Blood glucose screening is a procedure that measures the amount of glucose, or sugar, in your blood. This test is often used to indicate whether someone may have diabetes. However, people with diabetes can also use this test to manage their condition.

What is diabetes?

Diabetes is a condition characterized by high levels of glucose in the blood. It occurs when there is a lack or insufficiency of the hormone insulin, which is produced by the pancreas. Insulin is responsible for the way that glucose is used in your body. Insulin allows glucose into the cells in the body to produce energy. A lack of insulin results in a build-up of glucose in the bloodstream which becomes too high.

There are two types of diabetes – type 1 and type 2. Type 1 diabetes (insulin dependent diabetes) usually occurs during childhood or before the age of 35. People who have type 1 diabetes produce insufficient insulin and therefore must treat their diabetes by injecting insulin in order to regulate their blood sugar level. Type 2 diabetes (non-insulin dependent diabetes) is more common in people over the age of 40, especially during old age. Type 2 diabetes is usually associated with people being overweight which means that diet, exercise and weight loss can help to control the blood sugar levels. However, if weight loss is not enough, medication or additional insulin may be required.

Symptoms of diabetes:

  • Excessive thirst
  • Tiredness
  • Lack of energy
  • Weight loss
  • Frequent passing of urine
  • Blurring vision
