Signs and Symptoms

Many people don’t know that they have abnormal blood lipids, including higher levels of LDL or overall cholesterol. That’s because there are usually no signs or symptoms associated with an early buildup of fatty plaques in the arteries.

Plaque is made up of cholesterol and fatty substances. It’s not until there may be a large blockage of the artery that you might notice something is wrong. For example, you may have chest pain, pain in the arms or jaw, nausea, sweating, shortness of breath, or weakness. These usually occur when the blood supply to the heart or brain is being slowed or blocked.

Unfortunately, these blockages can rupture and cause major problems, even when they are much smaller and don't yet cause any early symptoms. That is why, for some people, the first sign of elevated cholesterol may be a heart attack or stroke.

So – even if you’re feeling fine – regular cholesterol and blood lipid checks are important. Your blood lipids are considered in addition to other factors known to make heart disease or stroke more likely such as age, family history, if you have diabetes or high blood pressure, or if you smoke.
