Myo-inositol May Prevent Gestational Diabetes

Dangerously high blood sugar during pregnancy can be prevented by a simple and safe food supplement according to several studies.

 

Raised blood sugar levels in pregnancy, clinically known as Gestational Diabetes Mellitus (GDM) is one of the most common pregnancy complications, affecting approximately 35,000 pregnant women in the UK each year (1). The prevalence of GDM is on the rise, due to modern-day sedentary lifestyles and poor dietary habits increasing the risk of such metabolic disorders.

 

GDM may increase the risk of pregnancy complications, excessive birth weight, and the baby’s likelihood to develop diabetes in later life. A review of recent evidence indicates that myo-inositol, a naturally-occurring vitamin-like substance, may potentially prevent GDM (2).

 

After combining results from four trials involving a total of 586 participants, X Guo et. al advocated myo-inositol supplementation in preventing the onset of GDM (2). The study participants were given a combination of 4g myo-inositol and 400mg folic acid per day during pregnancy, until delivery.
Compared to placebo, myo-inositol supplementation significantly reduced the risk of GDM in pregnant mothers, as results displayed improved markers of insulin sensitivity and lowered blood glucose levels.


Myo-inositol, an isomer of inositol that occurs naturally within the body, is also found in dietary sources such as fruits, vegetables, nuts and cereals and is often considered to be part of the vitamin B-complex. While the direct mechanism of action is unclear, it is suggested that myo-inositol enhances insulin action. This link may explain the benefits of myo-inositol supplementation in preventing insulin-related metabolic disorders, such as GDM.


Although the evidence is promising, further research is required to test these effects on diverse populations, and understand the underlying mechanisms involved. Nonetheless, myo-inositol can be safely administered during pregnancy to help prevent against metabolic disorders, including gestational diabetes.
