4. Era arc
Arcus senilis is a deposit that forms at the edge of the cornea and is common in older people. However, in younger people, its presence may indicate severe dyslipidemia, or fluctuations in blood fats.
Pay attention to this sign and consult a specialist if you notice this curvature before old age.
5. Cyanide formation in the skin
Cyanosis occurs when the skin takes on a bluish or purplish hue due to poor oxygenation of the blood. It can affect the lips, fingers, or skin in general. It can be a sign of a heart or lung problem.
Don’t ignore this sign and see your doctor. Different forms of cyanosis, whether central or peripheral, indicate problems with the lungs or heart.
