Diabetes and heart disease can both affect your feet, but they do so in different ways. Understanding the connection can help prevent serious complications.
How diabetes affects your feet
- Nerve damage (diabetic neuropathy): High blood sugar over time can damage nerves, causing numbness, tingling, burning, or loss of feeling. A person may not notice a blister, cut, or infection.
- Poor circulation: Diabetes can narrow or damage blood vessels, slowing healing and increasing the risk of infections.
- Higher infection risk: Even small wounds can become serious if blood flow and immune function are impaired.
- Foot ulcers: Untreated sores can develop into deeper wounds and, in severe cases, may lead to amputation.
How heart disease affects your feet
- Reduced blood flow: Atherosclerosis (plaque buildup in arteries) can limit circulation to the legs and feet, causing:
- Cold feet
- Pale or bluish skin
- Leg pain when walking that improves with rest
- Slow-healing wounds
- Peripheral artery disease (PAD): This is a common circulation problem linked with heart disease and can increase the risk of foot problems.
Foot care tips (especially if you have diabetes or heart disease)
- Check your feet daily for cuts, cracks, blisters, swelling, or color changes.
- Keep feet clean and moisturized (but avoid putting lotion between toes).
- Wear well-fitting shoes and clean socks.
- Avoid walking barefoot, especially outdoors.
- Have regular foot checks with a healthcare professional if you have diabetes or circulation problems.
Seek medical care promptly for a foot wound that won’t heal, spreading redness, warmth, swelling, drainage, blackened skin, or sudden loss of sensation.
If you have diabetes or heart disease, I can also provide a simple daily foot-check routine.
