Can someone explain how Gestational Diabetes happens?

I'm currently pregnant and my doctor mentioned that I should be aware of Gestational Diabetes. I've heard about it before, but I'm not exactly sure how it develops. Can anyone give me some insights?

Gestational Diabetes is caused by the hormonal changes during pregnancy. The placenta produces hormones that can make it harder for insulin to do its job, leading to high blood sugar levels. It usually occurs in the second or third trimester.

While it's not entirely clear why some women develop Gestational Diabetes and others don't, there are certain risk factors. These include being overweight, having a family history of diabetes, or having had Gestational Diabetes in a previous pregnancy.

The good news is that Gestational Diabetes can often be managed through a healthy diet and regular exercise. It's important to monitor blood sugar levels closely and consult with your healthcare provider about any necessary lifestyle changes or treatments.
