QUESTION: At what blood glucose level should you go to hospital? Could you please explain why and what happens for either cases hyper and hypo glycemia?
ANSWER: Hi there,
It is very good that you want to understand the important things about the glucose metabolism, but first you have to learn the basic things. For your information, the normal blood glucose level is 3.5 - 6.1mmol/l or 64.8 – 104.4 mg/dl, depending on the unit of measurement.
However, when the result of the blood glucose test is lower than 3.5mmol/l, respectively 64.8mg/dl, you are in the state of hypoglycemia. In this situation, there is not enough glucose, which can be transformed into energy.
In addition, some of the cells in the human body are requiring a lot of energy, like the brain cells. These cells are not able to execute their function, when the amount of glucose in plasma is low.
Because of this, when your blood glucose fall to 3.0mmol/l, they are stimulating your heart to beat faster, providing more blood with high glucose.
It is good to know that in this situation you may feel your own heartbeat and to start experiencing headaches.
Moreover, the brain cells are stimulating not only the heart to beat faster, but also your gastrointestinal tract to start metabolizing the food, leading to a feeling of hunger.
The best option for you is to eat something sweet immediately, when you notice hunger, headache and the palpitations. The chocolate for example, is containing a lot of sugar and respectively energy, helps you perfectly fight against hypoglycemia.
In case you don’t take actions and your blood glucose level continues to lower more than 2.2mmo/l (40mg/dl), seizures might occur.
Very often, this situation is related to losing consciousness and accidental falls, which requires instant medical attention.
