A diagonal crease on the ear, known as “Frank’s sign,” may indicate coronary artery blockage. While not definitive, studies suggest about 70% of those with it have serious arterial issues. Hair loss on the legs can signal peripheral arterial disease (PAD), which restricts blood flow. If you notice this, consult a doctor.
Yellow patches around the eyes, called xanthelasmas, are linked to high cholesterol and an increased risk of heart disease.
A corneal deposit known as arcus senile may suggest dyslipidemia in younger individuals, indicating a blood fat imbalance.
Bluish or purple skin, especially on the lips or fingers, could mean low blood oxygenation, signaling potential heart or lung problems.
If you observe any of these signs, seek medical advice.
