QUESTION: recently i have episodes of tachycardia in 2 months time both @ same time around 8:45 in the morning.
Is there any relation between low fasting blood sugar and tachycardia?
ANSWER: Hi there,
It is good that you are monitoring your blood glucose, especially in the morning. I want to remind you that the normal blood glucose level is between 64.8 and 104.4 mg/dl, which means that your blood glucose level is absolutely normal.
However, there are differences in the metabolism of every individual. For example, a blood glucose level of 70 mg/dl is normal for one person, but for another person, this level is considered low.
Generally, the active individuals are requiring more energy, respectively glucose, to live normal life. Because of this, a blood glucose level of 70 mg/dl is low for them and they are not feeling comfortable, just like you.
Furthermore, I want you to understand that there is a connection between this blood glucose level and tachycardia. Generally, tachycardia is observed when the organism needs more glucose, a condition known as hypoglycemia. Obviously, your organism needs more glucose in the morning.
As you probably know, all the cells in the organism are requiring glucose to execute their normal functions. We can divide the cells in two groups: first group - very active cells, which are requiring a lot of glucose and the second group - not so active, which are requiring small amount of glucose.
The most active cells in the human body are the nerve cells, which require a lot of glucose and besides this, they don’t have a glucose store. Because of this fact, the organism has to ensure them as much glucose as they need.
The concentration of glucose is alike everywhere in the blood, and for that reason, the only way to ensure more glucose to certain area is to increase the blood flow that goes there.
As I mentioned, the nerve cells, especially the brain, are requiring a lot of glucose. When the brain feels that the glucose is not enough, he sends a signal to the heart to start pumping harder and faster (tachycardia). In this way, the heart will ensure more blood, full of glucose for the brain.
