Loss of weight that occurs suddenly and unintentionally
Another clear and early indicator of diabetes is a sudden and unexpected reduction in body weight of between 5 to 10 kilograms (about 11 to 22 pounds) in a matter of weeks to a few months. If you have type 1 diabetes, you are more likely to have weight loss than the general population. The reason for this is that persons who have type 1 diabetes can have a rapid shutdown of their sugar metabolism.
The following are the reasons for this: As a result of low glucose (energy) levels in the blood, the body believes that it is starving and reacts by metabolizing muscle proteins in order to supply a fresh source of energy to the cells. This happens because glucose is the body’s primary source of energy. This results in the breakdown of muscular tissue, which in turn causes unintended and rapid weight loss.
