Type 2 diabetes is a condition in which the body can not produce enough insulin to regulate blood sugar levels. Over time, an undetected blood sugar level could increase a person's risk of developing life-threatening complications such as heart disease. The blood sugar level changes constantly during the day and in the evening. In fact, night time is when the blood sugar level could rise to dangerous levels overnight. That's why eating at bedtime is crucial.
If a person sleeps at night, the amount of glucose equals the amount of glucose that is released by the liver, which is why the blood sugar level should theoretically be at the same level.
However, there are two processes that occur during the evening that can alter these levels and potentially cause major problems for people with type 2 diabetes.
The Mayo Clinic stated, "The phenomenon of dawn, also known as twilight, is the term used to describe an abnormal rise in early morning blood sugar ̵
"Some researchers believe that the natural release of the so-called counter takes place overnight -regulatory hormones – including growth hormone, cortisol, glycogen and adrenaline – increase insulin resistance and cause an increase in blood sugar.
" High morning blood sugar can also caused by insufficient insulin the night before, Efficient antidiabetic doses or the consumption of carbohydrate snacks at bedtime.
Avoiding heavy carbohydrate foods is essential for nocturnal snacks.
This includes bread, starchy vegetables, pasta, fries or crackers.  Doctor Michael Mosley said, "If you eat lots of carbohydrates and sugars, especially those that have no fiber and are absorbed quickly, they will quickly increase your blood sugar levels.
The pancreas then releases insulin into the bloodstream to lower the level again and store the excess sugar as fat.
"Too much stored fat, especially visceral fat, can lead to serious health problems." It is recommended to use foods high in fiber and low in fat to keep blood sugar levels stable.
These include snacks such as nuts, certain fruits, vegetables or legumes.
A 2003 study investigated the effects of sugar on bedtime snack composition for the prevention of nocturnal hypolgykaemia in adults with diabetes.
The aim was to determine the influence of four bedtime snack compositions on nocturnal glycemic control.
The result was that the need for nocturnal snacks is beneficial in reducing nocturnal hypoglycemia.
