For the more than 37 million Americans living with diabetes, foot health is not a seasonal concern. It is a year-round priority. But summer introduces a unique set of risks that can turn a minor foot problem into a serious medical emergency faster than at any other time of year.

At Diablo Foot & Ankle, our podiatrists in Walnut Creek, Antioch, and San Ramon work with diabetic patients every day. We understand the specific challenges that summer presents, and we want to make sure every diabetic patient in the East Bay has the information they need to protect their feet through the warmer months.

Why Diabetes Makes Foot Health So Critical

To understand why diabetic foot care is so important, it helps to understand what diabetes does to the feet over time.

Peripheral Neuropathy: High blood sugar levels damage the nerves throughout the body, with the longest nerves, those that reach the feet, being affected first. This nerve damage, called peripheral neuropathy, causes a loss of sensation in the feet. Patients may not feel cuts, blisters, burns, or pressure injuries. A small wound that would be immediately noticeable and painful for a non-diabetic person can go undetected for days or weeks in a diabetic patient, giving it time to become infected.

Peripheral Arterial Disease: Diabetes also damages blood vessels, reducing circulation to the extremities. Poor circulation means that wounds heal more slowly and that the immune system has a harder time fighting infections in the feet and lower legs. Even minor infections can become serious when the blood supply is compromised.

Increased Infection Risk: The combination of reduced sensation, poor circulation, and elevated blood sugar levels, which create an environment where bacteria and fungi thrive, makes diabetic patients significantly more susceptible to foot infections. What begins as a small blister or cut can progress to a deep tissue infection, osteomyelitis (bone infection), or in severe cases, may require amputation.

These are not rare outcomes. Diabetes is the leading cause of non-traumatic lower limb amputations in the United States. The vast majority of these amputations are preceded by a foot ulcer, and the vast majority of foot ulcers are preventable with proper care and regular podiatric monitoring.

Summer-Specific Risks for Diabetic Patients

Summer creates several additional risk factors that diabetic patients in Walnut Creek, Antioch, and San Ramon need to be aware of.

Heat and Swelling: Hot weather causes blood vessels to dilate and fluid to accumulate in the lower extremities. For diabetic patients with compromised circulation, this swelling can be more pronounced and can increase pressure inside shoes, leading to pressure injuries and blisters that go unnoticed due to neuropathy.

Burns: Diabetic patients with neuropathy may not feel the heat of hot pavement, sand, or pool decks. Walking barefoot on a surface that has been heated by the summer sun can cause serious burns that the patient does not notice until significant tissue damage has occurred. This is one of the most preventable and most serious summer foot injuries in diabetic patients.

Infections from Water Exposure: Swimming pools, lakes, and other bodies of water harbor bacteria and fungi. Any small cut, blister, or break in the skin on a diabetic patient's foot can serve as an entry point for infection when exposed to these environments.

Dehydration: Summer heat increases the risk of dehydration, which can cause blood sugar levels to rise. Elevated blood sugar impairs wound healing and immune function, compounding the risks already present.

Footwear Changes: The switch to sandals and open-toe shoes in summer, while reducing the risk of moisture buildup inside closed shoes, exposes the feet to more trauma. Straps can rub and cause blisters; open toes are more vulnerable to stubbing and injury.

Essential Summer Foot Care Guidelines for Diabetic Patients

Our podiatrists recommend the following practices for all diabetic patients during the summer months.

Never go barefoot outdoors. This is the single most important rule. Always wear shoes or sandals, even in your own backyard, on the beach, or at the pool. The risk of stepping on something sharp or burning your feet on hot pavement is too high.

Inspect your feet every day. Use a mirror to check the bottoms of your feet if you cannot see them easily. Look for cuts, blisters, redness, swelling, warmth, or any changes in skin or nail color. If you notice anything unusual, contact your podiatrist promptly.

Choose footwear carefully. Sandals for diabetic patients should have a wide toe box, a cushioned footbed, adjustable straps, and a firm sole. Avoid sandals with straps that cross over bony prominences, as these are common sites for pressure injuries. Ask your podiatrist about diabetic-friendly footwear options.

Test water temperature before entering. Before stepping into a pool, bath, or any body of water, test the temperature with your elbow or a thermometer. Never assume the temperature is safe based on how it looks.

Keep feet moisturized but not between the toes. Apply a diabetic-formulated foot cream to the tops and bottoms of your feet daily to prevent dryness and cracking. Avoid applying moisturizer between the toes, as excess moisture in this area promotes fungal growth.

Manage blood sugar levels. Good glycemic control is the foundation of diabetic foot health. Elevated blood sugar impairs nerve function, circulation, and wound healing. Work closely with your primary care physician or endocrinologist to keep your levels within your target range.

Schedule regular podiatric check-ups. Most diabetic patients should see a podiatrist at least once every three to six months, even when there are no active problems. Regular professional foot exams allow for early detection of neuropathy, circulation changes, and developing wounds before they become serious.

Sanexas Electrotherapy for Diabetic Neuropathy

One of the most challenging aspects of diabetic foot care is managing peripheral neuropathy. The numbness, tingling, burning, and pain associated with neuropathy significantly affects quality of life and increases the risk of undetected foot injuries.

At Diablo Foot & Ankle, we offer Sanexas electrotherapy, an advanced electric cell signaling treatment that has shown significant results in reducing neuropathy symptoms. Sanexas delivers precise electrical signals that stimulate nerve function, improve circulation, and reduce pain. Many of our patients with diabetic neuropathy report meaningful improvements in sensation and a reduction in the burning and tingling sensations that make daily life difficult.

Sanexas therapy is available at all three of our locations in Walnut Creek, Antioch, and San Ramon, and it is one of the services that sets Diablo Foot & Ankle apart from other podiatry practices in the East Bay.

Wound Care and Ulcer Prevention

If you develop a wound on your foot, the speed of your response matters enormously. For diabetic patients, the window between a minor wound and a serious infection can be very short.

At Diablo Foot & Ankle, we provide comprehensive wound care services including debridement, advanced wound dressings, offloading devices to reduce pressure on the wound, and coordination with vascular specialists when circulation issues are contributing to delayed healing. Our goal is to close wounds quickly and prevent complications.

If you notice any wound, blister, or area of skin breakdown on your foot, do not wait to see if it heals on its own. Call our office immediately at (925) 464-1982 and we will see you as promptly as possible.
