The Link Between Diabetes and Foot Ulcers: Prevention and Treatment Options

Diabetes is a growing health concern that affects millions worldwide. While managing blood sugar levels is the primary focus of treatment, diabetes can lead to several complications if not well controlled. One such complication is diabetic foot ulcers, a condition that often goes unnoticed until it becomes severe. Understanding the link between diabetes and foot ulcers, along with how to prevent and treat this issue, is crucial for every diabetic patient.
Dr. Preethi Mrinalini, a renowned consultant surgeon at Marinas Clinic and Apollo Hospitals, emphasizes the importance of early detection and proper management of diabetic foot ulcers. With years of experience as one of the best female surgeons in Chennai, she sheds light on how individuals with diabetes can protect their feet from ulcers and other related complications.
How Does Diabetes Cause Foot Ulcers?
Diabetes affects the body in several ways, but its impact on circulation and nerve function is directly linked to foot ulcers. High blood sugar levels can damage blood vessels, leading to poor circulation, particularly in the lower extremities. This reduced blood flow makes it harder for the body to heal minor injuries such as cuts, blisters, or sores. Additionally, diabetes can cause nerve damage, a condition known as diabetic neuropathy, which dulls the sensation in the feet.
People with diabetic neuropathy might not feel pain when they injure their foot, allowing minor issues to worsen over time. A small blister, when left untreated, can become infected and develop into a serious ulcer.
Risk Factors for Diabetic Foot Ulcers
Some diabetic patients are more prone to foot ulcers than others. The following risk factors can increase the likelihood of developing foot ulcers:

  • Poorly managed blood sugar: Uncontrolled diabetes can lead to faster nerve damage and circulation issues, making it harder for the body to heal injuries.
  • Peripheral artery disease (PAD): PAD reduces blood flow to the extremities, further increasing the risk of foot ulcers.
  • Foot deformities: Conditions such as bunions, hammertoes, and flat feet can cause pressure points that lead to ulcers.
  • Improper footwear: Wearing shoes that are too tight or uncomfortable can cause blisters or sores, which can develop into ulcers.
  • Smoking: Smoking constricts blood vessels and reduces circulation, which can slow down the healing process.
  • History of foot ulcers: If you’ve had a foot ulcer in the past, you are more likely to develop another.

Prevention of Diabetic Foot Ulcers
Preventing foot ulcers requires a proactive approach. Diabetic patients should take extra care of their feet and adopt preventive measures, including:

  • Regular Foot Inspections: Examine your feet daily for any cuts, blisters, redness, or swelling. Using a mirror can help you see areas that are difficult to reach.
  • Proper Footwear: Always wear well-fitting shoes that provide support and cushioning. Special diabetic shoes are available to reduce pressure points on the feet.
  • Keep Feet Clean and Moisturized: Clean your feet daily with lukewarm water, dry them thoroughly, and apply moisturizer to prevent dry skin, which can crack and lead to infections.
  • Regular Medical Checkups: Regular visits to your healthcare provider for foot exams can help detect any issues early. Your doctor may recommend seeing a podiatrist for specialized foot care.
  • Control Blood Sugar Levels: Managing your diabetes effectively is the most critical preventive measure. Keeping your blood sugar within the target range can help reduce nerve and blood vessel damage.

Treatment Options for Diabetic Foot Ulcers
If a foot ulcer develops, early intervention is essential to prevent complications such as infection or the need for amputation. Treatment options vary based on the severity of the ulcer:

  • Wound Care: Proper cleaning and dressing of the wound are crucial. Your healthcare provider may remove dead tissue (debridement) to promote healing.
  • Offloading: Reducing pressure on the affected foot is important for recovery. This can be done with specialized footwear, crutches, or a wheelchair in severe cases.
  • Medications: Antibiotics may be prescribed if the ulcer is infected. In some cases, your doctor may recommend medications that promote healing by improving circulation.
  • Surgical Intervention: For ulcers that do not respond to conservative treatment, surgery may be required. Surgical options include correcting foot deformities or improving blood flow through vascular surgery.
  • Advanced Therapies: Hyperbaric oxygen therapy and growth factor treatments are some of the advanced therapies available for stubborn foot ulcers.

When to See a Doctor
It’s essential for diabetic patients to seek medical attention as soon as they notice any signs of foot ulcers. Delaying treatment can lead to infections, which may result in severe complications, including amputation.
