It"s a form of diabetes that develops during pregnancy, usually during the 2nd or 3rd trimester (hence why we call it gestational). It tends to disappear after the birth of the baby. Macrosomia (fetal) previous baby was large example: >9 lbs. A history (previous gestational diabetes diagnosis or family history of diabetes mellitus) However, all types are due to some issue with insulin. Type 1 diabetes: this is autoimmune and occurs because the cells that produce insulin (beta cells in the pancrea) are destroyed and produce little to no insulin. Therefore, there is no insulin to influence the cells to take in glucose, so it hangs out in the blood (hyperglycemia) and can leak into the urine. Type 2 diabetes: it"s an insulin resistance issue meaning the cells are not receptive to insulin"s influence. Therefore, insulin can"t influence cells to take in glucose, which will hang out in the blood (hyperglycemia) and can leak into the urine.
