Why Diabetics and People with Vascular Issues Are at Higher Risk for Ulcers and Wounds

Understanding the Connection

1. Poor Circulation

Both diabetes and vascular conditions—such as peripheral artery disease (PAD)—affect blood flow, particularly to the extremities like the feet and legs. When blood circulation is compromised, the body struggles to deliver enough oxygen and nutrients to support proper wound healing. This slow response can turn a minor injury into a lingering wound or ulcer.

2. Nerve Damage (Neuropathy)

Diabetic neuropathy is a condition that damages the nerves, especially in the feet. When sensation is reduced or lost, individuals may not notice a blister, cut, or pressure injury until it has become infected or severely ulcerated. Without early detection, these wounds can grow worse before treatment begins.

3. Weakened Immune Response

High blood sugar levels in diabetics impair the immune system, making it harder to fight off bacteria and other pathogens. This increases the risk of infections, which can rapidly worsen an ulcer or wound and may even lead to serious complications like cellulitis or sepsis.

4. Skin Changes and Dryness

Diabetes and vascular issues can cause the skin to become dry, cracked, or thin. These conditions make the skin more vulnerable to injuries and less capable of forming the strong protective barrier needed to keep bacteria out.

Common Types of Wounds in At-Risk Individuals

Diabetic Foot Ulcers: Often located on the bottom of the feet, these ulcers can become deep and infected, sometimes leading to amputation if not treated properly.
Venous Stasis Ulcers: Common in people with chronic venous insufficiency, these are typically found around the ankles and are slow to heal.
Pressure Ulcers (Bedsores): People with limited mobility and poor circulation are more prone to developing these ulcers, especially on heels, hips, and lower back.

Prevention and Care Strategies

While the risks are real, many ulcers and wounds can be prevented with diligent care and monitoring:

Daily Foot Checks: Inspect feet and lower legs daily for cuts, blisters, or signs of infection.
Manage Blood Sugar and Blood Pressure: Keeping diabetes and vascular conditions under control is crucial for preventing complications.
Wear Proper Footwear: Shoes should be comfortable, supportive, and not too tight to prevent pressure points and blisters.
Moisturize Regularly: Prevent dry, cracked skin, especially around the feet and ankles.
