The Connection Between Diabetes and Foot Health

Diabetes is a condition that affects millions of people worldwide according to Diabetes Australia, and while much attention is given to its impact on organs like the heart and kidneys, foot health often remains an overlooked area. Yet, foot complications are some of the most common issues for those living with diabetes. This blog aims to delve into the critical connection between diabetes and foot health, explore common foot-related problems in diabetics, and provide guidelines on preventive care and treatments.

Why Foot Health is Critical for Diabetics

The Role of Blood Sugar Levels

High blood sugar levels, common in diabetes, can lead to several complications, including nerve damage and poor blood circulation in the feet. Elevated sugar levels can affect the body’s nerves, leading to numbness or insensitivity to pain and temperature changes—factors that make it easier for small injuries to go unnoticed and escalate into severe conditions.

Increased Risk of Infections

Diabetes can impair the immune system, making it more challenging for the body to fight off infections. For the feet, this means that what would usually be a minor cut or scrape could quickly become a more serious issue like cellulitis or a foot ulcer if not properly managed. Moreover, poor circulation makes it harder for blood and nutrients to reach the feet, slowing down the healing process and making infections more likely.

The Australian Podiatry Association states, “Having diabetes may increase your risk of developing diabetes-related complications that include nerve damage called “peripheral neuropathy” or poor circulation in your feet called “peripheral vascular disease.” Nerve damage may affect how you feel pressure or pain and may lead to numbness in your toes or feet. Changes to your circulation may delay your ability to heal any cuts or sores. This may also increase your risk of developing ulcers that may even lead to amputations.” 

Common Foot Problems in Diabetics

Diabetic Neuropathy

One of the most common and serious foot-related issues that diabetics face is diabetic neuropathy.


Diabetic neuropathy is often caused by high blood sugar levels over an extended period. Elevated sugar levels can damage the nerves, particularly in the feet, leading to neuropathy. Additional factors like poor circulation, high levels of blood fats, and even mechanical injury can contribute to the condition.


The symptoms can vary but generally include tingling, burning, or numbness in the feet. For some, these sensations can escalate to severe pain, while others may lose sensation in their feet entirely, making it difficult to detect injuries or temperature changes.

Importance of Regular Foot Exams:

Regular foot exams—both self-checks and examinations by healthcare professionals—are crucial for early detection and effective management. Monitoring for changes can help prevent complications like ulcers and infections that people with neuropathy are at risk for.

Foot Ulcers

Foot ulcers are another serious concern, especially for individuals who have had diabetes for several years.


Foot ulcers can be triggered by a variety of factors. Friction from ill-fitting footwear is a common cause, but other factors can accelerate the development and complicate the healing of these ulcers. Poor blood circulation, often a consequence of diabetes, is a significant risk factor. Diabetic neuropathy can also contribute by making it harder to feel the initial stages of skin breakdown and infection.

Symptoms and Treatment:

These ulcers are open sores that may initially appear as small, discoloured spots but can progress to large, open wounds if not treated promptly. They can easily become infected, leading to more severe complications like cellulitis or osteomyelitis (bone infection). Immediate and specialised treatment is often required to manage foot ulcers effectively. This usually involves a combination of antibiotics, debridement (removal of dead or infected tissue), and off-loading (methods to relieve pressure on the ulcer).

By understanding the causes, symptoms, and necessary precautions associated with diabetic neuropathy and foot ulcers, individuals with diabetes can better manage these conditions. Early detection and timely intervention are key to preventing further complications.

Preventative Foot Care for Diabetics

Routine Foot Checks

Consistent self-examination of your feet is essential when you’re living with diabetes. Check for any cuts, sores, redness, swelling, or nail problems. Ideally, this should be done daily to catch issues before they become severe. Use a mirror to inspect the soles and between the toes, and consider involving a family member if it’s challenging to do it yourself.

Proper Footwear

Choosing the right shoes and socks can make a world of difference in diabetic foot care. Shoes should offer excellent support, have a broad toe box, and be made from materials that allow your feet to breathe. Socks should be moisture-wicking to keep your feet dry and reduce the risk of fungal infections. Custom orthotics can provide extra support and cushioning.

Treatment Options for Diabetic Foot Conditions

Topical Treatments

Various topical treatments such as creams, ointments, and balms are available to manage diabetic foot problems. Products containing urea or lactic acid are often recommended for dry skin. If a fungal infection like athlete’s foot is present, antifungal creams are generally the first line of treatment. Always consult a healthcare provider for proper diagnosis and treatment recommendations tailored to your condition.

Prescription Medications

In some cases, topical treatments might not be enough, and prescription medications are required. Antibiotics may be prescribed for bacterial infections, and specific pain medications may be recommended for relief from neuropathic pain. Some medications also aim to improve blood circulation in the feet. Again, a consultation with a healthcare provider is essential for accurate diagnosis and appropriate medication.

Living with Diabetes: Real-life Tips for Foot Care

Maintaining healthy feet is an ongoing process, especially for individuals with diabetes. The following sections will offer practical tips for daily foot care and safe physical activities.

Daily Routine

Foot care should become as routine as brushing your teeth when you’re living with diabetes. Start your day by washing your feet with lukewarm water and mild soap. Dry them thoroughly, especially between the toes, to prevent fungal infections. Apply a moisturiser, but avoid the area between the toes. End your day with a quick foot check for any abnormalities, like cuts, blisters, or redness. Report any concerning findings to your healthcare provider immediately.

Physical Activity

Staying active is crucial for overall health, including foot health, but physical activities can pose risks for people with diabetes. Always wear athletic shoes that fit well and provide good support. Avoid going barefoot, even in places like the beach or swimming pool, to reduce the risk of injury. After exercising, make sure to inspect your feet for any signs of blisters, redness, or other issues. Consult your healthcare provider for tailored advice on safe and appropriate physical activities for your condition.

By adopting these real-life tips into your daily routine and being mindful during physical activities, you can significantly minimise the risks of severe foot complications related to diabetes.

How Podiatrists Help Diabetes Patients

When it comes to managing foot problems associated with diabetes, consulting a podiatrist can make a significant difference in both the quality of care and the outcomes you experience. Here’s how a podiatrist can specifically help:

Comprehensive Foot Exams

One of the key services offered by podiatrists is comprehensive foot examinations. These exams are designed to identify any abnormalities—like corns, calluses, ulcers, or fungal infections—that could potentially lead to severe complications. The podiatrist can also assess nerve health and blood circulation, essential factors in diabetic foot care.

Customised Treatment Plans

Based on the results of the foot exam and your medical history, a podiatrist can create a customised treatment plan. This might include prescription medications, topical treatments, or even surgical interventions for severe cases such as non-healing ulcers or gangrene.

Specialised Procedures

Some foot issues may require specialised procedures that general healthcare providers are not equipped to handle. For example, debridement (removal of dead skin or infected tissue), toenail removal, or surgical interventions to correct deformities like Charcot foot are services offered by podiatrists with specialised training.

Custom Orthotics

A podiatrist can also design custom orthotic devices tailored to your feet and specific conditions. These devices can help redistribute weight, relieve pressure points, and improve alignment, all crucial factors in managing diabetic foot problems.

Ongoing Management and Education

Beyond the initial diagnosis and treatment, a podiatrist can also offer guidance for ongoing care, including self-examination tips, footwear recommendations, and activity modifications. They can educate you on how to recognise early signs of foot issues, which is crucial for timely intervention and can often prevent minor problems from turning into major complications.

Coordination with Other Healthcare Providers

Your podiatrist can also coordinate care with your general physician or endocrinologist, ensuring that your diabetic foot care is integrated into your overall diabetes management plan. They can update these providers about changes in your foot health, ensuring a holistic approach to your diabetes care.

By offering specialised services, tailored treatments, and a wealth of experience, a podiatrist is an indispensable part of the healthcare team for anyone managing diabetes. Their expertise can help you navigate the complex landscape of diabetic foot care, ultimately leading to better outcomes and improved quality of life.

Emergency Situations: When to Seek Immediate Care

Being informed about emergency situations regarding diabetic foot care is crucial, especially because some complications can escalate quickly. Identifying red flags early on and knowing what emergency treatment protocols entail can be life-saving.

Red Flags

When managing diabetes, it’s important to know which symptoms should trigger immediate medical attention. Diabetic foot problems can escalate quickly, so awareness and rapid response are key. Here are some alarming symptoms to watch for:

  • Sudden Intense Pain: Any sudden, unexplained, or intense pain in the feet is a definite red flag.
  • Signs of Severe Infection: High fever, chills, and red streaks emanating from a wound are signs of a severe, possibly systemic, infection that requires immediate medical attention.
  • Changes in Color or Temperature: Sudden changes in the colour or temperature of your foot could indicate an issue with blood circulation or an impending infection. If your foot turns blue, pale, or cold to the touch, seek emergency care immediately.
  • Oozing Sores or Increasing Swelling: Any sore that begins to ooze pus or causes increased swelling in the area is of concern.
  • Loss of Sensation: A sudden loss of feeling in the foot or leg, especially when combined with other symptoms, needs immediate evaluation.

If you experience any of these symptoms, it is crucial to seek emergency medical care as quickly as possible.

Emergency Treatment Protocols

If your foot problem requires emergency medical attention, you should know what to expect regarding treatment. Timely and appropriate interventions can often prevent complications that could otherwise lead to severe outcomes like amputation.

  • Immediate Assessment: Upon arrival, healthcare providers will quickly assess your condition, likely conducting blood tests and imaging studies, like X-rays or MRIs, to understand the severity of the issue.
  • IV Antibiotics: For severe infections, intravenous antibiotics are usually administered promptly to control the infection.
  • Surgical Interventions: In certain severe cases, surgical intervention may be required. This could involve debridement (removal of dead or infected tissue), incision and drainage of an abscess, or in extreme cases, amputation.
  • Blood Sugar Management: Your blood sugar levels will be closely monitored and managed, as unstable levels can exacerbate the problem.
  • Coordination of Care: If you’re hospitalised for a foot emergency, your care will likely involve a multidisciplinary team that includes your endocrinologist, a podiatrist, and possibly vascular surgeons or infectious disease specialists.

Long-term Outcomes and Prognosis

Managing diabetes is a long-term commitment, and the same applies to diabetic foot care. The prognosis for individuals who proactively manage their foot health is generally good, provided they also manage their blood sugar levels effectively. However, failure to adhere to proper foot care can lead to chronic conditions, complications, and in severe cases, limb amputations.

Importance of Consistent Care

Consistent, proactive care cannot be emphasised enough when discussing long-term outcomes. Those who engage in regular foot check-ups, follow a healthcare provider’s advice, and manage their diabetes well often have fewer complications and a better quality of life. Ongoing care allows for early detection of any abnormalities or complications, leading to quicker interventions and better outcomes.

Patients who neglect foot care or don’t manage their diabetes effectively are at a higher risk for severe foot ulcers, infections, and even amputations. Consistent care is not just about daily routines but also involves regular consultations with healthcare providers, including podiatrists and endocrinologists, for comprehensive examinations and treatment plans.

Conclusion: Empowering Diabetics for Better Foot Health

The connection between diabetes and foot health is undeniable and crucial to the well-being of anyone managing this chronic condition. With complications ranging from diabetic neuropathy to foot ulcers, the stakes are high for those who overlook this important aspect of diabetes care. However, the good news is that with early detection, proper preventative measures, and effective treatment strategies, many of these complications can be minimised or even entirely avoided.

Your feet are your foundation, and for those with diabetes, taking extra precautions can make a world of difference. From daily self-checks to regular consultations with healthcare providers such as podiatrists, ongoing care is the cornerstone for long-term positive outcomes.
