There are two main types of diabetes, Type 1 and Type 2.

Type 1 Diabetes is when the pancreas, a small gland behind the stomach, is unable to produce any insulin at all, a hormone which regulates the levels of glucose in the blood. When the amount of glucose in the blood is too high, it can cause serious damage to the body's organs. Type 1 Diabetes typically develops before the age of 40, but is usually developed during the teenage years and people with Type 1 are required to take insulin injections for the rest of their lives.

Type 2 Diabetes is much more common than Type 1 Diabetes. It occurs when the body is unable to produce enough insulin to function properly, or the cells in the body do not react to insulin, known as insulin resistance. Type 2 Diabetes often develops in people over the age of 40 but an increasing number of people from all ethnic groups are developing the condition. Additionally, people who are overweight or obese (those with a Body Mass Index (BMI) of 30 or higher) are at a much greater risk of developing Type 2 Diabetes. This s because fat around the abdomen releases chemicals which can cause upset to the body's cardiovascular and metabolic systems. Luckily, reducing your body weight by as little as 5% and participating in regular exercise can actually reduce a person's risk of developing diabetes by more than 50%.
