Where it strikes

Medical treatment

  • Diet and monitoring first
  • metformin
  • insulin if targets are missed
  • growth scans
  • glucose test 6–13 weeks after birth

Natural & lifestyle

  • Low-glycaemic diet
  • walking after meals
  • weight management before the next pregnancy
  • breastfeeding lowers later risk

Emerging & experimental

  • Continuous glucose monitoring in pregnancy
  • early screening in high-risk women

Alternative, off-label & anecdotal

Approaches used outside the guidelines, with what their supporters report and what testing has found so far.

  • Myo-inositol — trials lowered the rate of gestational diabetes in women at risk mixed evidence
  • Probiotics — trials found no prevention not confirmed in trials
  • Vitamin D — small studies early / small studies
