Signs of high cholesterol
High cholesterol is a common health concern that can increase the risk of heart disease, stroke, and other serious conditions. Often called a “silent” condition, high cholesterol typically does not present any obvious symptoms until it causes complications. This makes it essential to monitor your cholesterol levels regularly. However, certain physical signs and symptoms can indicate underlying high levels. Recognizing these signs early may help prevent more severe health issues.
What is Cholesterol?
Cholesterol is a fatty substance found in the blood. Your body needs it to build healthy cells and produce hormones. There are two types of cholesterol: low-density lipoprotein (LDL) and high-density lipoprotein (HDL). LDL is often referred to as “bad” cholesterol because high levels of it can lead to the build-up of fatty deposits in your arteries, reducing blood flow. HDL, on the other hand, is considered “good” cholesterol as it helps remove excess from your body.
Maintaining a balance between LDL and HDL is crucial for heart health. If LDL levels are too high, it may lead to atherosclerosis, which is the hardening and narrowing of the arteries. This condition can result in heart attacks, strokes, and peripheral artery disease.
1. Xanthomas (Fatty Deposits) on the Skin
One of the most visible signs of high cholesterol is the development of xanthomas. These are yellowish, fatty deposits that can appear under the skin, typically on the elbows, knees, hands, or feet. Xanthomas can range in size and often appear in clusters. While these growths are painless, they indicate high levels of cholesterol in the blood and should prompt a visit to your healthcare provider for further evaluation.
2. Corneal Arcus (Grayish Ring Around the Eyes)
A corneal arcus is another visible sign that may indicate high levels. It appears as a gray or white arc around the cornea, the clear front part of the eye. This ring results from cholesterol deposits and is more common in older adults, but its presence in people under 45 may be an early warning of high levels. Although the ring itself doesn’t impact vision, it serves as a signal that the levels need to be checked.
3. Chest Pain or Angina
Chest pain, also known as angina, is one of the more severe signs of high cholesterol, especially if it’s caused by atherosclerosis. When cholesterol deposits narrow the coronary arteries, the heart receives less oxygen-rich blood, leading to chest pain. Angina often feels like pressure, squeezing, or a burning sensation in the chest and can radiate to the arms, neck, jaw, or back. If you experience chest pain, it’s crucial to seek medical attention, as this could be a warning sign of an impending heart attack.
4. Shortness of Breath
When the levels are high and lead to narrowing or blockage of the arteries, the reduced blood flow can affect not only the heart but also the lungs. Shortness of breath may occur because the heart is not able to pump enough blood to meet the body’s oxygen needs. If you find yourself becoming easily winded during everyday activities, such as walking or climbing stairs, this could indicate underlying heart or vascular issues related to high cholesterol.
5. Numbness or Coldness in Extremities
High cholesterol can also affect the circulation in your limbs. When the arteries that supply blood to your legs, arms, or feet become narrowed, you may experience symptoms like numbness, tingling, or a cold sensation in these areas. Peripheral artery disease (PAD) is a condition that occurs when arteries in the limbs become blocked or narrowed due to cholesterol build-up. PAD can lead to pain while walking, non-healing wounds, or even gangrene in severe cases.
6. Erectile Dysfunction
In men, high cholesterol may contribute to erectile dysfunction (ED). This occurs when the plaque restricts blood flow to the penis, making it difficult to achieve or maintain an erection. ED can be one of the early signs of cardiovascular disease, and addressing high cholesterol may improve this condition and reduce the risk of heart problems.
7. High Blood Pressure
High cholesterol can lead to high blood pressure (hypertension). As cholesterol deposits accumulate in the arteries, they become less flexible, forcing the heart to pump blood harder through the narrowed pathways. This increased workload elevates blood pressure, further straining the cardiovascular system. If left untreated, high blood pressure can damage the heart, kidneys, and other organs.
Prevention and Management of High Cholesterol
Preventing high cholesterol is possible through lifestyle changes, including:
- Diet: Incorporate more fruits, vegetables, whole grains, and lean proteins into your meals. Avoid trans fats, and limit saturated fats.
- Exercise: Regular physical activity helps raise HDL (good cholesterol) and lower LDL (bad cholesterol).
- Weight Management: Maintaining a healthy weight reduces the risk of high levels.
- Regular Checkups: Routine blood tests can detect high levels early, enabling you to take action before complications arise.
In Summary
While high cholesterol often remains unnoticed, certain physical signs like xanthomas, chest pain, and corneal arcus may indicate elevated levels. Recognizing these symptoms and seeking medical attention can help prevent life-threatening conditions like heart disease and stroke. Through diet, exercise, and regular medical check-ups, you can manage your fat levels and protect your cardiovascular health.
