I learnt that total blood sugar in human body is just 5 grams ie one teaspoon of sugar. Just 1/8 of Coca-Cola can.

The Liver is most precision organ which maintains it within find range of 4 grams to 6 grams in blood quantity of half bucket ie 7 litres.

Imagine a half bucket of water with one teaspoon of sugar. If it teaspoon becomes table spoon then it is called Diabetes.
