How does lack of sleep increase blood sugar?

Blood sugar levels usually rise while we sleep, usually between 4 and 8 a.m. In normal people, the pancreas secretes the hormone insulin and helps muscle cells, fat, liver and other organs absorb glucose, according to the health website Verywell Health (USA).

Lack of sleep will make diabetes harder to control

However, in people with diabetes, their bodies do not secrete enough insulin, so they cannot bring glucose into the cells. As a result, the glucose level in the blood increases, leading to hyperglycemia.

In addition, lack of sleep will cause the hormones that regulate appetite and metabolism to become imbalanced, leading to a spike in blood sugar. Studies show that lack of sleep will make the body's ability to secrete insulin less effective, increasing the risk of insulin resistance and causing diabetes to lose control.

Specifically, research evidence shows that people who sleep less than 6 hours/night are more likely to have irregular eating habits, snack more and prefer unhealthy foods. Lack of sleep will increase the hunger hormone ghrelin and decrease the satiety hormone leptin. This makes people who lack sleep feel hungrier and stimulate cravings for foods high in sugar and fat. As a result, they will easily gain weight.

In addition, blood sugar that is too high or low at night will also affect sleep and cause fatigue the next day. When blood sugar is high, the kidneys will find a way to eliminate this amount of sugar, leading to the feeling of needing to urinate at night. Not only that, high blood sugar also causes headaches and increased thirst, according to Verywell Health .
