Introduction
If you have recently been diagnosed with Type 2 diabetes, you may be thinking that you have been given bad news. You may think life as you have enjoyed it is at an end and that you are faced with a future of deterioration. This does not have to be the case at all. Type 2 diabetes is a condition to take seriously, but the diagnosis gives you the opportunity to get it under control and to reduce your risk of developing complications. Indeed, control it well and you will probably feel better than you have done for some time.
You may not, in fact, have been diagnosed with the condition, but been told that you have pre-diabetes. This means that you are at risk of developing it, but as yet you have not done so. The very good news is that you can reverse that risk and prevent yourself from developing Type 2 diabetes.
Diabetes is a condition that is increasing in incidence every year around the globe. It is linked with rising obesity levels, greater inactivity and the consumption of a diet that frankly predisposes people to develop diabetes.
As we shall see in Chapter 1 ( An overview of diabetes ) diabetes mellitus is a lifelong disorder of carbohydrate metabolism that occurs when the pancreas does not produce enough insulin, or when the body does not respond to its own insulin. While I am going to consider the different types, the overall emphasis of the book is on understanding and dealing with Type 2 diabetes.
The book falls naturally into two parts. Part 1 is about understanding Type 2 diabetes, beginning with some background information about the way the bodys metabolism works and how the body handles glucose. Then we shall look at how things can go wrong and what sort of complications can occur. This is important, because Type 2 diabetes can affect many of the bodys systems, particularly the circulation and heart, the eyes, the kidneys and the nervous system. You need to know about all of these in order to reduce your risk of developing such complications.
Part 2 will look at how diabetes is diagnosed and how you and your doctor can keep it under control. We will look at the tests and investigations you should have, and we will look at the way that diet, exercise and possibly drugs can maximise your health.
The diagnosis is not bad news; it is a warning that things are not working as they should, and by altering lifestyle and developing a positive attitude towards the condition and your future, you can live well with your Type 2 diabetes.
Part One
UNDERSTANDING
TYPE 2 DIABETES
Type 2 diabetes does not always produce the common symptoms, such as increased thirst. This is very important, because many people with Type 2 diabetes have no symptoms at all, or are not particularly bothered by them for years. They may not know that they have diabetes until they have a blood-glucose test done on routine examination at their doctors surgery. Because of this tendency for the condition to smoulder on unrecognised, if you believe that you are at risk of developing it, you should have a blood test.
Chapter 1
An overview of diabetes
Diabetes mellitus is a lifelong disorder of carbohydrate metabolism that occurs when the pancreas does not produce enough insulin or when the tissues do not respond to the bodys own insulin.
The characteristic feature of diabetes in an undiagnosed or untreated form is excess thirst and increased tendency to pass urine. This is the result of raised blood-glucose levels. Over time this can lead to serious damage to various body systems.
Common symptoms of diabetes
- Increased thirst
- Increased frequency of urination, especially at night
- Excessive tiredness
- Weight loss and loss of muscle bulk
- Itching around the genitals or frequent episodes of thrush
- Wounds or cuts are slow to heal
- Blurred vision, as a result of the lens of the eyes becoming dry
Types of diabetes
There are two main types of diabetes, which make up the vast majority of cases. They share the name diabetes mellitus, but each type has its own features, causes and indicated treatments.
Both types affect the blood-glucose levels and both produce complications unless they are adequately treated. These complications can significantly impair health and even lead to early death.
Type 1 diabetes
This is characterised by lack of insulin production. It used to be called juvenile onset diabetes or insulin dependent diabetes. This was because it tended to occur in children and young adults. It requires treatment with insulin.
It is an autoimmune condition in which the immune system attacks the insulin-producing cells in the pancreas. There is therefore a deficiency of insulin and the individual will have to take insulin injections for the rest of his or her life. It is not possible at this stage in time to prevent Type 1 diabetes from developing. Type 1 diabetes accounts for about ten per cent of all diabetes cases worldwide.
