Diabetic foot ulcers can lead to serious complications if left untreated, including infections, tissue damage, and even amputation. Acting quickly when you notice early warning signs can prevent these outcomes. Here are the 7 key signs to watch for:
- Increased Pain: Sudden or worsening pain around the ulcer.
- Redness and Swelling: Expanding redness and persistent swelling.
- Warmth Around the Ulcer: The area feels hotter than surrounding skin.
- Foul Odor: Strong, unpleasant smell from the wound.
- Discharge: Thick, yellow, green, or blood-streaked fluid.
- Fever or Chills: Signs the infection may be spreading.
- Slow Healing: Little to no improvement in the wound over time.
What to Do: Regularly check your feet, follow proper wound care, and maintain stable blood sugar levels. If you notice any of these symptoms, consult a doctor immediately to avoid complications. Early treatment can prevent up to 85% of diabetes-related amputations.
Diabetic Foot Ulcer 101
What Are Diabetic Foot Ulcers?
Diabetic foot ulcers are open wounds that often begin as small injuries, like cuts or blisters. However, due to complications from diabetes, these minor issues can quickly escalate into more serious problems [4][1].
Definition of Diabetic Foot Ulcers
These ulcers typically form on areas of the foot that experience the most pressure, such as the balls of the feet or under the big toes. Friction and pressure from walking or standing often contribute to their development [4][1].
Why Diabetics Are More Prone to Foot Ulcers
Diabetics face a higher risk of foot ulcers due to a combination of factors stemming from the condition:
- Neuropathy: About 60% of diabetics experience nerve damage, which reduces sensation in the feet. This makes it easier to overlook small injuries [2].
- Poor Circulation: High blood sugar damages blood vessels, limiting the delivery of oxygen and nutrients needed for wound healing [4][3].
- Weakened Immunity: Diabetes can impair the body’s ability to fight infections, allowing minor wounds to develop into severe issues.
Risks of Untreated Ulcers
If left untreated, diabetic foot ulcers can lead to infections, damage to deeper tissues, or even gangrene. In severe cases, amputation may be necessary. Early detection and treatment are crucial to avoiding these outcomes [1][2].
Stage | Complication | Potential Outcome |
---|---|---|
Early | Local Infection | Can be managed with wound care |
Intermediate | Deep Tissue Infection | May need specialized treatment |
Advanced | Gangrene | Could result in amputation |
Understanding how and why these ulcers develop is a key step in managing the condition. Up next, we’ll cover the warning signs of infection so you can take action promptly.
7 Signs of Infected Diabetic Foot Ulcers
Spotting the early signs of infection in diabetic foot ulcers is critical to avoiding serious health issues. Here’s what to watch for:
1. Increased Pain
If the pain around the ulcer becomes more intense or constant, it’s time to act. While some discomfort is expected, a sharp rise in pain – especially if it feels throbbing or tender to touch – could point to an infection [1][3].
2. Redness and Swelling
Infections often cause noticeable redness and swelling that extends beyond the ulcer itself.
Characteristic | Normal Irritation | Signs of Infection |
---|---|---|
Color | Light pink | Intense redness |
Area | Localized | Expanding redness |
Duration | Temporary | Persistent |
Touch | Minimal tenderness | Significant pain |
3. Warmth Around the Ulcer
Feel the area around the ulcer and compare it to the same spot on the other foot. A warmer temperature near the ulcer could be a sign of infection [1][3].
4. Foul Odor
A strong, unpleasant smell from the ulcer is often due to bacterial growth. This odor may come with discharge, which is another red flag [4][3].
5. Discharge
Infected ulcers can release thick, cloudy fluid, yellow or green pus, or blood-streaked discharge. Any sudden changes in the amount, color, or texture of the discharge should be checked by a doctor immediately [4][1].
6. Fever or Chills
A fever or chills could mean the infection is spreading, signaling a more serious problem. Be alert for:
- A temperature over 100.4°F (38°C)
- Unexplained chills
- General feelings of being unwell [5]
7. Slow Healing
Healthy ulcers should show steady improvement. If healing slows down, the ulcer gets bigger or deeper, or the edges worsen, it’s a warning sign of infection [3][5].
“A multidisciplinary team, including diabetes and wound nurses, general practitioners, diabetologists, and vascular consultants, should assess every patient with diabetes and an active diabetic foot ulcer” [5].
Catching these signs early can make a big difference. Up next, we’ll cover when it’s time to seek expert medical care.

Wound Care NYC
Wound Care NYC offers tailored treatment plans, advanced debridement methods, and infection management, along with patient education to aid healing and reduce future risks. Their services include oxygen therapy, specialized wound cleaning, and strict infection control measures.
This level of care is especially critical since diabetic foot infections are one of the leading reasons for hospitalizations among diabetes patients [5]. The center works with major insurance providers to help patients get the most out of their coverage.
Delaying treatment can lead to serious complications. While expert care is essential, taking preventive steps is the best way to manage diabetic foot ulcers effectively.
Preventing Infections in Diabetic Foot Ulcers
Once you’ve identified warning signs, the next step is focusing on prevention to avoid complications from diabetic foot ulcers.
Daily Foot Care
Taking care of your feet every day is crucial for keeping infections at bay. Use good lighting and a mirror to check all areas, especially those tough-to-see spots.
Daily Care Step | Why It Matters | When to Do It |
---|---|---|
Inspect Your Feet | Spot cuts, blisters, or redness | Morning and evening |
Clean Gently | Remove bacteria and debris | During your shower/bath |
Apply Moisturizer | Avoid dry, cracked skin | After cleaning, when dry |
Check Your Footwear | Look for objects or damage | Before putting on shoes |
Proper Wound Care
Stick to your healthcare provider’s instructions for cleaning and dressing any wounds. Keep an eye on the healing process, and take note of any new drainage, discoloration, or warmth around the ulcer. If you notice these changes, seek medical attention right away.
Managing Blood Sugar
Keeping your blood sugar levels in check is critical for healing and avoiding infections. This involves regular monitoring, taking prescribed medications, eating balanced meals, and staying active. High blood sugar can slow down your body’s ability to heal and raise the risk of infections [2].
Conclusion
Understanding the seven key signs of an infected diabetic foot ulcer – pain, redness, warmth, odor, discharge, fever, and slow healing – can help you act promptly and avoid serious health risks.
“Detecting ulcers early, even as a callus or blister, is crucial.” – Dr. Andrew Bruyn, DPM [6]
Because diabetic neuropathy often dulls pain signals [3], it’s essential to visually check your feet regularly. Pairing this with proper wound care and managing your blood sugar levels can help reduce the risk of complications. If you notice any of these warning signs, seeking immediate medical care is crucial for effective treatment.
Specialized wound care centers provide options like debridement, advanced dressings, and Hyperbaric Oxygen Therapy (HBOT). Spotting these issues early allows access to treatments that can greatly improve recovery outcomes.
