5 silent symptoms of high cholesterol that may go unnoticed

High cholesterol is commonly referred to as a "silent killer." Unlike other medical conditions, it does not have noticeable symptoms in the early years. 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.

Visible lumps on tendons (Tendon Xanthomas)

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.

Leg pain while walking (Claudication)

If you experience odd pain or cramping in your legs when walking or climbing stairs, it could be more than tired muscles.

This symptom, known as claudication, is commonly associated with peripheral artery disease (PAD)—a condition in which cholesterol deposits narrow the arteries supplying the limbs with blood. It usually decreases with rest but returns with activity. PAD is a red alert for extensive arterial damage due to high cholesterol.

Yellow deposits on eyelids (Xanthelasma)

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.

Numbness or tingling in limbs

Decreased circulation because of constricted blood vessels may cause tingling or numbness in your arms or legs. While most individuals equate this sensation as being related to nerves or posture, it may also be a manifestation of cholesterol narrowing arteries and shutting off regular blood flow.

Persistent such symptoms, particularly without any apparent reason, may be an indication of early nerve damage caused by poor circulation.

Sudden dizziness or slurred speech

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.

Get tested today!

Since high cholesterol is unlikely to present itself until the damage is well established, the best prevention is frequent screening by lipid profile test. If you develop any of the symptoms listed above, particularly if you are at risk due to obesity, diet, smoking, or family history, see a health care provider immediately. Lifestyle changes, dietary alterations, and early treatment can be very effective at shielding your heart and your health.
