I’m sure you know that the glucose in your blood is the major source of energy. So, when its concentration is low, there is reduced energy supply your body starts to suffer.
Generally when there is not enough glucose you feel weak, unable to stand up from the chair, along with sweating and tenderness. I think that under shaky you mean, those things mentioned above.
Besides this, when you are on very restricted low-sugar diet, the carb intake is very low and sometimes not enough to ensure you normal lifestyle.
So, I want you to do two things about your condition:
1. First is to measure your blood glucose concentration at the moment when you feel shaky and
2. second- to take something sweet (candy) everywhere with you.
According to this, when you see that your blood glucose concentration is low, because of the shaky sensation, you have to eat a piece of chocolate or something else, which can rise your blood glucose level.
However, I want to remind you that having low blood glucose concentration is not physiological for you.
You and your baby are suffering, which means that you have to take measures in purpose not to have low blood glucose level, but a blood glucose concentration which is between 3.5 and 6.1mmol/l.
In addition, you haven’t mentioned anything about drug treatment. I want to remind you, that the inappropriate usage of certain blood glucose lowering drugs leads to hypoglycemia (low blood glucose level).
At last I want you to discuss with your doctor your general condition and how is the pregnancy going.
You have to know that the uncontrolled gestational diabetes can cause a lot of damages to you and to your baby. So, you have to be under strict medical supervision.
