Body volume index

Body Volume Index (BVI) is a way to measure how big or small your body is. It's a bit like Body Mass Index (BMI), but instead of just looking at your weight, it also looks at the shape of your body.

Imagine you have two balloons. One is bigger and rounder, while the other is smaller and flatter. Even if both balloons weigh the same, you would be able to tell that the bigger, rounder balloon takes up more space.

BVI works in a similar way. By scanning your body, BVI can tell how much space you take up. This is important because the more space you take up, the more likely you are to have health problems.

But BVI doesn't just look at how big you are. It also looks at your body shape. Imagine two people who weigh the same amount. One person is tall and thin, while the other is short and round. Even though they weigh the same, the shorter person might be at a higher risk for health problems because their weight is more concentrated in one area.

BVI takes all of these factors into account to give you a better idea of your overall health. It's important to remember that BVI is just one tool that doctors use to assess your health. It's always a good idea to talk to your doctor about what your BVI score means for you.
