The blood sugar concentration or blood glucose level is the amount of glucose (sugar) present in the blood of a human.The body naturally regulates blood glucose levels as a part of metabolic homeostasis.Glucose is the primary source of energy for the body's cells,and blood lipids (in the form of fats and oils) are primarily a compact energy store. Glucose is transported from the intestines or liver to body cells via the bloodstream, and is made available for cell absorption via the hormone insulin, produced by the body primarily in the pancreas.Glucose levels are usually lowest in the morning, before the first meal of the day (termed "the fasting level"), and rise after meals for an hour or two by a few millimolar.
Blood sugar levels outside the normal range may be an indicator of a medical condition. Blood sugar levels outside the normal range may be an indicator of a medical condition.Diabetes mellitus is characterized by persistent hyperglycemia from any of several causes, and is the most prominent disease related to failure of blood sugar regulation.Intake of alcohol causes an initial surge in blood sugar, and later tends to cause levels to fall. Also, certain drugs can increase or decrease glucose levels.
A body's homeostatic mechanism, when operating normally, restores the blood sugar level to a narrow range of about 4.4 to 6.1 mmol/L
The normal blood glucose level (tested while fasting) for non-diabetics, should be between 70 and 100 milligrams per deciliter (mg/dL). The mean normal blood glucose level in humans is about 5.5 mM,however, this level fluctuates throughout the day. Blood sugar levels for those without diabetes and who are not fasting should be below 125 mg/dL.
The blood glucose target range for diabetics, should be 90–130 (mg/dL) before meals, and less than 180 mg/dL after meals (as measured by a blood glucose monitor).
Despite variable intervals between meals or occasional consumption of meals with substantial carbohydrate load, human blood levels tend to remain within the normal range. However, shortly after eating, the blood glucose level tends to remain within the normal range. However shortly after eating, blood glucose level may rise, in non-diabetic, temporarily upto 7.8 mmol/L or more.
Regulation:
Blood sugar regulation:
The body's homeostatic mechanism keeps blood glucose levels within a narrow range. It is composed of several interacting systems, of which hormone regulation is the most important.
There are two types of mutually antagonistic metabolic hormones affecting blood glucose levels:
1.catabolic hormones (such as glucagon, cortisol and catecholamines) which increase blood glucose;
2.anabolic hormone (insulin), which decreases blood glucose.
Low blood sugar
If blood sugar levels drop too low, a potentially fatal condition called hypoglycemia develops. Symptoms may include lethargy, impaired mental functioning; irritability; shaking, twitching, weakness in arm and leg muscles; pale complexion; sweating; paranoid or aggressive mentality and loss of consciousness.
In order to restore blood.It is far more dangerous to have too little glucose in the blood than too much, at least temporarily.Hypoglycemic episodes can vary greatly between persons and from time to time, both in severity and swiftness of onset.For severe cases, prompt medical assistance is essential, as damage to brain and other tissues and even death will result from sufficiently low blood-glucose levels.
High blood sugar
If blood sugar levels remain too high the body suppresses appetite over the short term. Long-term hyperglycemia causes many of the long-term health problems including heart disease, eye, kidney, and nerve damage.
The most common cause of hyperglycemia(high blood Suger) is diabetes. When diabetes is the cause, physicians typically recommend an anti-diabetic medication as treatment.Diet changes and exercise implementation may also be part of a treatment plan for diabetes. why not click on the link below to have more solution to your problem: http://l1nk.com/w83o5q
