Symptoms of high cholesterol may appear in the feet; know what it is

Hypercholesterolemia is known to progress silently. For years, it can build up in the body without causing obvious symptoms, making it difficult to identify the problem early. Still, the body finds subtle ways to signal that something is not right — and one of those warnings may show up in the feet.

Recent research is calling attention to changes in the Achilles tendon as a possible indication of high cholesterol. This discovery helps broaden the view of symptoms that, at first glance, seem disconnected from heart health.

What is the relationship between the Achilles tendon and cholesterol?

A study published in the scientific journal Lipids in health and disease identified an association between high blood cholesterol and thickening or inflammation of the Achilles tendon. This condition is called tendon xanthoma and occurs when there is a buildup of fat in the tendons.

According to researchers, these deposits can appear as small nodules or simply as an increase in the thickness of the tendon, often without pain. The Achilles tendon is usually the most affected area, and in many cases this change is the first visible clinical sign of high cholesterol.

According to research, the presence of xanthomas generally reflects elevated cholesterol levels throughout the body, functioning as an important marker for the study and monitoring of cardiovascular risk.

Other subtle signs that deserve attention

In addition to the feet, high cholesterol can manifest itself in less obvious and easily overlooked ways. In an interview with the site Health Shotsthe cardiologist Swarup Swaraj highlighted some of these signs:

• Yellow spots on the skin: Small yellowish spots or bumps, especially on the eyelids, knuckles, or between the fingers, may indicate fatty deposits under the skin. Although they do not pose an immediate danger, they serve as a warning to check blood cholesterol levels;
• Persistent fatigue: A constant feeling of fatigue, even after sleeping well, may be linked to impaired blood circulation. A study published in the Journal of Psychosomatic Research linked reduced blood flow and clogged arteries to frequent feelings of exhaustion;
• Chest discomfort: Pain, tightness, or pressure in the chest during mild exertion—such as climbing stairs or walking faster—may characterize angina. This symptom occurs when the heart is receiving less oxygen due to narrowing of the arteries and should be investigated urgently.

Why is high cholesterol so dangerous?

When there is an excess of LDL (“bad”) cholesterol and an imbalance in relation to HDL (“good”), the risk of complications increases considerably. Some of the main associated problems include:

• Atherosclerosis: formation of fatty plaques in the arteries, which hinder blood circulation;
• Cardiovascular diseases: such as angina, coronary heart disease and heart attack;
• Hypertension: narrowing of the arteries can increase blood pressure;
• Stroke: plaques in the cerebral arteries increase the risk of stroke;
• Peripheral arterial disease: reduced flow in the legs, causing pain when walking and other complications.

When to investigate?

Experts emphasize that early identification of these signs can prevent more serious consequences, such as a heart attack or stroke. People with a family history of heart disease, high cholesterol, or persistent symptoms should see a doctor and have laboratory tests to check their lipid profile. Even a silent high cholesterol level leaves clues. Learning to recognize them is an important step toward protecting your heart and your overall health.
