Visceral fat area, also known as visceral adipose tissue (VAT), refers to the amount or area of fat that is stored in the abdominal cavity, particularly around and between internal organs such as the heart, liver, stomach, and intestines. Unlike subcutaneous fat, which is the fat located just beneath the skin, visceral fat is found deep within the abdominal area, surrounding the vital organs.

The measurement of visceral fat area is typically performed using imaging techniques like computed tomography (CT scans) or magnetic resonance imaging (MRI). These methods provide information about the specific location, area, and volume of visceral fat. Accumulation of visceral fat in the abdominal region is associated with various health risks, including heart disease, type 2 diabetes, hypertension, and other chronic diseases.

High levels of visceral fat are considered detrimental to health because this type of fat can release bioactive substances, such as inflammatory cytokines, which may lead to inflammation and metabolic issues. Therefore, measuring visceral fat area can be used to assess an individual's risk of developing chronic diseases.

Maintaining a healthy lifestyle, including a balanced diet and regular physical activity, can help reduce the accumulation of visceral fat. Weight management, increased physical activity, and dietary control are all strategies that can contribute to reducing visceral fat and promoting overall health.
