The Role Of Glucose In Wound Healing
Maintaining a healthy blood sugar level is important to the wound healing process. People who have been diagnosed with diabetes are well aware that their bodies may not recover from wounds as efficiently as those without the metabolic condition. For that reason, clinicians heavily stress the importance of diabetic wound care. Maintaining healthy blood sugar levels, staying aware of the condition of the feet and properly caring for lesions and abrasions on the feet are all essential to avoiding infections that could lead to gangrene and, in severe cases, amputation. While many know that blood sugar plays a big role in wound recovery, the precise reason why may still remain a mystery. Learn more about how glucose affects the body and, when too high, can inhibit the healing process. How does blood glucose affect healing? When a person has high glucose levels, they may experience difficulty healing from wounds. That’s because an increased amount of sugar in the blood causes the cell walls to become stiff and rigid, impairing the flow of blood throughout the small vessels located at the surface of the wound. This, in effect, impedes the flow and permeability of red blood cells, which are required for the development of dermal tissue, according to a study conducted at the University of British Columbia. Another way that high glucose levels affect the wound healing process is by impairing the hemoglobin release of oxygen. By doing so, it effectively starves the affected area of oxygen and nutrients that promote healing. The importance of balancing blood sugar Diabetes patients may understand how unbalanced blood sugar can affect the body’s ability to recover from a wound. However, many do not comprehend the severity of the situation. As the journal Ostomy Wound Management Continue reading >>
Mechanism Identified Behind Impaired Wound Healing In Diabetics
A molecule has been identified by researchers at the University of Pennsylvania School of Dental Medicine that may explain why wound healing is impaired in people with diabetes. The scientists behind the discovery believe the molecule may also offer a new target for therapies that could improve healing. About 15% of diabetics will have a non-healing wound at some point in their lifetime, and in some cases, these non-healing open ulcers can be so severe that they lead to amputations. In 2013, a study found - contrary to previous research - that the Foxo1 molecule promotes healing by both protecting cells against oxidative stress and inducing a molecule called TGF-β1 that is critical for wound healing. The Penn team wanted to investigate whether these mechanisms are also implicated in the reduced capacity for wound healing among people with diabetes. To do this, the researchers first created small wounds on the tongues of mice with diabetes and a control group of non-diabetic mice. The wounds of the diabetic mice - as might be expected - healed more slowly than the control mice. The team then repeated this experiment in mice bred to lack Foxo1 in a type of cell called keratinocytes, which "fill in" the holes left by injuries. The researchers were surprised to find that the absence of the Foxo1 protein and FOXO1 gene in the keratinocytes appeared to cause the diabetic mice to heal more quickly. Next, the team experimented with cells in culture. The researchers found that cells grown in a "high-sugar media" were less able to move and proliferate, compared with cells grown in standard solution. The same slowed proliferation of cells was observed by the researchers in diabetic mice; because the cells were slow to proliferate, they closed the wound over the keratinocyte filli Continue reading >>

How Does Diabetes Affect The Human Body?
I am not an expert, Just a Learner. Knowing how diabetes affects your body can help you look after your body and prevent diabetic complications from developing. Many of the effects of diabetes stem from the same guilty parties; namely high blood pressure, high cholesterol levels and a lack of blood glucose control. Signs of diabetes When undiagnosed or uncontrolled, the effects of diabetes on the body can be noticed by the classic symptoms of diabetes, namely: Long term effects of diabetes on the body In addition to the symptoms, diabetes can cause long term damage to our body. The long term damage is commonly referred to as diabetic complications. Diabetes affects our blood vessels and nerves and therefore can affect any part of the body. However, certain parts of our body are affected more than other parts. Diabetic complications will usually take a number of years of poorly controlled diabetes to develop. Complications are not a certainty and can be kept at bay and prevented by maintaining a strong level of control on your diabetes, your blood pressure and cholesterol. These can all be helped by keeping to a healthy diet, avoiding cigarettes and alcohol, and incorporating regular activity into your daily regime in order to keep blood sugar levels within recommendedblood glucose level guidelines. The effect of diabetes on the heart Diabetes contributes to high blood pressure and is linked with high cholesterol which significantly increases the risk of heart attacks and cardiovascular disease. Diabetes and strokes Similar to how diabetes affects the heart, high blood pressure and cholesterol raises the risk of strokes. How diabetes affects the eyes As with all complications, this condition is brought on by a number of years of poorly controlled or uncontrolled diabetes Continue reading >>
How Diabetes Affects Wound Healing
Diabetes is characterized by the body’s inability to produce insulin and/or use it properly due to high blood glucose levels. The American Diabetes Association estimates that approximately 25 million people in the United States alone have diabetes, about 7 million of whom are undiagnosed. One of the most common complications of diabetes is chronic wounds that primarily affect the feet. Diabetes inhibits the body’s natural wound-healing capabilities, which means chronic wounds can quickly become severe and develop infections if left untreated. Diabetes affects wound healing in a variety of ways, including: Reduced circulation – High blood glucose levels can cause the blood vessels to constrict, which reduces blood flow to the extremities. Circulation is an essential part of the body’s natural wound-healing process, as the blood delivers oxygen to the wound and helps to fight infection. Neuropathy – Loss of circulation can cause nerve damage in the feet, which limits sensation. Someone with diabetic neuropathy may not realize they have developed wounds on their feet, or may be more prone to foot injuries. Immune system deficiency – High glucose levels can affect the body’s immune system, which can increase the risk of wound infection in the feet and inhibit the body’s natural healing process.

What’s The Connection Between Diabetes And Wound Healing?
Diabetes is a result of your body’s inability to produce or use insulin. Insulin is a hormone that allows your body to turn glucose, or sugar, into energy. If your body has difficulty metabolizing glucose, it can lead to high blood sugar levels. This can affect your body’s ability to heal wounds. In people with diabetes, wounds tend to heal more slowly and progress more quickly, so it’s important to know what to look out for. Although cuts, grazes, scratches, and blisters can occur anywhere on the body, the feet are one of the most common places of injury. A small wound on the foot can quickly develop into a foot ulcer. Foot ulcers can become serious if left untreated. Between 14 and 24 percent of people who have diabetes and develop an ulcer will end up having a lower limb amputation. For this reason, it’s crucial that you do regular self-checks and closely monitor any wounds closely. Catching wounds early is the only way to reduce your risk of complications. Keep reading to learn more about the healing process, ways to speed the healing process along, and how to improve your body’s healing powers long-term. When you have diabetes, a number of factors can affect your body’s ability to heal wounds. High blood sugar levels Your blood sugar level is the main factor in how quickly your wound will heal. When your blood sugar level is higher than normal, it: prevents nutrients and oxygen from energizing cells prevents your immune system from functioning efficiently increases inflammation in the body’s cells These effects slow down wound healing. Neuropathy Peripheral neuropathy can also result from having blood sugar levels that are consistently higher than normal. Over time, damage occurs to the nerves and vessels. This can cause the affected areas to lose sen Continue reading >>
How Diabetes Affects Wound Healing
Diabetes is a condition in which the body does not effectively use sugar. It is estimated that there are nearly 18 million Americans with diabetes, and approximately 15 percent of diabetics will develop a foot ulcer at some point. Foot ulcers are the most common wounds for this patient population. Wound healing can be slowed when the patient is diabetic. An important point to remember about a diabetic patient wound is that it heals slowly and can worsen rapidly, so requires close monitoring. There are several factors that influence wound healing in a diabetic patient, and may include: Blood Glucose Levels It all starts here. An elevated blood sugar level stiffens the arteries and causes narrowing of the blood vessels. The effects of this are far-reaching and include the origin of wounds as well as risk factors to proper wound healing. Poor Circulation Narrowed blood vessels lead to decreased blood flow and oxygen to a wound. An elevated blood sugar level decreases the function of red blood cells that carry nutrients to the tissue. This lowers the efficiency of the white blood cells that fight infection. Without sufficient nutrients and oxygen, a wound heals slowly. Diabetic Neuropathy When blood glucose levels are uncontrolled, nerves in the body are affected and patients can develop a loss of sensation. This is called diabetic neuropathy. When there is a loss of sensation, patients cannot feel a developing blister, infection or surgical wound problem. Because a diabetic patient may not be able to feel a change in the status of a wound or the actual wound, the severity can progress and there may be complications with healing. Immune System Deficiency Diabetes lowers the efficiency of the immune system, the body's defense system against infection. A high glucose level ca Continue reading >>
Connexins In Wound Healing; Perspectives In Diabetic Patients
Skin lesions are common events and we have evolved to rapidly heal them in order to maintain homeostasis and prevent infection and sepsis. Most acute wounds heal without issue, but as we get older our bodies become compromised by poor blood circulation and conditions such as diabetes, leading to slower healing. This can result in stalled or hard-to-heal chronic wounds. Currently about 2% of the Western population develop a chronic wound and this figure will rise as the population ages and diabetes becomes more prevalent . Patient morbidity and quality of life are profoundly altered by chronic wounds . Unfortunately a significant proportion of these chronic wounds fail to respond to conventional treatment and can result in amputation of the lower limb. Life quality and expectancy following amputation is severely reduced. These hard to heal wounds also represent a growing economic burden on Western society with published estimates of costs to healthcare services in the region of $25B annually . There exists a growing need for specific and effective therapeutic agents to improve healing in these wounds. In recent years the gap junction protein Cx43 has been shown to play a pivotal role early on in the acute wound healing process at a number of different levels [4–7]. Conversely, abnormal expression of Cx43 in wound edge keratinocytes was shown to underlie the poor rate of healing in diabetic rats, and targeting its expression with an antisense gel restored normal healing rates . The presence of Cx43 in the wound edge keratinocytes of human chronic wounds has also been reported . Abnormal Cx43 biology may underlie the poor healing of human chronic wounds and be amenable therapeutic intervention . This article is part of a Special Issue entitled: The Comm Continue reading >>

Diabetes Medications: Impact On Inflammation And Wound Healing
Abstract Chronic wounds are a common complication in patients with diabetes that often lead to amputation. These non-healing wounds are described as being stuck in a persistent inflammatory state characterized by accumulation of pro-inflammatory macrophages, cytokines and proteases. Some medications approved for management of type 2 diabetes have demonstrated anti-inflammatory properties independent of their marketed insulinotropic effects and thus have underappreciated potential to promote wound healing. In this review, the potential for insulin, metformin, specific sulfonylureas, thiazolidinediones, and dipeptidyl peptidase-4 inhibitors to promote healing is evaluated by reviewing human and animal studies on inflammation and wound healing. The available evidence indicates that diabetic medications have potential to prevent wounds from becoming arrested in the inflammatory stage of healing and to promote wound healing by downregulating pro-inflammatory cytokines, upregulating growth factors, lowering matrix metalloproteinases, stimulating angiogenesis, and increasing epithelization. However, no clinical recommendations currently exist on the potential for specific diabetic medications to impact healing of chronic wounds. Thus, we encourage further research that may guide physicians on providing personalized diabetes treatments that achieve glycemic goals while promoting healing in patients with chronic wounds.

Slow Healing Of Cuts And Wounds
Tweet Wounds or sores that take more than a few weeks to heal might be infected and require medical treatment, and often indicate an underlying disease such as diabetes. When you cut or burn yourself, your body begins a three-stage process to repair the damaged skin. First, an immune response causes the wound to become inflamed to prevent infections. Second, new cells (a scab) form over the wound, and finally scar tissue forms to heal the wound. Some wounds heal easily while others can take longer, particularly if they are severe or the individual has a poor state of health. Causes of slow wound healing There are a number of things that can delay or complicate the healing of wounds, including: Diabetes and slow healing wounds High levels of blood glucose caused by diabetes can, over time, affect the nerves (neuropathy) and lead to poor blood circulation, making it hard for blood - needed for skin repair - to reach areas of the body affected by sores or wounds. This can cause them to remain open and unhealed for months, increasing the risk of: Fungal infections Bacterial infections Gangrene Keeping blood glucose levels under good control can help to reduce the risk of slow healing wounds now and further in the future. Slow healing wounds can be a symptom of undiagnosed diabetes, particularly if other symptoms are also present. Slow healing of wounds, including cuts, grazes and blisters, can be particularly problematic if they affect the feet of someone with diabetes and if not treated properly, can raise the risk of amputation. It is important therefore that people with diabetes check their feet daily and report any signs of damage to their health team. When to see your doctor If you do not have diabetes and a cut or burn is taking a long time to heal or showing signs of Continue reading >>

Micronutrients And Natural Compounds Status And Their Effects On Wound Healing In The Diabetic Foot Ulcer
The diabetic foot ulcer (DFU) is an invariably common complication of diabetes mellitus, it is also a significant cause of amputation as well as extended hospitalization. As most patients with DFU suffer from malnutrition, which has been related to improper metabolic micronutrients status, alterations can affect impaired wound healing process. Micronutrients and herbal remedies applications present a wide range of health advantages to patients with DFU. The purpose of this review is to provide current evidence on the potential effect of dietary supplementations such as vitamins A, C, D, E, magnesium, zinc, copper, iron, boron, and such naturally occurring compounds as Aloe vera, Naringin, and Radix Astragali (RA) and Radix Rehmanniae (RR) in the administration of lower extremity wounds, especially in DFU, and to present some insights for applications in the treatment of DFU patients in the future. 1.
