About Diabetes

About DiabetesDiabetes mellitus, commonly referred to as diabetes, is a medical condition associated with abnormally high levels of glucose (or sugar) in the blood (hyperglycaemia).

  • Glucose is a type of sugar found in certain foods such as honey and some, but not all, fruits. It is also the form of sugar that all sugary and starchy foods are converted to in the body after digestion. Glucose is used by the body to make energy.
  • Normally, blood glucose levels are tightly controlled by insulin, a chemical signalling substance (hormone) that is produced by a gland near your stomach called the pancreas.
  • Insulin lowers the blood glucose level because it stimulates the body to make use of glucose.
  • When the amount of glucose in the blood increases, for example, after eating food, insulin is released from the pancreas to normalise the glucose level. However, in patients with diabetes mellitus, the elevated glucose levels cannot be normalised. This causes abnormally high levels of blood glucose, which ultimately leads to the presence of glucose in the urine (glucosuria).
