High cholesterol often has no symptoms. Cholesterol is a silent killer, so the damage may be done long before you notice anything is wrong. Some of the signs and symptoms are:
angina from heart disease
xanthomas (fatty skin deposits) on the elbows, buttocks, knees, and tendons
cholesterol deposits around the eyelids, also known as xanthelasmas
cholesterol deposits around the corneas, also known as corneal arcus
Blood tests will reveal that your cholesterol levels—both total and LDL—are higher than normal.
