Gestational Diabetes Mellitus

According to the figures in 2016, it is estimated that at least 20% of pregnant women in Hong Kong have GDM, significantly higher than the 12% recorded 25 years ago1.

What is Gestational Diabetes Mellitus?

Pregnant women usually have a slightly higher blood glucose level for development of the fetus.  However, hormonal changes in pregnant women may also lead to insulin resistance resulting in a higher glucose level, a condition known as Gestational Diabetes Mellitus(GDM).  GDM could be diagnosed by OGTT.  According to international definition, a pregnant woman is diagnosed with GDM if her fasting plasma glucose level ≥ 5.1 mmol/L, 1-hour plasma glucose level ≥ 10.0 mmol/L, or 2-hour plasma glucose level ≥ 8.5 mmol/L1.

If a pregnant woman with gestational diabetes does not receive proper treatment, both she and her foetus can be seriously affected. (e.g. the baby being large for its gestational age, premature birth etc.), so follow dietitian and doctor advice on dietary control.

GDM Risk Factor

If a pregnant woman has the following risk factors, her chance of having gestational diabetes is higher.

  • Over 35 years history of polycystic ovary syndrome
  • History of gestational diabetes
  • Had delivered a baby with birth weight over 4 kg
  • Family history of diabetes in first degree relatives
  • Overweight (BMI > 25)
    BMI = Weight (kg) ÷ (Height (m) × Height (m) )

If a pregnant woman with GDM does not receive proper treatment, both she and her foetus can be seriously affected (e.g. the baby being large for its gestational age, premature birth etc.). So, it is important to follow dietitian and doctor advice on dietary control.

Continuous Glucose Monitoring (CGM)

Continuous Glucose Monitoring (CGM) :Zero Finger Sticks.  A breakthrough technology in diabetes management Women with Type 1 or Type 2 in pregnancy or those with gestational diabetes usually require six or more fingersticks per day. CGM is a diabetes management tool that measures glucose levels 24 hours a day using a sensor inserted just under the skin. No finger sticks are required.
