Diabetes and Feet: Important Diabetic Foot Care Considerations

Posted on February 28th, 2024.

Living with diabetes entails a series of diligent considerations, especially when it comes to foot health. Diabetes can significantly impact the health of your feet, leading to various complications if not managed effectively.

In this blog post, we'll delve into the crucial aspects of diabetic foot care, highlighting the importance of proactive measures to maintain optimal foot health.

Diabetic Foot Care Considerations

The Impact of Diabetes on Foot Health

Diabetes, a chronic metabolic disorder characterised by elevated blood sugar levels, can have far-reaching consequences on various parts of the body, including the feet. Individuals living with diabetes often face a myriad of foot-related complications that require careful management and attention.

Diabetic Neuropathy: Nerve Damage and Sensory Loss

One of the most common and potentially debilitating complications of diabetes is diabetic neuropathy. This condition occurs due to prolonged exposure to high blood sugar levels, leading to damage to the nerves, particularly those in the feet. Diabetic neuropathy can manifest in various ways, including:

• Peripheral Neuropathy: This type of neuropathy affects the peripheral nerves, causing symptoms such as numbness, tingling, or burning sensations in the feet. As the condition progresses, individuals may experience a loss of sensation, making them vulnerable to injuries that go unnoticed.
• Autonomic Neuropathy: Autonomic neuropathy affects the nerves that control involuntary bodily functions, such as sweating and blood pressure regulation. In the feet, autonomic neuropathy can result in dry skin, excessive sweating, and changes in blood flow, increasing the risk of foot complications.

Foot Ulcers: Wounds That Require Vigilant Care

Foot ulcers are a common complication of diabetes, particularly in individuals with neuropathy or poor circulation. These ulcers are open wounds or sores that develop on the feet, often due to pressure, trauma, or repetitive friction.

Diabetic foot ulcers require prompt treatment and careful management to prevent complications such as infection and tissue damage.

Infections: Heightened Vulnerability and Risks

Due to compromised immune function and impaired wound healing, individuals with diabetes are more susceptible to infections, particularly in the feet. Even minor injuries or cuts can quickly escalate into serious infections if left untreated. Common foot infections in diabetics include:

• Cellulitis: A bacterial skin infection that can spread rapidly if not promptly treated, causing redness, swelling, and warmth in the affected area.
• Osteomyelitis: An infection of the bone that can occur when foot ulcers penetrate deep into the tissue, leading to severe pain, swelling, and potentially permanent damage if left untreated.

Peripheral Artery Disease (PAD): Impaired Blood Flow and Complications

Peripheral artery disease (PAD) is a circulatory condition that occurs when narrowed arteries restrict blood flow to the extremities, including the feet. Individuals with diabetes are at an increased risk of developing PAD due to factors such as high cholesterol, hypertension, and insulin resistance. PAD can exacerbate foot problems in diabetics by:

• Impairing Wound Healing: Reduced blood flow deprives the feet of essential nutrients and oxygen, slowing down the body's ability to heal wounds and injuries.
• Increasing Infection Risk: Poor circulation compromises the immune response, making it harder for the body to fight off infections in the feet and lower limbs.

Foot Deformities

Over time, diabetes can contribute to structural changes in the feet, leading to deformities that affect mobility and increase the risk of complications. Common foot deformities associated with diabetes include:

• Charcot Foot: A condition characterised by weakened bones and joint instability, often resulting from nerve damage and repetitive trauma. Charcot foot can cause the arch of the foot to collapse, leading to deformity and instability.
• Claw Toe: A deformity in which the toes bend downward at the middle joint, causing the toes to resemble claws. Claw toe can result from nerve damage and muscle imbalances in the feet, making it difficult to wear shoes comfortably and increasing the risk of pressure ulcers.

The Role of Preventive Foot Care

Given the potential risks and complications associated with diabetes-related foot issues, preventive foot care is essential for diabetics. By adopting simple yet effective foot care practices, individuals can reduce the likelihood of developing complications and maintain overall foot health. Some key aspects of preventive foot care for diabetics include:

Daily Foot Inspections

Regularly inspecting the feet for any signs of injury, irritation, or abnormalities is critical for early detection and prompt intervention. Diabetics should pay close attention to changes in skin colour, temperature, texture, and the presence of cuts, blisters, or sores.

Proper Hygiene and Moisturization

Keeping the feet clean and moisturised helps prevent dry skin and reduces the risk of cracks or fissures that can lead to infection. Diabetics should wash their feet daily with mild soap and lukewarm water, ensuring thorough drying, especially between the toes.

Nail Care

Trimming toenails properly and avoiding ingrown toenails is essential for preventing infections and other foot problems. Diabetics should cut nails straight across and file any sharp edges to avoid injuring the surrounding skin.

Avoiding Barefoot Walking

Walking barefoot increases the risk of injuries and exposes the feet to potential hazards such as sharp objects or hot surfaces. Diabetics should always wear shoes or slippers, even indoors, to protect their feet from injury.

Seeking Professional Care

In addition to practising preventive foot care at home, diabetics should also seek regular professional care from healthcare providers specialising in diabetic foot management. Regular foot examinations, screenings for neuropathy and vascular disease, and expert guidance on foot care are essential components of comprehensive diabetic care.

The Importance of Footwear for Diabetics

Foot problems are common among individuals with diabetes, making proper footwear selection a critical aspect of foot care. The right shoes can help protect the feet from injuries, provide support and stability, and promote proper circulation. Conversely, ill-fitting or inappropriate footwear can increase the risk of foot ulcers, infections, and other complications. When choosing footwear for diabetics, it's essential to consider the following factors:

Comfort

Comfort should be the top priority when selecting footwear for diabetics. Shoes should fit well and feel comfortable from the moment you put them on, with no tightness or pressure points. Look for shoes with ample cushioning and padding to provide support and reduce friction.

Protection

Diabetics should choose shoes that offer adequate protection for the feet. Closed-toe shoes with a roomy toe box help shield the feet from injuries and provide support and stability. Avoid shoes with seams, rough edges, or tight-fitting areas that can cause rubbing and irritation.

Support

Proper arch support is essential for individuals with diabetes, especially those with neuropathy or foot deformities. Look for shoes with built-in arch support or consider using orthotic inserts to provide additional support and alignment for the feet.

Breathability

Breathable materials such as leather or mesh allow air to circulate around the feet, reducing the risk of moisture buildup and bacterial growth. Proper ventilation helps keep the feet dry and comfortable, minimising the risk of fungal infections and skin irritations.

Adjustability

Diabetic feet can swell throughout the day, so it's essential to choose shoes that offer adjustability to accommodate changes in foot size. Look for shoes with adjustable closures such as laces, Velcro straps, or buckles that allow you to customise the fit for optimal comfort and support.

Tips for Selecting Diabetic-Friendly Footwear

When shopping for footwear as a diabetic, consider the following tips to ensure you choose the right pair:

Get Properly Fitted

Visit a reputable shoe store with trained staff who can measure your feet and offer expert guidance on proper shoe sizing and fit. Avoid purchasing shoes online without trying them on first, as sizing can vary between brands and styles.

Shop Later in the Day

Feet tend to swell throughout the day, so it's best to shop for shoes in the afternoon or evening when your feet are at their largest. This ensures you get a more accurate fit and helps prevent shoes from feeling too tight or restrictive.

Test for Comfort

Walk around the store in potential footwear options to assess comfort, support, and stability. Pay attention to any areas of rubbing or discomfort and make sure there's enough room for your toes to wiggle comfortably.

Consider Specialized Footwear

In some cases, individuals with diabetes may require specialised footwear to accommodate foot deformities, ulcers, or other specific needs. Consult with a podiatrist or foot specialist for recommendations on orthopaedic shoes or custom-made inserts.

The Role of Exercise in Managing Diabetes

Exercise is a powerful tool in managing diabetes, offering a multitude of benefits for both physical and mental health. For individuals living with diabetes, incorporating regular physical activity into their routine can play a significant role in controlling blood sugar levels, improving insulin sensitivity, and reducing the risk of complications associated with the condition.

Benefits of Exercise for Diabetes Management

Regular exercise offers a wide range of benefits for individuals with diabetes, including:

Blood Sugar Control

Physical activity helps lower blood sugar levels by increasing the body's sensitivity to insulin, the hormone responsible for regulating blood sugar. Exercise encourages glucose uptake by muscle cells, effectively reducing blood sugar levels and improving overall glycemic control.

Weight Management

Maintaining a healthy weight is crucial for managing diabetes, as excess body fat can contribute to insulin resistance and exacerbate blood sugar imbalances. Exercise helps promote weight loss or weight maintenance by burning calories and increasing metabolism, leading to improved insulin sensitivity and better blood sugar control.

Cardiovascular Health

Diabetes is associated with an increased risk of cardiovascular disease, including heart attacks, strokes, and peripheral artery disease. Regular exercise strengthens the heart and cardiovascular system, lowers blood pressure and cholesterol levels, and reduces the risk of cardiovascular complications in individuals with diabetes.

Stress Reduction and Mental Well-Being

Exercise has been shown to reduce stress levels, improve mood, and alleviate symptoms of depression and anxiety, which are common comorbidities in individuals with diabetes. Engaging in physical activity releases endorphins, the body's natural feel-good hormones, promoting a sense of well-being and mental clarity.

Types of Exercise for Diabetes Management

When it comes to managing diabetes through exercise, incorporating a variety of activities into your routine is key. Here are some types of exercise that are particularly beneficial for individuals with diabetes:

Aerobic Exercise

Aerobic exercise, also known as cardio or endurance exercise, involves activities that increase heart rate and breathing rate over an extended period. Examples include walking, jogging, cycling, swimming, dancing, and aerobic classes. Aim for at least 150 minutes of moderate-intensity aerobic exercise per week, spread out over several days.

Strength Training

Strength training, also known as resistance or weight training, involves exercises that target specific muscle groups using resistance from weights, resistance bands, or body weight. Strength training helps build muscle mass, improve metabolism, and increase insulin sensitivity. Aim for two to three sessions of strength training per week, focusing on major muscle groups.

Flexibility and Balance Exercises

Flexibility and balance exercises help improve range of motion, joint flexibility, and stability, reducing the risk of falls and injuries. Examples include yoga, tai chi, and stretching exercises. Incorporate flexibility and balance exercises into your routine at least two to three times per week, focusing on stretching major muscle groups and practising balance poses.

Tips for Getting Started with Exercise

If you're new to exercise or haven't been active in a while, it's essential to start slowly and gradually increase the intensity and duration of your workouts. Here are some tips to help you get started with exercise:

• Consult with your healthcare provider before starting any exercise program, especially if you have any pre-existing health conditions or concerns.
• Choose activities that you enjoy and that fit your lifestyle and fitness level. Remember that physical activity doesn't have to be formal exercise—it can include everyday activities such as gardening, cleaning, or taking the stairs.
• Start with short bouts of activity and gradually increase the duration and intensity over time. Aim for at least 30 minutes of moderate-intensity exercise on most days of the week.
• Listen to your body and take breaks as needed. If you experience any pain, dizziness, or discomfort during exercise, stop and rest.
• Stay hydrated by drinking plenty of water before, during, and after exercise, especially in hot weather or during intense workouts.
• Monitor your blood sugar levels before, during, and after exercise, especially if you take insulin or other medications that can affect blood sugar.
