The symptoms of mixed hyperlipoproteinemia include high levels of cholesterol, triglycerides, xanthoma and whitish edges of the cornea, according to RightDiagnosis.com. The disease shows no physical symptoms in some individuals, which puts them into a high risk of heart disease.
Hyperlipoproteinemia describes a condition of high levels of lipoproteins in the body, the compounds responsible for transporting cholesterol. The condition leads to increased levels of cholesterol in the bloodstream, explains RightDiagnosis.com. The low-density lipoprotein cholesterol, or LDL cholesterol, causes a hard deposit that clogs the arteries.
Mixed hyperlipoproteinemia causes xanthoma, a condition that manifests through fatty skin growths, especially on the buttocks, feet and hands, notes Healthline. Xanthoma deposits vary in size, sometimes appearing as yellowish flat bumps under the skin. The increased levels of cholesterol and triglycerides increase the risk of heart attacks and heart diseases. Individuals with mixed hyperlipoproteinemia also have higher rates of becoming obese or developing glucose intolerance.
Severe cases of familial hyperlipoproteinemia lead to the formation of a white or gray arc around the cornea, says Mayo Clinic. The condition is uncommon, as the average person with a high cholesterol level does not develop the circumferential arc. The arcs do not cause discomfort or hinder the normal functioning of the eyes. Treatment of the condition involves controlling cholesterol and triglyceride levels.
