Glucose is the main source of energy for our bodies, non can live without it.

Gestational diabetes fasting glucose level is a golden point to treat gestational DM.

Although, if glucose levels increased above normal during pregnancy this will harm on the mother and her baby.

So, it’s important to keep the normal fasting blood sugar in pregnancy

So, we will discuss some notes about gestational diabetes fasting glucose, and what can increase its level?

Gestational diabetes fasting glucose, why the high level?

Did you eat something earlier in the evening?

Well, if you eat too many carbs in the evening meal or snacks before sleeping, this can cause high blood glucose fasting level in the early morning.

As a result, your body releases insulin and spend the whole night in decreasing glucose level in the blood.

And don’t forget that your gastrointestinal tract activity is depressed during the night which will slow down glucose absorption into the bloodstream.

All of these may contribute to the high fasting glucose level.

Hydration levels and its effect on gestational diabetes fasting glucose

Dehydration can cause a high blood sugar level as water helps in flushing excess sugar from the blood.

So, it’s important to drink a lot of water, especially before bedtime.

Dawn phenomenon

Your body consumes glucose for its energy and it’s important to have extra energy supply of glucose to be able to wake up.

So, in early morning hours (hence the dawn) usually between 3 am and 8 am your body starts to release diabetogenic hormones (cortisol, glucagon, and growth hormone) that cause blood sugar levels to rise.

This occurs in all people either diabetic or not, but in diabetics, there is not enough insulin to process this sugar rush in the blood

So, high gestational DM fasting glucose level occurs in the morning.

Somogyi effect (rebound hyperglycemia)

If your blood sugar drops too low in the night while you are sleeping, the body responds by increasing glucose release by the liver to save you from the drop in blood sugar.

But in someone who has diabetes, the liver releases more amount of sugar than needed which causes high blood sugar in the morning (Somogyi effect).

Normal glucose levels in the blood

 Fasting blood glucose (before meals) is 4.0-5.5 mmol/L.

 postprandial glucose (2 hours after a meal) 5.5-7 mmol/L.

these levels are the most recommended by WHO so, the question is how can we control gestational diabetes fasting glucose levels?

  • Go for a walk after evening meal as exercise increase glucose uptake by the cells and decreases blood glucose level.
  • Eat fewer carbs in the evening meal but it’s still important to eat carbs to avoid ketosis so, you shouldn’t cut it down completely.
  • Eating a bedtime snack which is high in protein and natural fat can benefit as well
  • Eating lighter breakfast to avoid the dawn phenomenon.
  • Apple cider vinegar can lower fasting glucose levels by 4%-6%.


  • Gestational diabetes fasting glucose level should be controlled through eating a healthy diet low in carbs, doing exercise, and drinking a lot of water.
  • Avoid eating too much food at bedtime.
  • If you have to eat in the evening we recommend protein and healthy fat.
  • Remember that’s for your health and your baby as well.
