Blood Glucose / Sugar Level

What are Hypo and Hyperglycemia?

High blood sugar (hyperglycemia) is where the level of sugar in your blood is too high. It mainly affects people with diabetes and can be serious if not treated.

Hypoglycemia is a condition in which your blood sugar (glucose) level is lower than the standard range. Glucose is your body’s main energy source.

Glycemia, also known as blood sugar level, blood sugar concentration, or blood glucose level is the measure of glucose concentrated in the blood of humans or other animals. Approximately 4 grams of glucose, a simple sugar, is present in the blood of a 70 kg (154 lb) human at all times. The body tightly regulates blood glucose levels as a part of metabolic homeostasis. Glucose is stored in skeletal muscle and liver cells in the form of glycogen; in fasting individuals, blood glucose is maintained at a constant level at the expense of glycogen stores in the liver and skeletal muscle.

In humans, a blood glucose level of 4 grams, or about a teaspoon, is critical for normal function in a number of tissues, and the human brain consumes approximately 60% of blood glucose in fasting, sedentary individuals. A persistent elevation in blood glucose leads to glucose toxicity, which contributes to cell dysfunction and the pathology grouped together as complications of diabetes. Glucose can be transported from the intestines or liver to other tissues in the body via the bloodstream. Cellular glucose uptake is primarily regulated by insulin, a hormone produced in the pancreas.

Glucose levels are usually lowest in the morning, before the first meal of the day, and rise after meals for an hour or two by a few millimoles. Blood sugar levels outside the normal range may be an indicator of a medical condition. A persistently high level is referred to as hyperglycemia; low levels are referred to as hypoglycemia. Diabetes mellitus is characterized by persistent hyperglycemia from any of several causes, and it is the most prominent disease related to the failure of blood sugar regulation. There are different methods of testing and measuring blood sugar levels.

Symptoms of Low / High Blood Sugar

How you react to low blood sugar may not be the same as how someone else with low blood sugar reacts. It’s important to know your signs. Common symptoms may include:

  • Fast heartbeat
  • Shaking
  • Sweating
  • Nervousness or anxiety
  • Irritability or confusion
  • Dizziness
  • Hunger

Symptoms of high blood sugar usually come on gradually and may only start when your blood sugar level gets very high. Common symptoms include:

  • Feeling very thirsty
  • Peeing a lot
  • Feeling weak or tired
  • Blurred vision
  • Losing weight
