Symptoms

Symptoms

Hypercholesterolemia does not cause any symptoms but may eventually lead to heart attack, peripheral artery disease, or stroke due to atherosclerosis.

Familial hypercholesterolemia is associated with:

  • Xanthelasma palpebrarum (yellowish patches underneath the skin around the eyelids)
  • Arcus senilis (white or gray discoloration of the peripheral cornea)
  • Xanthomata (deposition of yellowish cholesterol-rich material) of the tendons – Type III hyperlipidemia may be associated with xanthomata of the palms, knees and elbows.

CausesCauses

  • Cholesterol is a soft, fat-like substance found in the body’s cells and helps form certain hormones and other necessary substances. Too much of cholestreol causes health problmes. Hypercholesterolemia could be caused due to various reasons.
  • Controllable factors which increases risk include:
  • Diet – consumption of foods high in saturated fats
  • Lack of exercise and physical activity
  • Stress and hormones- the physiologic hormone called cortisol, for example, increases LDL cholesterol level
  • Obesity or overweight
  • Smoking
  • Factors that can not be controlled to lower the risk of developing high cholesterol include:
  • Genetics- Genetic contributions are usually due to the additive effects of multiple genes, though occasionally may be due to a single gene defect such as in the case of familial hypercholesterolemia.
  • Side effect of certain medications
  • Other medical conditions such as diabetes and high blood pressure
