High cholesterol is commonly referred to as a "silent killer." Unlike other medical conditions, it does not have noticeable symptoms in the early years (or even later) In its early stages, there are no specific symptoms. Many people live for years with dangerously elevated cholesterol levels, unaware of the harm quietly building within their arteries. But though it might not be yelling for help, the body sometimes sends some subtle signals.
That said, cholesterol-related complications can manifest in subtle, silent ways—often misattributed to other causes. Recognizing these early clues may help prevent serious events like heart attacks or strokes.
These are five silent warning signs that may be trying to alert us.
In rare cases, fatty growths may develop over tendons, such as the Achilles or knuckles. These are called tendon xanthomas and are more common in people with familial hypercholesterolemia, a genetic form of very high cholesterol. Though less known, these visible signs are significant and should be evaluated by a healthcare provider.
Small, yellowish bumps or patches on or around your eyelids, xanthelasma, may be a cosmetic blemish, but they can also indicate high cholesterol levels. Composed of cholesterol, these deposits of fat most commonly occur in middle-aged or elderly people. Painless and harmless in and of themselves, they can be an outward manifestation of an underlying lipid disorder that a physician must treat.
Symptoms of dizziness, confusion, or slurred speech can herald a transient ischemic attack (TIA)—also referred to as a mini-stroke. They result when a blood clot rich in cholesterol blocks the flow of blood to the brain temporarily. While the symptoms themselves might take only a few minutes and quickly disappear, they are a medical emergency and an ominous sign of an imminent full-blown stroke. High cholesterol is a major cause of this risk.
