[Lipid metabolic disorders in obesity: their epidemiology, physiopathology and clinico-therapeutic implications].
The centralization of body fat, particularly in abdominal or visceral depots, is associated with qualitative and quantitative lipid abnormalities. Examples of these qualitative alterations include changes in low density lipoprotein composition, namely an increased number of small or dense low density lipoprotein particles, which seem to be prone to increased lipid oxidation. Oxidative modification of low density lipoproteins is involved in atherosclerotic development of the arterial wall. Alterations of lipid composition often arise in a context of insulin resistance with hyperinsulinism. Genetic features, such as apolipoprotein E polymorphism, also play a significant role in lipoprotein metabolism. The principle treatment of obesity and associated dyslipidemia is to reduce energy intake through diet. Moderate exercise is effective, especially in patients with insulin resistance. Drug therapy is considered primarily for patients who refuse to make behavioral changes.
