Gestational Diabetes

What is it? What are the symptoms? What are the treatments?

What is gestational diabetes?

Gestational Diabetes is diabetes which occurs during pregnancy. It most commonly occurs during the second or third trimester. During pregnancy, your body needs to produce more insulin to make sure the sugar in your blood is broken down to be used as energy. If you're not producing enough insulin, your blood sugar levels rise and can pass to your baby. It could cause your baby to grow very big if left untreated, which can cause problems when giving birth.

What are the symptoms of Gestational Diabetes?

Gestational Diabetes often has no symptoms but is picked up during routine tests in pregnancy. It can cause symptoms such as being thirsty all the time and having a dry mouth, the need to wee more frequently, tiredness, infections such as thrush, and blurred eyesight.

What are the treatments and remedies of Gestational Diabetes?

If you have Gestational Diabetes, it can be controlled by a specific diet or insulin injections if necessary. After the birth it normally goes away on it's own, but in some mums, diabetes may remain. You will be monitored carefully during and after pregnancy to check for this.
