If you’re living with diabetes, you probably know it can affect your feet. But there’s one complication most people haven’t heard of—and catching it early makes all the difference.

It’s called Charcot foot.
And while it might sound unfamiliar, it’s something we take very seriously in podiatry—because when it goes untreated, it can lead to major changes in how your foot looks, feels, and functions.

Let’s walk through what it is, how to spot it early, and why fast action matters.

What Is Charcot Foot, Anyway?

Charcot foot (pronounced “shar-ko”) is a condition that causes the bones in your foot to weaken and break down. It usually happens in people with diabetic neuropathy—nerve damage that makes it harder to feel pain, temperature, or injury.

Without those pain signals, a person can keep walking on a foot that’s already injured… and not even realize it.

Over time, this leads to:

• Bone fractures

• Dislocation of joints

• Collapse of the foot’s arch

• A “rocker-bottom” foot shape

It might sound dramatic, but here’s the good news: if caught early, Charcot foot can be treated. You can avoid long-term damage, surgery, or even amputation. The key is not waiting too long.

Early Signs to Watch For

Charcot foot usually starts out looking like a mild injury—nothing that seems too concerning. But trust your instincts. If something feels off, especially in a foot with neuropathy, don’t ignore it.

Here’s what to look for:

• Redness or warmth in one foot (but not the other)

• Swelling that doesn’t go away

• Foot feels warmer than usual to the touch

• You’re having trouble fitting into your shoes

• A sudden change in the shape or arch of your foot

Sometimes there’s no pain at all. That’s why it’s so important to check your feet daily if you have diabetes.

Why Fast Action Matters

If we catch Charcot foot in its early stages, we can often stop the damage before it gets serious. Treatment usually involves:

• Taking pressure off the foot using a special boot or cast

• Resting the foot completely so the bones can heal

• Monitoring with X-rays or imaging to track progress

Waiting too long can lead to permanent deformity, trouble walking, chronic wounds, or even infection and amputation. No one wants that—and it’s often avoidable with timely care.
