  • Type I Hyperlipoproteinemia: Type I Hyperlipoproteinemia is a rare inherited condition characterized by high levels of chylomicrons (a type of lipoprotein) in the blood. This condition is the result of low levels of lipoprotein lipase which is responsible for lowering lipoprotein levels. Cholesterol levels are usually normal and the risk of heart disease is low.
  • Type II Hyperlipoproteinemia: Type II Hyperlipoproteinemia is a condition characterized by high levels of beta-lipoproteins in the blood. The high cholesterol results from abnormally high levels of low density lipoproteins in the blood due to a deficiency of LDL receptors. There are two subtypes of this condition: type IIa and type IIb. Lipoproteins are responsible for transporting cholesterol in the bloodstream and high levels of them in the bloodstream means that there are high levels of cholesterol in the bloodstream.
  • Type III Hyperlipoproteinemia: Type III hyperlipoproteinemia is a rare genetic condition characterized by increased blood levels of intermediate density lipoproteins (IDL) which in turn causes high cholesterol levels. The high IDL levels are caused by an abnormality in apolipoprotein E. Apolipoprotein E is a protein found on IDLs which allows the IDLs to bind to liver cells. Without this binding process, the level of IDLs in the blood increase. Lipoproteins are responsible for transporting cholesterol in the bloodstream and high levels of them in the bloodstream means that there are high levels of cholesterol in the bloodstream.
  • Type IIa Hyperlipoproteinemia: Familial Hyperlipoproteinemia is a rare genetic condition characterized by high levels of low density lipoproteins in the blood. A deficiency of LDL receptors leads to an increased level of low density lipoproteins (LDLs) which in turn causes high cholesterol levels. Lipoproteins are responsible for transporting cholesterol in the bloodstream and high levels of them in the bloodstream means that there are high levels of cholesterol in the bloodstream.
  • Type IIb Hyperlipoproteinemia: Type IIb Hyperlipoproteinemia is a condition characterized by increased blood levels of low density lipoproteins (LDL) and apoprotein B (ApoB). This in turn causes high cholesterol levels. Lipoproteins are responsible for transporting cholesterol in the bloodstream and high levels of them in the bloodstream means that there are high levels of cholesterol in the bloodstream.
  • Type IV Hyperlipoproteinemia: Type IV Hyperlipoproteinemia is an inherited condition characterized by high levels of very low density lipoproteins (VLDL) in the blood which in turn causes high cholesterol levels. Lipoproteins are responsible for transporting cholesterol in the bloodstream and high levels of them in the bloodstream means that there are high levels of cholesterol in the bloodstream. The high VLDL levels are a result of increased production and reduced elimination of the VLDLs. Environmental factors are the driving force behind this condition.
  • Type Ia Hyperlipoproteinemia: Type Ia Hyperlipoproteinemia is a rare inherited condition characterized by high levels of chylomicrons (a type of lipoprotein) in the blood. This condition is the result of low levels of lipoprotein lipase which is responsible for lowering lipoprotein levels. Cholesterol levels are usually normal and the risk of heart disease is low.
  • Type Ib Hyperlipoproteinemia: Type Ib Hyperlipoproteinemia is a rare inherited condition characterized by high levels of chylomicrons (a type of lipoprotein) in the blood. This condition is the result of low levels of apolipoprotein C-II which is responsible for lowering lipoprotein levels. Cholesterol levels are usually normal and the risk of heart disease is low.
  • Type Ic Hyperlipoproteinemia: Type Ic Hyperlipoproteinemia is a rare inherited condition characterized by high levels of chylomicrons (a type of lipoprotein) in the blood. This condition is the result of inhibited lipoprotein lipase activity. Lipoprotein lipase is responsible for lowering lipoprotein levels. Cholesterol levels are usually normal and the risk of heart disease is low.
  • Type V Hyperlipoproteinemia: Type V Hyperlipoproteinemia is a rare condition characterized by increased synthesis of very low density lipoproteins (VLDL) and reduced levels of lipoprotein lipase (an enzyme). Lipoproteins are responsible for transporting cholesterol in the bloodstream and high levels of them in the bloodstream means that there are high levels of cholesterol in the bloodstream.

  • Varicose eczema: Varicose eczema is a chronic skin condition that involves the skin on or near varicose veins in the legs - usually the skin on the ankles are affected.
