Diabetes is a metabolic disorder when the body cells do not assimilate normally a sugar (glucose) from the blood. This means the sugar in blood increases chronically. Diabetes is a very dangerous disease, so get familiarized with its 8 main symptoms to reveal the illness on the early stage.
Hunger and fatigue. A brain needs glucose for correct functioning. After eating the concentration of glucose in the blood increases. But if insulin sensitivity is broken, the glucose isn’t supplied to the brain and turns into fat tissue increasing further the insulin resistance. The brain still requires food, especially a sweet one. So people eat more and become more overweight. Increasing fatigue develops because both muscles and the brain do not receive enough glucose. Because of constant weakness and increased appetite a human with diabetes moves less and the weight continues to grow aggravating the overall situation.
