How Diabetes Affects Your Body
Diabetes is a result of your bodys 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 bodys ability to heal wounds.
In people with diabetes, wounds tend to heal more slowly and progress more quickly, so its 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. About 15 percent of people who have diabetes develop foot ulceration.
For this reason, its crucial to 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 it along, and how to improve your bodys healing powers long term.
When you have diabetes, a number of factors can affect your bodys ability to heal wounds.
Research Design And Methods
The precise date of ulcer onset is often difficult to determine, especially for those ulcers that are long established or of which the patient was unaware. It was for this reason that a prospective decision had been taken to document ulcer onset simply by calendar month. For the purposes of calculating the ulcer duration at referral, the date of onset was taken as the 15th day of that month. For ulcers that started in the same month that they were first seen, the date of onset was taken as the 15th day of the month if they were seen after that date. For ulcers first seen in the first half of the month of onset, ulcer duration was arbitrarily taken as 7 days.
Usual clinical management for neuropathic ulcers relies on regular debridement to remove surrounding callus, combined with offloading. The principle of offloading was to adjust footwear to ensure that continued trauma to the ulcerated area was minimized, but the method adopted had to comply with that which was both safe and acceptable to each patient. The method of choice of offloading of neuropathic ulcers on the plantar surface of the foot was the use of irremovable padded fiberglass slippers and, less frequently, with below-the-knee irremovable casts. Patients who were judged unsafe in casts, or who refused to wear them, were managed with removable orthoses , with the aim of achieving the most effective offloading practicable.
Establishing Extent Of Infection
Early recognition of the area of involved tissue can facilitate appropriate management and prevent progression of the infection . The wound should be cleansed and debrided carefully to remove foreign bodies or necrotic material and should be probed with a sterile metal instrument to identify any sinus tracts, abscesses, or involvement of bones or joints.

Osteomyelitis is a common and serious complication of diabetic foot infection that poses a diagnostic challenge. A delay in diagnosis increases the risk of amputation.13 Risk factors associated with osteomyelitis are summarized in Table 1.3,1316 Visible bone and palpable bone by probing are suggestive of underlying osteomyelitis in patients with a diabetic foot infection.1314 Laboratory studies, such as white blood cell count and the erythrocyte sedimentation rate , have limited sensitivity for the diagnosis of osteomyelitis. Osteomyelitis is unlikely with normal ESR values however, an ESR of more than 70 mm per hour supports a clinical suspicion of osteomyelitis.13 Definitive diagnosis requires percutaneous or open bone biopsy. Bone biopsy is recommended if the diagnosis of osteomyelitis remains in doubt after imaging.3

Evidence Base For Wound Care Treatments
There is currently little evidence to justify the adoption of very many of the products and procedures currently promoted for use in clinical practice. Guidelines are required to encourage clinicians to adopt only those treatments that have been shown to be effective in robust studies and principally in RCTs. The design and conduct of such RCTs needs improved governance because many are of low standard and do not always provide the evidence that is claimed. There should be new guidance on the conduct of RCTs in this field, and it should embrace items such as those covered in the 21-item checklist of study quality reproduced as . Clinicians need to be able to assess the relative validity of published work, including its strengths and limitations in trial design, conduct, and reporting.

Ways Of Offloading To Prevent And Heal Foot Wounds
If using crutches or a wheelchair interferes too much with your everyday life, you may opt for a TCC or a removable cast walker.
A TCC evenly distributes weight across the entire sole of your foot so that a diabetic ulcer can heal without added weight strain.
A removable cast walker also helps redistribute weight and also allows you to easily dress and inspect your wound.
In addition to TCCs and removable cast walkers, there are special shoes and other types of footwear that help distribute your weight to prevent ulcers or help existing wounds heal.
If you have recurring foot ulcers or other diabetes-related foot problems, be sure to work with your physician to get the best foot care and protection available.

Pathogenesis Of The Diabetic Foot Ulcer
The diabetic foot ulcer is a complex multifactorial entity with a well-known etiologic pathway. The most common pathway is considered to be due to reduced peripheral sensation coupled with increased shear and/or compressive pressure . Brand discussed the concept of tenderizing the foot in which peripheral neuropathy leads to a loss of function of two types of mechanoreceptors in the skin, responsible for delivering nociceptive signals. High threshold mechano-receptors, carried via A-delta fibers, normally become sensitized to increased repetitive pressures on healthy tissues. This sensitization lowers the pain threshold in the patient with normal sensation, carried by polymodal nociceptors, leading to altered behaviors which reduce pain and subsequent damage. In the neuropathic patient this sensitization system is absent, allowing tissue damage to occur without any pain response with the subsequent diabetic foot ulcer.
Diabetic Wound Care: 6 Ways To Treat Diabetic Foot Ulcers
Neuropathic ulcers, often caused by diabetes, are slow to healeven more so as patients age, if they have longer-term diabetes, or if theyre smokers. Other factors that may stall healing include hypertension, hypercholesterolemia, and abnormal blood sugar levels, often associated with diabetes.
Diabetic ulcers typically occur below the ankle at any site of pressure, friction, shear, or trauma. The wound is likely to be round, with margins often characterized by a periwound callus. The presence of diabetes increases the risk for infection.
Treating neuropathic/diabetic ulcers can be challenging, so be sure to take the following steps to simplify the process and help improve outcomes:

Diagnosing A Diabetic Ulcer
An accurate diagnosis of a diabetic ulcer must be given by a medical health professional. Most doctors will first provide a physical examination of the patients foot. Should further tests be required, a doctor may recommend an X-ray or an MRI scan.
An X-ray can show any changes in foot alignment through a system of imaging. An X-ray image can show loss of bone mass and hormonal imbalances that can potentially relate to the diagnosis of diabetes.
MRI scans use three-dimensional images of the bodys soft tissue. If the extent of damage needs to be assessed, an MRI scan can use magnetic radio waves to reveal possible inflammation. This test can expose any significant infections in the foot.
One of the simplest tests a physician can use to diagnose an infectious diabetic ulcer is the blood test. This test is usually done by drawing blood at a doctors office so that the results can be sent to a lab for further information.
Proper Dressing Infection Control And Offloading
Its essential to use the proper types of wound dressing, infection control, and offloading to prevent your diabetic wound from regressing during or after treatment.
The best wound dressing maintains a healthy amount of moisture on the foot to create a favorable environment for the wound. It must be changed at least once or twice per day, depending on the stage and severity of the ulcer. Wound dressing helps control infection, as do antibiotics.
Offloading is also a very important but often overlooked component of diabetic foot ulcer treatment. When you offload, you remove pressure from your injured foot and give new, healthy cells the opportunity to thrive. Crushes, knee scooters, and wheelchairs all accomplish offloading.

Why Are Dfus So Hard To Heal
Poor circulation and high blood glucose levels are some of the leading reasons why wounds dont heal in diabetics. Elevated blood glucose can cause your blood vessels to narrow, and your platelets to grow larger, making it difficult for oxygen and nutrients to reach your wound site.
Another reason why wounds dont heal in diabetics is that high glucose levels inhibit your white blood cells, hindering your immune response. When you get a diabetic wound, its much more difficult for your body to heal and to fight off infection.
Once you notice you have an ulcer, its important to seek podiatric medical care for diabetes foot wound healing as soon as possible. If not managed properly, complications with infection can lead to osteomyelitis, amputation, and, in extreme cases, even death.
That being said, there are plenty of diabetic wound healing products and supplements you can use to properly manage your diabetes foot wound healing.
And of course, the best defense is to prevent your DFUs from happening in the first place!

Guidelines For Wound Bed Preparation In The Treatment Of Diabetic Ulcers
Preamble: Wound bed preparation is defined as the management of the wound to accelerate endogenous healing or facilitate the effectiveness of other therapeutic measures. The aim of wound bed preparation is to convert the molecular and cellular environment of a chronic wound to that of an acute healing wound.
Guideline #4.1: Examination of the patient as a whole is important to evaluate and correct causes of tissue damage. This includes factors such as: systemic diseases and medications, nutrition, and tissue perfusion and oxygenation.
Principle: A general medical history, including a medication record, will help in identifying and correcting systemic causes of impaired healing. The presence of a major illness or systemic disease and drug therapies such as immunosuppressive drugs and systemic steroids will interfere with wound healing by alterations in immune functioning, metabolism, inflammation, nutrition, and tissue perfusion. Autoimmune diseases such as rheumatoid arthritis, uncontrolled vasculitis, or pyoderma gangrenosum can all delay healing and may require systemic steroids or immunosuppressive agents before local wound healing can occur. Patients undergoing major surgery have a diminished wound-healing capacity as do chronic smokers. Smoking is associated with impaired wound healing and increased risk of infection.

Consensus Statement #: Vascular Management Infection Management And Prevention And Pressure Relief Are Essential To Dfu Healing
The acronym VIP is a useful tool to recall key concepts in the management of DFUs, and it is often cited in the wound care literature.13 Evidence suggests that if the clinician aggressively manages the VIPs, then the wound-healing trajectory will progress.1,2,5 In patients with diabetes, neuropathy is the primary risk factor for DFU. Without proper off-loading and pressure relief, successful healing outcomes will be unlikely.1,2 However, off-loading alone will fail to present optimal outcomes if vascular disease or infection is not appropriately managed.20

Vascular assessment requires a combination of physical examination and laboratory tests or screenings, which can include palpation of pulses, ankle or toe brachial index, skin perfusion pressure, and transcutaneous oximetry.1,9,11,13,23,26,29 However, the poor reliability of blood pressure indices in the diabetic population, such as the ankle brachial index , means that these indices should not be used as the only means of vascular assessment. Consultation with a vascular specialist is prudent for evaluation and appropriate intervention when vascular disease is suspected.1
