How To Spot Diabetic Foot Complications Early

Diabetic Foot Ulcer 101

Foot infections are among the most common health complications in people with diabetes. When a seemingly normal wound is left untreated, it can become severely infected.

We look at the reasons why diabetics should take special care of their feet.

Why diabetics are prone to foot conditions

Diabetics have abnormally high levels of glucose in their blood for long periods of time. This can lead to artery and nerve damage, which can compromise sensation in the feet.

When diabetics get a simple cut, scrape or foot ailment and they leave it untreated, it can lead to serious complications.

The two major conditions that can ultimately cause foot problems in diabetes are:

  • Neuropathy occurs because of nerve damage, causing diminished sensation in the feet. This can lead to injuries such as wounds or scrapes getting infected.
  • Peripheral vascular disease a condition that affects blood flow, making it more difficult for a cut or wound to heal.

Its not that these two conditions will cause ulcers as such, but they can result in extremely poor healing of any skin injuries. Often diabetics will have an injury, such as a blister or a cut, and because they have no feeling in that region, they do not realise that they have been hurt, and continue walking on an injured foot or leg, says podiatrist Chris Delpierre.

The risk of foot ulcers and amputation

This research also states that the risk of amputation is 15 to 46 times higher in diabetics than in people who do not have diabetes.

Tips To Prevent Ulcers

Thereâs a lot you can do to lower your chance of having ulcers in the first place:

Keep your blood sugar in check. Good blood sugar control is the single best way to prevent small cuts and sores from becoming ulcers. If you have trouble managing your blood sugar, tell your doctor. They can work with you to make changes to your medication and lifestyle that will keep your blood sugar from getting too high. Even if your blood sugar level is fairly steady, itâs still important to see your doctor regularly. Thatâs especially key if you have neuropathy, because you may not feel damage to your skin and tissue.

Check your skin every day, and pay special attention to your feet. Look for blisters, cuts, cracks, sores, redness, white spots or areas, thick , discoloration, or other changes. Donât rely on pain even feeling more warmth or cold than usual can be a sign that you have an open wound on your skin, and itâs possible that you may feel nothing at all.

Ulcers are most likely to form on the ball of your foot or the bottom of your big toe, so be sure to check your feet every night. If you notice a problem, or you arenât sure if somethingâs normal, call your doctor.

Donât smoke.Smoking damages your blood vessels, decreases blood flow, and slows healing. Those things raise your risk of ulcers and amputation.

Controlling Pressure In The Leg Veins

Controlling swelling is essential for patients with venous leg ulcers. Leg elevation, with the feet at or above the level of the heart, several times throughout the day and while sleeping, can help reduce swelling. Compression wraps or bandages are often applied to the legs. These can be changed as often as multiple times a day or as infrequently as once a week, depending on the amount of fluid draining from the ulcer. Once the leg ulcer is smaller or nearly healed, elastic compression stockings may be recommended. Compression stockings are sized to fit the legs and are typically put on in the morning and worn throughout the day. A venous pump may be prescribed for patients with severe swelling.

Tell Us About The Skin

Our research, for the first time, uncovered a skin-to-brain signaling pathway. It showed that the wound itself could cause subsequent central nervous system and behavioral changes.

We, and others, have observed behavioral and cognitive changes in our patients who have chronic wounds. It is unknown if the wound causes these changes, or they are just associated findings. The idea we proposed is that when a patient gets a wound that heals right away, there is not much sustained signaling of stress to the brain. But a chronic wound keeps activating the sensory receptors for painful stimuli , sending a more continuous skin-to-brain relay. This continuous flare generates brain signals of stress that are translated into behavioral changes.

We carried out research in mice and found that skin wounds result in a relay to the brain. This relay leads to the activation of stress markers, alteration of inflammatory mediators and changes in behavior and cognition. Mice with wounds showed more signs of despair and impaired memory than those with no wounds.

We often see similar behavior in patients with chronic wounds that need daily wound care. Some seem unable to attend to their wounds despite the serious risk of losing their foot to amputation. We also observe depression and cognitive disability reflected in the perception of inability to take care of their wounds. Some even seem to be disassociated from the reality of the serious nature of this problem.

When You Need More Treatment

If your wound doesnât heal in about a month or becomes an infection that spreads to the bone, you may need other treatments. These can include surgery and hyperbolic oxygen therapy, which involves breathing pure oxygen in a special room in order to help your body heal.

If your ulcer develops gangrene and your tissue dies, your doctor may have to amputate that area of your body.

What Type Of Treatment Is Given For Leg Ulcers

The type of treatment that you are given will depend upon the severity of the ulcer. If the ulcer hasnt completely formed and a sore hasnt broken out, you may only need to use compression stockings and keep the leg elevated. This will help reduce swelling and prevent the ulcer from forming.

If an open sore has developed on the lower leg, the treatment that is recommended will be more intense. Treatment for severe ulcers includes antibiotics to fight infections, surgery to clean the wound, and dressing to protect the wound. If it is determined the ulcer is caused by venous insufficiency, your doctor may recommend you seek treatment from a vein specialist to treat the problem.

Schedule an appointment at Vein911 to discuss treatment options for leg ulcers and vein insufficiency.

What Are My Treatment Options

What is a leg ulcer? Dr. Salti explains.

Treatment will depend on many factors, including the reason for the condition and your health status and history. Other factors your doctor will consider are:

  • Your specific symptoms.
  • How severe your condition is.
  • How well you can tolerate medications or procedures.

The most common treatment for venous insufficiency is prescription-wear compression stockings, she says. These special elastic stockings apply pressure at the ankle and lower leg. They help improve blood flow and can reduce leg swelling.

You also can improve blood flow by keeping your legs elevated whenever possible, which means keeping them uncrossed when you are seated and by exercising regularly.

If you need medication, the most commonly prescribed include:

  • Diuretics. These medications draw extra fluid from your body through your kidneys.
  • Anticoagulants. These medications thin the blood.
  • Pentoxifylline . This medication helps improve blood flow.

What To Look For

Han says patients should be aware of gradual changes in sensations in the foot, such as tingling, burning and the feeling of pins and needles. This is known as neuropathy, which is diagnosed by visiting a specialist. Neuropathy can eventually lead to a loss of sensation, which makes the person more likely to experience repetitive foot trauma. This trauma can lead to foot injuries and ulcers that may become infected. Diabetes patients with hammertoes and bunions need to pay particular attention to shoes, as improperly fitted shoes can lead to corns and calluses that can become infected wounds.

A specialist will also be able to identify gradual loss of blood circulation to the lower extremities. This is caused by vascular damage in the lower legs due to high circulating blood sugar, leading to a buildup of plaque in major lower leg arteries and reduced blood flow. It is therefore imperative that patients with diabetes maintain stable blood sugar levels to prevent this vascular damage, and to visit a podiatrist regularly.

In most cases, through vigilance and working with a podiatrist, diabetes patients can avoid these complications. Data has shown that keeping blood sugar at normal levels reduces the risk of diabetic complications, including foot complications, by 50%. His mission, Han says, is to teach people how to recognize any subtle signs to get timely intervention so that foot infection and wounds can be prevented. My motto is, Educate, dont amputate!

What Happens If Leg Ulcers Won’t Heal

What separates venous leg ulcers apart from other diseases is the heightened risk of infection you have through an open sore. âIf you have a wound that hasn’t healed in two to three weeks, see your doctor or nurse practitioner right away,â she says. âThey’ll evaluate you and get you a referral to a wound care center.â

Venous Ulcer Diagnosis And Treatment

The shocking images that reveal what diabetes can do to your feet in ...

Doctors at Vascular surgeons at UPMCs Heart and Vascular Institute use duplex ultrasound, a noninvasive test, to diagnose abnormal veins that cause venous ulcers. Part of the UPMC difference is that we actively look for the causes of the ulceration to treat venous pathology and keep the ulcer healed.

After an evaluation of your veins, we recommend a treatment plan based on your needs:

  • Compression of the leg is vital to healing venous wounds.
  • Compression stockings are most commonly used for this treatment.
  • The pressure from the compression dressing counteracts the pressure from the veins of the leg and allows skin to heal.
  • A moist gauze applied around the lower leg, from the base of the toes to just below the knee.
  • This gauze then hardens to form a snug boot on the leg.
  • The support from the boot helps improve blood flow in the veins and heal the ulcer.
  • Transparent dressings
  • A clear, plastic-like film applied over the wound.
  • A support stocking is worn over the dressing to help hold it in place and improve circulation in the extremity.
  • Hydrocolloid dressings
  • A dressing applied over the venous ulcer to promote healing.
  • It also helps to remove any nonliving tissue from the wound .
  • Investigational medicines applied to the wound in the hope of promoting the growth of new tissue.
  • Surgery or vein ablation
  • Sometimes minor surgery or vein ablation is used to remove any nonliving tissue that keeps a wound from healing properly.

    Diabetes: 12 Warning Signs That Appear On Your Skin

    Diabetes can affect many parts of your body, including your skin. When diabetes affects the skin, its often a sign that your blood sugar levels are too high. This could mean that:

    • You have undiagnosed diabetes, or pre-diabetes

    • Your treatment for diabetes needs to be adjusted

    If you notice any of the following warning signs on your skin, its time to talk with your doctor.

    How Does Diabetes Increase The Risk Of Leg Ulcers

    Neurotrophic ulcers, from nerve damage, affect diabetics who have high blood sugar levels.

    These ulcers form most often at pressure points on the bottom of the feet. The ulcer may be discolored, pink, red, brown, or black, and is an open wound. The surrounding skin is often discolored and calloused.

    Nerve damage to the legs or feet can cause symptoms such as a loss of feeling, changes to sweat glands, tingling, a burning or stinging feeling, and pain. These are predictive signs of a potential ulcer. Anyone with these symptoms should talk with a doctor and get checked.

    People with diabetes should check their legs and feet frequently. Make sure there are no calluses, scrapes, or cuts. Wear good, closed footwear, never walk barefoot, and keep your legs and feet clean.

    Treatment For Diabetic Ulcers

    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:

    • education on foot care and control of blood sugar levels
    • medications for blood sugar control
    • offloading pressure from the ulcer by using crutches, a wheelchair, or a non-removable cast to promote healing
    • medicines to help improve blood circulation
    • topical medications and dressings

    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.
