Top Causes of Foot Ulcers and How South Chicago Podiatrists Can Help

Foot ulcers are more than just a skin issue—they’re a warning sign. Often linked to underlying conditions like diabetes or poor circulation, these open sores on the feet can lead to serious complications if not treated properly. In fact, untreated ulcers can lead to infections, hospitalizations, and even amputations.

At American Surgeons Group, our team in South Chicago specializes in diagnosing and treating foot ulcers before they become severe. Understanding what causes them is the first step in preventing them—and knowing when to seek podiatric help can make all the difference in healing.

What Exactly Is a Foot Ulcer?

A foot ulcer is an open sore or wound that usually occurs on the bottom of the foot, often under pressure points like the heel or ball. These ulcers can be shallow or deep and may expose layers of skin, tissue, or even bone. They often go unnoticed in the early stages, especially by patients with nerve damage (neuropathy), which is why proactive foot care is crucial.

Top Causes of Foot Ulcers

Here are the most common causes of foot ulcers we see in our South Chicago clinic:

1. Diabetes and Neuropathy

Diabetic patients are especially prone to foot ulcers due to neuropathy—nerve damage that reduces the ability to feel pain or discomfort. When you can’t feel irritation from tight shoes, a blister, or a cut, the wound may worsen unnoticed. Poor circulation in diabetic individuals also delays healing, making the situation more complex.

2. Peripheral Arterial Disease (PAD)

PAD restricts blood flow to the extremities, especially the feet and toes. Reduced circulation limits oxygen and nutrient delivery, which are essential for wound healing. PAD not only makes ulcers more likely to form but also much harder to heal.

3. Pressure and Friction

For patients with mobility issues or those who are bed-bound or use wheelchairs, constant pressure or friction on the feet can cause skin breakdown. This is especially true for people wearing ill-fitting shoes or orthotics. Over time, this repeated stress leads to ulcers.

4. Infections

Even small cuts, ingrown toenails, or fungal infections can escalate into foot ulcers if left untreated. Infections may spread quickly in people with compromised immune systems or underlying conditions, leading to deeper wounds and more serious health risks.

5. Poor Footwear and Foot Deformities

Bunions, hammertoes, or flat feet can create pressure points that lead to rubbing and eventually skin breakdown. Without custom footwear or padding, these areas are at higher risk for ulceration.

How South Chicago Podiatrists Can Help

At American Surgeons Group, we approach ulcer care from every angle—prevention, early detection, advanced wound treatment, and long-term maintenance. Here’s how we help:

✅ Thorough Evaluation and Diagnostics

We assess circulation, nerve function, and pressure points using state-of-the-art tools. Early detection of risks allows us to create a custom care plan before ulcers form.

✅ Wound Debridement and Dressing

If a wound is already present, we use precise methods to clean and remove dead tissue, promote healing, and reduce infection risks. Specialized wound dressings are applied to protect and nourish the skin.

✅ Diabetic Foot Care Plans

For diabetic patients, we offer regular checkups, education on daily foot care, and support for blood sugar management—all of which are essential to ulcer prevention.

✅ Custom Orthotics and Footwear Guidance

We provide custom orthotics and advice on proper footwear to relieve pressure points and prevent skin breakdown, especially for those with deformities or previous ulcers.

✅ Patient Education and Follow-Up

Ongoing care is key. We teach our patients how to inspect their feet daily, recognize early signs of trouble, and know when to call us. Our follow-up care ensures long-term healing.
