Why is my blood sugar high even when I am fasting?

These days, when you're very interested in health, everyone checks their fasting blood sugar levels a lot, right?

Fasting blood sugar refers to the blood glucose level measured after an 8-hour fast.

Normal values are usually 70 to 100 mg/dL, and diabetes is diagnosed if fasting blood sugar levels are 126 mg/dL or higher.

Fasting blood sugar impairment is in the range of 100 to 125 mg/dL, which is higher than normal but lower than the diagnostic criteria for diabetes.

It refers to a situation with potential danger.

 

 

I haven't eaten anything, so why is my fasting blood sugar high???

There are six reasons as follows.

 

Insulin resistance

When insulin is normally secreted but the body cannot utilize it properly, leading to poor blood sugar control

 

○ Dawn phenomenon

It has the characteristic of starting to increase from early dawn (3 a.m.), and due to the natural hormonal changes that occur in the early morning, fasting blood sugar levels are high.

 

○ Mosquito breeding phenomenon

The phenomenon called reactive hyperglycemia after nocturnal hypoglycemia is a condition where, if a hypoglycemic state occurs overnight, the body compensates by rapidly raising blood sugar levels.

 

Overweight

If you overeat foods containing carbohydrates, the insulin receptors on cell membranes do not respond, preventing glucose from being sent into the cells, which causes blood sugar levels to rise.

 

Stress

Continuous stress causes elevated cortisol levels, making blood sugar regulation difficult.

 

Lack of sleep

While sleeping, glucose is produced, and it takes a long time for this glucose to be absorbed into the body.

 

 

To manage fasting blood sugar levels, it is advisable to have regular meals and a balanced diet, avoid high-fat and high-cholesterol foods, and prefer complex carbohydrates that take longer to digest over simple sugars. Additionally, maintaining consistent exercise is beneficial.

They say it's the best way to control fasting blood sugar.

I will also try to take care of my health in the same way.
