Heart Disease: 7 warning signs that appear on the skin

Heart disease is the leading cause of death in the world, yet often its symptoms remain dormant for years, and only show up when the condition has worsened to the extent of a heart attack (which can be fatal too) While it is important to get yearly check ups, especially if you have diabetes, High Blood Pressure or are overweight, there are also some signs that your body, especially skin gives you, that go beyond chest pain, and breathlessness. Here are 7 such signs that could signal heart disease, though they are not exclusive to the condition.

One of the most common signs of heart disease that shows on your skin is swelling, especially in your feet, ankles, and lower legs. This swelling happens when your heart is not pumping blood effectively, causing fluid to build up in your tissues. You might notice your shoes feel tighter or see deep marks on your skin after wearing socks. In severe cases, swelling can spread to your upper legs and groin area. If you experience this swelling along with tiredness or shortness of breath, it’s important to see a doctor.

If parts of your skin, such as your fingers or toes, turn blue or purple and don’t return to normal color when you warm up, it could mean your blood is not carrying enough oxygen, and the heart is struggling. This condition, called cyanosis, often signals a blockage in your blood vessels or poor heart function. It’s a serious sign that needs prompt medical attention because lack of oxygen can damage skin and tissues.

Sometimes, yellow or orange waxy bumps or plaques appear on your skin, especially around the corners of your eyes, elbows, knees, or backs of your legs. These bumps are fatty deposits caused by high cholesterol or triglyceride levels in your blood. They are painless but important warning signs that your cholesterol might be dangerously high, increasing your risk of heart disease. If you notice these, get your cholesterol checked and managed.

A web-like or net-like purple or blue pattern on your skin, especially on your legs, may indicate cholesterol embolization syndrome. This happens when small arteries get blocked by cholesterol crystals, causing poor blood flow. This pattern is not a rash or infection and should prompt you to consult a doctor immediately, as it can be linked to serious heart conditions.

Clubbing refers to the rounding and swelling of the tips of your fingers or toes, making your nails look bulbous or curved downward. This change can be a sign of low oxygen levels in your blood, often linked to heart or lung diseases. If you notice your nails changing shape over time, it’s wise to get a medical checkup.

Tiny red or purple lines that look like splinters under your nails can indicate damage to small blood vessels. These lines may be a sign of infective endocarditis, a serious heart infection. They can last for several days and should not be ignored, especially if accompanied by other symptoms like fever or fatigue.
