Living with type 1 diabetes brings its own set of health challenges, one of which is the risk of getting diabetic foot ulcers. These ulcers can lead to serious complications if not managed properly. In this blog, we'll explore what diabetic foot ulcers are, how they form, their symptoms, risk factors, ways to prevent them, and treatment options.
What are diabetic foot ulcers?
Diabetic foot ulcers are open sores or wounds that can develop on the feet of someone with diabetes. They typically develop due to a combination of factors, including nerve damage (neuropathy), poor circulation, and increased pressure on certain areas of the foot. These ulcers can range from small cuts to serious infections, so getting them checked out as soon as possible is important to prevent them from worsening.

How do they develop?
Nerve damage (neuropathy): High blood sugar can damage the nerves in your feet, making it challenging to feel injuries or pressure.
Poor circulation: Diabetes can reduce blood flow to your feet, making it harder for wounds to heal and increasing the risk of infection.
Foot deformities: Conditions like bunions or hammertoes can create uneven pressure on the foot, increasing the chances of ulcers forming.
Infections: Small cuts or blisters can get infected, especially for people with poor circulation or neuropathy.
Symptoms of diabetic foot ulcers
The symptoms of diabetic foot ulcers can vary, but common signs include:
- Red, swollen, or tender areas on the foot
- Open sores or wounds that may drain pus
- Dark or black tissue around the ulcer
- Pain
- Changes in skin color or temperature
It’s essential to check your feet regularly for any changes, especially if you can't feel them, to avoid an ulcer.
Tips for preventing diabetic ulcers
Daily foot inspections - Make it a habit to inspect your feet daily. Look for any cuts, blisters, redness, or swelling. Use a mirror if necessary to check the bottoms of your feet.
Maintain blood sugar levels - Keeping your blood glucose levels within target ranges is vital for preventing complications, including foot ulcers. Work with your healthcare team to create a management plan.
Wear proper footwear - Choose well-fitting shoes that provide support and protection. Avoid walking barefoot, even at home, to prevent injuries.
Foot hygiene - Wash your feet daily with mild soap and water, and dry them thoroughly, especially between the toes. Moisturize the skin but avoid applying lotion between the toes to prevent fungal infections.
Manage calluses and corns - Regularly trim calluses and corns to prevent pressure points. A podiatrist can help with proper trimming techniques.
Stay active - Regular physical activity promotes good circulation, which benefits foot health. Consult with your healthcare provider to find suitable exercises.
Treatment Options
If you get a diabetic foot ulcer, it's really important to get it treated early. Treatment options might include:
- Wound Care: Cleaning the ulcer and using the right dressings to help it heal.
- Antibiotics: If there’s an infection, your doctor might prescribe antibiotics.
- Debridement: This means your healthcare provider may need to remove dead or infected tissue from the ulcer to help it heal.
- Pressure Relief: Wearing special footwear or using devices to take pressure off the ulcer.
- Surgery: In serious cases, surgery might be needed to remove infected tissue or increase blood flow.
Diabetic foot ulcers can be a serious issue for people with type 1 diabetes, but with careful management, they can often be prevented or treated effectively. Staying on top of your foot health, maintaining stable blood sugar levels, and getting regular check-ups, can help protect your feet and overall well-being.
