Diet and Exercise May Help Prevent Gestational Diabetes
Gestational diabetes, or gestational diabetes mellitus (GDM), is characterized by elevated blood glucose levels detected for the first time during pregnancy. This condition can pose risks to both the mother and the developing baby.
During pregnancy, a woman’s body undergoes changes in nutrient processing to support the baby’s growth. Insulin sensitivity typically increases in the first trimester but decreases in the second and third trimesters.Women who develop gestational diabetes experience a reduced initial increase in insulin sensitivity, followed by a greater-then-normal decrease later in pregnancy, leading to high blood sugar. Elevated fat levels in the mother’s blood may also contribute to the baby growing larger than average.
Women with gestational diabetes face a higher likelihood of pregnancy complications, including high blood pressure and induced labor. They also have an increased long-term risk of developing type 2 diabetes. Babies born to mothers with GDM are more prone to birth injuries due to their larger size and may experience breathing difficulties,jaundice,and low blood sugar shortly after birth,as well as obesity and diabetes later in life.
A review of 71 randomized controlled trials, encompassing 23,154 pregnant women, examined various interventions to prevent gestational diabetes. These interventions included dietary adjustments, exercise regimens, dietary supplements, medications, and management of pre-existing health conditions. The quality of evidence varied from very low to high.
Combining diet and exercise showed promise in reducing the risk of gestational diabetes compared to standard care, according to findings from 19 trials involving 6,633 women.
However, the impact of dietary advice alone, a low glycemic index diet versus a moderate-to-high glycemic index diet, and exercise alone on GDM risk remained unclear.
Research indicates that omega-3 fatty acid supplementation during pregnancy had no discernible effect on gestational diabetes risk, based on 12 trials involving 5,235 women.
Supplementation with myo-inositol during pregnancy possibly reduced the risk of GDM,according to three trials with 502 women. Similarly, vitamin D supplementation during pregnancy showed a potential benefit in reducing GDM risk, as indicated by four trials with 446 women, all conducted in Asian countries where the women’s pre-supplementation vitamin D levels were largely unknown.
The effect of vitamin D given with calcium, or with calcium plus other minerals, and probiotics with dietary intervention on GDM risk was unclear.
The drug metformin showed a possible benefit in reducing the risk of developing gestational diabetes when given to obese pregnant women,according to three trials involving 892 women.
Evidence from eight small trials showed unclear effect on GDM risk for heparin, aspirin, leukocyte immunisation or immunoglobulin (IgG) given to women who had previously experienced a stillbirth.
Universal screening for thyroid problems, compared to risk-based screening, had no effect on gestational diabetes risk, according to one trial involving 4,516 women. two different approaches to managing the mothers’ asthma also had an unclear effect.
What’s next
While a combination of exercise and diet, along with myo-inositol and vitamin D supplementation, may offer benefits in reducing gestational diabetes risk, further high-quality research is needed to confirm these findings and explore the use of metformin. notably, no trials have assessed interventions implemented before pregnancy.
