It is due to the insufficiency of secretion of a pancreatic hormone, called insulin, which allows blood glucose to enter the cells and provide them with the necessary energy.
When there is no insulin, the sugar accumulates in the blood, or even passes into the urine.
It is an inherited disease, often revealed during a urine test where the presence of sugar is found.
Diabetes requires a daily, lifetime injection of insulin, combined with a balanced diet.
