Visceral adipose tissue is the fat stored around internal organs. Its increase has been linked as a risk factor for cardiovascular diseases, such as heart attack and atherosclerosis, and metabolic diseases.
Prediction of visceral adipose tissue
Adipose tissue or fat tissue is made up of cells capable of accumulating fat, the adipocytes. This tissue has various functions such as metabolic, cushioning, protecting and holding in place internal organs and other structures of the body.
In the human body, adipose tissue is located under the skin (subcutaneous fat), around the organs (visceral fat), in the bone marrow (yellow bone marrow) and in the breasts. Specifically, visceral fat functions as a lipid reserve and provides protection. In general, men tend to have a higher rate of visceral fat due to male hormones, while women accumulate subcutaneous fat in the buttocks, hips and limbs due to oestrogen. After menopause, women start to accumulate more fat in the abdomen.
Visceral fat is located in the abdominal cavity and its excess has been directly related to an increased risk of type 2 diabetes, insulin resistance, inflammatory diseases and other obesity-related diseases. Why abdominal fat is more harmful than other fat deposits, such as subcutaneous adipose tissue, has not been fully elucidated. Possible hypotheses point to a greater lipolytic capacity and its resistance to the antilipolytic effects of insulin, resulting in higher concentrations of circulating fatty acids. In addition, studies also point to visceral fat having a higher rate of macrophage infiltration, resulting in a proinflammatory profile that promotes insulin resistance.
