Abstract:
HIV lipodystrophy is characterized by peripheral, subcutaneous lipoatrophy in the face, arms, legs, and buttocks and central fat accumulation in the neck, breasts, and abdomen (referred as lipohypertrophy). Lipodystrophy is associated with atherogenic lipid abnormalities, low levels of HDL cholesterol, insulin resistance, and, less commonly, hyperglycaemia. Causes of lipodystrophy are not completely elucidated. The prevalence of lipodystrophy ranges from 20% to 70% of the patients after one year of ART, depending on the type of ART, with lower prevalence in more recent studies of newer agents. Treatment strategies are disappointing. A multidisciplinary approach is now proposed in the Geneva University Hospital in order to coordinate efforts from different department, including internal medicine, infectiology or esthetic surgery for example.

Lipolysis: The Breakdown of Lipids:
Lipolysis is the process of breaking down lipids, particularly triglycerides, into glycerol and fatty acids. This process typically occurs in the adipose tissue and is triggered by various hormones, including glucagon and...
Lipid Absorption
These breakdown products bind with bile salts and lecithin to form micelles, which quickly pass between microvilli to come in close contact with the apical...
