There are six main types of diabetes:

- Type 1 – The immune system attacks insulin-producing cells in the pancreas
- Type 2 – The body makes insulin but can't use it properly
- Gestational – Develops during pregnancy
- Double diabetes (Type 1.5/LADA) – A mix of both Type 1 and Type 2
- Monogenic – Caused by a mutation in a single gene

Here's what the numbers look like for close relatives:

- Both parents with Type 2 = risk rises to around 70%

The good news is that genetics aren't the whole story. Lifestyle factors like maintaining a healthy weight, staying active, and eating well can significantly reduce the risk — even with a family history.

It's worth mentioning to her doctor so they can monitor her blood sugar levels as she gets older. A DiabetesTeam member shared that their father and grandmother both had Type 2 diabetes, and they themselves have lived with it for over 25 years — so early awareness really does matter!
