High cholesterol has become one of the most common health concerns in modern life. Because it often develops silently, many people may not realize their cholesterol levels are elevated until it begins to affect their overall health.

When high cholesterol is not detected early, it may increase the risk of serious health problems over time. That is why it is important to understand what cholesterol is, how it affects the body, and which warning signs may sometimes appear.

According to Dr. Laura Purdy, cholesterol is a type of fat-like substance that circulates in the bloodstream. It is produced naturally by the body and can also come from the foods we eat. In some people, genetic factors or other health conditions may cause the body to maintain higher-than-normal cholesterol levels.

Understanding the Different Types of Cholesterol

There are different types of cholesterol, and they are often described as “good” cholesterol and “bad” cholesterol.

HDL, or high-density lipoprotein, is often referred to as the “good” cholesterol. This type helps remove other forms of cholesterol from the bloodstream and supports heart health.

LDL, or low-density lipoprotein, is known as the “bad” cholesterol. High levels of LDL may contribute to the buildup of plaque inside the arteries. Over time, this can narrow the blood vessels and increase the risk of heart disease, heart attack, and stroke.

Understanding the difference between these two types is important for protecting long-term cardiovascular health.

A Possible Hidden Sign on the Skin

Dr. Purdy explains that some people with high cholesterol may develop small cholesterol deposits on the skin. These often appear as soft, yellowish, waxy bumps and are commonly seen around the eyes.

These deposits are known as xanthomas. They can be a visible sign that cholesterol levels may be too high. Although they do not appear in every person with high cholesterol, their presence may be a reason to speak with a doctor and consider a blood test.

Excess Weight and Cholesterol

Dr. Purdy also notes that excess body weight can place additional stress on the body and may increase the risk of several health conditions, including high cholesterol.

People who are overweight or obese may be more likely to have elevated cholesterol levels than those at a healthier weight. This concern does not affect only adults. Children and teenagers with excess body weight may also be at greater risk.

Because of this, routine blood testing may be recommended for adults, adolescents, and children with a high body mass index or excess body weight, especially as part of regular health checkups.

Why Regular Testing Matters

One of the biggest concerns with high cholesterol is that it often causes no obvious symptoms in the early stages. For many people, the only reliable way to know their cholesterol levels is through a blood test.

Regular screening can help detect problems early and allow time for lifestyle changes or medical guidance if needed. A healthy diet, regular physical activity, weight management, and routine medical care all play an important role in supporting healthy cholesterol levels.

Final Thoughts

High cholesterol is often called a silent condition because it may not show clear warning signs right away. However, certain clues, such as yellowish skin deposits around the eyes or the presence of excess body weight, may suggest the need for closer attention.

The best way to protect your health is to stay informed, maintain healthy habits, and speak with a healthcare professional about regular cholesterol screening.
