One More Proof, Sleep Deprivation Causes Diabetes!
In his study, Researchers monitored 21 healthy people, who all live in a sleep laboratory for nearly six weeks, in which the sleep cycle, diet and activities all controlled by the researcher.
The findings showed that participants were only allowed to sleep about six hours a night and shifting sleep / wake cycle have blood sugar levels higher and tend to slow down the metabolic process.
"The level of glucose is higher for long periods of time on some of the participants could be increased to prediabetes," said the researcher. The findings were published on April 11, 2012 in the journal Science Translational Medicine.
"There are many things that play a role regarding the relationship between lack of sleep and obesity," said Dr. Vivian Fonseca, chief of endocrinology at Tulane University School of Medicine, who was not involved in the study.
Fonseca said the new study shows that hormone levels in the body are likely to be altered by sleep deprivation. This could help explain why those who sleep less are very susceptible to obesity.
Sleep and blood sugar
In the study, researchers conducted a blood test to measure levels of several hormones, including insulin, cortisol (stress-related), and leptin and ghrelin (which corresponds to regulate appetite).
They found that disrupted sleep schedule caused a 32 percent decrease in the amount of insulin that is released in the body after eating. Insulin is a key hormone in the regulation of blood sugar.
"The drop in insulin levels is one of the explanations of how disruption or lack of sleep can cause diabetes," said Lisa Rafalson, a professor of pediatrics and family medicine at the University at Buffalo.
Rafalson revealed an increase in stress hormones that always makes the body awake can cause hormonal imbalances.
"Insulin can not do its job efficiently, so you end up getting excess glucose remaining in the blood stream," he said.
While the latest findings, researchers did not see any change in hormone levels gheriln (which increases appetite) in participants who slept less. Whereas some previous studies have shown that lack of sleep can lead to higher levels of the hormone ghrelin and leptin were lower.
Related to these findings, Fonseca said, researchers need to find out whether there is a solution to prevent the increased risk of diabetes in addition to sleep more.
"The fact is many people are losing sleep because of their work. We need to identify whether there are other things they can do to fix it, "he said. (Source: FOX NEWS)
