I always talk to my patients with diabetes about the importance of staying on top of their foot health. It's one of our top office priorities, and that's why we've just introduced a new diabetic foot exam protocol in the office. It's also why we've partnered with Anodyne to provide high-quality, attractive diabetic shoes for our patients. But we can't protect your feet alone, without your help. For that reason, you'll need to take a few different steps. And they happen daily, monthly and annually. Let's look at how to protect your diabetic feet.

3 Ways to Prevent Diabetic Foot Ulcers regular foot exams prevent diabetic foot ulcers

As your Houston podiatrist, I have a few different ways I can protect your feet. But you also have to be part of the process. Here's what I mean.

1. Daily Foot Checks

Right now, you're the best weapon we have against ulcers. When you're at home, I'll ask you to check your feet. Every single day. I want you to look for any changes in your skin appearance. And to watch for any cuts or blisters. (Here's a full guide to help with diabetic foot exams at home.)

Now, I know it can be hard to keep track of minor skin changes. But that's also very important, because the earlier we notice areas of pressure, the easier it is to prevent problems. Need some help tracking your foot progress? Here's an insider tip to help: take a foot selfie every day.

I know, that sounds like a crazy TikTok or Instagram challenge. But here's why it works. When you snap a footie (or foot selfie) daily, using your smartphone, the picture will get a time and date stamp. Then, if you're ever unsure about your foot's appearance? It's easy to scroll back through your photo album, and identify worrying changes.

2. Watch Your Nutrition. 

In new findings released before official publications, researchers found a link between your vitamin D levels and your ulcer risk. Specifically, they learned that levels of vitamin D went down as your ulcer risk went up. And that was especially true for older adults with type II diabetes. What does this mean for you? Well, get your vitamin D levels tested. Then, if they're low, talk to your diabetic care team about the best supplement for your needs. 

3. In-office Exams

If you're already checking your feet every day, great job! But now let's talk about your next step: quarterly comprehensive foot exams in the office.

You may be wondering: why should I come in if my feet look great? Well, here's the deal. Even if you're doing a great job at home, I'm better equipped to monitor hard to reach places like the bottom of your feet. Plus, I have access to high-tech equipment that can spot trouble long before you'd see a visible warning sign.

4. Take your temperature

Monitoring your foot temperature can prevent diabetic foot care


For a while now, we've understood that the temperature of your feet says a lot about brewing ulcers. Back in 2013, a Journal of Foot and Ankle Research study revealed that monitoring your feet's skin temperature could prevent foot ulcers.

Basically, the study proves that higher skin temperature on one foot can predict where an ulcer is about to develop. How? It's pretty simple. Temperature increase is a marker of potentially-dangerous foot inflammation. Which, in turn, often leads to ulcers.

Now, at the time of the study, patients had to keep track of their foot temperature at home. And, when they did, they were more successful at preventing ulcers.

Flash forward almost 10 years, and I'm no longer telling patients to take their foot temperature at home. Instead, I've got some fancy new ways to do that, using the Revealix system. (Not to brag, but that's a pretty big deal. Because our Houston podiatry practice is one of the first in the country to make this system available to patients.)

The process is pretty simple. Revealix uses an external camera. And its linked to an app to record and track data. Now, when I use the camera, it detects any hot spots on your feet. So, once I know about that temperature increase, I can take pressure off the danger zone. (Either with orthotics, diabetic shoes, or a combination of tools.)

Once pressure lowers, the inflammation should go down. And that will reduce your risk of ulcers. But the system is currently only available in our office. So it's important to keep up with your regular appointments.

New Hope for Treating Diabetic Foot Ulcers in Houston

Sadly, even with our best efforts, you may end up with a foot ulcer. Of course, that means you'll immediately need medical attention But you don't have to give up hope. Because we're seeing constant progress in the fight against ulcers. And that includes some exciting new treatment options.

One ulcer treatment I'm watching closely? Researchers from the University of South Australia came up with a new formulation. It's exciting for a few reasons. First, it's not based on antibiotics. So it could be more effective on antimicrobial-resistent ulcers. (In fact, in trials, it proved very good at completely eliminating bacteria.)

Even better? This new treatment could also help us fight another awful infection: COVID-19. Because, as the researchers revealed in the Applied Physics Letters journal, it also seems to inactivate the SARS-Cov-2 virus.

Also on the forefront of diabetic research? Scientists in Ireland are working on a new 3D bioprinting bandage for ulcers, designed to slowly release antibiotics to the wound over a four-week period. While still in development, this bandage would provide a low-cost, effective treatment option for patients with ulcers. 

See? There are so many reasons to feel hopeful for the future. But, in both cases, taking preventive measures is always better than dealing with infection. Even as our tolls for fighting infection get stronger.

Stopping Ulcers Before they Start

When I see diabetic patients in my Houston podiatrist office, I always emphasize the importance of preventative care. Either at home or in my office, regular foot exams are still the best way to maintain your diabetic foot health.

Of course, the work you do at home matters a lot. That's why I always offer you suggestions for critical home inspections and monitoring between your office visits. But I can't say this enough. If you only do home foot checks, you may miss a dangerous warning sign.

That's why I need you to come into our Tanglewood Foot Specialists office. When you do so, I'll use the latest tech to protect your diabetic feet. And, together, we'll take a strong stance against foot ulcers.

Do you know what that means? If you have diabetes in Houston, schedule an appointment with Dr. Andrew Schneider today. It's the best way to start taking proactive steps to protect your feet.
