. Several studies suggest that delayed T-cell infiltration along with decreased T-cell concentration in the wound site is associated with impaired wound healing, while others have reported that CD 4+ cells (T-helper cells) have a positive role in wound healing and CD8+ cells (T-suppressor-cytotoxic cells) play an inhibitory role in wound healing (Swift et al., 2001; Park and Barbul, 2004). Interestingly, recent studies in mice deficient in both T- and B-cells have shown that scar formation is diminished in the absence of lymphocytes (Gawronska-Kozak et al., 2006). In addition, skin gamma-delta T-cells regulate many aspects of wound healing, including maintaining tissue integrity, defending against pathogens, and regulating inflammation. These cells are also called dendritic epidermal T-cells (DETC), due to their unique dendritic morphology. DETC are activated by stressed, damaged, or transformed keratinocytes and produce fibroblast growth factor 7 (FGF-7), keratinocyte growth factors, and insulin-like growth factor-1, to support keratinocyte proliferation and cell survival. DETC also generate chemokines and cytokines that contribute to the initiation and regulation of the inflammatory response during wound healing. While cross-talk between skin gamma-delta T-cells and keratinocytes contributes to the maintenance of normal skin and wound healing, mice lacking or defective in skin gamma-delta T-cells show a delay in wound closure and a decrease in the proliferation of keratinocytes at the wound site (Jameson and Havran, 2007; Mills et al., 2008).
What is ECM in wounds?
ECM, extracellular matrix. Wounds that exhibit impaired healing, including delayed acute wounds and chronic wounds, generally have failed to progress through the normal stages of healing. Such wounds frequently enter a state of pathologic inflammation due to a postponed, incomplete, or uncoordinated healing process.
Why do ulcers not heal?
Many chronic ulcers probably do not heal because of the presence of biofilms containing P. aeruginosa, thus shielding the bacteria from the phagocytic activity of invading polymorphonuclear neutrophils (PMNs). This mechanism may explain the failure of antibiotics as a remedy for chronic wounds (Bjarnsholt et al., 2008).
How do GCs affect immune cells?
Furthermore, GCs influence immune cells by suppressing differentiation and proliferation, regulating gene transcription, and reducing expression of cell adhesion molecules that are involved in immune cell trafficking (Sternberg, 2006).
How does obesity affect ulcers?
Pressure ulcers are more likely to develop in obese patients through pressure-related ischemia and hypovascularity, as well as decreased mobility. Contact between the skin and various hospital surfaces (e.g., stretchers, operating room tables) may result in friction, leading to ulceration and wound formation. Systemic effects of obesity, such as hypertension, hyperglycemia, and upregulation of the stress hormones in response to the physiologic burden of surgery and acute illness, all work to impair further wound healing. Additional factors involved in this complex process include blunting of the immune and inflammatory responses. Interestingly, these ill-effects of obesity are largely reversible through weight loss [24].
What is the history of wound care?
In a way, history of wound care is the history of humankind. Well before any written historical record, chronic wounds of all shapes and sizes have plagued patients and created a significant burden on their caretakers. It has long been noticed that some patient factors are more likely to be associated with better wound healing [1][2][3]. Likewise, certain wound types have been noted to be associated with a better prognosis than others. Until recently, there has been little scientific evidence regarding the risk factors and characteristics, both positive and negative, responsible for wound healing behaviors [4][5]. This article will review factors that lead to poor wound healing and the latest advances in their care.
How does negative pressure wound therapy work?
NPWT involves the application of subatmospheric pressure on wound via a sponge-based system with an airtight seal directly over the wound, connected under sealed conditions to a suction device. Benefits of NPWT are realized via several different mechanisms. First, the subatmospheric pressure applied to the wound helps to remove wound exudate and other materials that are known to impair the WHP. Secondly, the presence of subatmospheric pressure promotes angiogenesis and tissue perfusion by increasing cellular proliferation and migration into the wound. The suction also assists in bringing wound edges together. When combined, all of the above elements and mechanisms work synergistically to help speed up wound healing. NPWT devices can be used on a wide variety of wounds, such as pressure ulcers, large abdominal wounds, traumatic wounds, as well as complex, difficult-to-cover tissue defects following debridement operations (e.g., in the setting of necrotizing soft tissue infections) [27][28][29][30][31][30][27]. Of note, NPWT is contraindicated in certain situations, such as wound surfaces involving malignancy, untreated osteomyelitis, non-enteric and unexplored fistulae, and necrotic tissue with eschar (e.g., non-debrided wounds) [27][32][33][31][27].
What is WHP in wound healing?
The WHP is very complex and involves high levels of coordination between multiple tissues and cell types [6]. Consequently, impairment in the process can occur at any step along the sequence that leads to process completion. Many known factors can affect or modulate wound healing [7]. In the subsequent sections, we will discuss major modulators (both positive and negative) of the WHP, including a summary of some of the methods and techniques devised to promote wound healing [9].
How does stress affect the body?
Stress has been demonstrated to be a major contributor to a broad range of health conditions and illnesses, including cardiovascular disease, cancer, and obesity. Stress states lead to upregulation of stress hormones via the hypothalamic-pituitary axis and the release of adrenocortical hormones. Resultant changes include elevated levels of cortisol, glucocorticoids, and catecholamines. Cortisol works to blunt the immune response by blocking the production of important cytokines such as IL-1beta, IL-6, and TNF-alpha. The impairment of immune response ultimately leads to deficient wound healing [25][26].
Does diabetes affect wound healing?
There is no doubt that diabetes plays a detrimental role in wound healing. It does so by affecting the WHP at multiple steps. Wound hypoxia, through a combination of impaired angiogenesis, inadequate tissue perfusion, and pressure-related ischemia, is a major driver of chronic diabetic wounds [10]. Ischemia can lead to prolonged inflammation, which increases the levels of oxygen radicals, leading to further tissue injury. Elevated levels of matrix metalloproteases in chronic diabetic wounds, sometimes up to 50-100 times higher than acute wounds, cause tissue destruction and prevent normal repair processes from taking place [10]. Furthermore, diabetes is associated with impaired immunity, with critical defects occurring at multiple points within the immune system cascade of the WHP. For example, neutrophils show impaired chemotaxis and phagocytosis. As a result, diabetic wounds are prone to chronic infection due to inadequate bacterial clearance [10]. To further complicate matters, these wounds have defects in angiogenesis and neovascularization. Normally, wound hypoxia stimulates mobilization of endothelial progenitor cells via vascular endothelial growth factor (VEGF)[8]. In diabetic wounds, there are aberrant levels of VEGF and other angiogenic factors such as angiopoietin-1 and angiopoietin-2 that lead to dysangiogenesis [11]. Diabetic neuropathy may also play a role in poor wound healing. Lower levels of neuropeptides, as well as reduced leukocyte infiltration as a result of sensory denervation, have been shown to impair wound healing [10]. When combined, all these diverse factors play a role in the formation and propagation of chronic, debilitating wounds in patients with diabetes.
Is obesity a factor in wound healing?
Obesity is a significant factor in surgical wound healing . Abdominal obesity is correlated with oxidative stress, a phenomenon associated with deficiency of adiponectin (e.g., adipose-derived cytokine with antioxidant and anti-inflammatory properties). Adiponectin-deficient state leads to impaired perfusion and reepithelialization of the wound. Moreover, hypovolemia combined with relative hypoperfusion and reduction in oxygen delivery lead to further tissue injury. Consequently, wound complications, including surgical site infections and fat necrosis are more prevalent in obese patients. Various combinations of the same factors may be associated with impaired secondary healing following primary wound-related morbidity [23].
