Gestational diabetes symptoms

Gestational diabetes is a particular kind of diabetes only affecting women during pregnancy.

It often does not cause any symptoms, and the condition may be diagnosed through routine antenatal screening tests.

Pregnancy hormone changes make the body more resistant to insulin, allowing blood glucose (blood sugar) levels to rise. This is called hyperglycaemia. When this happens, the symptoms may include:

  • Thirst, dry mouth
  • Urinating more often
  • Tiredness
  • More infections, including thrush
  • Vision changes

Sometimes it can be hard to tell changes due to pregnancy from symptoms of gestational diabetes. For example, you may feel more tired and visit the toilet more often as a normal part of being pregnant.

However, if you have any of these symptoms, talk to your GP or midwife. Based on these symptoms, and other risk factors, they may recommend tests for gestational diabetes in addition to your usual antenatal tests schedule.
