Diabetes and Pregnancy: Causes and Management

Diabetes and Pregnancy: Causes and Management

Around 2-4% women will develop diabetes during pregnancy – you may hear this referred to as ‘gestational diabetes’, It’s a result of the hormonal changes in the body, and your body responding to how it needs to behave differently now you’re growing a baby.

For women who already have a diagnosis of diabetes prior to falling pregnant, they can find that some of their symptoms as a result of their condition can worsen. However, with proper management and medical support this is not normally too bad.

What is Diabetes?

The pancreas is an organ in the body that regulates the amount of sugar in our blood with the release of an enzyme called ‘insulin’.

Diabetes occurs when the pancreas is not able to perform its function properly. This leads to an increase in the level of sugar in the blood. This in turn can then lead to a number of health issues, especially if the condition is not managed correctly.

Depending on the type of diabetes you are diagnosed with, you may have to take regular medication which can be in the form of tablets, or a daily insulin injection. Many diabetics also have to monitor their blood sugar levels carefully to make sure they are within a ‘normal’ range’ and manage their diet to ensure they are not consuming too much sugar.
