Which type of diabetes is specifically associated with gestational onset?

Gestational diabetes is specifically defined as diabetes that develops during pregnancy, typically diagnosed in the second or third trimester. This type of diabetes arises when the body cannot produce enough insulin to meet the increased needs during pregnancy, leading to elevated blood glucose levels.

Unlike Type 1 and Type 2 diabetes, which are usually chronic conditions with pathophysiological underpinnings not specifically linked to pregnancy, gestational diabetes is transient and directly related to the hormonal changes that occur in the maternal body during pregnancy.

Maturity-onset diabetes of the young (MODY) is a genetic form of diabetes that occurs due to mutations affecting insulin production but is not associated with pregnancy onset. Gestational diabetes is unique in that it is distinctively characterized by its occurrence only in the context of gestation and usually resolves after childbirth. Therefore, the correct association of gestational onset with diabetes is with gestational diabetes itself.
