How Does Insulin Help Controlling Blood Sugar Levels?

Insulin is a naturally-occurring hormone secreted by the pancreas. The body cells need insulin to take away and use glucose from the blood. From glucose the cells fabricate the energy that they require to perform their functions. Researchers first gave an active extract of the pancreas, which contains insulin to a young diabetic in 1922, and the Food & Drug Administration (FDA) approved insulin in 1939. At that time, insulin meant for cure was derived from beef and pork pancreas plus recombinant (human) technology. The FDA approved the first recombinant human insulin in 1982.


Insulin is an anabolic polypeptide endocrine, which regulate carbohydrate metabolic process. It is a fast-acting medication that begins to work very quickly. After making use of insulin, you should eat a meal within 5 to 10 minutes. But, it is important to follow up doctor’s instructions.
Despite being the primary agent in carbohydrate physiological condition, it also has effects on fat metamorphosis and it changes the livers action in accumulating or discharging glucose, and in processing blood lipids, and in other tissues such as fat and muscle. The insulin quantity in circulation has extremely widespread have an effect on the whole body. Insulin cannot be taken in the oral form. Unlike many medicines, insulin cannot be taken in oral form. It is taken as subcutaneous injections by disposable syringes with needles, an insulin pump, or by repeated-use insulin pens with the help of needles.

Insulin is secreted by cells groups within the pancreas known as islet cells. The molecular weight of Insulin is 5808 Daltons, and it is made of 51 amino acid residues. Insulin is a quite small protein, which is composed of two chains held jointly by disulfide bonds. Medically, Insulin is used to treat some types of diabetes mellitus. Patients having Type-1 diabetes depend on external insulin for proper survival due to the nonexistence of the hormone. Patients with Type-2 diabetes mellitus have insulin resistance, fairly low insulin production, or both; some type 2 diabetics finally have need of insulin when other treatments become unacceptable in controlling the blood glucose levels.


The actions of insulin on overall human metabolic process include control of cellular intake of certain substances, conspicuously glucose in muscle and adipose tissue, growth of DNA replication and protein synthesis by controlling amino acid ingestion and modification of the activity of various enzymes. The insulin actions on body cells include increased fatty acid synthesis, increased glycogen synthesis, augments esterification of fatty acids, abridged proteinolysis, decreased lipolysis, decreased gluconeogenesis, increased uptake of amino acid, arterial muscle tone, and increased potassium uptake.


Take care to keep your blood sugar from getting too low, as it results in hypoglycemia. The main symptoms of hypoglycemia are headache, nausea, hunger, confusion, drowsiness, weakness, dizziness, blurred vision, fast heartbeat, sweating, tremor, or trouble concentrating. Too high blood sugar levels also results in hyperglycemia. Its main symptoms include increased thirst, loss of appetite, increased urination, nausea, vomiting, drowsiness, dry skin, and dry mouth. Monitor your blood sugar levels and ask the physician how to adjust insulin doses if the blood sugar levels are too high or too low.
