Researches show that people who constantly have a poor night’s sleep are more prone to develop conditions that are linked to diabetes and heart disease. While those who are loud snorers as compared to quiet sleepers increased their risks of developing some type of metabolic syndromes such as diabetes, hypertension, and obesity. This fact also greatly increased up to 80% in those who find it troublesome to fall asleep.

Blood Sugar and Sleep Problems

Sleep influences your blood sugar levels and vice versa. This is a vicious cycle.

As the amount of your sleep decreases, your blood sugar increases. This escalates the issue. Since lack of sleep has been shown to escalate blood sugar levels and the risk of having diabetes. Higher blood sugar also mean less fat metabolism in the night and lesser during sleep.

Researchers have also found that those who slept less than 6 hours a night develops more blood sugar complications than those who have 8 hours of sleep.


Sleeplessness and restlessness affect more than your overall energy and mood. This generates chronic stress on your body. More stress results in higher blood sugar levels. A study was conducted to those people with type 1 diabetes showed that their sensitivity to insulin was reduced by 20% with just 4 hours of sleep as compared to after a full night of sleep.

When blood sugars are high, your kidneys will get rid of it through the process of urination. This will cause you to get out of bed to the bathroom more often at night which will result in inconsistent sleep patterns.  It can also wake you up because of being thirsty.


At about  3 or 4 in the morning, your body releases growth and other hormones to prepare your body for awakening. This is called the dawn phenomenon. It makes you to wake up to a high blood sugar level in the morning, even thought it was well-controlled the night prior.

So if you have diabetes, these changes might produce you to have a blood sugar spike in the morning.


However, if you have low blood glucose level, you may also wake up at night. It has been established that our body needs sugar to work properly. It’s a vital source of fuel. So when sugar level falls too low, a variety of problems ca occur which includes:
