Blood sugar level in the body needs to be maintained at a certain levels; otherwise it can cause major problems. Let us explore the signs and symptoms of high & low blood sugar.

Symptoms Of Sugar

Blood sugar refers to the glucose that is present in the blood of an individual. It is transported from the intestines to body cells, through the bloodstream. Blood sugar serves as one of the most important sources of energy for the body. The concentration of blood sugar, also known as glucose level, in the body is regulated with the help of insulin. Blood sugar level falling in the range of 70-120 is considered healthy. If the level persists to be anywhere above or below it, then it means that the person is suffering from either high or low blood sugar level.
If, for any reasons, the level of insulin in the body increases, it leads to a drop in the sugar levels, in other words, the condition gives rise to low blood sugar, which is medically termed as hypoglycemia. On the other hand, if there is a decrease in the insulin levels, it may lead to high blood sugar levels, which is medically termed as hyperglycemia. In either case, it is necessary to act quickly and seeks doctor’s advice, because both the conditions might trigger a number of health problems, if left untreated for a long time. In the following lines, we will tell you the causes and symptoms of high as well as low blood sugar.
