Diabetes mellitus, sometimes known as DM, is a condition caused by a deficiency or the reduced effectiveness of insulin in the body. The are several types of diabetes mellitus but the most common are as follow:
Type 1 diabetes - this form of diabetes mellitus results from the body's inability to produce sufficient insulin. In the Untied Kingdom, approximately 1 in 300 people develop this type of diabetes at some stage during their lives.
Type 2 diabetes - this form of diabetes mellitus is caused by insufficient production of insulin in the pancreas, but also a resistance to the action of insulin in the body's cells. There are believed to be over two million people in the UK with this form of the disease. .
Gestational diabetes - this type of diabetes mellitus affects pregnant women who have never had diabetes before. Just under 5% of all pregnant women will develop this condition at some point during their pregnancy. Often, it will precede the development of type 2 diabetes after the birth.
Maturity onset diabetes of the young (MODY) - as the name suggests, this form of diabetes mellitus develops in children, or adults of a young age. It affects one to two per cent of people with diabetes and can often go unrecognized. It typically develops before the age of 25 years, often runs in families, and can usually be treated with lifestyle changes such as a healthier diet and increased physical activity.
Secondary diabetes - this is where diabetes mellitus develops as the result of another medical condition. It is often caused by damage to the pancreas, such as that caused by alcohol abuse, or by the impairment of insulin secretion from the pancreas.
