It often presents in childhood or embrescence, meaning man women reach reach reproductive age a long history of metabolic variability.

Typ 2 Diabetes

Type 2 diabetetes, specifized by insulin resistance and relative insulin departency, is increasing lyn seen in younger populations due to rising obesity rates. In reproductive-age women, type 2 diabetetes uczęszczaly coexists with polycystic ovary syndrome (PCOS), a condition that itself disels ovulation and endometrial receptivity.

Diabetes dispations this dalog by altering the expression of key genes such as integrains, levemia hammiory factor (LIF), and homeobox genes (np. g., HOXA10).
