Sugar is a good slave but a very taxing master. Sugar is one of the main sources of energy or fuel for the body. Now, our body extracts sugar from the meals we have. Sugar can be carbohydrates which is a complex form of this stimulating source or just plain sugar. It is rather interesting to note that our body always keeps a buffer stock of sugar in the liver. This vital storehouse of sugar is called glycogen. This storage of sugar provides ready backup of sugar during exigencies when the body badly needs to look for sugar reinforcements. Mention may be made of some really trying times as too much of physical labor or during long periods of fasting. Further, the body releases the requisite additional quota of sugar via a complex biochemical procedure. This method is known as gluco-neo-genesis. Its simplest meaning is to produce new sugar. What is more, the process changes the glycogen into sugar. So we see how important sugar is for our body. Hypoglycemia happens whenever the body fails to regulate or supply such emergency sugar reinforcements. These problems appear due to malfunctioning of our pancreas. During such times, the natural capacity of the body to produce insulin gets affected. Our body’s blood sugar level is automatically kept under control by insulin. This hormone secreted by the pancreas carries out the job by lowering the blood sugar level the moment it crosses the danger stage. In a normal human being, the pancreas is the sentinel ever on vigil against the attacks of excessive blood sugar. The method is akin to the radiator fan in your car which starts automatically whenever the engine gets heated up beyond the requisite level. Hypoglycemia is intimately connected with the typical metabolic ailment known as Diabetes mellitus. The ailment, diabetes, can definitely be kept under control but cannot be cured by the modern-day medications. It is a medical state that is chronic. In simple words, diabetes or hypoglycemia remains a person’s lifetime mate. Diabetics usually posses high levels of sugar in their blood stream. Incidentally in the good olden days, diabetes was initially identified with ‘sweet urine’ and too much loss of muscles. Such sweet urine is the result of hypoglycemia when the body produces glucose more than its requirement. What is more, the excess glucose gets circulated in the blood. Only when the pancreas is functioning normally can its insulin hormone control the high level of blood sugar. Patients suffering from diabetics (Types 1 and 2) complain of hypoglycemia. A person suffering from hypoglycemia generally encounters problems in controlling the blood sugar level. This again results because that person’s pancreas failed to either produce the sufficient quantity of insulin or totally failed to produce any insulin. The consequence is hyperglycemia. There are many causes of hypoglycemia. Diabetics undergoing long periods of fasting can have hypoglycemia. This happens because their levels of insulin circulate fast. And, the fasting phase suddenly brings down this high circulating level. Moreover, certain drugs can also trigger off hypoglycemia. Even those persons who have inbuilt resistance to insulin may complain of hypoglycemia. Hypoglycemia can be caused also by certain tumors which produce insulin. Such tumors are called insulinomas.
