Diabetes

Diabetic Care | The Oaks Family Practice, Carlow

Diabetes is a lifelong (chronic) condition caused by a lack, or insufficiency of insulin. Insulin is a hormone – a substance of vital importance that is made by your pancreas. Insulin acts like a key to open the doors into your cells, letting sugar (glucose) in.

 

With diabetes, the pancreas makes too little insulin to enable all the sugar in your blood to get into your muscle and other cells to produce energy. If sugar can’t get into the cells to be used, it builds up in the bloodstream. Therefore, diabetes is characterised by high blood sugar (glucose) levels.

Types of Diabetes
  • Type 1 diabetes tends to occur in childhood or early adult life, and always requires treatment with insulin injections. It is caused by the body’s own immune system destroying the insulin-making cells (beta-cells) of the pancreas.

  • Type 2 diabetes usually develops slowly in adulthood. It is progressive and can sometimes be treated with diet and exercise, but more often Type 2 diabetes may require anti-diabetic medicine and/or insulin injections.

 

More than three-quarters of people with diabetes have type 2 diabetes.The number of people with type 2 diabetes is rapidly increasing as it is commoner in the overweight and obese, which is itself a growing problem. The remainder have type 1 diabetes.

*Type 2 diabetes is included in the Chronic Disease Management programme. Type 1 is not included as it is generally managed by hospital units.

Pre-diabetes

Pre-diabetes is a condition where the amount of glucose (sugar) in the blood is higher than normal, but is not high enough for you to have a diagnosis of Type 2 diabetes. Pre-diabetes is the stage before a diagnosis of Type 2 diabetes.

  • Pre-diabetes is very treatable, but should be taken seriously. People with pre-diabetes have a high risk of developing Type 2 diabetes and heart disease.

  • If pre-diabetes is taken seriously, Type 2 diabetes can often be prevented or delayed. Being active, losing weight if you're overweight and eating healthy food can all make a huge difference.
