What is diabetes?
Diabetes is a common condition in which the amount of glucose (sugar) in the blood is too high.
This can happen when the body does not produce enough insulin or the insulin it produces is not
working effectively. Insulin is the hormone needed to convert sugar ('blood glucose') to energy
and controls blood glucose levels. There are two types of diabetes.
Type I diabetes
Type I diabetes occurs when the pancreas stops producing insulin altogether. It usually occurs in
younger people but can occur at any age. It is treated with a healthy diet and regular insulin injections.
Type 2 diabetes
Type 2 diabetes is the most common form of diabetes. It occurs when the body is producing some insulin
but either this is not enough for its needs or the insulin is not working effectively. This type of
diabetes tends to run in families. It often occurs in older people or people who are
overweight. It is treated with a healthy diet although in some instances this may
be used in conjunction with either tablets or insulin injections.
What are the effects of diabetes?
There is no cure for diabetes but there are effective treatments. Early diagnosis and treatment is
important to relieve symptoms and reduce the chances of developing more serious health problems.
Diabetes can seriously affect your heart, eyes, kidneys, nerves and feet. Heart disease causes 80%
of all deaths in diabetics, mainly due to heart attacks and because almost 50% of diabetics have
high cholesterol levels. However, with the correct treatment you have less risk of developing these
problems. Keeping blood glucose levels as near to normal as possible and tightly controlling blood
pressure and cholesterol levels help keep you healthy in the long term.
How can I tell if I have diabetes?
The symptoms of diabetes are a result of blood glucose levels being too high. Type I diabetes develops
at a faster rate than Type 2 diabetes and the symptoms are usually more obvious. Some people may not
realise that they have any 'diabetic symptoms'.
