There are several types of diabetes and they may be referred to by different names.
If you have type 1 diabetes the pancreas is unable to produce any insulin. This develops when most or all of your insulin producing cells are destroyed. This is the result of an autoimmune condition. That is the immune system, which exists to protect the body against infection and disease, turns against itself destroying the insulin- producing cells in the pancreas.
Type 1 Diabetes is most commonly diagnosed in childhood and adolescents, but it can appear in adults. The diabetes often develops quickly, over a few weeks, with marked weight loss and the person would become very ill without treatment.
If you have Type 2 Diabetes the pancreas is still making insulin but there is not enough for body’s needs or the insulin it produces is not used properly or there is a fault in the way the body responds to insulin. Known as insulin resistance. Therefore when the sugar (glucose) level in the blood rises there will either not be any insulin, or the insulin that you do produce will not work effectively to allow the sugar to be transported to the muscles to provide energy. The levels of sugar (glucose) in the blood therefore get higher (Hyperglycaemia). Hyperglycaemia makes you feel generally unwell and if left untreated can cause damage to blood vessels. Insulin is unable to do its job of allowing sugar to be absorbed from the blood.
Some women when they are pregnant develop a temporary type of diabetes called “gestational diabetes”. This is a type of diabetes usually occurs in pregnant women who are not known to already have diabetes. Read more
For most women the diabetes will stop as soon as the pregnancy is finished. However this may indicate a predisposition to develop diabetes in later life and consequently it is recommended that women who have had gestational diabetes should be screened.
This is a rare inherited form of diabetes mellitus in which there is a problem with the secretion of Insulin but the insulin action itself is normal or is only slightly faulty. It is caused by a number of genetic disorders that runs in some families, but can also be linked to obesity. This is type 2 diabetes that affects young people under 25 years of age. Insulin is not required to treat this condition.
