Glucose Management during Pregnancy


Gestational diabetes mellitus (GDM) is characterized by glucose intolerance during pregnancy.

Pregnancy may increase urinary chromium loss, making pregnant women susceptible to chromium deficiency (Morris et al., 1995). Sundararaman et al (2012) found out that serum chromium level of women with gestational diabetes are lower than in controls.


Chromium is an essential mineral which aids in lipid and glucose metabolism. It is a key substance for the formation of Glucose Tolerance Factor (GTF) complex. Therefore, chromium helps to improves glycemic control.

According to study done by Jovanovic et al (1999), gestational diabetes women need about 4-8mcg/kg of chromium daily. Supplementation of chromium for 8 weeks in GDM women significantly lower the HbA1c level compared to control group, with reading of 5.2% vs 5.6%, respectively.
