Why Do We Need Sugar In Our Blood?

Humans need a certain amount of sugar in the blood to function properly. Blood sugar known more precisely as glucose energy to the brain which controls nearly all aspects of human activity. Unlike muscles which can derive energy from fat you eat the brain requires glucose to power their business. Therefore keeping blood sugar levels at optimal levels the best way to ensure that your brain has all the energy it needs
What is Normal?
A healthy blood sugar levels vary significantly during the day according to William C. Shiel Jr. who is editor of MedicineNet. com. It is normal for someone who has just woken up and not yet eaten breakfast would be between 80 mg / dl (milligrams per deciliter) and 120 mg / dl and a similar number would be normal before each meal of the day. A normal reading two hours after a meal would be near 160 mg / dl or lower while the normal bedtime should be between 100 and 140 mg / dl according Shiel.
abnormal levels
blood sugar falls significantly outside areas defined by Shiel is abnormal and signal to the doctor that something is wrong. Too much blood sugar constitutes a condition called hyperglycemia and it is particularly dangerous for those who have diabetes. Abnormally low levels of blood sugar constitutes hypoglycemia which is also a condition that diabetics must take great care to avoid.
hyperglycemia
Diabetics must carefully monitor blood sugar levels to avoid symptoms of hyperglycemia which can lead to diabetic coma or ketoacidosis if allowed to go unchecked. Symptoms of hyperglycemia in diabetics may include increased urination and extreme thirstiness. For patients with type 1 diabetes this could be a sign that they failed to take enough insulin while those with type 2 diabetes may mean that insulin levels are almost normal but not be as effective as they should be according to the American Diabetes Association. Exercise can help to get diabetics’ blood sugar levels down to acceptable levels but should not be attempted if your blood sugar is 240 mg / dl or higher and ketones are present in urine. If these conditions are present you should get immediate medical attention sought.
hypoglycemia
The symptoms of low blood sugar include anxiety confusion dizziness difficulty speaking hunger nervousness tremor sleepiness excessive sweating and weakness according to the National Diabetes Information Clearinghouse. Diabetics blood sugar readings are below 70 mg / dl should immediately take one of the following to adjust blood sugar levels higher: 1 tbsp. of honey or sugar three or four glucose tablets 4 oz. of fruit juice or non-diet soda 8 oz. of milk or five or six pieces of hard candy.
Tips for nondiabetics
Nondiabetics are far less likely to suffer from hyperglycemia because self-regulating mechanisms of the body usually does a very good job of keeping blood sugar levels under danger point. But in the rare event that a non-diabetic patients suffering from hyperglycemia symptoms — frequent urination and thirstiness — be the same. Similarly is hypoglycemia relatively rare among nondiabetics but would provide similar symptoms if your blood sugar was abnormally low. A non-diabetics experience any of these conditions should consult a doctor immediately.
