Comprehensive diagnosis and treatment of diabetic foot disease—from prevention and high-risk foot care to ulcers, infection, Charcot foot, osteomyelitis, and limb-preserving surgery.
At Seattle Foot and Ankle Center, Dr. Hoy specializes in comprehensive diabetic foot care, including diabetic ulcers, diabetic foot infections, Charcot foot, peripheral neuropathy, advanced wound care, and limb preservation.
Many diabetic foot wounds are not simply skin problems. They are often the result of pressure imbalance, deformity, neuropathy, infection, or circulation problems. Effective treatment requires identifying and addressing the underlying cause—not simply managing the wound surface.
Dr. Hoy’s limb preservation background includes hospital-based diabetic wound and infection management in San Antonio during the formative years of modern diabetic limb preservation, where podiatric medicine worked directly alongside vascular surgery and infectious disease as part of comprehensive hospital care.
With years of experience in areas like South Texas and at the Veteran’s Affairs Hospital—where diabetes prevalence is high—Dr. Hoy is passionate about diabetic limb preservation, amputation prevention, and preserving mobility in high-risk diabetic patients. He has extensive experience treating diabetic wounds and managing complex limb preservation cases in high-risk populations.
If you live in the Seattle area and have diabetes, regular podiatric care is critical to maintaining foot health and avoiding severe complications such as infections or amputations.

Foot and Ankle Problems Deserve Specialist Evaluation Early
Diabetic foot wounds require prompt medical attention because even small ulcers can progress rapidly if underlying pressure, infection, circulation problems, or bone involvement are not recognized. Wound care centers provide important expertise in wound healing, dressings, and advanced therapies, but successful treatment often depends on identifying why the wound developed in the first place.
A diabetic foot problem may involve neuropathy, abnormal pressure, deformity, infection, bone involvement, circulation problems, or several of these at once. The first step is therefore a comprehensive foot and ankle evaluation—not simply treatment of the wound surface.
Dr. Hoy evaluates the underlying foot problem, provides treatment within the practice when appropriate, and coordinates vascular, infectious disease, wound care, endocrinology, hospital, or other specialty care when needed.
- Foot pain not improving?
- Foot fracture or stress fracture? Early diagnosis matters.
- Diabetic foot wounds or skin changes? Early treatment can prevent complications.
- Persistent ankle pain after a sprain?
When the problem persists despite initial treatment, the diagnosis and contributing factors may need to be reassessed.

Why Diabetic Foot Care Matters
Diabetes affects millions of Americans each year and can severely impact the feet. High blood sugar levels can lead to peripheral neuropathy, poor circulation (peripheral arterial disease), diabetic ulcers, infections, and progressive tissue damage such as gangrene. Without early detection and treatment, minor issues can escalate, sometimes requiring limb salvage procedures or amputation.
Common diabetic foot problems include:
- Peripheral Neuropathy
- Diabetic Foot Ulcers
- Diabetic Foot Infections
- Charcot foot
- Poor Circulation & PAD
- Gangrene
- Limb-threatening wounds requiring limb salvage
Do You Have Symptoms of Diabetic Foot Problems?
- Numbness, tingling, or pain in your feet (neuropathy)
- Cuts, blisters, or sores that don’t heal
- Swelling or redness
- Drainage or odor from a wound (possible infection)
- Blackened tissue or skin changes (possible gangrene)
- Cold feet or delayed healing (possible poor circulation/PAD)
- Changes in skin color or temperature
- Thickened calluses or corns
Diabetic limb preservation may become necessary when diabetic ulcers, foot infections, gangrene, or Charcot deformity threaten the viability of the foot. Without proper care, these conditions may progress to amputation. Regular podiatric evaluation helps identify early warning signs in the skin, bones, nails, nerves, muscles, and blood vessels—allowing timely intervention and prevention.

Common Diabetic Foot Conditions
Diabetes can affect the nerves, circulation, skin, bones, joints, and soft tissues of the feet. Some problems develop gradually, while others can progress quickly. Recognizing these conditions early is an important part of preventing serious complications.
Diabetic Neuropathy
Diabetic neuropathy can cause numbness, tingling, burning, or loss of protective sensation in the feet. When sensation is reduced, you may not notice a blister, cut, pressure injury, or other source of tissue damage. Over time, neuropathy can also contribute to changes in foot structure and increased pressure in certain areas.
Good blood glucose management and regular foot examinations are important for reducing the risk of complications.
Diabetic Foot Ulcers
A diabetic foot ulcer is an open wound that commonly develops because of a combination of reduced sensation, repetitive pressure, deformity, or other underlying problems. Ulcers may occur on the bottom of the foot, toes, or other areas exposed to excessive pressure.
A wound that does not heal, repeatedly returns, or develops redness, drainage, swelling, or increasing warmth requires medical evaluation. An ulcer is not simply a skin problem—the underlying cause needs to be identified and addressed.
Diabetic Foot Infections
A diabetic foot infection can develop when bacteria enter an ulcer, cut, blister, or other area of broken skin. Warning signs may include redness, warmth, swelling, drainage, odor, increasing pain, or rapidly worsening tissue changes.
Infections can spread into deeper soft tissue or bone and may become limb-threatening if not recognized and treated promptly.
Charcot Foot
Charcot foot is a serious complication associated with loss of protective sensation in which the bones and joints of the foot become weakened and progressively deform. The foot may become warm, swollen, unstable, or change shape.
Early recognition is important because continued walking on an affected foot can contribute to further destruction and deformity. A changing foot shape, particularly when accompanied by warmth or swelling, should be evaluated promptly.
Peripheral Arterial Disease (PAD)
Peripheral arterial disease reduces blood flow to the legs and feet and can make wounds more difficult to heal. Diabetes and PAD together substantially increase the risk of non-healing wounds, infection, tissue loss, and amputation.
Signs of significant circulation problems may include a cool foot, changes in skin color, diminished pulses, pain with walking or at rest, or wounds that do not heal. PAD also reflects vascular disease elsewhere in the body and is associated with increased cardiovascular risk.
Gangrene and Tissue Loss
Gangrene occurs when tissue dies because of inadequate blood flow, severe infection, or a combination of both. Black or gray tissue, rapidly worsening wounds, foul odor, or other signs of tissue death require immediate medical attention.
Severe tissue loss may threaten the viability of the foot or limb and requires prompt assessment to determine the cause and the appropriate level of care.
Limb-Threatening Diabetic Foot Disease
Some diabetic foot problems become limb-threatening when infection, inadequate blood flow, tissue loss, bone destruction, severe deformity, or a combination of these conditions places the foot at risk.
These situations require timely diagnosis and coordinated management. The goal is to identify the problem early, preserve as much healthy tissue and function as possible, and determine whether treatment can be provided in the office or requires additional specialty or hospital-based care.

Where Should I Go for a Diabetic Foot Problem?
A diabetic foot problem does not always require the emergency department, but it should not be ignored. The appropriate level of care depends on the severity of the problem, the patient’s risk factors, and whether infection, ischemia, bone involvement, or tissue loss is present. Dr. Hoy can evaluate the foot, establish the diagnosis, determine the appropriate level of care, and coordinate additional specialty or hospital care when necessary.
Preventive Diabetic Foot Care Tips
Keeping your feet healthy is the best way to avoid complications. Dr. Hoy recommends:
- Inspect your feet daily for bruises, cuts, blisters, or swelling.
- Wash and dry your feet carefully, paying attention to areas between toes.
- Wear comfortable, well-fitted shoes and moisture-wicking socks.
- Avoid walking barefoot, even indoors.
- Schedule regular visits with your podiatrist to monitor foot health.
- Maintain healthy blood sugar, cholesterol, and blood pressure levels.
- Have calluses and thickened skin managed by a healthcare professional—self-treatment can increase infection risk
- Wear properly fitted socks and supportive footwear at all times
- Ensure any exercise program is approved by your healthcare provider
Regular monitoring of blood sugar levels, along with proper diet, exercise, and medication adherence, plays a critical role in preventing diabetic foot complications.

Frequently Asked Questions About Diabetic Foot Care
Diabetes can damage nerves and reduce blood circulation in the feet. This combination makes it easier for small injuries—such as cuts, blisters, or pressure points—to go unnoticed and develop into serious infections or ulcers. Regular diabetic foot care helps detect problems early, preventing complications and reducing the risk of amputation.
People with diabetes should watch for the following symptoms:
Numbness or tingling in the feet
Burning or sharp nerve pain
Cuts, blisters, or sores that do not heal
Swelling or redness
Changes in skin color or temperature
Thickened calluses or corns
If you notice any of these symptoms, it’s important to schedule a podiatry evaluation promptly.
Most patients with diabetes should have a comprehensive foot exam at least once per year. However, people with neuropathy, poor circulation, previous ulcers, or other high-risk conditions may need more frequent visits. Regular podiatric care helps identify problems early and prevent serious complications.
Diabetic neuropathy is nerve damage caused by prolonged high blood sugar levels. It often affects the feet and can cause numbness, tingling, burning sensations, or loss of feeling. Because neuropathy reduces the ability to feel injuries, small wounds may go unnoticed and develop into infections or ulcers.
Diabetic foot ulcers are open sores that commonly develop on the bottom of the foot or toes. They often occur due to pressure, poor circulation, or unnoticed injuries. Without proper treatment, ulcers can become infected and may lead to serious complications.
Dr. Hoy provides specialized wound care and treatment to promote healing and prevent infection.
Charcot foot is a serious complication of diabetes that weakens the bones in the foot. This can lead to fractures, joint dislocations, and deformities if not treated early. Early diagnosis and specialized care are essential to stabilize the foot and prevent long-term damage.
Peripheral arterial disease (PAD) occurs when blood flow to the legs and feet is reduced due to narrowed arteries. Poor circulation slows healing and increases the risk of infection and tissue damage. Patients with diabetes and PAD are at higher risk for foot ulcers and amputations.
If infections, ulcers, or severe circulation problems are left untreated, they can lead to tissue damage that may require amputation. However, early treatment and proper diabetic foot care can prevent most amputations. Regular exams, proper footwear, and prompt treatment of injuries greatly reduce this risk.
Simple daily habits can significantly reduce your risk:
Inspect your feet daily for cuts, blisters, or swelling
Wash and dry your feet carefully, especially between toes
Wear properly fitting shoes and moisture-wicking socks
Avoid walking barefoot
Maintain healthy blood sugar levels
Schedule regular foot exams with your podiatrist
Preventive care is one of the most effective ways to protect your feet.
You should schedule an appointment if you notice:
Any wound that is not healing
Redness, swelling, or signs of infection
New numbness or burning pain
Thick calluses or skin breakdown
Changes in foot shape or structure
Early evaluation and treatment can prevent small problems from becoming serious complications.
Diabetic foot risk stratification means determining how likely a person with diabetes is to develop a serious foot problem. Risk is higher when factors such as loss of protective sensation, peripheral arterial disease, a previous foot ulcer or amputation, significant foot deformity, Charcot foot, or recurrent areas of pressure are present.
Identifying these risk factors helps determine how closely your feet should be monitored and when specialist evaluation or preventive care may be appropriate. Someone with a low-risk diabetic foot may need routine preventive care, while a person with neuropathy, poor circulation, a previous ulcer, or other significant risk factors may require more frequent assessment and closer follow-up.
A diabetic foot problem should be evaluated promptly if you develop a new wound, blister, redness, swelling, drainage, increasing warmth, unexplained pain, or a change in the shape of your foot, particularly if you have neuropathy or poor circulation.
Seek urgent medical attention for rapidly spreading redness or swelling, significant drainage or foul odor, black or rapidly dying tissue, severe or rapidly worsening infection, or a foot that suddenly becomes very warm and swollen. Fever or feeling systemically ill in association with a foot wound is also concerning.
If you are unsure how serious a diabetic foot problem is, it is better to have it evaluated rather than waiting for it to worsen. A foot and ankle physician can assess the problem, establish the diagnosis, determine the appropriate level of care, and coordinate additional specialty or hospital care when necessary.
