The word for stomach fat is visceral fat.
Visceral fat is a type of fat that is stored deep within the abdominal cavity, surrounding organs like the liver, stomach, and intestines. It is different from subcutaneous fat, which is the fat that lies just under the skin.
Visceral fat is often referred to as "belly fat" or "abdominal fat."
While some visceral fat is normal and healthy, too much visceral fat can increase your risk of developing serious health problems, such as heart disease, type 2 diabetes, and certain types of cancer.
