How big is our stomach?
ANot as big as most people think! Although the size of our stomach can vary in size by a few centimetres from person to person, just as the length of our fingers or circumference of our head does, the average stomach is around 13cm wide, 15cm thick and 10cm high – so about the size of a large mug. So, how do some people manage to fit in a whole pizza? Well, we can stretch our stomach, like we blow up a balloon, but we don’t have to. Stretching our stomach by just a few centimetres is enough to make us feel full, as long as we allow time for the fullness
message to reach our brain.
