About one-third of people with diabetes develop a foot ulcer during their lifetime. Diabetic foot ulcers affect about People with diabetes often develop damage to their peripheral nerves neuropathy. Sensory neuropathy leads to decreased sensation of pain and pressure, which may cause people with diabetes not to feel a sharp object in their shoe that can puncture the skin and cause a foot ulcer.

Foot deformities and dry skin, which often occur with diabetic neuropathy, can lead to formation of a callus on the foot. Repetitive stress from walking or minor cuts and scrapes on the foot can cause a callus to develop into an ulcer. Individuals with diabetic foot ulcers and peripheral artery disease are at increased risk of developing infected ulcers and undergoing foot amputation.

Clinicians should examine the size and depth of a diabetic foot ulcer and look for signs of infection. Ultrasound imaging should be performed to evaluate blood flow in the legs. For some patients with a diabetic foot ulcer, laboratory testing for elevated blood inflammatory markers and imaging studies x-rays followed by magnetic resonance imaging [MRI] if needed are performed to determine if a bone in the foot has become infected.

Diabetic foot ulcers should be treated with wound care, surgical removal of any dead or infected tissue, and appropriate wound dressings.

Patients with infected diabetic foot ulcers need treatment with antibiotics. A knee-high cast or prefabricated boot can help healing by reducing pressure on the ulcer.

The risk of amputation is decreased when patients are cared for by a multidisciplinary care team, which typically includes a podiatrist, infectious disease specialist, vascular surgeon, and primary care clinician. Patients with a diabetic foot ulcer and peripheral artery disease may undergo leg bypass surgery to restore blood flow to the foot, which can decrease the risk of amputation.

Minimally invasive vascular surgical procedures endovascular therapy may also be used for patients with a diabetic foot ulcer and peripheral artery disease. Amputation of part or all of the foot may be required for patients with diabetic foot ulcers and infected bone.

People with a healed diabetic foot ulcer should be evaluated by a foot care professional every 1 to 3 months, receive instructions about how to properly monitor their feet, and be advised about footwear that fits well and reduces pressure on the feet.

A doctor will inspect the ulcer, noting its location, size, depth, and wound discharge. This will include looking for signs of infection, such as :.

The doctor will also try to identify the progression of ulceration and which factors may contribute to its development.

It classifies ulcers as follows:. After assessing the wound, they will also evaluate other functions, including :. When someone identifies an ulcer, they should seek medical care to prevent its progression.

The primary goal of treatment is to promote healing as soon as possible. Treatment will often depend on the grade of the ulcer. If an infection is present, a doctor will likely prescribe antibiotics.

They may require a tissue sample to identify the cause of the infection. The antibiotic type and dosage a doctor suggests will depend on the infection organism and the severity of the infection. In some cases, surgical options may be necessary to help encourage healing, relieve pressure on the area, and prevent further complications.

These options may include:. Some other strategies that may help to manage diabetic ulcers include:. The best treatment for diabetic ulcers is prevention. To help manage foot health, people should regularly check their feet and attend appointments with their podiatrist.

Depending on certain risk factors, a doctor may recommend regular foot examinations every 1—6 months. Tips to help prevent ulcers include:. If someone notices any trauma to their feet or other concerning areas, they should contact a doctor and receive prompt treatment.

Additionally, they should immediately seek medical attention if they see any signs of infection, including:. Diabetic ulcers are a common complication of diabetes. They refer to slow-healing wounds that often affect the feet. Without prompt treatment and management, they can result in severe complications.

Prolonged levels of high blood sugar can damage blood vessels and nerves. This can impact sensation and blood flow in the extremities, which affects wound healing and can lead to the development of ulcers.

Although they are a common complication, diabetic ulcers are highly preventable. Managing blood sugars, proper foot care, and certain lifestyle changes, such as quitting smoking if applicable, can all help reduce the likelihood of diabetic ulcers.

Your podiatric physician can test feet for neuropathy with a simple and painless tool called a monofilament. Once an ulcer is noticed, seek podiatric medical care immediately.

Foot ulcers in patients with diabetes should be treated for several reasons:. The primary goal in the treatment of foot ulcers is to obtain healing as soon as possible. The faster the healing of the wound, the less chance for an infection.

Not all ulcers are infected; however, if your podiatric physician diagnoses an infection, a treatment program of antibiotics, wound care, and possibly hospitalization will be necessary.

These devices will reduce the pressure and irritation to the ulcer area and help to speed the healing process. The science of wound care has advanced significantly over the past ten years.

We know that wounds and ulcers heal faster, with a lower risk of infection, if they are kept covered and moist. The use of full-strength betadine, peroxide, whirlpools and soaking are not recommended, as this could lead to further complications. Appropriate wound management includes the use of dressings and topically-applied medications.

These range from normal saline to advanced products, such as growth factors, ulcer dressings, and skin substitutes that have been shown to be highly effective in healing foot ulcers. For a wound to heal there must be adequate circulation to the ulcerated area.

Your podiatrist may order evaluation test such as noninvasive studies and or consult a vascular surgeon. Tightly controlling blood glucose is of the utmost importance during the treatment of a diabetic foot ulcer. Working closely with a medical doctor or endocrinologist to accomplish this will enhance healing and reduce the risk of complications.

A majority of noninfected foot ulcers are treated without surgery; however, when this fails, surgical management may be appropriate.

We've got more information on what to expect at the moment. In the meantime, follow your current routine including checking your feet daily , keep to a healthy diet and try to keep active.

If you spot something new you're concerned about, like a cut or blister on your foot , call your GP straight away and explain your situation. If you can't get through, call for advice. If you're already having treatment for a foot problem and you don't have coronavirus symptoms, then your appointments should still carry on.

If you're worried about going to your clinic or hospital at this time or want to check whether your appointment is still going ahead, contact your diabetes team or call the number on your appointment letter. Contact your GP or foot protection team immediately or go to your nearest out-of-hours healthcare service if your GP or foot protection team aren't available.

It's also really important to take the weight off your foot. If it's serious, it's likely you'll need a course of antibiotics and your feet will be covered with a dressing. A company limited by guarantee registered in England and Wales with no.
